Why does QuickTime report a different resolution?

Ever wondered why QuickTime reports a completely different resolution to the one you exported at?



Welcome to the world of non-square pixels. NTSC and PAL use rectangular pixels to fill up space on the screen and save transmission bandwidth, which was more of an issue when the standards were invented. Computer monitors use square pixels and so QuickTime has to squeeze one side of the image in order to prevent it looking stretched. This is purely for display and the file is not modified.

The pixel aspect ratio of NTSC footage is 0.889 meaning 720 x 0.889 = 640 so it is displayed at 640x480. For PAL it is 1.067 so 720 x 1.067 = 768 and it is displayed at 768x576.

QuickTime also has some options for controlling how the movie is displayed. Open up your movie, go to Window > Show Movie Properties and click on the Presentation tab.

You will see an option marked "Conform aperture to:" with the following options:

Classic - Classic is identical to having the conform aperture setting switched off.




Clean - Scales the image to compensate for the pixel aspect ratio and crops it to mimic the overscan on a broadcast monitor.




Production - Scales the image to compensate for the pixel aspect ratio but does not crop the image.




Encoded Pixels - No modification is made to the footage. Note the stretching caused by non-square pixels.




This is one of the many reasons why a broadcast monitor is essential.

Preference Manager 1.0.4 released

We've just released Preference Manager 1.0.4. There's only one new feature but it's a big one.

We've completely overhauled the backup system so that backups are now stored in one compressed file instead of several folders. A lot of users want to synchronize settings between, say a work machine and a home machine. This new feature makes it much easier - just keep a copy of the file and Preference Manager on an external disk, install Preference Manager on the second machine and double-click the file. Easy.

However, these changes have caused old backups to be completely incompatible with the new version. They won't even appear in the Restore list. Don't worry though - I added a function to convert old backups to the new format. Just go to File > Convert Backups to New Format. Browse to your backup folder (default is ~/Library/Application Support/Digital Rebellion/Preference Manager/Backups), select all of your old backup folders and click the Open button to convert them to the new format. The old folders will remain on the disk in case you need them but if not, they can be safely deleted.

Preference Manager is a utility for trashing, backing up and restoring Final Cut Studio preference files, button bars, keyboard layouts, window layouts, user plugins, column layouts, track layouts and custom settings. This allows you to repair problems and copy useful settings to a second machine.

Thanks to everyone who put in feature requests and bug reports. Keep them coming.

Preference Manager 1.0.3 released

We just released Preference Manager 1.0.3. This is a quick bug fix version that repairs a rather annoying bug some of you were getting - the dreaded "The volume 'Digital Rebellion' does not exist" message.

I was aware of it and had fixed it a couple of days ago. I was planning to delay the release until early next week, as I had several features I wanted to implement over the weekend but unfortunately the number of reports I received about this bug prompted me to release this fix early.

Lots of people have been contacting me with suggestions for future versions, some of which excited me a lot because they were such great ideas. Keep it up, I appreciate it a lot.

Final Cut Pro 6.0.3 released

Can you see an update in Software Update called "Pro Applications Update 2008-01"? Well, confusingly, that's actually Final Cut Pro 6.0.3 and Compressor 3.0.3. It also includes Apple HDV Codec 1.4 and Plugin Manager 1.7.3.

Release Notes

Final Cut Pro 6.0.3

This update contains the following:

• XDCAM HD422 support
• "Project is too new or unreadable" error fixed (yay)
• Still images are now exported using their native aspect ratios
• FCP now uses the aspect ratio of the clip when stacking multiple filters in a mixed-format timeline
• When using XML import, FCP can now reconnect files that contain slashes (/) in their filenames
• You can now place generator clips in FXScript filter clip wells, although read the release notes for the caveats

If this update is not appearing for you, you must have OS X 10.4.11 or OS X 10.5.2 installed.

Compressor 3.0.3

This update contains the following:

• You can now create Apple TV movies with non-square pixel aspect ratios and there is now a Dolby AC-3 output for it as well

I was very disappointed that it did not fix any of the bugs with Compressor on Leopard.

Apple HDV Codec 1.4

This update contains the following:

• 4:2:2 support

Plugin Manager 1.7.3

This update contains the following:

• This fixes FxPlug plugins on FCP 5.1.4 that were broken my previous Plugin Manager updates

As always, never update a system mid-project. Don't update if you are not affected by the changes listed above - if it ain't broke, definitely don't fix it in the world of FCP. If you do update, make sure to make a clone of your system first.

You can get the update here as well, but you will need to have your Final Cut Studio serial number handy.

How to run Color below its minimum requirements

Color has some pretty stringent requirements. This tip will tell you how to run Color when you do not meet the minimum system requirements. Why would you want to do this? Well, maybe you have a slow machine and just want to grade a couple of simple shots or perhaps you would like to learn how to use the software before buying a new machine. Whatever the reason, here's how to do it.

Note that Apple doesn't set minimum requirements for the sake of it, and you may experience strange behavior from this tip. I wouldn't advise this for production use.

When you launch Color, it will tell you specifically what is wrong with your configuration. In this case, it is less than 128 MB of VRAM (graphics card memory).



1. Go to Applications, ctrl-click on Color and select Show Package Contents.



2. Browse to Contents/Resources.

3. Double-click minsys.plist to open it up in Property List Editor. Alternatively, you can open it in TextEdit. You might want to save a backup of this file before you change anything.



4. You will see several self-explanatory options here such as minimum QuickTime version and minimum system memory. Go to AELMinimumVRAM and change it from 128 to something lower. As I am running it on a system with 64 MB of VRAM, I will change it to 64. Just set it to something lower-than or equal-to what you currently have.



5. Save the file and open Color.

If your screen resolution is set too low, the Color interface will be tiny and unfortunately this is a side-effect of hacking the system requirements. Obviously they are there for a reason.

This tip applies to all programs in Final Cut Studio, not just Color.

Update: Our System Toolkit utility now automates this task. Just select the application name and tick Low Minimum Requirements.

Final Cut Server released

It's Tuesday, which means more goodies from Apple. Apple today released their long-awaited and much-delayed Final Cut Server software, based on the Artbox software they bought from Proximity.

Final Cut Server is an asset management system that allows you to keep track of your media. It is especially useful for facilities with a large stock footage library or companies dealing with large amounts of footage, such as news rooms.

It is also useful for smaller facilities as well. I particularly like the versioning system which tracks changes made to a file, showing you who made the change and when, and offering you a way of reverting the changes if necessary.

One of my favorite features is the event system. You can ask Final Cut Server to watch a specific attribute such as a metadata field and perform an action when that is changed, such as uploading files to a server.

The server software is Mac-only but the client software is for both PC and Mac (this probably had something to do with the delays). Here are the system requirements:

Server software
* A Mac computer with a 1.8GHz or faster PowerPC G5, Intel Core Duo, Intel Core 2 Duo, or Intel Xeon processor (Intel Core Duo, Intel Core 2 Duo, or Intel Xeon processor recommended)
* 2GB of RAM (4GB recommended)
* AGP or PCI Express Quartz Extreme graphics card (Final Cut Server is not compatible with integrated Intel graphics processors)
* Mac OS X v10.5 or later
* QuickTime 7.4.1 or later
* A CD drive for installation
* 500MB of available disk space

Client software for Mac computers
* A Mac computer with a 1.25GHz or faster PowerPC G4, PowerPC G5, Intel Core Duo, Intel Core 2 Duo, or Intel Xeon processor
* 1GB of RAM
* AGP or PCI Express Quartz Extreme graphics card (Final Cut Server is not compatible with integrated Intel graphics processors)
* A display with 1024-by-768 resolution or higher
* Mac OS X v10.4.11 or later
* QuickTime 7.4.1 or later
* Java for Mac OS X v10.4 Release 6 or later
* Final Cut Pro 6.0.2 or later for Final Cut Pro integration
* 20MB of available disk space

Client software for Windows-based computers
* A PC with Windows XP (SP2) or Vista
* 1GB of RAM
* AGP or PCI Express Quartz Extreme graphics card (Final Cut Server is not compatible with integrated Intel graphics processors)
* A display with 1024-by-768 resolution or higher
* QuickTime 7.4.1 or later
* Java SE Runtime Environment (JRE) 6 Update 4 or later
* 20MB of available disk space

Important areas to note:
* The server software is Leopard-only.
* You must fit a separate graphics card to the machine as the on-board graphics will not suffice. Also note that the G5 servers do not even have on-board graphics. This also affects any machine that you connect to it as well, which rules out MacBooks and low-end PCs.

Final Cut Server is now available for $999 (10-client version) and $1999 (Unlimited version). Interestingly, the upgrade for the 10-client version is $999 which makes it cheaper by a dollar to upgrade the 10-client version than it is to buy the unlimited version outright.

Exporting chapter markers to DVD Studio Pro

I am constantly seeing posts on Apple's support boards by people who can't get this to work. This seems to be a common problem so I'm going to give a step-by-step workflow followed by troubleshooting tips at the end.

1. In the Final Cut Pro timeline, navigate to the point you wish to place the marker, press M once to place a regular marker and then press M again to open up the Edit Marker dialog.



Make sure that you are adding the markers to the sequence itself and not to an individual clip. There are some rules though - Don't place one within 1 second of the beginning, don't place one within 1 second of the end and don't place them less than 1 second apart.

2. Click the button marked Add Chapter Marker and it will automatically insert some text into the box. Do not change this text; just click Ok.



Repeat for every marker.

3. Go to File > Export > QuickTime Movie. Do not export as QuickTime Conversion. Under the Markers drop-down, select DVD Studio Pro Markers.



Or Go to File > Export > Using Compressor. This will not display a dialog box but you will be able to see markers on the timeline in the Preview window.



4. Export the file.

5. Open up DVD Studio Pro and drag the exported file onto a track.



In the timeline, drag the edge of the horizontal scroll bar to decrease the size of the timeline and see everything at once. You should be able to see all of your chapter markers.



6. Go to Simulate and double-check that they work.

Troubleshooting

• I think most problems are caused by not knowing the restrictions on chapter markers. This is from the FCP 6 manual:
  * No chapter marker should appear closer than 1 second to the beginning or end of
  your edited sequence.
  * A chapter marker should be at least 1 second away from any other chapter marker.
  * A maximum of 99 chapter markers can be placed within a single program.
  * When you export from a sequence, only sequence markers are exported; markers in
  clips are ignored.
  * When you export a clip from the Browser, the clip's markers are exported.


• Markers within nested sequences will not be exported.


• You must select DVD Studio Pro Marker and not Chapter Marker under the QuickTime export options.


• Don't put chapter and compression markers in the same marker!


• I have had better luck with DVD Studio Pro Marker rather than All Markers in the QT export dialog.


• Be aware that if you export a QT movie with markers and then import it into Compressor, you will lose your chapter markers if you do not have Compressor 3 (included with Final Cut Studio 2).


• I have heard of people having success by trashing their preferences. We have a free utility that will automate it for you - Preference Manager.

Let me know if you can think of any more troubleshooting tips.

QuickTime 7.4.5 released

Apple just released QuickTime 7.4.5 to coincide with the release of iTunes 7.6.2 and Front Row 2.1.3. The coincidence of these releases suggests that the QT update specifically affects those applications and offers no specific benefits to Final Cut Studio. If you have a working system, DON'T install it!

On the other hand, if your system is not working, you have nothing to lose. I'd advise cloning your system beforehand though, as a non-working system could potentially be made even worse by this update.

Here are the links... use at your peril!
QuickTime 7.4.5 for Panther
QuickTime 7.4.5 for Tiger
QuickTime 7.4.5 for Leopard

I have also updated our list of QuickTime downloads.

Preference Manager 1.0.2 released

Sorry for the lack of blog updates recently; I have been working in Italy with intermittent internet access. But I'm now back and we've just released Preference Manager 1.0.2. It offers the following changes:

• Bug fix: A check is now performed for unmounted external volumes. If you set your backup location to an external disk and unmount it, the app will copy files to the default location until you plug it back in.
• Feature: Added New Folder button to Browse dialog.
• Feature: A lot of you requested it and here it is: you can now back up FCP button bars, keyboard layouts, column layouts, window layouts, track layouts, custom settings and user plugins.

("User plugins" refers to plugins residing in your ~/Library/Preferences/Final Cut Pro User Data/Plugins directory)

For those not yet aware, Preference Manager is an application that allows you to trash, backup and restore your Final Cut Studio preference files. This allows you to create a "working configuration" backup and restore to that when things go wrong. It also allows you to copy across your settings, window layouts, button bars etc, when you switch to another machine.

Preference Manager v1.0.1 released

I've been getting a lot of feedback about our new application, Preference Manager. A lot of you have really good ideas and we've just released Preference Manager 1.0.1 to take some of these suggestions into account. Here are the new features:

• Bug fix: The help link is now correct.
• Feature: You can now set a custom backup location (in Preferences). This feature was highly requested.
• Feature: If a backup exists, you now have the option of overwriting it.
• Feature: There is now a "Show in Finder" button in the Restore dialog.

Keep that feedback coming in via the bug report and feature request forms.
