Summary of the problem or suggestion: I would like to start using video files in the AV1 format to save space and still have good quality. Can you add the AV1 as a option for output format? If you were to provide this option, I would happily donate an extra $25 and I’m sure that I’m not alone

MCEBuddy already supports AV1 encoding. You can create your own profile to do this, here’s an example:

[AV1 in MKV]
