Andy,
Thanks so much for your quick response. I really appreciate it.
How do I find out the details of what the audio format is (whether mp3 or AAC)?
In movie inspector of a converted ProRes test — it says
Apple ProRes 422, 1920 × 1080 (1888 × 1062), Millions
16-bit Integer (Big Endian), Stereo (L R), 48.000 kHz
What will be my problems with the audio if I don’t convert? Most of the H264 are B roll so it might not be an issue.
Again, thanks for your time. Margaret
