Hi everyone,
I'm truly sorry if this question was asked. I tried to search and found notheing.Tried also to ask it in capture forum - no answer.
Maybe anyone could help me with my problem
I'm capturing video using video bt848 chip. As compression codec i use PicVideo Mjpeg (19/20 q-ty) or huffyuv loseless codec. As a result, every hour takes about 8-15gb of space.(res=768X576). I have 2 saparate harddisks, so if i want to capture whole movie (1h40+) i have to capture it in 2 parts. As a result fps of parts always differ and it is alwas "about" 25 like 25.089,24.976 and so on,no matter what program i use. The captures got fully cynchronized. Now the problem rises: I cannot merge the parts in Virtual Dub(mod) cos they have different fps.And if i try to change fps for both parts, to , say, 25.000 audio/video is lost in sync(of course) So i don't know what to do here. The only solution i found -(i know it is stupid) is to process each part in Tmpegenc using very huge bitrate(for not to lower q-ty) like 5000kbps. REsulting files(mpeg-1) are always exatctly 25.000 fps, and then i can merge them in Dub and compress to Xvid 2passes (or other mpeg-4).
But this solution is no good, cos it takes much space,time and cpu wastle. So does anyone know better solution for my problem?
Thanks in advance for any replies.

Have a look here (http://forum.doom9.org/showthread.php?threadid=42507), if that doesnt help its probably the right place to get more help.

try using ProjectDivX!
worked several times for me where VDub has failed (without desyncing).

this tool is not so pinky with such a little difference in framerate...
