crates/engine/examples/bench_export.rs exports a 1080p23.976 H.264 + AAC
clip (made once in target/fixtures/export-bench/, with ffmpeg when it is
installed, otherwise a demo scene written by FilmCraft's own encoders)
to H.264 + AAC MP4 through the same file.exportMedia command the app runs, on the
CPU (software encoder, no GPU renderer), and prints the wall time of
each run, the median and minimum, and the export's stage times. --keep
writes the file somewhere to compare exports byte for byte; --format,
--secs and --source change the output and the input.
