I would like a transform video filter that can 'shift' the image horizontally by a number of pixels. The part that is pushed off the screen would be 'wrapped' to join with the other side. I would use this to set the 'home' camera position of a VR360 video file.
E.g.
Say we have a video that is 8x2 pixels and we want to shift it horizontally
Original video
ABCDEFGH
12345678
Filtered video with 4 pixel shift
EFGHABCD
56781234
Filtered video with 2 pixel shift
GHABCDEF
78123456
Thanks

Filter intergration into Avidemux is extremely slow. Also, this is a pretty niche request.
I would suggest considering ffmpeg. The link below explains one method.
