Video Conversion in Staxrip feels "too" slow

[Alphantom]

I have used Staxrip on a Couple of HD encodes.

I encoded a 1hr file from a bluray rip using X265 on default settings, only changing the following:

CRF 16 This took just over five hours (I am now testing 18, which is estimating around about the same encode time)

AQ 3 - Auto Variance with Bias to Dark Scenes

CRF 18

Slow Preset

All other settings unchanged.

No filters Used.

Is there a question there somewhere?
Taking 5hrs for 1hr full hd to H.265 using x265 with preset 'slow' might be even fast depending on the cpu used.

I am now using a I7-10750H CPU 2.60GHz 2,592Mhz 6 Cores.

Hevc at the "very slow" preset *is* slow. Try changing the preset to "fast" and the quality to CRF 20 - 22.
Is it a typical movie, ie. 1080p, approx 2 hours?

I am using the "Slow" preset and it is a 1 hour tv episode.

Did a quit test on my Ryzen 9 3850X using:

x265 --preset slow --input - --output-depth 10 --y4m --profile main10 --crf 18.00 --range limited --colormatrix bt709 --output "E:\Temp\8.Birds_1080p24fpsRef4-112Mbps.265"

I get ~6fps (for 8bit encoding I get ~8fps), so I assume your speed is normal for your cpu.

ON my ancient AMD FX4300, I get 1.8 fps, 1080p source, 8-bit hevc @ preset slow.
If I change it to fast, I get 6.5 fps. I'm pretty sure "fast" is the sweet spot for CPU encodes

Otherwise get a GPU and use the HW acceleration

Hevc with crf 16 is nonsense.
My 5 cents.
