Topaz Video Enhance AI

[rgr]

25fps->50fps conversion + image enhancement (from youtube).

First Chronos, then Artemis Low Quality -- or vice versa?

[Emulgator]

Might be source dependent.
I go vice versa, first enhance/upscale then upfps.
Takes longer, but gives... better butter.

Emulgator, what do you think about a madVR-plugin? would be cool. Found some screenshots from huh'n https://forum.doom9.org/showthread.p...09#post1967409

ATM I see VEAI and other AI algos rather as a choice of offline reconstruction algos.
Once AI gets so cheap that it an be performanced realtime, maybe.
But I think that guessing at content (to such extent and in effect repainting it) is not what a renderer should do.
A few years later my today's opinion may well be overridden by development ;-)

To continue Topaz discussion:
I can not get any enlightening out of Version 3 so far up to 3.0.4:
Slower, clumsier behaviour,
(continues rendering costly preview threads under the hood, every time I have to untick something),
the two screens are not updated in realtime but stutter around (worked in 2.6.4),
still Deinterlacing can not do what I am inclined to believe it could,
"Ugly face syndrome" still unsolved
(while calcuating Proteus on them, if faces happen to be below a certain pixel size they degrade to ugly grimaces).

I haven't even tried to get the output options tested for better parameters.
And from this month on I would have to shell out the yearly price again to be updated...
So it is 2.6.4 for me still.

Hello Topaz master
I meant the other way around, mad vir in Topaz. super-xbr is pretty good. In Topaz one can not change the upscaler? as far as i concern. Only the clean up algos. Do you know what they use?

So back to the 2.6.4. And when speaking of 264, the x264-out have some what shallow dynamics, or is it only me? kicks of from 30.

And when playing some of my old avi i get 0-255 dynamics in many players, almost HDR (in dynamics). But the very good ProRes output from 16 black. Standard yes, but dynamics is not so much Enhance.

Yes, depending on footage shadow values tended to brighten up a bit.
Could well have been a straight mismatch implemented while piping into ffmpeg x264.
Back then in a good number of cases I inserted a "lowering shadow values" gamma curve after Topaz (SmoothAdjust16),
but these days I am telling 2.6.4 to render into ProRes to lift further processing chain into 10bit precision.

super-xbr: I haven't tried seriously any other than VEAI after I got ridiculous and still watchable 450%..900% 4K upscales working, just for fun. But maybe I should someday...
