The bigger challenge is that reality is killing 8K video because of the limits of human perception. I challenge you to find video content that looks better encoded at native 8K than downscaled to 4K at the same bitrate when viewed at enough distances that the edges of the screen are at a minimally acceptable viewing angle. No one in Hollywood is doing any post production in 8K. Heck, most visual effects are still being done in 2K for cost/speed reasons, and because 2K looks just fine if there's some motion blur and/or grain.

And with everyone working from home, even experimenting in 8K is nigh impossible. There literally aren't any monitors that are 8K, HDR, and have DisplayPort. Monitoring 8K HDR means using a (WAY too big for a desk) TV and a $3K AJA Kona 5 with experimental and finicky HDMI 2.1 firmware.

With libvpx-vp9 v1.9.0 auto-alt-ref only works in 2pass. was this changed or was this always the case?

Yes (sadly).

[edit]
At --cpu-used=4 using VBR, it works also in one-pass mode in some cases. But at other speeds or in CRF, it works in 2-pass only.

See this code.

Thanks for clarifying. But I'm confused. Why was it changed? Was it not working correctly before?

Sounds like meaningful development wrapped up around January? I wonder if many of the contributors moved on to SVT-AV1.

Kind of funny that per-frame QP control took that long to implement.

There are still lot of commits in libvpx after 1.13: https://chromium.googlesource.com/webm/libvpx/+log

Also for classic AV1 libaom: https://aomedia.googlesource.com/aom/+log

Much more than on SVT-AV1 https://gitlab.com/AOMediaCodec/SVT-...ref_type=HEADS

Yeah, no doubt that work continues apace on AV1 encoders, open source and proprietary.

2024-01-18 v1.14.0 "Venetian Duck"

This release drops support for old C compilers, such as Visual Studio 2012
and older, that disallow mixing variable declarations and statements (a C99
feature). It adds support for run-time CPU feature detection for Arm
platforms, as well as support for darwin23 (macOS 14).

This release is ABI incompatible with the previous release.

Various new features for rate control library for real-time: SVC parallel
encoding, loopfilter level, support for frame dropping, and screen content.

New callback function send_tpl_gop_stats for vp9 external rate control
library, which can be used to transmit TPL stats for a group of pictures. A
public header vpx_tpl.h is added for the definition of TPL stats used in
this callback.

libwebm is upgraded to libwebm-1.0.0.29-9-g1930e3c.

- Enhancement:
Improvements on Neon optimizations: VoD: 12-35% speed up for bitdepth 8,
68%-151% speed up for high bitdepth.
Improvements on AVX2 and SSE optimizations.
Improvements on LSX optimizations for LoongArch.
42-49% speedup on speed 0 VoD encoding.
Android API level predicates.
