encoding to cfr (120 fps)
This is the most widely compatible option. For this you'll need [TIVTC and avi_tc]. Start by creating a decimated avi with timecodes.txt, but skip the muxing. Then open tc-gui's tc2cfr tab and add your files or use this command line:

tc2cfr 120000/1001 c:\video\video.avi c:\video\timecodes.txt c:\video\video-120.avi

Then mux with your audio. This works because tc2cfr creates an avi with drop frames filling in the extra space with drop frames to create a smooth 120fps avi.

By following above direction, I was able to make 120 fps avi. But the problem is that the audio is out of syn!! The length of video is 24:85:45 / 119.880fps, while the length of audio is 24:19:83. I have tried every option in virtualdubmod, "sync to audio", etc. I serched the forum, and the best suggestion so far was to change the framerate, but even that didn't help. According to above directions, it seems like all i need to do is mux 120fps avi with audio, but what tools should i use that would make avi and audio sync together? or do i need to edit audio as well? Thanks in advance!

Is it out by a constant amount? Like, always 10 seconds off the entire video? Then you have to set audio delay in vdubmod. If it steadily grows, it is a framerate issue, but that shouldn't happen if the original is in sync (at least in my tests it didn't).

Also, run that 24:85:45 by me again :p
