benwaggoner If the codec will always be so slow to encode on x86 CPUs, then this encoder will be exclusively for large companies that are capable of acquiring a HW encoder.
AV1 it is a medal from two sides:
1. free and high quality 2. the need to purchase special HW encoders.
Therefore, what is the point of the community to develop it in of quality improvement.
AV1 in its current form (x86), is simply a way of advertising and popularization, nothing more.
p.s. AV1 - "free" (need buy HW) codec for only youtube...

rav1e is a reasonably fast encoder, it can do several fps and will get faster with time.

Also youtube won't be the only ones adopting this. Facebook, bbc iplayer, netflix etc and many others will be adopting this.

It's not completely set in stone, but I really believe H.264/AVC might be the last codec easily encodable in pure x86/x64. lntel and AMD have agreed on some extensions to make H.265/HEVC and AV1 not suck quite as much, but the obvious direction is in GPU or fixed-function encoding.

I think that is the reason H.264/AVC ditched some complicated features whether they can be implemented by hardware decoder or not. In some extensions, heavy taxing on cpu loading from software encoding perspective is quite possible.

How do I beat a pulsating noise?
I need to save/delete it across the entire sample (using the AOM settings).
