I'm new to this I'm starting in Video Artifact (the program for pc not avisynth) and I'm getting this error
to export the file out.bat

Could someone help me? It seems to me that the problem is related to the audio but I'm not sure.

I don't use videoartifact, but "LWLibavVideoSource: failed to get the video track" - It means the LSmash build that the program is bundled with cannot open the video track , so you won't see anything

You can try updating the source filter because program looks abandoned since 2019. LSmash should be able to open mpeg2 in mkv, at least for avisynth directly

You can try looking for LSMASHSource.dll in the program directory and try to replace it (unzip from the archive)

I tried what you said by downloading the latest build from github and this appears for the x64 version:

and for the x86 version this:

What can I do?

The author needs to update his program, and/or modify some of the scripts

"stacked" is for legacy avisynth , newer versions of avisynth+ and their plugins use native high bit depth
