Hello everyone!

First I clean head in my VCR then I connect [spam] and grab video using DScaler because other programs give me bad sync with audio or something doesn't worked. For compression I use HuffYUV 2.2.0 codec. Video length is 4h 10m, file size 115 GB, frame size 720x576, FPS 25. Now I would like to compress that to Xvid or x264, but I have problem with “jumpy” frames like this one (http://img713.imageshack.us/img713/4230/0000ns.png). It always takes 2 frames and there is too many of them, which becomes annoying to watch. Can I do something to fix this? Or if is not possible can I remove automatically broken frames?

My second problem is filters. I download lots of filter for VirtualDub and I’m not sure which one I have to use because I don’t know what they are doing. I found some info about filters but my English is not enough to understand everything what I read, is not my mother language. By the way sorry for my English :) I really try to find answers but finally I give up and I wrote here. Please help.

That looks like loss of vertical synchronisation to me, which is probably the reason other capturing programs complained. For certainty you need to determine the source, because it could be caused by the VCR or the capturing.

If you get the same problem when outputing the VCR to a working TV set, the problem is there. It could still be dirty heads, and/or damaged tape, and/or incorrectly set tracking/vertical synchronisation.

Otherwise, the problem is with the video adapter and/or the capturing. Look for frame rate, tracking and/or vertical synchronisation settings to adjust.

If nothing helps, try to compare results with another VCR, another capturing cable, another capture card or computer etc. Do all this very carefully and compare results after each step. Although it is possible to remove or to some extent repair damaged frames, it's even more work than this. ;)

Cheers,
