user35192: I have a video 3000x1000.
I want the left part of video 1001x1000 and the right part of video 999x1000 to create a video 2000x1000. Center of original frame just dropped.
Is this possible with ffmpeg in one pass? And how?

user32358: ffmpeg -i input.mkv -filter_complex '[0:v]split[l0][r0];[l0]crop=1001:1000:0:0[l1];[r0]crop=999:1000:2001:0[r1];[l1][r1]hstack[out]' -map '[out]' ouput.mkv
