When you need MP4 to AVI
AVI is a long-standing video container format that old media players, home DVD and media players, certain TVs, and some editing and playback programs still expect. If a device or application does not open MP4 or shows only a black screen, converting to AVI can achieve compatibility.
Conversion re-packages and re-encodes the video and audio into a format these devices understand. The content of the clip stays the same - the container and encoding change.
What changes after conversion
You get the same clip in AVI format. Since the video is re-encoded during conversion, the result depends on the source: a low-quality file will not give a sharp picture, and fast-action scenes and fine details may shift slightly. AVI usually takes more space than MP4 at comparable quality.
Some modern MP4 features do not carry over to AVI: multiple audio tracks, embedded subtitles, and chapters may not be preserved. For a simple clip with audio this usually does not matter.
When this is especially useful
- Playing video on an old TV or home player that does not open MP4.
- Loading a clip into a program that only accepts AVI.
- Preparing a file for a device or piece of equipment stuck on old formats.
- Compatibility with an old computer or editor without MP4 support.
Common tasks and search situations
- convert MP4 to AVI for an old TV;
- open video on a home player that does not read MP4;
- prepare a clip for a program that only accepts AVI;
- convert video for an old computer;
- make AVI for a device that does not understand MP4;
- re-encode a clip in a familiar old format.
What to check before converting
- Find out what format and encoding your device or program actually expects.
- Assess the quality of the source MP4: conversion will not make the picture better than the original.
- Keep in mind that AVI is usually larger than MP4.
- Check the finished file on the actual device it is being made for.
Format and conversion limits
AVI is an old container, and some MP4 capabilities do not carry over: additional audio tracks, embedded subtitles, and chapters may be lost. Re-encoding depends on the source: quality will not improve, and the size will usually increase. If a specific player expects particular encoding, a generic AVI may not work perfectly - check the result on the target device.

If the device works better with other containers, see MP4 to MKV or MP4 to MOV. When you need the reverse conversion to a modern format, AVI to MP4 is the right choice.
What is MP4 to AVI conversion used for
Video for an old TV

File for an old program
Video is prepared in AVI for an application or editor that only accepts this container.
Compatibility with an old computer
On a device without MP4 support, a clip in AVI plays in the familiar media player.
Recording for a home player
Video is converted to AVI for equipment stuck on old playback formats.
Tips for converting MP4 to AVI
Check device requirements
Different players expect different encoding. Before converting in bulk, check one file on the target device to confirm compatibility.
Do not expect a better picture
Quality is limited by the source MP4. Converting to AVI changes the format but does not make video sharper than the original.
Allow for larger size
AVI usually takes more space than MP4. Check that the file will fit on the target storage or device.
