Some x265 presets aren't working as intended

[nikkoaki]

Description of problem or question:
Tried to encode a video with x256. All profiles between Ultra Fast and Medium seem to work ok. Switching to Slow or a slower profile will result in a very low quality video.



Steps to reproduce the problem (If Applicable):
Just select the slow profile, multi-pass encoding, constant frame rate and a low fixed bit rate.



HandBrake version (e.g., 1.0.0):
1.7.3 compiled with the FDK flag



Operating system and version (e.g., Ubuntu 16.04 LTS, macOS 10.13 High Sierra, Windows 10 Creators Update):
Win 10 22H2 x64

[nikkoaki]

Just tried the provided pre compiled hb.dll and the problem persists.

[s55]

Not unsurprising when you are trying to encode at 300kbit. When you enable more features, it is normal that it can require more bit-rate as the encoder can be retaining more detail.

The preset affects Speed, Quality and Filesize. All 3 are affected but your artificially capping bitrate which is causing you problems.

[nikkoaki]

The 300kbps was on purpose to see which encoder one can retain more detail at the same extreme low bit rate (trying different presets too).
I always thought that choosing a slower preset would give better results at the expense of encoding speed, at a fixed bit rate.
x265 is the only one that behaves like this. AV1 gives ever so slightly a better result with a much slower preset and x264 is basically the same.

[Rodeo314]

Either way, x265 is not developed by HandBrake, so there's pretty much nothing we can do about it.

[s55]

x264/AV1 are not really relevant. They are different encoders. Nothing states that x265 must behave the same.

Not all features that the slower presents turn on area bout compression efficiency.

Thank you for the explanation

[nikkoaki]

Was doing another couple of tests and noticed that i wasn't getting bad quality videos this time at the same resolution/bit rate/encoder.
Tried the old video sample again and yep, i'm now getting nice quality on the slower presets. It's actually the "Turbo analysis pass" that seems to bork the image quality on the slower presets, or actually, having it turned off creates low quality videos.
This is messing with my mind again because i thought it was supposed to be the opposite. Thought that turning on that option would give faster encoding speeds at the expense of a bit of quality in some scenarios.

[mduell]

The turbo first pass just skips a bunch of options that are slow and typically don't make a difference.

For trying something with extremely low bitrates, I'd leave it off, you want all the encode options applied to the first pass.

That's what i thought, but turning it off will produce a lower quality video. The quality improves a lot if i turn it on.

[mduell]

Can you post both encoding logs so we can see whats happening?

[nikkoaki]

Sure

Oh, it's missing on rate control by a lot given how short the content is and how high the QPs are. The encode looks worse because it's a third smaller.

For non-stillimage HD video in the 300 kbps range, you may be better off targeting like RF 50 rather than a specific bitrate.
