Why Convert AV1 to MP4?

Device Compatibility

AV1 is the newest video codec with excellent compression, but hardware decoding support is limited to devices from 2022+. Many phones, smart TVs, game consoles, and streaming devices can't play AV1. Converting to MP4 (H.264) ensures playback on every device.

Software Compatibility

Some video editors, media players, and streaming platforms don't yet support AV1 input. MP4 with H.264 is universally accepted.

Sharing

MP4 is accepted by all social media platforms, messaging apps, and email services. AV1 may not be recognized.

Note: Converting from AV1 to H.264 MP4 will increase file size since H.264 is less efficient. The tradeoff is universal compatibility.
