QuickTime 7.4 causes issues with After Effects

After some users found problems with QuickTime 7.3, some are reporting issues with 7.4 as well.

The QT 7.3 update broke non-current versions of Final Cut Pro, causing log and capture dropouts among other things. If you were hoping the latest update fixes the problems caused by the previous patch, I'm afraid you are out of luck. You will need to downgrade to QT 7.2.

Additionally, After Effects users are reporting that version 7.4 is causing rendering issues for them. They are finding that AE will stop rendering after exactly 10 minutes with the message "After Effects error: opening movie - you do not have permission to open this file (-54)". The only solution so far is to downgrade back to QT 7.2 or 7.3.1 or wait for Adobe or Apple to issue a patch. Windows users have been reporting these issues as well, and the issue seems to affect widespread versions of AE.

There is a post on Apple's support boards that gives a way of "hacking" QuickTime back to 7.2 by installing 7.3 or 7.4 and then copying over the old 7.2 files. This is a quick and dirty way of doing it but I would not advise it. Final Cut Pro is a professional and complex application and for best results, I recommend backing up your files and performing a complete Erase and Install. This creates the most stable environment for running the software. You do not want it to fail at an important moment, particularly if you make your living from using it. Remember not to reinstall QuickTime 7.4 again afterwards!

Always remember the Golden Rule: Don't install updates on a production machine unless you have a way of quickly getting everything back to normal (such as a clone), and DEFINITELY don't install anything in the middle of a project.

Update: Some After Effects users are coping by rendering out their sequences in 10 minute segments, putting them together in Final Cut Pro and then exporting them as one movie clip. Obviously this significantly increases the total rendering time and you should make allowances for the extra time burden.

Update #2: Apparently, this issue also affects Cinema 4D and is related to an update in QuickTime's Digital Rights Management (DRM) code. Presumably this is a conflict with code designed to prevent people from copying or distributing iTunes-rented movies.

Contact form issues fixed

It was recently brought to my attention that we've been having some technical issues with the contact form lately. I was a bit surprised by this as I had only recently fixed it. It turned out that the version on the server was accidentally replaced with the old one when the site was redesigned.

I apologize for any inconvenience caused. This has now been fixed and I see no technical reason as to why it should go down again.

Macworld 2008 Keynote

Here's what Santa Steve has in store for us:

* New Airport Extreme with built-in storage, called "Time Capsule". It's designed for Time Machine, so that laptop users don't have to keep plugging in external hard drives. Backup is better automated, as users will always forget or just be lazy. Two options: 500 GB for $299 and 1 TB for $499. It will ship in February.

* New iPhone features - Maps with locations (it triangulates both cell towers and wi-fi points), webclips, customizable home screens (up to 9 separate screens), SMS multiple people at once, chapters, subtitles, and language support in video, and lyrics support in audio. This is all via the 1.1.3 firmware update that was previously leaked, and it is out today for free.

* New iPod touch features - Now features Mail, Maps, Stocks, Notes and Weather, that were previously featured exclusively on the iPhone. The update is $20 for existing users but included in the price of new units. The charge is probably partly due to potentially cannibalizing iPhone sales and partly due to accounting (they're not allowed to add major new features later on for free).

* iTunes Movie Rentals - They have Touchstone, Miramax, MGM, New Line, Lionsgate, Fox, Warner Brothers, Disney, Paramount, Universal and Sony on board. New rentals come out 30 days after DVD releases, and they will have 1000 in the library by the end of February. You have 30 days to begin watching it and you must finish it within 24 hours once you've started. You can rent in both HD and SD quality. For HD: $3.99 for older titles, $4.99 for new releases. SD titles are $1 less. There will be software updates today to enable this functionality.

* Apple TV has a brand new UI. You can rent directly from your couch, using an on-screen keyboard to type things in. You can also get podcasts and music videos. It also has .Mac and Flickr support, allowing you to view friends' photo albums. All of this software will be enabled via a free software upgrade in the next two weeks. They're also knocking $70 off the price. You also no longer require a computer in order to use it.

* They now have a deal with Fox where all new Fox Blu-ray titles will have an iTunes-compatible version on the disc designed for iPod users.

* MacBook Air - "The world's thinnest notebook". It has a 13.3" widescreen LED display (not LCD) and is 0.16 inches at its thinnest end and 0.76 at its thickest. It weighs 3lbs. Steve even whipped out an envelope on stage and fitted it inside! It's aluminum with a backlit black full-size keyboard and trackpad. The trackpad supports advanced gestures (a la the iPhone), allowing you to perform extra application functions without needing the keyboard. It also comes with an iSight camera. 80 GB hard drive as standard or you can opt for a 64 GB solid-state flash drive (much faster but considerably more expensive). 1.6 GHz Intel Core 2 Duo, with 1.8 GHz available as an option. It turns out that the processor inside is specifically made for the Air, and has been shrunk by 60% at Apple's request.

It does not come with a CD or DVD drive but there is an external one for $99 that is specifically designed for it. Apple has also created software called Remote Disc that allows you to browse other machines' optical drives via wi-fi and install software using their optical drives. You can do this with both Mac and PC machines.

It also has 5 hours of battery life when you browse the web with Wi-fi switched on. The price is $1799 and it will ship in two weeks. Pre-orders available now. It is also more eco-friendly than its predecessors, using less packaging and no mercury, arsenic, BFR or PVC.

Analysis
Ok, ok, I was wrong with my prediction of no sub-notebook. But it's good to see that Apple has dealt with the potential issues I brought up. This is a great machine for those that need something small and light without compromising power.

My favorite announcement today was iTunes movie rentals and how Apple has integrated these with the Apple TV. Steve acknowledged that the Apple TV had missed the mark somewhat, and that movies are the main driving point. I was expecting movie rentals but I was not expecting HD support as well. I was considering signing up for a Netflix account but this deal is much better. You can rent HD movies that will work on Macs, PCs, the Apple TV, iPods and iPhones for a relatively low fee. No other online rental company offers this. It is also considerably more convenient than sending and receiving discs in the mail.

I am also considering buying an Apple TV now. The device has considerably more use to me now that you can rent and watch HD movies directly from the comfort of your sofa. There is no word on whether purchased movies will be offered in HD as well, or even if they will continue to be offered at all. I will probably hold off purchasing it just yet though, as I am sure that Apple will put a DVD drive in it once a format "wins" the war. I may as well get one unit that does everything instead of 3 or 4, all with different remotes.

Steve mentioned the SDK briefly but did not really go into detail about it, which surprised me. And no 16 GB iPhone or new MacBook Pros either. I was certain they were going to be there. Maybe Apple will just do a minor update to the 'Pros without fanfare later in the year. Steve said that there were a lot of things coming in two weeks but that "there are another 50" afterwards, implying that the announcements are far from over. No new cinema displays and no mention of the Mac Mini either. Some rumor sites have been saying for years that the Mini is about to be killed off but it seems to be the one thing that no-one ever talks about. I think if Steve were to kill it, he would have something better to immediately replace it.

So, in summary, a pretty good keynote. I don't think the stock will jump as high as it did with the iPhone announcement last year but I think this will go down well with investors.

Update: Apple's site has more details on everything announced at the keynote. Also check Software Update because iTunes 7.6 and QuickTime 7.4 are already available for download (at least for me - sometimes they stagger updates across geographic locations). Do not install these on your production machine! Be especially wary of QuickTime 7.4 if you do not have an up-to-date version of Final Cut Pro.

Update 2: View the keynote video online.

Also, Blockbuster and Netflix shares dropped significantly after the keynote. Surprisingly, so did Apple's. It turns out that people were somewhat disappointed with today's keynote. The Macbook Air is a well-designed machine but the price is somewhat prohibitive, which is a shame. If you choose the solid-state drive, it takes the price to over $3000. The price per GB of solid-state memory is falling significantly every year so it would not make sense to spend that much on the solid-state version right now.

Is your Final Cut Pro sequence too dark or washed out?

This seems to be a common question. Sometimes people will create a sequence in Shake (or similar) and export to Final Cut, only to find that the image is much darker in FCP. Others have a different problem - it displays fine in FCP but appears washed out when you export it.

Final Cut Pro tends to make assumptions when it comes to gamma. If you create YUV (e.g. DV PAL, NTSC) footage, it will assume that it was created with a gamma of 2.2, which it would have been if it had been shot in a camera. Final Cut therefore lowers the gamma in order to mimic what it would look like on a broadcast monitor, resulting in a darkening of the image.

Note that the image is only dark in Final Cut Pro and if you export it, it will export with the correct gamma. However, the mistake that some people make is to brighten the image in Final Cut, leading to it being too bright upon exporting.

Applications like Shake do not make any modifications to the display of the gamma so if it looks fine in Shake, it will look fine upon exporting, no matter what Final Cut Pro is showing on the screen. This is assuming your monitor is correctly calibrated, of course.

When you import RGB elements (such as the Apple Animation codec or still images) into a YUV sequence, the opposite problem occurs. Final Cut Pro will assume they were created with a gamma of 1.8. Final Cut will then increase the gamma to 2.2 (the gamma value that FCP assumes all YUV media is created at) to compensate for this.

The image is now considered YUV, so when it plays back, Final Cut will lower the gamma again to compensate, as it does with all YUV footage. The RGB elements will be displayed on the screen at their correct gamma but when you export the sequence, the boosted gamma will be used and the exported sequence will be too bright.

The solution is to convert the files to YUV before adding them to your Final Cut Pro project. For footage, convert to Uncompressed 8-bit 4:2:2 or Uncompressed 10-bit 4:2:2 to ensure that no data will be lost in the conversion process. If the file sizes for this are too large, try a high quality lossy codec such as Apple ProRes.

For images, the easiest method is to convert them to a single-frame QuickTime file with a YUV codec such as DV NTSC. It is better to perform this task with Compressor rather than QuickTime.

Tool updates

We've updated some of our online tools to reflect the feedback we've been receiving from you.

Footage Calc
* Slightly improved loading speed of mobile version.
* Support for Uncompressed 720p and 1080p 4:2:2 at 8-bit and 10-bit
* Improved accuracy of AVID PAL 2:1 Best

My Macworld 2008 Predictions

Everyone's doing it so I thought I would jump on the bandwagon. We just got some new Mac Pros and some new Xserves so I don't think there will be any further announcements in these departments.

What I think will be announced:
* Steve is sure to show off some features of the new iPhone SDK due in February but these will most likely be non-technical, with more technical info saved for WWDC.
* New MacBook Pros. It's been a long time since the last update and Intel just released some new mobile chips.
* iTunes movie rentals and iTunes 7.6. Based on this article.
* 16 GB iPhone plus the new firmware that was previously leaked.

What I hope will be announced:
* An update to the disappointing Apple TV that will allow you to purchase songs, music and maybe even video from the iTunes store, directly from your couch. It may even combine the Mac Mini (also disappointing sales-wise) and Apple TV into one media center unit.
* New cinema displays with glass displays like the new iMac. Not sure about built-in iSight.

What I don't think will be announced:
* I'm going to go out on a limb here and say that I don't think there will be an ultraportable or a PDA. A lot of people think there will be one, but I don't. I think it would be too much of a blur between the MacBook and the iPhone / iPod Touch. Remember that with the SDK, the iPhone and Touch will essentially be PDAs so it is unlikely that there will be a separate PDA unless they can make it vastly different.

I'm writing this post on a MacBook and I can say that they can't make this thing much smaller without taking away some of the keys on the keyboard. The only way to make it really portable would be to make it a touchscreen but you would have to hold a massive screen in your hands the whole time (unless they make a stand) but then it would practically be an iPod Touch in all but size anyway. Also, flash-based storage is still very small.

* No 3G iPhone. Steve has said that 3G battery life is poor, and 3G coverage in the USA is relatively sparse.

Find out how wrong I was on January 15th at 9am.

More companies drop HD DVD

HBO announced yesterday that it will follow its parent company, Warner, in embracing Blu-ray exclusively. Warner has one more subsidiary, BBC Home Video, that has not yet announced its intentions but it is expected to follow suit.

Variety is now reporting that the two remaining studios in the HD DVD camp, Universal and Paramount, could switch sides soon as well.

They say that they can confirm that "Universal's commitment to backing HD DVD exclusively has ended" and that Paramount has an escape clause in its contract that will allow it to release films on Blu-ray after Warner embraced it exclusively. The two companies are not dropping support for the format but it is less attractive for them to remain exclusive to it.

I am certain that HD DVD will not go down without a fight, as Microsoft and Toshiba have invested a considerable amount of money into the format. Toshiba says it will remain faithful to the format but as a consumer, I would not be rushing out to buy an HD DVD player right now. If the remaining HD DVD-supporting studios choose to release their titles on both HD DVD and Blu-ray, the battle is already over. Why would you buy an HD DVD player that can play two studios' titles when you can buy a Blu-ray player that will play every company's discs? It's a no-brainer.

Update: Universal has issued a statement: "Contrary to unsubstantiated rumors from unnamed sources, Universal's current plan is to continue to support the HD DVD format". Note that they did not use the word "exclusively" or say anything about not releasing titles on Blu-ray.

New Xserves

When Apple released the new Mac Pros, they also updated their Xserve server line as well.

	New High-End Model (Early 2008)	Previous High-End Model (Late 2006)
Processor	2x Xeon 5400 quad core (8 cores) at 3 GHz	2x Xeon 5100 dual core (4 cores) at 3 GHz
Cache	12 MB per processor (24 MB total)	4 MB per processor (8 MB total)
SSE extensions	128-bit SSE4	128-bit SSE3
Frontside Bus	1.6 GHz	1.33 GHz
Memory	800 MHz DDR2	667MHz DDR2
Max hard drive space	3 TB	2.25 TB
PCI Express	2.0	1.0
Power supply	750W	650W

I can't believe that they managed to get an 8 core machine inside a 1U server. Even more amazing is that you are essentially getting double the machine with only a 100W power supply increase. This is a major improvement in performance-per-watt. The Xserve also houses an array of sensors that intelligently monitor temperature and idleness, and adjust processor and fan speeds accordingly. The Xserve power supplies also exceed 80% efficiency guidelines.

I'm not going to go into the processor improvements here, as I already did that in my Mac Pro post, but the power of having 8 cores in a server can be seen on Apple's benchmark page. It's been a while since there was an Xserve update so this new model beats its predecessor by huge amounts. On average, this machine is about 90% faster than its predecessor.

If you have ever used an Xserve, you will also welcome the news that the new model features a USB port on the front so no more delving around behind it to plug in a keyboard and mouse.

This is a great machine.

New Mac Pros

Yesterday, Apple released several updates to their Mac Pro line of professional desktop computers.

	New 8 Core High-End Model	Previous 8 Core High-End Model
Processor	2x Quad core Xeon 5400 at 3.2 GHz	2x Quad core Xeon 5300 at 3.0 GHz
Cache	12 MB per processor (24 MB total)	8 MB per processor (16 MB total)
SSE extensions	128-bit SSE4	128-bit SSE3
Frontside Bus	1.6 GHz	1.33 GHz
Memory	800 MHz DDR2	667MHz DDR2
Max. memory	32 GB	16 GB
PCI Express	2.0	1.0
Bluetooth 2.0	As standard	Extra charge
Keyboard USB hub	USB 2.0	USB 1.1

This is a big improvement over the previous 8 core model. I must admit that I wasn't a fan of the previous one because I felt that the other components were slowing down the processor. The reason for this is that the quad core model had a front side bus (FSB) speed of 1.33 GHz which means a speed of ~333 MHz per core. When the 8 core model was introduced, it kept the same FSB, meaning it only had access to ~166 MHz per core. This bottleneck caused the 8 core model to be rather underwhelming in certain situations, in some cases being outperformed by the quad core version. Overall it was a faster machine, but not as fast as it could have been.

This new version increases the processor clock speed, the FSB, there is more cache available and the memory bandwidth has increased too. If you increase one element, it will eventually bottleneck unless you increase the others, so Apple is doing the right thing by increasing them all at the same time. This thing will scream.

It's worth talking a bit about the new processor too. It is a Xeon 5400 (codename "Harpertown") with SSE4 instructions instead of SSE3 with the old model. What does this mean? Instruction sets are a list of commands that a processor can perform. They are stored in a native form which means it is much faster for the processor to execute one of these instructions to perform a task than it is to convert it from a programming language to its native form. SSE4 has several mathematical instructions that will greatly speed up video encoding and decoding, particularly when using high definition formats.

The Mac Pro now features PCI Express 2.0 which offers 500 MB/s per lane over the previous 250 MB/s. This means that the 16 lane slot for the graphics card can now transfer data at 8 GB/s over the previous 4 GB/s. Brand new graphics cards are available, including the NVIDIA Quadro FX 5600, with 1.5 GB of memory (!) and a price tag to match. The other cards are the ATI Radeon HD 2600 XT with 256 MB (the standard card) and the NVIDIA GeForce 8800 GT with 512MB. This is great news for Motion and Color users.

Apple is now offering 1 TB hard drives with 32 MB of cache for use with the Mac Pro. This allows you to have up to 4 TB of storage inside the machine, up from the previous 3 TB.

This is a really great machine. Apple has a lot of benchmarks here. The new machine seems to be a consistent 10-20% faster than the previous 8 core model. And this is just the two base models with 4 GB RAM. Upgrading to a better graphics card and more memory for example would probably widen the gap even further in Final Cut Pro 6. It's also interesting to look back nostalgically upon the Quad Power Mac G5. In its time, this machine was a speed demon but the new Mac Pro is about 100-200% faster in most tests.

The fact that Apple is releasing these models now means that there will be no significant Mac Pro announcements at Macworld next week.
