Actually VfW API treats every frame as BMP (except the fact they
all have the same header)
and so M$ RLE compression scheme migrated to AVI from BMP
(technically you can also make BMP with biCompression='FFV1'
and pack data with that codec but I'm not sure that there is
any program capable doing _that_ except somebody will hack lavf :)

And in your case shaving off some bytes from BMP should make it
a perfect M$ RLE frame.
