Extract multiple video tracks from one video container.

[Russai]

I have video with video 2 tracks i can switch between then in VLC trough menu Video > Video Track.

How do i save each track as separate file without re-encoding anything, and later also how do i build it back into one MP4 file?

I tried VirtualDub and AviDemux however i see no option to access second video track.

Use clever Ffmpeg-GUI.
Load your movie, click main, click extract audiostream, choose your stream and click extract.

That GUI does not allow to select second track only first one is selectable and extracting.

P.S. video is 24FPS not 45FPS as it reports.

Managed to extract from command line.

ffmpeg -i input.avi -map 0:1 -vcodec copy vid1.mp4
ffmpeg -i input.avi -map 0:2 -vcodec copy vid2.mp4

Sorry, thought you were trying to extract 2 audio streams.
Btw: it is unusual that a video container has 2 video streams.
