SVT-HEVC encoder have some interesting features compare
with the existing HEVC encoder.
- Multidimensional parallelism
a). Picture-based parallelism
b). Segment-based parallelism (scales over many CPU cores)
c). Will support tile-based parallelism soon
- Human Visual System(HVS)-optimized classification for
a). Data-efficient processing
b). Computationally efficient partitioning and mode decision
c). Higher coding efficiency
- Resource adaptive scalability
a). Speed up factor vs HM 16 about 70 times (4K/60fps content,
SVT-HEVC enable subjective quality mode with preset setting
with M0(highest quality))
b). Outperformance the x265 encoder in CQP mode
- Real-time encoding of up to 1x 8Kp60/10-bit streams on the
Platinum 8180 with preset M11/subjective quality mode
- Real-time encoding of up to 2x 8Kp50/10-bit streams on the
Platinum 8180 with preset M12/subjective quality mode
- Real-time encoding of up to 4x 4Kp60/10-bit streams on the
Gold 6148 with preset M12/subjective quality mode
- Real-time encoding of up to 6x 4Kp60/10-bit streams on the
Platinum 8180 with preset M12/subjective quality mode
To me, this does not sound much better than the informationwith the existing HEVC encoder.

libturing provided and we rejected the patch.
I have no objections but a better reasoning may be desirable,
especially regarding the subjective quality of the output streams.
