Remotion and Mediabunny

On September 1st 2025, we announced that we are combining our efforts and are helping Mediabunny become the definitive multimedia library for the web!

As a result, we will be slowing phasing out @remotion/media-parser and @remotion/webcodecs and deprecate it when Mediabunny has reached the same capabilities.

Should I use Mediabunny or Media Parser?​

As of February 2026, we recommend that you now migrate to Mediabunny.
Media Parser is now deprecated.

See the snippets in this documentation section to help you migrate.

Differences in features​

Some features are available in Media Parser but not (yet) in Mediabunny, and vice versa.
Here are some notable ones:

Features exclusive to Media Parser:

  • .m3u8 and .avi container support
  • Foreign file probing

Features exclusive to Mediabunny:

  • .ogg, .adts container support
  • Compression
  • Media Player
  • Video creation
  • Live recording and streaming
  • Tree shaking

Mediabunny is generally faster.
Media Parser has higher-level APIs ("extractFrames()") while Mediabunny's API is lower-level.
Mediabunny has a more permissive license (see below).

If one of these characteristics is important for you, let this influence your choice.

Mediabunny is an independent project by Vanilagy.
Remotion is a Gold Sponsor of Mediabunny.

Reporting bugs​

If you can pin down an issue to the Mediabunny library directly, then report an issue under Mediabunny's repo.
If an issue also concerns Remotion usage described in our docs, you can file it within the Remotion repo.

License​

Remotion (the framework), @remotion/media-parser and @remotion/webcodecs continue to use the Remotion License. If you are using Remotion and are not eligible for the Free License, you continue to require a Company License.

Mediabunny has a more permissive MPL 2.0 license.
If you are a company and you are only interested in the multimedia library, you don't need a Company License to use Mediabunny - it is truly open source!

What happens with remotion.dev/convert?​

As of October 20th 2025, remotion.dev/convert is now updated to use Mediabunny!
