Intel ARC AV1 Hardware Encoding GPU

[tom95521]

From my limited testing AV1 software encoding is much slower than H.264/H.265. Now we are finally getting hardware encoding support for the open source AV1 codec. I hope AMD and ARM chips catch up with Intel.

Thanks, Tom. Good news.

My results from comparing encode times using the very versatile Shutter Encoder software.  I was surprised how much faster the AMD Ryzen was for AV1 encoding compared to the Mac Mini using Shutter Encoder. The H.264 encoding time is the same.

The fastest encoding was 1 min 49 sec on the Mac mini M1  (almost real time) using Wondershare Filmora 10 or 11. AV1 is apparently not supported on the Windows version of Filmora.

The new Intel AV1 GPU encoder is supposed to be 50x faster than CPU encoding.

Update: April 5
I am now getting faster than realtime encoding in the M1 version of Filmora 11.
The Sample Project is 2 min 36 sec and the AV1 encoder is finished in 2 min 15 sec (>60 fps).
When AV1 is added to PTE AV Studio I hope it works as fast.
