What is your GPU and driver version?

GPU driver has not changed since the outage and emergency update, when it was all working well. Intel 31.0.191.2121 3/12/2023

What's the GPU?

Style Transfer works. Smart Masking works. The Sharp models in Upscale work. Colorization doesn't work.

Resetting Vegas made no difference. Revo uninstall of everything and reinstall of VEGAS_Pro_20.0.0.403_DLV_DE-EN-FR-ES-BR_230504_07-19_FAF9119E and VEGAS_Deep_Learning_Models_20.5.0.0_INT_230227_09-44_9D758CF9 has made no difference.

Oh well, this plugin isn't essential to production, just something to play with. I can live without it until something turns up.

Please answer the question. What is the GPU? NVIDIA 40XX series?

Intel iGPU or ARC?

As JV demonstrates I can also confirm that Colorization does work in V20-403. My media is 4K Sony XAVCS and GPU 1080Ti. There must an issue with your hardware/system. You would need to answer RogerS to move forward with any help I think.

Thanks for confirming, @j-v and @andyrpsmith that's just what I needed. I will keep investigating. Since the other AI effects work without issue and Colorization worked before the blackout, The Intel 620 graphics (latest drivers) may or may not be significant.

Again, I'll wait and see what develops, that plugin is not critical to my workflow. Thank you both for your input.

Works here on all my machines. With AMD and Nvidia gpus. And Intel gpus & igpus from Arcs back to hd630 on an old Nuc... see my signature for driver versions. It uses the gpu selected in Vegas Video Prefs by default. Also helps to select that same gpu in Windows System/Display/Graphics:

Also make sure the correct Vegas Deep Learning Module for vp20 b403 is actually installed... look in Windows Apps and reinstall if in doubt. Note that running the same version of Vegas DLM twice in a row uninstalls it and it needs to be run a 3rd time to actually get it back.

I posted a few screen shots of results with the Vegas AI Torture Test as soon as I got b403. See this other thread.

As a for instance testing just Colorization, here's a screen shot of the Hiker video, normally in Color, with the Black & White FX to make it Monochrome. And then with Colorization activated next in the FX chain:

Not quite a natural as the color original but not bad.

@Howard-Vigorita Could you confirm what your values are here in latest Vegas version, and do you think there's any point to trying to force the GPU models to work. I haven't been able to work out how to do that, I keep removing the -1 setting from preferred DNN device and restarting, but it keeps coming back and from what you've said that -1 forces CPU AI processing

Is the Intel GPU the Intel HD630 or UHD630? Look in device manager/graphics.

@Former user The dnn device looks like it auto-tracks the device in Video Prefs if dnn mode is auto-set to DML. So when I select the 1st device in Video Prefs, it auto sets device=0. If I select the 2nd device, usually an igpu, it comes up 1. If I select Off in video prefs, it comes up with device = -1. There can also be interaction with the Windows graphics settings changing the order of devices in Vegas Video Prefs and/or moving which gpu gets the Optimal tag... ideally, the gpu in pcie slot#0 should be listed 1st in Video Prefs, get the Optimal tag, and be dnn device 0.

@Howard-Vigorita Thanks for the details

I've now been able to activate the GPU AI processing. Some crashing that seems to be related, but I was able to get 12fps at 4K, and 72fps for 720P colorization. With CPU AI I was only getting 7fps at 720P. This is progress, unsure if the inability to use GPU AI processing was a deliberate choice by Vegas due to instability or if I was experiencing one of the many related bugs with the AI models.

I"ll be happy if the GPU AI processing remains after numerous restarts.

@Former user Can you run the 2 torture tests without crashing? I usually time with either a vce or nvenc default 1080p render template. @Sassylola went from worst on a 4080 to best with 4090... maybe settings changes were involved too.

@Howard-Vigorita The crashing was at 4K, at 1080P is fine so far. My results are slow. I am thinking it's my CPU (AMD 5900X) because CPU load is still very high, but it's no longer constant 100% . I am thinking it requires both a fast modern CPU and medium GPU for good results. The GPU I have, the CPU I don't.

The SassyLola 4080 incident is likely them experiencing the same problem as I did, with Vegas setting DNN Device to -1 and deactivating GPU processing, so it must use CPU due to buginess with AI processing and 40 series, or maybe even unrelated to 40 series, just bugs, although I never experienced Vegas not using my 30 series GPU for AI processing.

@Former user That looks pretty decent. Better than my 6900xt and recording video at the same time. Which gpu is that?

@Howard-Vigorita I've been using a 4080 and 4090 to see which I want to keep. I had intended on keeping the 4080 because I don't really think the power is utilized that well in Video editors. The extra Vram of 4090 I"m finding really useful though. That render was done with the 4090 with a .950mv undervolt to stop my 750w PSU exploding. I could not get the GPU AI processing working when I had 4080 installed so can't say if a 4080 running full power and voltage would out perform or equal an undervolted 4090. If you go by wattages, can see the 4090 is not drawing much, I could guess a faster CPU would drive the GPU better in this instance and is likely for the poor performance compared to the other 4090's.

I know for the sake of the Vegas community I should swap back to the 4080 now that I know I can get the GPU AI processing working but I"M not much of a computer guy, always concerned I'll break something so at this point based purely on the extra Vram will keep 4090 installed and return 4080, and buy a new PSU.

4080 seems like a really nice card for video editing, 4090 too expensive for performance gained, 4070ti and 4070 have a small memory bus which affects NLE's more than gaming.

@mark-y Thanks for pointing out which driver versions are affected. Which Intel GPU do you have?

There was a typo in an earlier post. The GPU version is Intel UHD 620. @Vegas_Sebastian

New to forum Less than a year ago I purchased vegas pro 19. I am trying to colorize old black and white films

I cant find the plugin any where. I went on tech support chat and it doesn't allow me to chat. It says start typing , but nowhere to type, I see that they don't support old versions. Sounds like support is deliberately gone unless you purchased recently. Is there a way to get "deep learning curve for VP19 and this plugin?

@Bob-Wolf start a new post. What you are writing about has nothing to do with the original post. That way, you can get help specific to you issue.

Also, this thread was about the DLM in vp20 whose internal settings operated differently from those in vp19 and has continued to evolve with much improved reliability.
