just double checked, this is not the case in written pal8 nut files

Then check an odd-width nut file like the one below. And FFmpeg
doesn't
care about specs when using "-vcodec copy". The stride will be the one
of the original data, whether it's 2, 4 or some other amount of bytes.
The stride will be *aligned* to 2, 4 or some other amount of bytes.

Try "ffmpeg -i 8bpp_129.avi -vcodec rawvideo 8bpp_129.nut" with the file
below. It will have a stride aligned to 4 bytes like the original AVI
file, and per the Microsoft specification, since it doesn't "-vcodec
copy" won't touch the video data.

I mean "ffmpeg -i 8bpp_129.avi -vcodec copy 8bpp_129.nut" of course.

The stride will be 132 bytes, divisible by 4, rather than 129 bytes.
