Progs to tell u the EXACT:3 100ths of a sec length of a vid?

[christaltips]

hi all, ive got audio sync problems with these 2 joined MPEGs I extracted from 2 VCDs using VCDGear. I joined the two MPEGs using "Easy Video Joiner", which btw was a stupid decision, because now VD tells me there's an improper join when i demuxed the audio. ill remember never to use that prog again. I've deleted the original VCDs, so i can't rejoin the videos. Goldwave informs me that the audio track is summit like "2:26:42.401", but unfortunately i cant find out exactly how long the video file is. WMP and other progs tell me its "2:26:42", so i warped the audio to this length, but i still get sync problems. It must be 100ths of a second out, so i need a program which will tell me the length to this degree of accuracy?

thanks all

Can you even tell if something is out by a 100th of a second ?

Vdub can do this for you, but it is not sufficient to just make both streams the same length. You should use the visual/audible sync method. Find a point, in Vdub, at the end of the video where something noticeable happens (like a gunshot or something) find the time that that occured and write it down. Then find that same point in the audio stream with goldwave or audacity. Compress or expand the audio stream so that that event occurs at the same time as it happened in the video stream. This works for movies that start in sync but go out of sync. Obviousely variations of offsetting the audio and compressing/expanding the audio will solve almost all sync problems. Just make sure that various points in the movie sync with respect to audio and video. It is a long and dirty method but it works.
