Hello All, I would be more than grateful to know the best way of finding out (info) what bit rate Compression has been used in any QT.mov or MP4 files audio. QT Apple i only tells you the codec used AAC and 48 or 44.1 etc. Not the bit rate used to compress example 128. 320. 96 etc Cheers Don H

Are you talking about the audio? The bit rate for the video is in the movie inspector. You should never be using compressed audio in a video file for production.

Hi Don,

Not free (1 dollar) but this will give you all the video and audio file information you need, and much more:

itunes.apple.com/app/mediainfo/id510620098

This is a bit simpler but free, though I don't know if it's supported in the newest Mac OS:
