Convert

MP4 to AVI

Convert an MP4 into the older AVI container, still required by some legacy software and hardware players. Since AVI does not reliably support H.264, this re-encodes the video, which takes longer than a simple remux.

Frequently asked questions

Why does this take longer than other conversions?

AVI needs a re-encoded, more widely compatible video codec rather than a simple container swap, which takes more processing time.

Will quality be affected?

There is a small quality trade-off from re-encoding, similar to any format conversion that changes the video codec.

Why would I need AVI today?

Some older editing software, embedded devices, and legacy playback systems still specifically require AVI.
