How can I change frame rate, to join videos in one file?

[Tsubaru]

I have 3 episodes of an anime.
The first and second are 23.976, the third is 29.970.

I want to join then in one file. I'm using virtualdub and his apped system, but it only works with the same frame rate files.

I had just finish converting all of then to the right size to fit on a cd, just need to join then.

I have here the avifrate, that can change the frame rate, but the problem is that the audio loses its synch.

How can I change the frame rate of a video file, so I can append then together in virtualdub and make one file?

Hi Tsubaru,

You can change the framerate in VirtualDub. It's under the "Video" option. Then append.

There is a append option in File menu, not in Video. But append option only works for files who have same frame rate, and audio sampling.

But the problem was solved.

Using BeSweet the audio file was converted to the frame rate that I wanted, and using avifrate, I changed the frame rate of the video.
Now virtualdub is finishing the service.
