music for a video?
« on: October 12, 2009, 08:48:37 PM »
should I record at 48kHz or 44.1 (like I would normally for a CD)?

Well, if your video will be burned to dvd then you would be better off using 48 because the dvd audio track is a 48.0 kHz pcm file. There is much debate about quantization problems when converting sample rates from 44.1 to 48.0 but it may be only minor details. (Splitting hairs? I don't know.) Many modern video cameras have the audio set at 48 kHz by default.

However, I have imported/edited audio at 44.1 and then burned to dvd (with video) and it sounded fine. If you have the means, 48.0 is higher quality than 44.1.

I thought there was something to do with timecode and synching to a video

any thoughts on converting from 44.1 to 48... (can t even be done)... I suppose I could import one into another session at the other rate?

44.1 to 48?  Some say you should always avoid up-sampling if you can. The computer must add extra samples where they don't exist. The process causes guessing or interpolating to occur. I believe that if it guesses a wrong amplitude value, at some places, it can result in slight distortion or anomalies or something (or at least inaccuracies.)

But then again, it may be so minor that it will go unnoticed. Try it and see.
