For those who’ve been kind enough to try to help with audio/video sync problems, I just had an eye-opening experience. I got my wife to check out a Vimeo clip I uploaded last night … and it’s perfectly in sync playing back on her PC. It’s wildly out of sync on my iMac. Is it possible a marginal video card can wreak such havoc? If anyone is having a similar problem and wants to check out the clip for sync playing on your machine, try https://vimeo.com/37158320 Thanks, Bill

My sync problem appears to have broadened. I loaded an .mov file from my Nikon P7000 last night. Played fine, all in sync. I trimmed it, no editing, saved it from QT 10.0 as an H.264, 5 mbits files, HD720p, and no editing. It’s badly out of sync. (time-snip) All right, this may help somebody who’s a Mac architect tell me what to do. I just played the original, unaltered file on QT, and it’s way out of sync now. Tried VLC, the same.This is beginning to sound more like a computer problem. Does anyone have any suggestions short of buying a new iMac? This is what I have, and it has never appeared to struggle with either iMovie or FCPX.

Decided to take a chance and buy FCPX. Trial was .1; this is .3. Let it update, imported files done under .1, and rerendered a 4-minute performance. If not right on, it was within a frame or two. Wouldn’t upload to Vimeo (said file was too big at 375mb?), so I put it through Compressor, ending with audio/video out of sync by more than two seconds. Tried it without Compressor, and it’s still about two seconds off, consistently from beginning to end. While the trial gave me no dialog boxes, .3 suggested I upgrade my video card, but performs identically to .1 otherwise. I’m no computer architect, but I’m fairly sure a marginal video card wouldn’t wreck the sync, particularly since I got one correct sync the first time. I’m beginning to think I’m jinxed. I sure would appreciate it if someone could help me sort this out. I began looking at a PC today and had to give myself a dopeslap.

Just did so to make sure. I’ve repeated all this so often I begin to doubt what I remember. The original media I just opened in QT is in sync. I may give it another go rendering in FCPX tomorrow to see what happens. What’s more maddening is most of what I see on YouTube is also out of sync. I found a Google discussion group where a workaround was issued to try to correct that. Seems if it’s not one thing, it’s another. Thanks for the response. I remember when a quick tug on the film guide in my CP-16 ensured the correct frame count between shutter and audio record head was all it took. Analog video from my trusty Betacam never failed. It’s a brave new world, and I’m a tired old fart.

I’m having drift problems with simple capture of video/audio from my XHA1 and a Nikon P7000. At first it was in sync (after abandoning iMovie for FCPX) and now I’m unable to get any concurrently shot video/audio to sync, in preview or after rendering. Is there no hope?

I’m having the same problem with the audio track recorded when I shot the video. I’ve captured video from my XHA1 and a Nikon P7000, and am having problems with audio/video falling out of sync. I’ve repeated capture, edit and export, and it comes and goes. At the moment, I’m unable to achieve sync with any of the files, even a 60-second clip from the P7000. This is making me crazy. I’m waiting to publish an indy music performance but can’t until I can fix the sync. I’ve read and tinkered till I’m exhausted. Any help will very much appreciated.
