Hitting record used to capture from wherever the reel stood — at the
end, the auto-stop fired a beat later and saved one second of the
final frame. Recording now rewinds to the top and rolls the whole
reel. And the container asks for MP4 (H.264) first, the format every
phone and platform plays, keeping WebM only where the browser cannot
mux it; the extension follows the container.
