MKV with VFR to AVI with CFR

[PeaceMasta]

Hi there. I've been working myself through a couple of guides and stuff about this problem (http://www.avisynth.org/VariableFrameRateVideo), but I've come to no solution either because I wasn't able to follow the guide or because none of the guides really treated my problem/idea of solving the problem:

I have a video with VFR MPEG4 (DivX 5.xx) and AAC MP4A content in a MKV-container. The problem is that my StandAlone-DivX player does neither support MKV nor AAC. So first I just changed the container of the video to AVI (VirtualDub[Mod]), encoded the sound to AC3 (Graphedit via ffdshow) and muxed them together (VirtualDub[Mod]). Then I had the problem that when i tried to play that video on my SAP, the sound went out of sync. After a little research i discovered, that those animated videos are often encoded in VFR to safe space. Well either that avi-container(crap) does not support VFR or my SAP does not. Now I have read a couple of guides about changing MPEG2-hybrid stuff to CFR avi stuff and so, but all of these guides either needed a re-encode or those guides treated videos where the source was MPEG2 or where the result was wanted to be VFR whereas the source was CFR.

I would love to know if its possible to just duplicate the frames that need to be duplicated to make the VFR to a CFR without reencoding the video.

Thanks for any kind of help.

//edit: I also tried to follow this thread :

But when i use the script

and encode it to something like huffyuv, all i get is a green screen.

You are trying to pack a AMD64 CPU into an old socket A motherboard, to allow using your old 2 MB video card with modern software ? Good luck .....

Ok Thanks. Thatone works quite well. With reencoding it :/
