There’s little detail to be had about what’s contained in Pro Applications Update 2009-01. Release notes say that the update addresses general compatibility issues, while improving overall stability, and addressing a number of other minor issues.
Release notes for the individual updates contain more detail. Final Cut Pro 7.0.1 fixes an issue where the video-editing app could quit when using the AJA Io HD and playing mixed format sequences. The update also fixes an issue where a clip would run backward for a short time when using the new Change Speed dialog to add both Curve from Start and Curve to End speed ramps on the same clip with the setting for Ripple Sequence unchecked. Other Final Cut Pro fixes include one where a Desktop Cinema Display Preview would tear the bottom of an image when using a Cinema Display with a MacBook Pro, another involving the Close Gap command, and color shifts for video material at 2048×1080 and 2048×1556 frame sizes. The update adds an .aif extension to audio files created using the Voice Over Tool
The Motion 4.0.1 update increases quality and precision when rendering a scene with an animated focal point, improves rending performance for certain flattened text objects, and improves third-party FXPlug support. The update also fixes an issue which caused Compressor jobs to not complete when they were tasked with processing older Motion projects.
Speaking of Compressor, the release notes for the 3.5.1 update note that the release fixes the ability to inspect surround sound jobs and addresses a transcoding issue with automatic resizing for videos recorded on the iPhone 3GS and iPod nano. Compressor 3.5.1 also fixes issues involving transcodes between Apple ProRes codecs and the redrawing of file names in the Inspector when replacing audio files.
The release notes for Soundtrack Pro 3.0.1 are pretty thin—all the update appears to correct is an issue with the Get Info window for Soundtrack Pro. Color 1.5.1, meanwhile, fixes issues involving live footage showing a luminance mismatch, the difference in aspect ratio between a clip aspect ration and a frame being display as gray instead of black, and Color FX nodes created in the Color FX Room not lading when a project was saved and re-opened.
