audio and video out of synch

[kenw]

I recently inputted video from a Canon HV20 into my computer via firewire. When I play the video using EMC 8 the audio and video are not in synch, i.e. there is a lag between both.

 

If this can't be corrected, I don't see how one can edit the video. Have I done something wrong?

 

Secondly, I cannot get the individual frames to show in the time line. All I can see is the very first frame.

 

Can anyone out there provide some help?

 

Thanks to all for guidance

Number 2: That's the way it is; scroll along the timeline or look at the preview.

 

Number 1: There are a lot of causes and cures. If the audio is off the entire file by the same amount, go to Media Manager, navigate to the file and right click to select extract audio. Save it as a wav file. Go back to Video Wave and add the video. Use show/hide tracks to show native audio and then use the speaker icon to mute it. Add the wav file you created to any of the other audio tracks and move it so that the video and audio match up. It is pretty easy to do so but you may want to look at the appropriate demo video (audio) here

In addition to what Steve said, a known culprit for poor audio sync is a badly fragmented hard drive - always run defragment before you render

To what format did you capture? Many posters seem to have less audio/video sync problems capturing to DV avi and in ssegments of 10 minutes or so. Also some of the posters complain of the problem after creating the DVD not after capturing

It's MPEG and it's 12+ minutes long.

 

Not sure about a good match up by cutting and pasting audio. I've tried that before without success. haven't tried the defrag route but will.

12 minutes is not too long, I would try a capture to avi to see if the problems disappear. Editing avi files also seems to
