un crop a video file

[stinman]

I don't know how but was wondering if a avisynth script could be wrote to uncrop a 1920 800 back to 1920 1080? I know that encoders do this to keep x264 from doing calculations on the black bars so the encode will be quicker, at least that's what I read. But if you mux this file back to a m2ts and bluray the player can't read 800 and stretches it out to 1080. Gives them big heads, Ha Ha!
Anyway hoping a something could be done with out encoding the file again.

Maybe another tool can do this but definitely not with AviSynth.

Time to channel the spirit of the late neuron2 (RIP) and ask:

Where would you get the cropped video to begin with, if not from a Blu-ray?

For that matter, your player is broken and you should look into getting one that actually respects the signalled DAR. Pretty strange that it'd support the out-of-spec 1920×800 resolution but not display it correctly.

(I'm not answering the question here because Reel.Deel has already answered it.)

You can addborders(), but Avisynth doesn't do anything at all useful without reencoding, so the answer is "no".

Have you tried enabling 'Add blank playlist for cropped video' in the bluray tab of tsmuxer? It's been years since I've used the program but vaguely remember that working for some people.
