Guide to Final Cut Pro Internal Tools

Did you know Final Cut Pro has a hidden menu? Just hold down Cmd + Option + Shift and click the Tools menu. You should now see a new menu item called Internal Tools.



This is a debug menu used by the developers of FCP, but it actually has some uses for us mere mortals as well. It's especially useful for plugin developers and system troubleshooters, but some features benefit all users. Here is a rundown of what's in the menu.

Adjust Windows

When you open the Audio Mixer, Frame Viewer and several other tools in the Tools menu, they open in a tabbed window called the Toolbench. This normally appears on top of the Viewer and is hidden behind it when you select the Viewer again.

The Adjust Windows menu item adjusts the window layout so the Toolbench can fit in without being obscured by other windows. If you don't have the Toolbench open when you click this item, it will leave a gap in your window layout.

After


To restore the default window configuration again, press Ctrl+U.

App / Perf Info

This generates a text file containing just about everything you could ever wish to know about your FCP configuration.



Probably the most useful part is the Project / Sequence Information section. This gives various statistics about your project including the total number of clips placed in your timeline and the proportion of those clips that were unique. It will even tell you how many edits you performed per minute (don't let your boss see this!).

Log OpenGL Profile Costs

This function displays timing information about OpenGL Profiling in the Console. It will do nothing until you start profiling (see the Statistics section below), at which point it tells you how long (in ms) it took your machine to process the given frame sizes and codecs.



One thing I noticed about this is that it takes a fair while for the data to be posted to the Console - around 1-2 minutes.

Log VM Footprint

This outputs the current memory usage to the Console.



Resident refers to data in physical memory, Virtual refers to data on the disk ready to be copied into main memory as required. Note that the system often assigns more virtual memory space than it needs, so not all of that space will actually be used. So if you see a ridiculous number like 4 GB, it is not necessarily a cause for alarm.

Movie Dumpster

This one crashes Final Cut Pro for me, so I wasn't able to ascertain exactly what it does. However, Apple offers a tool called Dumpster on their developer site which gives you a large amount of technical information about a specific movie clip. I would imagine this would be similar if it worked.

Playback Meter

This will show you how your media drives are performing, and is probably the most useful tool in the menu.



If you are not using a RAID, only the audio bars will work. Everything is fine while the bar is green, but if it turns yellow or red, this is an indication that your computer cannot keep up.

Screen Size Override

This allows you to fool Final Cut Pro into thinking that you have a different-sized monitor.

Just select the desired resolution from the pull down menus and press Ctrl + U to automatically resize the windows to the new dimensions.



If you mess things up, just restart Final Cut Pro and press Ctrl + U to restore the windows to the correct position for your screen resolution.

Statistics

This displays a lot of technical information about what's going on under the hood of FCP.



For instance, select the Render check box, drag the playhead across the timeline and then click the Average button. This will average the times taken to perform the various function calls required to render the image to the screen. If your system is getting sluggish, you may find it useful to use the Averages function to see which areas are taking a long time to process.

Most of the checkboxes are self-explanatory so I won't elaborate on them here. However, I would advise selecting them one at a time otherwise you'll end up with an overflow of information.

If you want to clear the text box, click Reset. Copy copies the entire data to the clipboard and Copy Avg copies only the averages. Unset All deselects all of the checkboxes.

Both Auto Profile and RT Verify go through each item in the Browser (video clips, sequences, images, etc), playing each one four times and averaging the data. Sequences take longer because the profiler initially tests with only the V1 track enabled, and then gradually enables V2 and V3 to perform compositing tests (if such tracks exist of course).

It's worth mentioning that since it goes through everything four times, it will take a while to finish processing, depending on the size of the project. You cannot switch to another application either or the profiling will fail. I would advise creating a brand new project with short media clips and sequences. If you truly have serious bottlenecking, this will still be apparent in the shorter sequence.

All the timing information is stored inside the Profile.csv log. Although you can view this in TextEdit, it will be difficult to read because it will not be formatted correctly. A spreadsheet application, such as MS Excel or the free NeoOffice or OpenOffice packages, is recommended.



If you are experiencing poor performance, look at the timings in this file to see where the major bottlenecks are. For instance, a slow FXScript filter could be indicative of a CPU bottleneck or an inefficient script. A slow Flop operation could be indicative of a GPU bottleneck.

Auto Profile and RT Verify appear, on the surface, to perform exactly the same task. However, it is likely that Auto Profiling actually updates your RT information whereas RT Verify merely performs the test without changing anything. This is difficult to verify without official documentation though.



Most of the functions in the Internal Tools menu will be too technical for a lot of users, and so the menu will likely remain something of a novelty. But if you are troubleshooting performance issues or developing applications and plugins for FCP, it is an invaluable source of information on the inner workings of Final Cut Pro.

The only downside is that the menu must be reactivated every time you start Final Cut Pro. If anyone knows of a way to enable it permanently through a preference file, I'd love to hear about it.

New Mac Pros, iMacs and Minis

Apple has hit us with three hardware refreshes in the same day.

Mac Mini

2.0GHz Intel Core 2 Duo	2.0GHz Intel Core 2 Duo
1GB memory	2GB memory
120GB hard drive	320GB hard drive
8x double-layer SuperDrive	8x double-layer SuperDrive
NVIDIA GeForce 9400M graphics	NVIDIA GeForce 9400M graphics
$599, shipping within 24 hours	$799, shipping within 24 hours

I'm really glad this little guy is still going strong. There were fears it would be discontinued but thankfully this has not proven to be the case.

Not the greatest specs in the world, but the GeForce 9400M is a welcome addition that should provide a decent performance boost to graphical apps.

Apple is claiming that it now uses 45% less power, making it even more viable for server-related tasks (my personal favorite use for Minis). It's worth noting that the case has not been redesigned to match the iMac, as was rumored.

iMac

20" display	24" display	24" display	24" display
2.66GHz Intel Core 2 Duo	2.66GHz Intel Core 2 Duo	2.93GHz Intel Core 2 Duo	3.06GHz Intel Core 2 Duo

$1,199.00, shipping within 24 hours	$1,499.00, shipping within 24 hours	$1,799.00	$2,199.00

Not much to say here - just a speed bump and NVIDIA graphics across the whole line. The 24" now starts at a lower pricepoint.

Mac Pro

And here's a custom configured Mac Pro with pretty much everything you'd ever need:

Two 2.93GHz Quad-Core Intel Xeon

32GB memory (8x4GB)

Mac Pro RAID Card

4 x 1TB 7200-rpm Serial ATA 3Gb/s

Xsan 2

Mini DisplayPort to Dual-Link DVI Adapter (needed for 2x 30" displays

AppleCare protection plan for Mac Pro

$19,994.00, shipping in 6-8 weeks

Processor - You might think it's just a speed bump but the Nehalem series of CPUs has a completely redesigned architecture that removes a lot of traditional bottlenecks. This will significantly improve performance (particularly memory throughput) over previous Mac Pros.

The new architecture also allows two threads per core, meaning that 16 threads can be run simultaneously on the 8 core. I had wondered if Apple would market it as a 16 core machine but they chose not to, which is probably best as it could have been misleading.

Go for the 2.93 GHz processor if you can afford it.

Memory - Apple has been generous with the memory in the 8-core model. My usual advice would be to custom configure the machine with the minimum amount of memory possible and then buy it separately from cheaper sources. Note however that the custom configurator offers a minimum of 6 GB of memory, which will be enough for the majority of people.

Hard Drives - There are four bays, each offering a 640 GB or 1 TB SATA drive at 7200 RPM. I'd advise against ordering additional drives from Apple. Instead, shop around and you will get a much better deal. They are dead simple to install.

Apple has chosen not to offer solid-state disks as an option.

Graphics - Apple is offering two cards - the NVIDIA GeForce GT 120 512MB and the ATI Radeon HD 4860 512MB. The GeForce card is available in multiples up to 4. I would not advise purchasing multiple graphics cards in anticipation of Snow Leopard, as you'd be forking out a lot of money for something that has an unknown performance benefit. You don't know that it would improve performance enough to warrant the extra cost, and you don't even know if Final Cut Studio 3 will be able to use the extra cards. You can always buy extra cards later.

The Radeon is advised for Pro App use, however, as it has much better Core Image performance and a much greater range of working color depths. It is much faster than the GeForce and no comparable NVIDIA cards are yet offered as a BTO option for the Mac Pro. Both cards come with dual-link DVI and Mini DisplayPort connectors.

Note the absence of the NVIDIA Quadro FX.

Optical Drives - Not much to say really, except no Blu-ray.

Displays - The new graphics cards have support for the DisplayPort standard so the new 24" LED Display can now be used by Mac Pros, in addition to the traditional 30" Cinema Display. It looks like the 20" will not be replaced.

Note: you must have two GeForce cards in order to connect a second 24" display, or a Mini DisplayPort to Dual-Link DVI adapter if you are connecting two 30" displays.

My advice would be to go for the 30" because it is not glossy (there unfortunately isn't a matte option for the 24") and if you want to connect more than one, your choice of graphics card is not restricted.

Other minor aspects - There is no FireWire 400 - it's FW 800 only, like the MacBook Pro. You can use FW 400 devices with a converter cable. Bluetooth is now built-in.

Conclusion

It's a product refresh - you can't expect a whole host of new features. I think the Mac Pro refresh was a decent one (and long overdue) although I would prefer more display options from Apple. The 24" should have a matte option for those that prefer it, but what I dislike the most is that you are tied to the much slower GeForce if you want to add two of these.

Additionally, no-one really knows the future of the 30". Is it wise to buy one now when there could be a possible refresh in the near future? Or is it actually better to buy one now in case Apple gives us an inferior refreshed product in the future (it has happened before)? Or should we just buy from an alternative manufacturer? That is the question.

I'm really glad they chose to release these machines while Leopard was still around. It means that when I come to buy one in the near future, I can downgrade to Leopard if problems occur with Snow Leopard. It's not best to be an early adopter of an OS if you use it for professional work, nor is it best to downgrade to an earlier OS that does not support your computer.

The price hike for the Mac Pros was less welcome but this is mainly due to the increased cost of the CPUs from Intel, so it was not unexpected. Whenever Apple gives us something, they take away something else - but I do think in this instance Apple has given more than they have taken.

Update: Apple also gave the 15" MacBook Pro a speed bump.

Blu-ray license simplification coming mid-2009

ZDnet is reporting that many of the problems preventing Blu-ray from coming to the Mac should ease in mid-2009 when new licensing comes into place.



Hopefully this new license coupled with new DisplayPort Mac Pros will encourage Apple to consider Blu-ray drives as an option for its high-end systems.

Compressor Repair 1.1.2 released

We've just released a minor update to Compressor Repair, bringing it up to version 1.1.2.

This update checks for a missing local hostname or computer name. This is a common reason for Compressor failure and can be fixed by entering a new name into the text field at the top of the Sharing dialog in System Preferences. Compressor Repair won't actually change the name but it lets you know it is missing and tell you how to change it. Why these names disappear unfortunately remains a mystery.

As always, it is completely free and is available here.

We also have several other tools and utilities in the Resources section of the site.

20" Cinema Display discontinued

MacRumors is reporting that Apple has now officially discontinued the 20" Cinema Display, not long after the 23" display was also discontinued.

Although Apple offers a newer 24" LED display, this is currently only compatible with Apple's laptop range using the new Mini-DisplayPort connectors. There is no adapter available to connect these up to a DVI-enabled machine. This means that the only current choice for Mac Pro buyers is a 30" display, which may not meet their budget or space requirements.

Never fear, the most probable reason for EOL-ing the display is to make way for new stock that will most likely ship when new Mac Pros with (Mini) DisplayPort connectors are released. That is the core market for these displays - I doubt many laptop owners have purchased one. Here's hoping they'll take a leaf out of the new 17" MBP's book and offer a matte option.

Note: Apple is no longer shipping these to resellers, but that's not to say these resellers haven't got a few 20" displays still in stock. If you call around, you might be lucky.

Compressor error: "Unable to connect to background process"

The "Unable to connect to background process" and "Unable to submit to queue" messages are common errors that unfortunately have many causes.

Before you do anything else, check that your version of Compressor is compatible with your operating system. Only the versions included with FCP 5.1.x and 6.0.x are compatible with OS X 10.5. If you have an incompatible earlier version, you will need to either upgrade Final Cut Studio or downgrade your operating system.

Try the following steps:

1. In Compressor, go to Compressor > Reset Background Processing.



2. Run Compressor Repair.

3. Trash Compressor preferences (can also be done in Compressor Repair).

4. Try these steps (use at your own risk).


Do the following if nothing else works:

5. Disable your internet / network connections.

6. Reinstall Compressor and Qmaster.

7. Perform a full erase and install of the operating system and reinstall from scratch.

Compressor Repair 1.1.1 released

We've just released Compressor Repair 1.1.1. This is a minor release that automatically enables the Qmaster startup process if the user has disabled it.

I'd also like to make a point about compatibility. Compressor Repair is designed for Compressor 3. Not all features will work with versions below this - you will receive messages stating that certain files do not exist because they were not present in earlier versions.

However, many features do work on earlier versions so it is still recommended to try it before reinstalling.

Compressor Repair is completely free and is available here. For more of our applications, visit the Resources section of the site.

Backup Options for Filmmakers

As filmmakers, we put a tremendous amount of trust in our equipment. With the rise in popularity of solid-state media, many of us are no longer shooting on tape or film. This offers many advantages but also several disadvantages. Unlike a film workflow in which many prints are made, or a tape workflow where the tapes are digitized to a hard drive and then stored safely away, filmmakers are often erasing their solid-state media and relying on a single hard drive copy to last them throughout the post production process and onto distribution/release.

Three things are guaranteed in life - death, taxes and hard drive failure. It is a fact that every hard drive will eventually fail. No-one can predict when it will happen and you may not have an opportunity to salvage the data before it does.

So it is wise to assume it will happen and have a good backup policy in case it does. Here are some of the options available for data backup.

Data Tape

While there used to be many consumer options available such as the Iomega Ditto, tape backup is now almost exclusively geared towards enterprise users. Higher-priced options have high capacities and autoload capabilities - i.e. where you insert multiple tapes at once and the system switches them automatically so you don't have to. Lower-priced options will generally require you to change the tape far more often - if you're fine with that, you can save a lot of money.

Most backup drive manufacturers are moving towards the LTO format. This is an open standard so you know that the data you backup now will work on a competitor's drive for the next 1-2 LTO generations.

One way to save money is to use an older, less advanced format. A lot of manufacturers still offer older proprietary systems for sale. These are not as advanced as the LTO options (nor as compatible with competing products) but they are much cheaper. As stated earlier, cheaper drives have lower storage capacities and are less likely to have autoloading functionality. They are also likely to have much lower data transfer rates, unlike LTO -3 and LTO-4 which can transfer data at higher speeds than a conventional hard drive.

When purchasing a drive, consider also the connector and the supplied software. Some drives use SCSI and will need a SCSI card installed inside your machine, but setup will be much easier if you opt for a Firewire version instead (not to mention allowing greater drive portability). Check if the supplied software is compatible with your operating system and if not, check if there is a compatibility update available.

Because these tapes are designed for enterprise use, they are very sturdy and have extremely low failure rates. They have normally been stress-tested by the manufacturer, and most manufacturers will offer you failure statistics on their site. You are, of course, paying for this privilege though.

Format types: LTO, VXA, SLR, DLT, DDS, AIT/SAIT, Travan, T10000
Drive manufacturers: Tandberg (formerly Exabyte), HP, Quantum, IBM, Sun StorageTek
Software: Retrospect, NetVault, CommVault, UltraBac, PresSTORE, ATempo

Pros:
* Low failure rate
* Tried and tested
* LTO-4 tapes can store terrabytes of data and access it faster than a regular hard disk

Cons:
* Expensive
* Can be complex to set up
* If you opt for a cheaper, small capacity, non-autoloading version, you will spend a lot of time changing tapes
* Overkill if you don't have much data to backup

Verdict:
Great if you're backing up a large amount of data and only plan to keep one copy.

Hard disk

The main advantage of hard disks is market penetration. You can go into almost any store and buy a disk at short notice. They are priced very low per GB, there are lots to choose from and (unless you have an old machine) you shouldn't need any new hardware or software in order to use it.

As this is primarily intended as a backup, go for an external drive. Speed is not an issue here so mounting the drive internally will offer no worthwhile performance benefit. Additionally, an external disk safely stored away will not be damaged if something happens to your machine.

It's worth mentioning that some manufacturers offer separate Mac and PC editions of their external disk drives. This is not a marketing gimmick - there is a difference! Some of the I/O controllers in certain drives (often cheaper ones) are not Mac-compatible and you will experience issues if you use one of these drives. Choose a drive enclosure with an Oxford controller where possible. Check online reviews if in doubt.

Finally, one aspect people often don't realize is that hard disks store data magnetically and must be "refreshed" every six months or so to prevent data loss, as Larry Jordan explains in this article. This must not be overlooked when considering hard disks as a backup medium.

Manufacturers: Lacie, G-Tech, Samsung, Western Digital, Seagate, Maxtor, Hitachi, Toshiba

Pros:
* Cheap
* Ubiquitous
* High capacity
* Fast transfer rate

Cons:
* Relatively high and unpredictable failure rate
* Physical bumps and bashes increase the chance of failure

Verdict:
Good for cost-effective backups but multiple backups are advised.

Solid-state flash drives

The main advantages of these drives are their small size, high potential read speed and high damage tolerance. It is likely that these will eventually replace conventional hard disks in the future and this will be a good thing, however current models have certain caveats.

The biggest of these is price. The cost per GB is considerably higher than any of the other formats on this page, and available capacities are much lower than those offered by conventional hard disks. In addition, although read speeds are fast, write speeds are considerably slower than those of conventional hard drives.

One of the most interesting aspects of flash SSDs is the way that they fail. Unlike rotating disk hard drives, SSDs do not suffer from mechanical failure but gradually wear out as you write to them. Although they have quite a high failure rate (each memory cell is limited to 100,000 writes), failure doesn't actually result in data loss. When a memory cell fails, you will be unable to write data to that cell - but you will have no problems at all reading data from it. This would be awful for a scratch disk that is written to many times but perfect for a backup in which reading is more important than writing.

However, controller chips inside the drives have been known to fail, meaning you will need to call a data recovery expert to recover the data from the disk. And there lies another problem - a lot of manufacturers uses proprietary chips that are constantly changing, making it difficult for a data recovery expert to keep up with developments. And in many drives data is difficult to recover by design, as these systems were originally developed for the military to carry sensitive information.

Efforts are being made to resolve some of these issues - such as putting two drives in a RAID 0 to improve write speeds, and balancing write operations across the entire drive to reduce the load on a single cell. Prices are going down and capacities are going up, but they will only become viable when the cost hits $1.50 per GB or less.

Manufacturers: Samsung, IBM, Intel, Corsair, SanDisk, Toshiba

Pros:
* Very fast read speeds
* Tolerant of physical abuse / damage
* More predictable failure rate than regular HDDs
* Data can still be read when drive fails

Cons:
* Very expensive per GB
* Slow write speeds
* Current drives have relatively low capacities
* Limited number of times the drive can be written to

Verdict:
One to look out for the future but limited to small backups right now.

Online Backup / Storage

There are several online backup services available. Some will give you a certain amount of space for free, requiring you to upgrade if you need more, while others offer a trial service. The advantage of one of these services is that the data is stored elsewhere and so will not be affected by theft, fire, water damage etc affecting your facility. Many of them offer software that runs on your machine and backs up your specified backup folders automatically, ensuring an up-to-date backup even if you forget.

When considering this option, you should consider security as a priority. You are handing over your files to someone else so you need an assurance that they will not end up in the wrong hands. I use Mozy to backup my laptop and all files are encrypted by default. The simplest option is to let Mozy create an encryption key for you but this is not as secure as specifying one yourself. If you do specify a custom one, beware that your data will be permanently inaccessible if you forget it.

The two biggest problems are storage space and transfer speeds. It is impractical to upload files greater than a few hundred megabytes, especially as the service takes quite a while to encrypt them before uploading. So backing up terrabytes of footage is not possible, but these services are very useful for backing up important project files. Many of them will store multiple versions of a file so you can restore to a version several days or weeks in the past. I wouldn't recommend this as your sole backup, but it would be useful as an extra cushion, especially as some companies give a small amount of space for free.

Services: Mozy, Carbonite, Dr. Backup, DropBox, iDrive

Pros:
* Simple and automatic
* Great for backing up small files

Cons:
* Not suitable for large files
* Subscription fees

Verdict:
Great as an additional backup but don't rely on this as your only option. Only suitable for small files.

Videotape

Videotape backups offer some distinct advantages over data tape backups. Firstly, unlike the LTO specification that has various revisions, video formats adhere to strict standards that rarely change. These standards tend to stick around for a long time. A brand-new DVCAM deck will play a DVCAM tape made a decade ago with no problems. LTO drives are only backwards-compatible with the last 1-2 generations which could cause problems with long-term backup.

Secondly, there is greater predictability. Tapes are rated at the hour or half-hour, making it much easier to calculate how many would be needed and how long it would take to record/play the footage, which is invaluable if you are planning to rent a deck. The downside of this, of course, is that transfer speeds are much lower than modern LTO drives.

However, when creating a videotape backup of your footage, it is important to choose the format carefully to avoid quality loss. If you shot on the Panasonic HVX-200, which shoots DVCPRO HD, it is recommended to output to DVCPRO HD tapes. If the codec you are using does not have a tape equivalent, output to a tape format that closely matches the frame size, frame rate, color sampling and approximate data rate of the original footage. Some formats like Redcode RAW 4K do not have tape equivalents and so a different backup method must be used unless you are willing to lose information.

Also make sure your tape timecode matches the timecode of the original footage, otherwise your NLE will not be able to accurately reconnect the footage to the clips on the timeline. You will spend a lot of time manually rearranging and synchronizing footage.

Formats include: MiniDV, HDV (varies per manufacturer), DVCAM, DVCPRO, DVCPRO HD, HDCAM, HDCAM SR, D1, D2, D3, D5, BetaCam, DigiBeta.
Manufacturers: Panasonic, Sony, JVC

Pros:
* Durable
* Established standards

Cons:
* Limited to real-time capture and playback
* No tape equivalent of certain formats
* Information must be captured rather than simply copied to a hard disk

Verdict:
Great for backing up established formats. Excellent for long-term backup / archival.

Blu-ray

Blu-ray discs can store around 50 GB and have a relatively low price per GB. They are compact and, if stored in a solid case, are relatively durable compared to regular hard disks. They are not as durable as tape-based alternatives, however.

Blu-ray hasn't caught on as well as everyone had hoped after the format war ended, and Apple has not yet implemented hardware or OS support for it yet. This has severely limited the availability of Blu-ray burners and software for the Mac, with the only option for data discs being Roxio Toast 10 plus the Blu-ray plugin. PC users have a lot more choice but even despite this, it has still not fully caught on in the PC market either.

Transfer rates are quite low and the format doesn't offer as much disc space as other formats. However, BD-R does have an advantage as a backup medium because it can only be written to once. Every other format can be written to or erased (some more easily than others) after a backup has occurred.

Drive Manufacturers: Sony, LaCie, LG, Pioneer
Software Manufacturers: Roxio, Sonic Solutions, Nero, Adobe Encore

Pros:
* Discs relatively cheap per GB
* Data cannot be overwritten

Cons:
* Not much support on the Mac
* Slow read/write speeds
* Low disc space compared to other offerings

Verdict:
Don't rely on it as a sole backup. Not suitable for large amounts of data.

A Game of Chance

None of the options listed above are infallible, however the point is to lower the chance of losing your data. If you have one backup, that lowers the chance of critical data loss to 0.5. Make another one and it goes down to 0.25. Backups are especially crucial if you're running a RAID because the chance of data loss increases with every drive you add (unless it is a RAID 1 of course).

So it doesn't really matter which option you choose, as any one of them will reduce that chance - some more than others of course. A mix of multiple types is the safest way to go. And when thousands or millions of dollars, plus the culmination of months or perhaps years of hard work are at stake, it helps to have a pro-active backup policy planned from the start. The fate of your movie might well depend on it.

Speculation on Mac Pro refresh

It's been more than a year since the current Mac Pros came out. Although the software to fully take advantage of them is still not here, a year is a long time and technology has moved on. As a 2009 refresh is very likely, here's some speculation on what the new machines are likely to be like.

First of all, a release to coincide with Snow Leopard is very likely, as the Mac Pros are the best-equipped machines in Apple's lineup to show off the new OS. Snow Leopard will be released (assuming no iPhone-related delays this time) in either Q1 or Q2 2009, discounting any hardware that is due to be released after this date.

CPU

I'm almost certain this will be a Xeon 5500 series "Gainestown". That will be Intel's most powerful CPU line until Beckton towards the end of the year.

Although the clock speeds are identical to the Harpertown range inside current machines, they offer significant performance boosts elsewhere. The biggest of these is an on-die memory controller (i.e. built into the CPU instead of on the motherboard). This reduces bottlenecking significantly and is something AMD's chips have had for several years. It will provide a major performance boost.

Another new technology is QuickPath Interconnect, which replaces the legacy Front-Side Bus (FSB). The FSB connects all system devices and memory to the CPU through a single interface. This is now split up, with the new memory controller handling memory and QuickPath Interconnect dealing with the other system components. You may have noticed that the caches on these CPUs are smaller than their predecessors - this is because the greater efficiency in the new architecture means data spends less time in cache memory.

There have been several optimizations to multithreading, including hyperthreading which allows two threads per core (great for Snow Leopard). Although Gainestown is limited to four cores per CPU (8 in total in a Mac Pro), Apple may market it as a 16-core machine because of the 8 extra logical cores. True 16-core machines will not be available until the end of the year when the Beckton series is released.

Memory

You're probably familiar with dual channel memory which doubles memory bandwidth. That's why you have to install Mac Pro memory modules in pairs.

The new architecture has triple channel memory! Mac Pro motherboards are expected to have three rows of four memory sockets, totaling a maximum of 96 GB (12 x 8 GB). You would be required to install chips in groups of three.

Hard Disk Options

2 TB internal hard disks are now available so it seems likely that Apple will offer these in their machines. This will allow up to 8 TB in total.

What about solid-state disks? I doubt they will be offered for the Mac Pro just yet. They're too small for media storage (unless you can afford to RAID them) and although they are a decent size for boot disks I don't think they are suitable for that purpose just yet.

I always put Western Digital Raptors (10,000 RPM) as boot disks inside my machines because they reduce boot times, load applications faster, and everything is generally more responsive as memory can be paged to and from disk a lot faster. So the fast read speeds of SSDs are welcome from me, but there are two problems. Writing is slow. The OS writes a lot of data to disk and you will notice a slowdown when multitasking or using a lot of memory at once.

The second problem is that each memory cell inside the drive has a lifetime of around 100,000 writes. You can easily exceed that in the lifetime of your computer, particularly if it is switched on constantly. Modern chips try to get around this by writing evenly to all areas of the disk in order to balance it out, but the usefulness of this will depend on the total size of the disk.

SSD technology looks very promising and these are problems that will be overcome as time goes on, but they are not ready for this kind of usage just yet in my opinion.

Graphics cards

I don't know what the stock graphics card will be but the following cards may be offered as options:

Radeon 4870 - This is a high-end card capable of accelerating H.264 and MPEG-2 encoding and decoding. ATI's drivers are traditionally much better optimized for Core Image than NVIDIA's so Final Cut Studio performance is likely to be good. Crossfire technology is available on the PC version of the card - it remains to be seen if this is something Apple will embrace. Another version, the 4870 X2 with dual GPUs, will not be available for the Mac.

It comes with DisplayPort and HDMI connectors. Apple may request a Mini DisplayPort connector instead (or in addition).

GeForce GTX 285 - This is a single-GPU card that is SLI-capable (NVIDIA's equivalent to Crossfire), should Apple choose to utilize that technology. This card does not offer DisplayPort by default so this is something likely to be requested by Apple for the Mac version.

Let's hope NVIDIA improve their Mac drivers to offer better Core Image performance.

Quadro FX 5800 - This card supports DisplayPort technologies as well as the brand-new OpenGL 3.0 specification (which the other cards do not). It's very fast but also very expensive. It is not necessarily guaranteed to make a significant difference to Pro App usage because, while it has a lot of raw power, it does not have some of the optimizations that the other cards have (e.g. H.264 hardware acceleration), and I don't know how well-optimized for Core Image they are. In addition, raw power is worthless if it is bottlenecked by other components in your system.

With the launch of Snow Leopard, Apple will be trying to sell us multiple graphics cards in our machines. I would personally wait until I have read reviews before deciding on purchasing multiple cards for Pro App usage. Also, I would have to wait until Final Cut Studio 3 came out anyway because multiple cards with FCS 2 cause problems.

Things you shouldn't hold your breath for

* eSATA - Apple has completely ignored this particular technology in the past - this time around will most likely be no different.
* FireWire S3200 / USB 3.0 - It's early days and I'm not aware of any devices currently supporting the new standards.

Conclusion

It's pure speculation but if my predictions come true, there will be a hell of a lot of new tech in the Mac Pros. Which is great because they'll be leaving a lot of legacy technologies behind - but on the other hand, new things carry a certain degree of risk.

The first-gen Mac Pros needed a couple of firmware updates to fix minor issues, and I have my own rule that says I refuse to use an operating system for professional work until at least 10.x.4. This rule will be particularly crucial for Snow Leopard which now has a 64-bit kernel, meaning every system component will need new drivers. This is fine for the hardware that ships with your machine but what about third-party capture cards, graphics tablets etc? I don't think it's going to be a huge problem but it's worth thinking about in advance.

Either way, 2009 looks pretty good for video professionals.
