Compressor crashes when compressing audio

[Bruce]

Any other details on your system? What version of QT, Soundtrack, etc….

Try exporting your QT movie as self-contained, video only. Then export your audio separately using the “audio to .aif” command in the export window. Quit FCP, start the stand-alone Compressor app and encode the video using the same presets you used with FCP’s quicktime conversion settings. Use A.pack to encode the audio into an .ac3 file. Then you can bring both files into DVDSP as a set. Make sure both video and audio files are the same name i.e. “My Movie.m2v” and “My Movie.ac3”

If compressor does just the video without crashing then you know for sure that there’s an audio file in your timeline somewhere that’s corrupt; but maybe A.Pack will be able to blast through it without issue. Using the .ac3 file format audio will also prove to be more DVD player ‘friendly’, as the high bit rates of .aif audio tend to make some consumer DVD players choke.

Hope this helps. If you haven’t used A.Pack before and you need help with that, post back here.

[BrionD] “I haven’t a clue why my FCP HD 4.5 compressor gives an error message each time I compress the film”

It might actually help if you posted the text of the error message.

[BrionD] “Always at the about 50% completed time.”

Here’s a rule of thumb: if you always have the same error in the same place, there’s something wrong in that specific place. You may need to look at both the picture & the audio to find it, because there are times when a problem with one will cause a subtle, yet disastrous problem with the other. I’ve seen audio spikes cause glitches in the picture, for example, or a spike in the luma cause a pop in the audio.

Thanks for this….I actually ended up finding a corrupt file just at the mid point as you pointed out. Good to know for the future!

Hi,
Well 3 years later I think I have a similar problem to what you described in 2005. Yesterday I posted my problems with Compressor. Which today, I think I’ve narrowed down to having a bad audio file for at least one video I’m trying to encode.
To make a long story short,last night I did the whole de-install, & re-install, but only from the original FCP2 discs- so I’m now back to running 3.0. I submitted the same file that had stopped compressing the night before. It did the same thing again- successfully encoded the video stream, but NOT the audio. Compressor stopped working in exactly in the same place as it did the night before.

So a few questions- How does an audio file get corrupted? How did you figure out the bad file and how did you fix it?

Thanks very much

I seem to be having the exact same problem. How do I find out if an audio file is corrupt? Have you gotten any answers to this?
