Support and limits

What this MP4 MIDI converter reads

01

Input

Choose one MP4, MOV, or M4A file up to 100 MB and 5 minutes. The file must contain an audio track that your browser can decode.

02

Audio only

The video picture is ignored. The converter analyzes the soundtrack; it does not read hands, keys, captions, or notation shown in the frames.

03

Output

You get one standard .mid file containing detected note pitch, timing, duration, and velocity on one track.

04

Codec support

MP4 and MOV are containers, so two files with the same extension can use different audio codecs. If this browser cannot decode one, export its soundtrack as M4A, MP3, or WAV and try again.

FAQ

Convert MP4 to MIDI without hiding the limits

How do I convert MP4 to MIDI online?

Choose the MP4 above, wait while this browser decodes its audio track and detects notes, then select Download MIDI. The file is processed on your device rather than uploaded to this site.

Can this MP4 MIDI converter read the video picture?

No. It converts the soundtrack only. It cannot infer notes from moving hands, piano keys, captions, or sheet music shown in the video.

Why can one MP4 convert while another cannot?

MP4 is a container, not one audio codec. Conversion works only when this browser can decode the file's audio track. Export unsupported audio as M4A, MP3, or WAV before trying again.

Can I convert MOV to MIDI on this page?

Yes when the MOV contains a browser-decodable audio track. Select the file the same way as an MP4. The converter analyzes audio, ignores video frames, and produces one .mid file.

Is convert MP4 to MIDI processing private?

The selected file is decoded and analyzed in this browser. This page does not send it to a conversion server, and there is no login or saved history.
