And that's really AV2.

#496 – FFmpeg: The Incredible Technology Behind Video on the Internet

The current encoder is called AVM, and there will probably be other encoders, probably one called SVT-AV2, and those are the encoder.

The same way X264 is an encoder to H264.

The same way that X265 is an encoder for the H265 codec.

And there is a next-generation codec from the MPEG world after H.264, H.265.

Because most of the time it is a conjunct work from the ISO world and the ITU, which is the International Telecommunication Union.
