Hi, thanks for the report. Can reproduce the crash on master and 3.0.0 beta

if one of them is an mp4

Hard to say if this is correct. I can even reproduce with one .mkv and .mov file

@PratikPB2123 you're right, it looks like it's related to the stream inside, not the container. So 2 mkv files, one with MP4 (divx) and the other with MP2 streams, don't trigger the bug. But as soon as one stream is H.264, it crashes.

I can't reproduce this issue. Can you provide movie files that cause crash?

sure thing: 0001-0005.mkv
(just exported 5 frames of the default scene with the default settings at the lowest possible quality so it would be small, yet importing that at the same time as another video triggers the crash for me)

Thanks for sample file. This happens because some files have audio track present and some don't. Nothing to do with codec fortunately.

I see, checking here and that sounds right (pardon the pun)
