The world called for a more efficient royalty-free codec, and AV1 is the answer. It is significantly better than VP9 at the same task, and has a significant reduction in decoding complexity, putting the complexity on the encoding side instead. Given that it is a more recent codec, support for it is still relatively small - though software decoders can handle it just fine on most devices.

You can freely adjust the Key-Frame Interval for anything but Lossless. Lossless will (and should) always produce an IDR-Frame every frame.
