PBX 4.19. Nvidia poor encoding quality

[davidcd13]

With the new version 4.19. The quality of NVidia encoding is really lower. The video is pixelated with a loss of detail. Could you put a quality setting option or go back to the old setting?

Cordially

 

[Tom Speirs]

Could you please post a log with the encoding going on. Thanks.

[Tom Speirs]

Oh wait. I can see. okay. Im working on it.

[Tom Speirs]

Sorry about that. I am still testing for the best encoding parameters but it should be greatly improved in 4.20. Available in a minute.

Too bad the version wasn't released on Monday 4/20...

 

[Tom Speirs]

Its okay, don't worry, ill smoke some tomorrow instead

I just updated to 4.23.
But I think the quality is more poor than with 4.19 itself
The 4k video is capture with NVidia driver itself and converted by FFMPEG

See for example previous screenshot (was 350mb video)

 

New captured video (30mb)

EDIT : Doing a compare with 4.19, I see also a decrease of quality. Didn't noticed that yesterday

 

[Tom Speirs]

I have not got any real 4k tables to test with but am using 4k 60fps.

Please try 4.24 and let me know results. I get that quality is worse but am trying to reduce file size now.

Many thanks.

[Mike_da_Spike]

It's still pixelated with 4.24

This table is not 4k. I can try it with a 4k too, but a normal table (fullhd) should not be pixelated as well

[Tom Speirs]

Looks much better though.

Im working on it.

lol. Depends how you look at it

Compared to version 4.23 it is a bit better, but compared to 4.18 ...

I hear ya. Still though a 30 second video should not be 300mb right?

[Tom Speirs]

Could you get me the table please so I can test? The last video too. Thanks.

@Tom SpeirsAll looks much better in 4.25 again, only the size is big again. Even if I put it on the lowest quality, it is a big file.

[davidcd13]

Thank you, it's perfect with the new version. (4.26)

Should be resolved in 4.26.

Will check today. Thanks for all the work Tom !

Great work @Tom Speirs!
The hevc codec looks good and also reduces the file from 320mb - 86Mb on the 'medium' quality (21).
(I noticed other videos that reduces from 100mb -> 8mb) 
I'm a bit experimenting with the values to make the best videos (for myself) that won't loose too much quality.
And I can reduce my videos from 45sec to 20 sec. Don't think I notice the difference.

Again. Thanks Tom for your hard work this weekend. It looks like you wanted an easy release, but finally took you way more time, but the end results is really amazing !
My videos directory can be reduced a lot (only the4 visual pinball directory is already 60gb)

Thanks for the feedback buddy. Washout it there is little point.
