MP4 to MPEG converter

DVD authoring tools, older set-top boxes and some broadcast workflows still want MPEG-2 files.

What happens to your MP4

Video is encoded to MPEG-2 and audio to MP2 in an MPEG program stream (.mpg).

Tip: For DVD authoring, set the resolution to 480p (NTSC) and frame rate to 30 or 25 fps (PAL) in Advanced.

How to convert MP4 to MPEG

  1. Drop your MP4 file on the box above, or tap it to pick one. The engine (about 31 MB) loads once per visit.
  2. The converter reads the file's streams and shows which codecs are inside.
  3. Keep the defaults, or pick a quality and resolution.
  4. Press the button, wait for the progress bar, then download your MPEG.

Prefer the command line?

This is the FFmpeg command the converter runs for a typical MP4 (h264 + aac). Paste it into a terminal with FFmpeg installed for batch jobs or files too big for a browser tab:

ffmpeg -y -i input.mp4 -map 0:v:0 -map "0:a:0?" -sn -dn -vf "scale=trunc(iw/2)*2:trunc(ih/2)*2" -c:v mpeg2video -q:v 5 -c:a mp2 -b:a 192k output.mpg

This re-encodes, so expect it to take a while on long files. Your own file may contain different codecs; the converter above detects them and adapts. For other jobs, ask the FFmpeg command helper.

Questions

Will the file be bigger?

Yes, usually 2 to 3 times at similar quality, because MPEG-2 is far less efficient than H.264.

Is my MP4 file uploaded?

No. The MP4 is read from your device by FFmpeg running as WebAssembly in the page, and the MPEG is written back to your device. No server ever receives it.

Is there a size limit for MP4 to MPEG?

We set none. The practical limit is browser memory: roughly 2 GB of output on a computer, and much less on phones.
