The VideoLAN Forums

I have an MP4 or MKV file that consists of multiple video tracks, with each track having a different resolution, frame rate and aspect ratio. Currently when i play this file in VLC, it opens several windows to display each track's video i.e. one display window per track. I am trying to avoid the time factor it takes to re-encode the individual video track to have the same resolution, frame rate and aspect ratio.

Is there a way VLC can play these video tracks in an ordered sequence back-to-back, in a single window, whereby Track 2 begins once Track 1 has ended, and so on and so forth?

You need to use VLC nightly build to play only one of them.

To play back to back and select the right one, automatically, I doubt you can, so far. We can select the audio track, but not the video one.
