pourquoi un préréglage rapide et pas lent pour qtgmc ??
Hi.
New user here.
Trying to use Chronos Fast v3, and I seem to be stuck on a screen that is telling me ‘Preparing AI Model’
‘The AI Model is being loaded - this may take a few minutes’.
No Joke - 15 minutes so far and no obvious things happening.
What is not right here?
Paid version.
Windows 10 (latest)
11th gen Intel i7-11700k @ 3.6GHz with 32Gb RAM
NVidia GEForce RTX 3060 Graphics Card
Any suggestions will be wonderful please as I do not get why things are running so slowly here
possible firewall issue blocking the download of the models ?
Does anyone know if “Auto-detection model parameters” in VEAI 2.6.4 does the same thing as “Auto”/“Relative to Auto” in 3.0.x?
no it’s not. the “auto” detection in VEAI 2.6.4 is the same as proteus/estimate in 3.0. it’s a one frame analyse, when the Auto of 3.0 does an analyse / change on Each frame of the video.
Nope.
It turned out to be the default Slomo setting of NaN and manually setting this to 100% started things off. I had previously ignored this as I stupidly assumed it meant ‘Not Applicable’.
However, I now have a more serious problem that makes no sense - the converted files are running too fast! If I go from the source at 2:00:59:12 and run it to 24fps in Cronos, it end up 18 seconds too short compared to the original file, and if I run it to 23.976fps it ends up 8 seconds too short.
Why is this happening - and more importantly how do I stop it & get an output file the same length as the source file was?
Anyone get their hands on the new Nvidia 4090 card? What kind of performance gains did you see?

Looking at that graph it seems it would be better to just build a second PC in a Dan A4 H20 and just let it go 24/7 in a room or outside if you own a home.
Stuff like this is why I’m really considering shoving a A770 to go along with my RTX 3070ti, but I really hope that Video Enhance AI gets Intel XMX’d like Photo AI does to help sped things up a lot. It’s actually crazy that the $350 Intel GPU is a little faster than a 3090/3080 which still go for $600+ on Ebay, and you get good HW AV1 encoding.
There’s also a new Nvidia driver today, with CPU related optimizations. Time to do another run or two of 2.6.4 and 3.0-7b/8b for a before and after?
Edit: Did some tests.
No differences for me on my 3080Ti.
Driver 512.X / 5.17.X
Topaz video enhance AI
2.6.4 RTX 3080ti- (83% pwr limit, UV+RAM OC, 3600MHZ DDR4 + 5700X OC)
0.15-0.16spf
3.0-6b:
0.14-0.15s spf
Both with ‘MP4’ output, 4mbps for 3.x, CRF 17 for 2.6.4
Driver 5.22.25:
2.6.4:
0.15spf (holding here longer/less fluctuation?)
3.0-06b:
0.14-0.16spf (basically, no difference) = 21s for 5s preview
3.0-08b: same thing, 21s for 5s preview
Thanks for posting a driver update does jack shit. Now I don’t have to update drivers.
Ok so I went and bought an MSI RTX 4090, installed the latest studio driver, and compared to my old RTX 3080 the results were…not impressive.
Upscaling a 1080p to 4K video my seconds per frame dropped from 0.46 to 0.35 using Gaia HQ, however Artemis HQ was the same and Proteus 2 actually did worse, increasing from 0.46 spf to 0.51
Doubling a 720p video to 1440p again Gaia improved from 0.23 spf to 0.17. However Artemis HQ only got better by 0.01 spf and Proteus 2 got worst by that amount.
Doubling a 480p video to 960p all models performed better, however it was only by 0.01-0.02 spf.
In conclusion, if you want to buy a graphics card just for Topaz VEAI save your money and get a cheaper model.

To me, this is already a very telling test in confirming that still TVAI Beta does not exploit the Tensor Cores of RTX GPUs well!
Welcome to the “upgrading didn’t speed up VEAI that much” club. At least the new 3 beta reduces GPU pwr/consumption by a good bit to bring nice speedups on some mobile RTX GPUs. Now for the question of, does stacking a A770 + 3070/3080 have a speedup greater than a 4090 at the cost of a 3090?

No surprise there, a 3090 runs at 47% average utilisation on my machine for 1080p → 4K. Can barely tell the difference between a 3070. All in all I think RTX cards have a lot of untapped power when it comes to Video Enhance. I have not tried the v3 beta but I heard usage is better there. How many upscales can you run with a 4090 without any noticeable slowdown? With Gaia on a 3090 at that resolution it’s about 2.
You mean how does it perform running parallel jobs? Is that even possible with 2.6.4 as I haven’t tried out the beta yet.
you can do it with 2.6.4 by launching the software several time like 2 or 3 times.
for the beta/EA, it’s done in preference, it’s an option to turn on, and fortunatly it does it in one app.

Using my 4090 I tried upscaling two 1080p videos to 4K with Gaia at once. When ran separately the first had an estimated time of 1:15 and the second one 1:42. When I ran them both at the same time the times jumped to 1:45 and 2:20.
I repeated the test upscaling two 720p videos to 1440p. When ran in parallel the estimated times jumped even higher, from 2:50 and 1:40 to 3:42 and 2:13.
Finally one last time upscaling 480p videos to 960p. This time the jumps were far less, from 1:35 and 0:42 to 1:54 and 0:51. Adding a third video caused the times to jump even more to 2:05 and 1:01.
So while running parallel jobs does slow things down it still saves you time compared to running them in sequential order.
ask @Imo, he’s the one i know that used a lot 2.6.4 version separatly at the same time.
i have a s*** card with 4Gb ram, so never did this.
did you tested the 4090 with the 3.0 beta/EA ? do you have better processing time than 2.6.4 ?
anyway, from what i read/know, speed improvement has not be done yet on the 3.x
3.x has a parallel processing included.
anyway, between the drivers and very recent 4090 release and the softwares not optimised at all for this card, it’s looking pretty normal that it’s not running as it could be expected by “owning” the best card on the market actually (for “normal” user).
certainly at some point, the optimisation for such a card will be done but not on 2.6.4 but on the 3.x. ask the dev (suraj) what he think about the 4090 Rtx and the future of VEAI for such a card (as a suggestion 
)!
Can you please check with nvidia-smi.exe in what power state your 4090 while upscaling 720p?
On my 3090 it is always P3, but when I resize frame and make it 5-6% larger, card sometimes comes in P0 state (and sometimes not) and it speeds up process.
As a result in Proteus FT mode pure 1280x720 shows 0.16-0.17s for frame and same video resized to 1344x756 may show 0.14-0.15s
