To try against?

I only know of the mplayer archive, see https://github.com/anthwlock/untrunc/issues/74#issuecomment-729581683. If you know the camera model, maybe using a search engine will lead you to some raw samples.

@anthwlock I actually have screengrabbe by screenpresso software, I was able to make audio work by -s parameter with uncorrupted video from the same source at the end. Video, no go for now. It was broken by Windows suspension during recording.

Maybe related to this? https://github.com/anthwlock/untrunc/issues/95

Maybe related to this?

95

Seems likely! But I haven't looked into that issue yet, so if you find something, lmk.

Also a exiftool good.mp4 might show some further correlation between your files and those from #95. But please post further infos in that issue, not here!
