Audio Formats for Final Cut
Hello people, Vic here. Just a quick question about audio formats. I am not a video mixer, I am providing a mix down of a live gig for a live DVD. I am not doing the video editing. What is the best format to give to the video editor? I can provide all types, but need to know if in the final processing the audio is dithered, or is any dithering done when the DVD is pressed by the factory. I don’t want more than one stage of dithering and therefore do I provide 32 bit/fp @ 48kHz. Is there a problem with large wavs (or aiff) and should I provide AC3 or another compressed format. It is a 43 minute long set, so the audio file is very large. Thanks in advance. Vic

32 bit files are not supported in Final Cut. The files would be best as 24 bit Wav or aif @ 48khz. This is the standard sample rate for DVD and all digital video and PCM is the only thing for Final Cut.
Final Cut can import poly wavs if the source is multi channel.

Thanks for the reply – 24bit 48k it is – still a little dithering involved, but I’m guessing the noise floor will still be quite low

well, the end result will be 16 bit anyways, as the DVD specs allow no 24 bit, so why not make that?
(and if the end product is already mixed, there will be no issues with your ‘noise floor’…)Bouke

Always ask the People that NEED the file.
But we would want:
16 bit
48k
stereo (concert)
.aif (or .wav)Chris Tompkins

I pointed out that you are not supposed to dither audio more than once, so if I dithered down to 16bit/44.1k – and then the audio was further processed, it could add noise. The editor wasn’t sure if there was any further dithering within Final Cut, or when the finished DVD files are sent off to the pressing plant. Just wanted to be safe. Thanks for your help guys

Erm – 44.1kHz – CD format sample rate
-
48Khz 16 bits is DVD video standard…

Thanks – this is what I need – as I have been told CD format is fine.

Kick the one who told you.
Of course it can be converted to 48Khz, but any Mp3 can be used as well, and there are a lot of people who will never hear the difference.(Keep in mind that lots of video people have one or two computers, lots of harddisks and other gear with fans right on their desktop, and have no decent audio monitoring…)
