I have four MPV files. They're four quarters of a football game. Three are 704x576 and mux together perfectly. One is 352x576 and won't co-operate.
How can I scale it vertically to match everything else (which it already does on playback anyway, presumably due to an aspect ratio flag or something) while keeping it compatible with the other three?

That one has to be re-encoded to match if you want to append them
If it's interlaced, you'd need to double rate deinterlace, scale, re-interlace
Encode using the same settings as the other files, then append
Since the smaller clip only requires resizing horizontally it doesn't need to be deinterlaced before scaling.
Another possibility is remux the videos into TS files, then just append the TS files. Resolution changes are allowed in TS files. Not all players will handle the changes properly though.
Probably my bad actually, I got it wrong in the OP.
However, none are my files originally and I'm not sure what settings were used, so I'm not sure how to go about the re-encoding step. I'd rather not re-encode the other three if that's avoidable.
