I recorded a party with my dslr but the sound does not sync with the person talking. How can I fix this video ?

That's weird, what camera?
I have had this problem before but it was with a mini DV camera. I had to manually slide the audio over about 30 frames for it to sink up with the video. Then the problem was that in between shots, all of the "white noise" in the audio was gone for about 1 second. So, I had to copy areas of the video where no one was talking and paste into those areas to fix it. You can do this is any video editing software, i.e., Premiere, FCP, etc. The best way to do it is look at the waveforms of the audio and look for a visual cue in the video, such as a balloon popping, or a person yelling, clinking a glass, etc. Your waveform, will have a spike at that area, allowing you to slide it over and match it up. It's kind of like what a clapper board does but it will be somewhere in the scene instead of at the beginning.

What he said. I went to film school back when they were still using film and an external tape recorder. It's that audio spike with the clapboard you're looking and listening for. When I got my first video camera (Hi8), I said to heck with the clapboard, it's all on one tape; there should be no problems with synching? Guess what? When I digitized the footage into Premiere, the audio didn't sync. Since then, I have ALWAYS used a clapboard. In lieu of a clapboard, what R. Benson said about looking for an audio spike is EXACTLY what I had to do, and what you will have to do. While it may sound like a pain, this is how film and audio have been sync'ed at least since the "Jazz Singer". And, honestly, it's still the best method, because the human eyes, ears, and hands working in conjuction has yet to be surpassed by any technology. Afterall, isn't it for the human experience we make films, not the computer? ...Kurzweil not withstanding.

I have watched movies, home made videos, U Tube videos and everything was in sync. The mouth moved in sync with the video. I have done nothing different to my computer and now all video's are out of sync with the mouth and songs sung!!! I hope someone has an easy solution to this problem--it's driving me crazy!! :)
