DescriptionMP4 files can contain video and sound data. It is a file container that supports different multimedia content types such as multiple audio streams, subtitles, 2D and 3D image frames. MP4 is also used for streaming media services (online or digital TV). This file type supports the control of transmission speeds for media signal, as well as correcting corrupted frames. Thanks to comparatively low system requirements, MP4 is now the most popular container type for sharing media.

AVI File

File extension .AVI
CategoryVideo File
DescriptionAVI is a format intended for combining and synchronizing audio and video during playback. AVI is used by a variety of players, including KMPlayer, Windows Mediaplayer, VLC player. Uncompressed AVIs show excellent video/audio quality and do not necessitate installation of any additional codecs. However, sharing these files is very difficult because of large file size. XvidX and DivX codecs pretty much solve the problem, as they ensure effective compression that will not affect quality. Many users choose to change AVIs into other compact and versatile file types.

Our legacy DVD authoring software refuses MP4 files but accepts AVI without complaint. This converter saved me from re-encoding everything manually.

Needed AVI output for an older Premiere project that was set up years ago with AVI-only bins. Conversion was fast and the timeline imported cleanly.

We have an old projector system at the office that only reads AVI from USB. Converted our MP4 presentation files and they played without a hitch.

MP4 to AVI Converter — Frequently Asked Questions ▼

Because older hardware refuses MP4. In-car DVD/DivX head units, pre-2010 Smart TVs, embedded industrial players, and legacy editing software often accept AVI only. Converting to AVI keeps your footage playable on that hardware.
Usually yes. AVI does not officially support modern H.264 or H.265, so the converter re-encodes the picture to a DivX-compatible MPEG-4 ASP stream and the audio to MP3. This causes a small quality drop and a file size increase of around 30–50%.
Yes. AVI has shipped natively with every Windows release since Windows 3.1 (1992). Windows Media Player on Windows 7, 10, and 11 plays the output file without any extra codec install.
AVI typically uses MPEG-4 ASP (DivX/XviD), which is less efficient than H.264. To preserve similar visual quality at the same resolution, the bitrate must rise, so the file ends up 30–50% bigger.
Not natively. AVI has no subtitle track field. The workaround is an external .srt file with the same base name, which VLC and MPC-HC pick up automatically. If you need embedded subtitles, MKV or MP4 are better targets.
Use the desktop command line: TotalMovieConverter.exe C:\src_files C:\tgt_out /ConvertTo avi /ProcessRecursively walks the folder tree and converts every MP4 in one run.
Uploaded files are deleted automatically after you download the result. They are not stored, indexed, or shared. For confidential footage, convert locally with Total Movie Converter on your own machine.
 

 

Convert MP4 to AVI — Legacy Windows Container for Older Hardware

Plenty of older players, set-top boxes, in-car DVD units, and pre-2010 Smart TVs refuse to read MP4 but happily play AVI. Converting MP4 to AVI repackages your modern footage into the Microsoft Audio Video Interleave container so those devices can finally read it. Drop your .mp4 file above.

What Is MP4?

MP4 (MPEG-4 Part 14) is the 2003 ISO container that bundles H.264 or H.265 video with AAC audio. It is the default output of phones, screen recorders, OBS, YouTube downloads, and every modern non-linear editor. Native playback exists on Windows 10/11, macOS, iOS, Android, and every HTML5 browser. The format relies on relatively modern codecs that older firmware — DVD players from 2005, in-car head units from 2008, early Smart TVs — does not recognise.

What Is AVI?

AVI (Audio Video Interleave) is Microsoft's video container, released with Video for Windows in November 1992. It is one of the oldest video formats still in regular use. Internally it interleaves video and audio chunks in a RIFF structure. AVI typically carries DivX, XviD, MPEG-4 ASP, or older codecs like Cinepak. Native support exists in Windows Media Player from every Windows version since 1992, and in essentially every hardware video player ever built. The trade-off: AVI lacks modern features like subtitle tracks, chapters, and proper variable-bitrate audio.
