A question about audio synce when capturing AVIs...

Post by **FlyingPenguin** » Thu Jan 02, 2003 9:52 am

I'm starting to capture long videos now (over an hour) and I'm running into audio sync problems. The longer the recording, the more the audio is out of sync towards the end of the recording.

I can't understand why this is happening. I'm capturing to a RAW uncompressed AVI and I'm only dropping 7 frames in an hour, so what gives?

I'm using Vegas Video 3.0 and a Hauppauge Tech WinTV PCI video capture card.

Well I recorded a 2 hr program using the WinTV TV Application's recorder instead of Vegas Video and the sound stayed in sync, so maybe it's just Vegas Video screwing up?

Doesn't make much difference to me how I grab the AVI so if that works I'll continue using it.

video frame rate... idid some vcd's once and hosed up the frame rate had it at 23.xx instead of 29.97 whatever it is here in the states for tv's... the sound about 1/4 of the way into it was getting out of sync... check out vcdhelp.com lot of good articles over there that i'm sure will help you out.

No, I checked that. It was set for 29.97. Vegas Video has a preset for VCD compliant AVI files in the capture window, and if sets the framerate to 29.97.

I'll do another 2 hour capture with Vegas when I get a chance just to see if it was a fluke. Vega is a professional (and very expensive) video editor so I can't imagine that the capture wouldn't work right, but if need be I'll just use the capture built into the WinTV TV application. Either way it makes an AVI and then I can edit the AVI in Vegas.

With some of the DivX movies I have downloaded.. The sound is like 3 seconds ahead of the movie.. sometimes if I stop and play again it fixes it.. I've tried several different players.. Any ideas? eGo
