Re: [Avid-L2] Converting audio frame rates

 

I work with every broadcast timebase all the time within FCP 7, and have done for several years - and have happily mixed-and-matched audio mixes between them all. Never have I seen FCP speed up or slow down the audio as you describe.

When there's a timebase mis-match, FCP generally wants to render the audio (assumedly to re-write the embedded timecode?) which I've always found annoying, but I've never had a mix change duration.
Maybe I've just been lucky.

Why does he need to slow it down?  2 seconds of audio at 23.98 is still two seconds. Two seconds of audio at 25 fps is still 2 seconds. 

Not in FCP. FCP, believe it or not, doesn´t care about the Audio Sample rate, treating audio as video, and if your sequence settings doesn´t match audio Frame rate it slow/speed it without asking.

Tell your friend to use Sound Devices Wave Agent (free) to change framerate metadata and he will be fine.

It´s also important that the "Easy Setup" matches the sequence framerate.

He will need to create a new project because once Imported, FCP "remembers" that the original file had different framerate and will slow it no matter what.

Hope this help.
