Convert an MP4 File to AVI
MP4 to AVI converter takes a modern video and gives it back in the older AVI container, for legacy editing software, older media players, or a DVD authoring tool that expects AVI. Upload the file and download the converted copy, no software or account setup beyond signing in.
What you get:
- An MP4 file converted to AVI, original resolution and framerate kept
- Uploads up to 2 GB per file
- bulk upload of multiple files, so several MP4 files convert in one batch
- A transcript of the audio, with speaker labels, in 99 languages
- AI chat with any recording, so you can ask the converted video a question instead of watching it back
- Export the transcript as PDF, DOCX, TXT, SRT and VTT
- Free plan: 3 uploads, lifetime, each with the transcript and AI chat included
How to Convert MP4 to AVI
- Upload your MP4 file: from a computer, phone, or tablet. Files up to 2 GB are supported.
- Let it process: the file converts to AVI and the audio transcribes at the same time. Both are ready in your library once processing finishes.
- Download the AVI: open the file and download it. The transcript, speaker labels, and AI chat are attached to the same recording.
The AVI keeps the source file’s resolution and framerate, so a modern MP4 does not lose or gain detail from the switch: converting the container does not change the picture. Transcript quality follows the audio: clear narration transcribes cleanly, and a recording with background noise or overlapping speakers will have more gaps. See how we measure accuracy.

Who Converts MP4 to AVI
Video editors on legacy software need AVI because an older editing program, an older Sony Vegas build, or an older Windows Movie Maker install can read AVI more reliably than a modern MP4 codec.
DVD authoring professionals prepare footage for DVD burning and menu-creation tools that expect AVI as the source format.
Users on older computers convert modern MP4 recordings to AVI so an older media player, with better AVI codec support than MP4, can play them back.
Content archivists convert recordings to AVI for storage on legacy playback systems that were built around that format.
Presentation creators convert MP4 clips to AVI for embedding in an older PowerPoint build that plays AVI more reliably than MP4.
