Keeping externally recorded audio synced up with long video interviews? Drifting Audio Challenge!
I did a LOT of long interviews and recorded audio on a field recorder. when i sync up with hand clap all is well for first few minutes but then it starts to drift by the middle and end of interview. I assume i used different audio rates or something (i am a rookie, i admit). has anyone come out with some software that mirrors the two in some way? i will only use 30-90 seconds out of each 20-40 minute interview. so i just was wondering if anyone had any ideas, solutions, suggestions as it’s taking so so much time to slide the audio left and right when i find the areas i want to use and have good audio.
Thoughts?
Thanks much!

Up to a recent post (https://forums.creativecow.net/thread/200/896802#896802), can be some issues when making long audio recordings.

There is also the possibility that your video is running at the wrong frame rate (resulting in faster or slower playback). Right-click on a clip in the timeline, then go Properties > Format and check the vid rate.
Is it the same you recorded your material in?

[Josiah Hall] “I’d also check the sample rate of the audio from the recorder too.
I encountered that a couple years ago where the video and sequence settings to project I was involved in were all okay, but we found the sound recordist captured our audio in the wrong sample rate for the video, so consequently you’d try to sync it up then wonder why it would go out of sync half-way through, haha.”
The sample rate shouldn’t cause any problem.
FC can manage whatever sample rate you drop in. For example, no problems with tracks from CDs (44.1Khz).
So far there are two problems that has been causing audio drifts on FC, the one mentioned on my post, and an old FC’s bug documented on this article:
