Problem with framerates

[Razorblade2000]

I have got a problem, everytime I record sth. using PowerVCRII I get MPEG2 files with 29.97 fps.
First of all, it would be nice if PowerVCRII accepted my new profiles, my registry changes or the changes in his configuration files, but he doesn`t. It simply ignores them. I tried every way to record with 25fps, but it didn't work. Now I recorded sth. with 29.97 fps and recognized that is totally out of sync when I demux the mpa stream and encode the video and audio file using Gordian Knot/Real Producer/Virtualdub. After changing the videoframerate of the bad avi file in Virtualdub to 25, it was in perfect sync. Now I have got problems to get good encodes in real because I can't change the framerate like I could do it in Vdub... Is there any solution to this? (e.g. changing the framerate in the MPEG header?)

hi,

i think u could solve your problem by adding the line : assumefps(25,true) in the avs file , this will slowdown the video to 25fps.

make some test and post the result.

bye.

Why don't you use vdub_sync together with an MJPEG codec, as you're going to reencode it anyways?

Ok, it's a bit harder to setup (not really, you just have to play around some hours to fiddle everything out ;) ).

You won't get problems with async sound, you're in control what happens etc.

Check out the capture-forum, there's plenty of information available .)

I tried and got unbeliveable many problems with my tv card driver (even with the btwincap). At the moment Vdub wont even start capture mode, he freezes...

I'll give it a try! Thanks (Is there a list of avisynth commands anywhere?)

v1.06 is very well documented at Videotools (http://www.videotools.net) (Edwin van Eggelen's site) and most new functions in 1.07x/2.0x are described in this thread (http://forum.doom9.org/showthread.php?s=&threadid=30014)
