fps=25 caused ffmpeg to discard 15 of every 16 source frames, making
the final clip jump by ~2.5 minutes per frame.  The original script
had no fps filter, so all source frames were preserved.  Without it,
the setpts speed-adjust keeps every frame; the effective framerate in
the output rises proportionally (e.g. ~400fps for a full day at 10s
intervals into an 11s clip), which is fine for H.264 and all
downstream montage steps.
