Hi my friend, thank you! :D

The upscale phase for video is really slow but with super pc like yours should definitely be fast. Did you check this options?

For example:

* AI backend option. Did you selected the right gpu? you should have 2 gpus, one integrated in cpu and the Nvidia 4090

* VRAM limiter option. Did you select the correct amount of VRAM for your gpu? For the 4090 you should select 24 GB

* CPU number optio. Did you select the correct amount of cpus? For example your cpu has 24 cores.

Also, for the new 10.0 version that will come in few weeks there are a LOT of bugfix and improvements for video upscaling in particular :)

Hello and thank you for the fast answer. Yes, I did as you said.

AI backend I have only one, the 4090 to chose from.

With the speed now it will still take at least one, I think two days to finish.

I maybe still use something wrong, because as you say, it should run a bit faster in my machine. Also I have 64 GB RAM, if this could be a brake of the process.

Hi my friend! Thank you :D

What is the resolution of the video you are processing?

If you open the Windows Task Manager can you check that your gpu is being used?

In my testing lately I have found that Windows 11 has slowdowns in reading and writing files, and as you can imagine this impacts QualityScaler's speed a lot. Do you have windows 10 or 11?

Thank you for your feedbacks :)

The resolution is 1424x944.

Taskmanager shows my GPU is in nearly 100% use. And I use Windows 11. So maybe Win11 is the reason then. :(

Absolutely super manageable resolution from your 4090; at this point I really think it's Windows 11 which is not yet fully optimized.

If you can try there is ReviOS, an optimized version of Windows 10 or 11. free of Defender, Cortana and that kind of bloatware, updated ISO every month with patches :)

I am too much of a noob for non Windows... Shame on me, I know... :(

Do not worry my friend, some update will fix Windows 11 :D

Thank you for your help. And I will do more experiments with your great creation. :)

Hello to both of you! I love this tool. Especially upscaling very old pictures or short recordings. Unfortunately I experience similar habits upscaling mp4 vids. Using multiple computer setups (win10) while Version 9 maxed out CPU and GPU the newest Version 10 takes up 14 perc max.

Hi my friend,

and thank you :)

Version 9.0 had a bug that allowed excessive cpu usage.

I'm working on improving QualityScaler more and more on the speed issue, but basically I can't do much for now because the 3 AIs of QualityScaler offer very good quality but have a very very complex and slow architecture.

For long videos I would recommend RealScaler, another upscale app of mine that uses Real-ESRGAN as the AI. In particular "RealESR_generalv3_x4" offers much faster speed (about 4 times faster than BSRGAN) at the expense of lower upscale quality.

Thank you :)
