COMMON QUESTIONS
MP4 to MIDI FAQs
Can I convert MP4 to MIDI for free?
Yes, converting is free in your browser. New visitors get 1 free download, and verified users get an extra free download. To keep downloading afterward, you can buy a permanent credit pack (no subscription).
How do I convert an MP4 video file to MIDI?
Upload your MP4 file to our converter. The tool reads the video's audio track, transcribes the notes with AI, and lets you preview, edit, and download the MIDI file. It's a fully online, browser-based process — no software to install.
Does MP4 to MIDI convert the video or just the audio?
Only the audio track. An MP4 is a container that holds both a video stream and an audio stream. Our converter analyzes the audio track and transcribes it into MIDI notes; the video frames are ignored during conversion.
How accurate is the MP4 to MIDI conversion?
Accuracy depends on the clarity of the audio track in your MP4. Solo instruments, clear vocals, and clean melodies transcribe the best. Our AI model (Spotify Basic Pitch) detects note onsets, pitch, and velocity with high precision. Use the built-in piano roll editor to fine-tune the result.
Is my MP4 file uploaded to a server during conversion?
No. All processing happens locally in your browser using a lightweight AI model. Your video and audio never leave your device, making it completely private and secure.
What are the duration limits?
The converter accepts MP4 files with audio up to 5 minutes. For longer videos, trim the clip or extract a short audio section first.
Can I edit the MIDI notes after conversion?
Yes. The built-in piano roll editor lets you move, resize, join, or delete notes with undo/redo support. You can also adjust sensitivity, minimum note length, and pitch bends to fine-tune the transcription.
What is the difference between MP4 and MIDI?
MP4 is a video container format that stores recorded audio and video. MIDI is a set of musical instructions — which notes were played, when, and how hard. Converting MP4 to MIDI transcribes the notes from the audio track so you can edit, transpose, or play them back through any virtual instrument.
What audio types work best with MP4 to MIDI conversion?
The converter includes presets for Piano, Voice, Guitar, Bass, Solo (monophonic), and Full Song (polyphonic). Choose the preset that matches the audio in your MP4 for the best transcription results.
Which file formats are supported for video to MIDI conversion?
In addition to MP4, the converter accepts common video and audio formats including WebM, MOV, M4V, MP3, WAV, M4A, FLAC, OGG, and more. Upload any supported file and the audio track will be transcribed to MIDI.

Yes. All conversion happens in your browser, so there are no server costs — which means the tool stays completely free, with no account, no watermarks, and no hidden fees. You can convert as many MP4 files as you like, as long as each is within the duration limit.
