The key points to avoid the problem are these:ġ. But if you want to know why, you can read more about that farther down. In this section I'll just tell you what to do so you can get back to editing. Better to set up FCP properly in the first place. I don't recommend this approach because it causes the audio to get resampled twice for no reason, which extracts a performance and quality penalty, and because it can cause issues in downstream processing. Some people solve the problem by changing the speed of the audio clips to 99.9% or 100.1% depending on which version of the problem is happening. This problem is not specific to video from DSLRs but their rise in popularity and the accompanying increase in the use of dual-system audio techniques has resulted in the problem showing up more often. More specifically if you sometimes work with NTSC frame rates (like 23.98 or 29.97) and sometimes with non-NTSC frame rates (like 25 for PAL or 30 for the Canon 5D), then you have to take some care. The Zoom H4n however is excellent and is highly recommended.) Another possibility is that some frames were dropped while capturing.īut if you are working in Final Cut Pro, a far more likely explanation is that it has not been set up exactly right. ![]() (The Zoom H4 and M-Audio Microtrack are not very good in this regard. Perhaps the clock in your audio recorder is not very accurate. There are a couple of different reasons why this can happen. ![]() It lines up nicely at one point in the timeline, but the farther away you get from that point the more out of sync the audio and video get. You carefully synchronized your audio track with your video. Thanks go to Philip Bloom and Robin Charters for illuminating discussions about this unfortunately complex topic. I have also simplified the procedure for avoiding the problem. I have learned a few things since then so now I can explain better what is going on. This post is a follow-up to my earlier post about the 99.9% speed problem that some people encounter with Final Cut Pro.
