Hi,
after an update to the v.3.0.5. my Topaz Video AI crash everytime at the beginning of starting “Run Model”. I´ve tried a several different files and formats, different export settings, but nothing helped. Is it possible to downgrade your software to previous versions pls? This update doesnt work on my workstation 
Preview images are desynced which effectively makes them more or less useless.
If you purchased v3, you should be able to download and use any previous version. You can find download links on this forum.
What is studio drivers? Better than WHQL releases? (Windows Hardware Quality Labs)
Hi, could you make sure you have detailed logging enabled in advanced settings and then send us logs from a session where this occurs?
Previous versions (e.g. 3.0.4) listed “Quality mismatch between 2.6.4. and 3.0.x for some models.” under “Known Issues”. This line, along with my own comparisons between 2.6.4 and earlier versions of 3.0, indicated to me that the models in 3.0 were—at least in some cases—of worse quality than those in 2.6.4.
So 3.0.5 has gotten model quality back up to where it was before.

It’s the same driver as the game ready, but released less often and supposed to be more stable.

I’m using the FFMPEG cli.
- This worked in 3.0.4
- This is the current nvidia studio driver, I also downgraded to the previous with no change (I’m back on current)
- h264_nvenc works fine

Might be a GTX issue then with 3.0.5. I have machines with RTX 20 and 30 but they don’t have Video AI installed.
I have a feeling this is similar to what I posted about here: https://community.topazlabs.com/t/topaz-video-ai-3-0-5-0-b/37094/27?u=david.123
Try adding “-b_ref_mode disabled” in the video encoder section on the command line (after -c:v) and see if that fixes it.
Yes, it is unfortunately an issue with that particular card. The NVENC encoders in FFmpeg were updated to a newer version that has support for HEVC B frames, and it appears that setting defaults to enabled on all cards even if they don’t support it.
HEVC B frames are only supported in hardware from 7th gen (1650 Super) onwards. For older cards, you’ll need to provide -b_ref_mode disabled as the other poster suggested.

If this is the case, NVENC HEVC will be broken for anyone trying to use a GTX series card. Not everyone is capable or willing to edit their encoders.json file, so some sort of fix will need to be added to the application.

The most outstanding thing the 3.0 (up to 3.05) doesn’t let me log in, and I spent my money for nothing. Same nothing as topaz tech support.
It’s gone from something that was fun to tinker with, to a complete waste of time. It’s truly frustrating, and making things worse, is all the technobabble in this forum, which makes absolutely no sense to me and is totally unhelpful. No offense to those who know all this video technical stuff, but I thought this software was for the novice to, but it no longer appears that way. It would be like me coming into this forum and talking about a recent mast moment exceedance, that occurred in an Airbus H145 helicopter. I’m sure I’d get a blank stare from just about everybody in this forum, which is how I feel while reading though most of these forum messages.

That did fix it.
EDIT: I updated my encoders.json but it would be nice if Video AI did that for people in 3.0.6.

It’s likely there is something on your system that is blocking Video AI from accessing the Internet to talk to the Topaz activation server.
This is not Topaz’s problem.
I recommend you use Google and find out how to create a firewall exception for Video AI.
Please can we have ProRes 444 (and ProRes 4444 to preserve alpha channel) in Windows too. It was advertised as having this but it doesn’t exist in Windows.
First time user here…
I am trying to deinterlace HDV footage (.mt2 files from the Canon HV20) and Topaz constantly crashes when I try to export.
Is this a known issue?
I hope they add it quickly, because the current version is absolutely useless without 2.6.4’s grain controls. Honestly, I’m REALLY pissed that I spent money on this beta crap.
