Good observation. Not only is the size identical to the original, but
also the codec. ;-) What Jim erroneously did was to use the command
line options "-c copy -c:a pcm_s24le" *after* "-vcodec ffv1" - which
implies that the video is copied.

Jim, you need to reorder those options, or drop "-c copy", to achieve
what you desired.
