Free online VGM to MP4 converter

A VGM file stores game sound-chip data, not a finished video, so platforms and editors that require MP4 need it rendered with audio and visuals. Converting it lets you share or play a game-music recording in a standard video format.

What the VGM format is

VGM (Video Game Music) files record sound-chip commands used to reproduce music and effects from game hardware. Emulators and VGM logging tools create them; you may also encounter them in game-music archives. A VGM file is not a conventional audio recording, so a compatible player or converter must render its commands as sound.

What the MP4 format is

MP4 is a multimedia container commonly used for video encoded with H.264 and audio encoded with AAC. It is widely accepted by video editors, phones, and sharing platforms. Since VGM contains no picture, the MP4 must include a visual track, such as a still image or generated graphic, alongside the rendered music.

How to convert VGM to MP4

Online on 101convert.com

1. Open the VGM-to-MP4 converter on 101convert.com and upload the VGM file. You can add several files for batch conversion; the page shows the per-file size limit.
2. Before converting, set what the video shows using the converter’s available setting.
3. Start conversion, then download the resulting MP4 file.

Offline with desktop software

Free workflow on Windows: Use foobar2000 with the Game Emu Player input component to render the VGM as WAV, then use FFmpeg to make the MP4. In foobar2000, open the VGM, select the track, choose Convert → …, and select WAV as the output format. Create a still image such as cover.png, then run this FFmpeg command in the folder containing the image and rendered audio:

ffmpeg -loop 1 -framerate 30 -i cover.png -i music.wav -c:v libx264 -tune stillimage -pix_fmt yuv420p -c:a aac -b:a 192k -shortest output.mp4

FFmpeg runs on Windows, macOS, and Linux. The command repeats the still image for the audio’s duration and encodes a broadly compatible H.264/AAC MP4.

Commercial alternative: In Adobe Premiere Pro, import a WAV rendered from VGM and an image, place both on the timeline, and extend the image to cover the audio. Choose File → Export → Media, set the format to H.264, and export the MP4. Premiere Pro does not use VGM as a normal audio source, so render it to WAV first.

Quality and compatibility

VGM stores chip commands rather than a fixed waveform, so the rendered sound can vary with the player’s chip emulation. MP4 conversion does not recover original game visuals; you must supply or generate them. AAC encoding is lossy, while the WAV intermediate avoids adding an extra lossy audio encode before MP4 export. Check the rendered duration if the VGM playback includes loops.
