Earlier in the week I committed some fairly-well tested extensive improvements that went into this release.
One area significantly impacted is all of Export. When resampling is requested (unconditional in some instances, e.g., MPEG and Other), then it performs a locked audio output by computing a correction ratio in the resampling rate to produce the expected number of audio samples. This is quite important in fixing the a/v sync drift that occurs in long projects. It is based upon a process I came up with while helping Dan Sawyer with his commercial DVD project. There is the possibility for some sync problems because the ratio is computed and applied over the entire project (or scene if splitting). In other words, there is no checkpointing. For example, I could have continually repeated the process over some period of video frames, say 1 or 2 seconds worth. But my tests did not show this necessary.
Oh yeah, Export/DV PIpe is now more appropriatley named Export/Other. Finally, the FX UI got some love in the area of usability improvement, and the Trim UI got some love in the area of bug fixes.
