What's the audio codec?
Which version of Media Composer? Which options do you chose when exporting the ref from MC? Sounds like the audio is not correctly mixing down...
Thanks for the quick responses!
Here's some additional info from the Avid side of the problem:
We're using Media Composer 5.0
Avid Project settings are:
Sample Rate: 48kHz
Audio File Format: PCM (MXF)
Sample Bit Depth: 16 Bit
DV Audio Pattern: Unlocked Audio
Convert Sample Rate When Playing: Always
Remove Extra Filler After Punch in: Keep
Keep Dolby E Material Safe: No
Quicktime Reference Export Settings are:
Defaults: Digital Mastering
Mixdown Audio Tracks: Checked
Audio Format: WAVE (also tried AIFF with same results)
Sample Rate: Project
Sample Bit Depth: Project
When the Reference movies are created a .mov file is created as well as a .wav
If I bring the .mov into AE I get the high pitched screeching I mentioned. If I turn off
the audio for the .mov and add the .wav file to my timeline then the audio previews and renders fine.
However, I'd like to not have to go through this work-around each time I get a file from the editors,
and also need to get files from the Avid into Adobe Media Encoder where the same audio issue occurs.
Thanks again, and any help will be appreciated!
Mmmh, sounds like the bog standard settings anyone would use, so I'm ready to proclaim this a CoDec error in the Avid stuff... I really have no idea beyond that...
I have a similar issue:
AME 5.0 (downgraded after problem with VBR encoding)
I have a .mov file that is SD, progressive in ProRes 422 with 16bit 48kHz audio
If I convert to FLV from this .mov file -- OK
If I convert to FLV using a reference file which is just part of the original .mov, the audio is not encoded.
I am now re-making all my reference files as self-contained ...
What happens if the editors export self-contained QT's rather than reference QT's?
very similar to a problem i am having.
My video files are usually in one of two quicktime formats - ProRes422 or Uncompressed 10bit. I use FCP not Avid.
I have found that the ProRes files will always encode video and audio correctly. The 10bit Uncompressed files somehow manage to have the audio converted to white noise when the files are encded using Adobe Media Encoder. This problem has only appeared since the CS5 / CS5.5 upgrades, and happens on both versions of the release.
The only cure i have found has been to send all the 10bit files through Compressor first, to convert them to Prores, before running them through the AME.
