Yeah, I’ll open a ticket. Just checking to see if there was an obvious solution.
It happens with all the models, and with all the output formats.
Yeah, the topic of a forum shouldn’t be a long string like this. There should be a single topic for each specific issue. No one is either using or administering these forums as they are designed to be used.
It has dual GPU support in experimental under preferences.
This is @AiDon’s job, as head Moderator.
Based on posts in other threads, I have a question: Do you see V9 models in your model list? If so, you downloaded an accidental release that occurred after the initial 1.7.1 release. The V9 models don’t work yet, and apparently the version that had them has other problems. The bad 1.7.1 download has been replaced by the correct one, so if you have V9 models uninstall, then download again and install.
Back to crashing again. Latest studio drivers, 1080Ti
Spend all day today to get this to render-crashes hours in. Tried lots of settings.
Is it any faster running from command line?
can’t say for sure, i had nothing but issues when trying to use the GUI. as soon as i’d load a clip, it would freeze up. figured out the corresponding command line for the output i wanted, and ran it with powershell. it still launches the gui to run, but because there’s no setup, i haven’t had it freeze up. worth a shot, but i don’t know if it’ll help with your hours-in freezing problem.
Thanks. I’ve updated my BIOS (Zen 3 support) and updated every driver on my PC so will see if that helps.
I’ll do a fresh install on another drive if needs be just to see if its my 6-month old installation is glitchy.
Hey guys, since I’m still very new to the whole upscaling business. With the help of a friend, I’m currently trying to upscale cutscene (480p or lower) from an old game and well, I wondered if you could give me some feedback on my workflow.
- Handbrake: Converting the video with no filters, same resolution/fps/quality into mp4
- Dain: Interpolating to 30fps (if necessary)
- Topaz VEAI: Upscaling to 1080p with Theia-Detail/Fidelity into PNG
- AviSynth + FFMPEG: Converting the PNGs into mp4, adding some film grain and muxing the audio
What do you think?
Should I upscale to 4k? At the moment I don’t upscale to 4k becaues I can see a big difference and also I think maybe from 480p to 4k is too much, but maybe I’m wrong.
Also should I maybe choose another file format or a different work order?
Thanks in advance 
Most of what I do is upscaling 480i video. In Handbrake, I do apply filters
- Detelecine & Interlace Detection - default;
- Deinterlace - Decomb & preset Default;
- Denoise - NLMeans & preset Medium, Tune - Film;
- Sharpen - LapSharp & preset Medium, Tune - Film;
- Deblock - Medium & Tune - Small);
For video settings, I use:
- Constant quality @ 18 RF;
- FPS: 29.97 (as I’m using for NTSC tv) - you can change FPS in Handbrake;
- Encoder preset - Fast;
- Encoder Tune - None, Fast decode checked;
- Encoder Profile - High or Auto;
- Encoder Level - Auto;
- Advanced options - keyint=8:brames=0 (to smooth frames);
- Dimensions (Important for good upscale in VEAI):
a. 640x360; (This is a downscale - for my usage, VEAI does best at a 2x upscale, so 720p output is good for me - if you want to go to 1080p, try using 960x540 then do 2x upscale in VEAI);
b. Auto cropping;
c. Anamorphic - Auto
VEAI: Upscale 2x into 8-bit TIF (my preference - PNG is compressed and slows my editor way down, TIF doesn’t do this)
As with everything, play with your settings to see what works best for your desired output.
- Handbrake with constant framerate (audio highest possible), de-interlace off. If the constant framerate isn’t on, it’s a hard job to get the soundtrack right (if the original source has dropped frames or vfr)
- Deinterlace always using QTGMC using Staxrip (Easiest way for me). With QTGMC the quality goes to next level compared to Handbrake settings.
- VEIA with whatever settings makes your footage look best 100%/denoise first.
- When the 100% conversion is ready. It’s time to do the 4k upscale.
Quality settings with each step the highest you can tolerate.
@david-3912 what video editor do you use?
@osol I guess the denoise from VEIA is better than the one from Handbrake? Also do you output the denoised files as PNG and use AviSynth to get again a video?
I use HitFilm.
Please help me, I don’t know why the new 3090 is slower than the old 2080!!!
i9-10900K 32G DDR4-3200 RTX3090
From the another AI based video software forum:
“Nvidia has limited the RTX 30 with a new driver, not Compat with below CUDA 11, we found a solution and will update the fix in two weeks or so.”
So, maybe VEAI also has the same problem?
Also I can’t run the VEIA 1.7.1 at all. It just goes blank after few frames. Nothing wrong with my PC. Software from competitor works perfectly without any crashes and every other software works perfectly.
Hopefully there’s an upgrade coming soon, as I feel like I wasted money on this. Before the purchase VEAI worked perfectly. 
Bug:
Video imported from iPhone shows upside down when opened in VEAI v.1.7.1
-It doesn’t seem to affect the way the algorithm works but it’s pretty annoying.
Please add a tool to rotate video in future versions?
It seems that for my test video 1.6.1 performed better than 1.7.1. Here are my results:
CPU: i9-9900K
GPU: 1070 GTX
I am GPU bottlenecked as I see in HWMonitor that GPU utilization is at 100%.
Video used: 640x360, 29.97fps, progressive → upscaling to 1280x720 (200%) with Gaia-HQ.
OS: Windows 10
VEAI 1.6.1: 0.38 sec/frame
VEAI 1.7.1: 0.56 sec/frame
I rebooted my PC 2x and did not run anything else except VEAI. I also updated drivers to the latest studio drivers and then also to the latest game ready drivers. Updating drivers had no effect on VEAI performance. I also recommend a reboot before running VEAI because using it after letting PC run for a while seem to cause a little performance loss.
For me using a 2070 1.6.1 is smth like twice slower than 1.7.1 (using gaia and 720p to 2160p)
RTX 3090 should be more than 2x faster than 2080. RTX 3090 has a lot of VRAM, which VEAI may not use. I would recommend running multiple instances of VEAI on the same GPU for better performance. Select Reduce GPU usage in preferences when running multiple instances. If you still have issues create a support ticket and we can look into it in detail.
