Compressor vs FCP for QT with 5.1 Surround

[Andrew Hecker]

Add to that, I have changed the Easy Setup settings to 24p and it still imports stills as 29.97. It ignores its own settings. The real bad part about this is that no developer will ever be able to fix this.

I have arrived at 99.9% exactly from this aspect which you have pointed out. And getting perfect lip sync. Somehow, despite the FCP timeline showing 24 fps, I have this feeling that the video runs on 23.98 fps, and the audio takes the 24 fps normal route. To match, the audio has to be stretched like this: 23.976 divided by 24 into 100. This comes to 99.9% and the audio matches beep to beep.
I have a feeling that either this is a bug in FCP or maybe I have put some selection in FCP on, which goes for preserving the camera metadata, ignoring the timeline settings. Have not been able to figure out yet. Any clue to solve this?

@Andrew: It’s not necessarily true that you have to export the video and sound together. If you export the video and the sound tracks separately in 24 fps (after matching the sound with 99.9% stretch) they will match in a non-fcp platform (for example in soundscape or protools and also in all cinema platforms like DCP and DI platforms where sound and picture need to be separate for cinema projection). The picture in cinema platform will run in 24 fps, despite the FCP’s anomaly of running it in 23.98 fps and hence the audio goes perfect lip sync with 24 fps video out. I had just completed my feature film and figured this out with lots of sleepless nights.
If you are not going into cinema platform and will stay in video platform only, you can do the following: give the output of the video track and the audio tracks separately in 23.98 fps. Now they’ll match after you import them back in FCP timeline.

Did you check the frame rate that FCP has stamped on the audio file? Changing the speed doesn’t fix the feature/ bug but it corrects the error.

If you want to fix it and have it reliable for all frame rates in FCP then follow the details in Matt Lyon’s tutorial.

[Subrata Sen]

Yes, the FCP even after stretching shows 24 fps. Even the video shows 24 fps.

Use AIFF insted of WAVE. should work.
