Topaz is becoming increasingly annoying, no more new features, Starlight that I’ve never been able to get to work, lots of bugs that shouldn’t be there, lots of unhappy people who are always complaining about the same problems that still haven’t been resolved. I don’t know what’s going on, but I don’t like it. It seems like the people in charge don’t know how to use the app, which is sad. I hope it will eventually be fixed and that we will have a platform that works properly. I don’t even want to update anymore because it’s so useless. I am extremely negative and I don’t like it.

Nope, it’s not your imagination… the quality IS there and only there.

I have a option to rent a server with any gpu i want for 1 week. What is the best and GPU for starlight? H100?
Here’s a batch file that I’m using on Windows with Video AI 7.1.0 to upscale 720x540 to 1280x960 (1.5x).
In my environment, the TVAI_MODEL_DIR variable is set to C:\ProgramData\Topaz Labs LLC\Topaz Video AI\models

Please send feedback to win11 icon in task tray. Right now, no data is shown. It would be awesome to see progressive % complete as other apps do. Seems like that would be an easy update and nice quality of life update. There’s otherwise no way to have the app minimized and know what state the exports are in.. thanks!

Can you send the logs to the support team at help@topazlabs.com so we can get the info to the devs?
The devs are aware of this and it is being worked on as quickly as they can.

I really do hope they’re aware not only of the RGB bug but also of the abysmal quality on AppleSilicon since 1.0.3 and that only the 1x SL model seems to work regardless of the chosen output resolution.

I still do all of my starlight mini work on the last official version of Topaz Video AI
I never uninstalled it….even though I also have the studio version installed.
I don’t seem to have any problems and the quality is quite good…….. incredibly good… eye popping good compared to the VHS stuff I started with.
I think they’ll get Studio straight at some point and even solid support for Mac and AMD.
But right now I’m kind of in the mode of…. If it ain’t broke, don’t fix it!
Even though it’s excruciatingly slow. If you don’t have a separate machine set up to just do your rendering I don’t see how you can really function with how slow it is.

That’s the point.
SL mini already did work slow but with good quality (roughly comparable to TVAI 7.0.2 on NVidia) on the Mac in the 7.2.0.3b and Studio 1.0.
Then they totally broke it in Studio 1.0.3 and instead of fixing again even made it worse in 1.0.4.

Vielleicht die falsche Stelle. Der Patch 1.04. lässt sich installieren,. Zunächst werden alle Files auf den PC kopiert (laut Anzeige) und die Installation der neuen Files beginnt, nach ca. der Hälfte erfolgt ein Rollback. Mit anschließender Fehlermeldung, die besagt, dass der PC nicht verändert wurde. Somit arbeite ich zunächst weiter mit der Version 1.03
Yes…they “broke” one of those time tested euphemisms….
And now we have Nvidia folks concerned about splitting available development time for Mac and AMD.
kind of a mess right now.
2025 was a….
Let’s just say it nicely; “an exciting and very challenging year for Topaz.”
Us as users even more so….

Anstelle über die Upgrade Meldung im Programm, versuche den Installer Download hier
AFAIK, no diffusion model can process anything larger than 720p. To output 1080p the video is tiled into 4 sections, each is processed separately (sharing metadata) and then reassembled. One of reasons it is so incredibly slow.

…and the communicated roadmap is “improving Project Starlight” yes we can see the improve..

Dear Henry, how about 1.0.4 and Mac OS 26? I’ll keep Sequoia 15.7.2 until I find a notice that Tahoe 26.1 does not cause conflicts with Topaz Video 1.0.4
I have been using macOS 26, including Apple developer betas and haven’t seen any impact.
It doesn’t here.
Apart from Topaz‘ bugs I don’t see any obvious issues with macOS 26.
Does that mean that upscaling to 720p is much faster than 1080p with starlight?
I’m not sure if this is the case, because as higher you set the output resolution, as much slower it is. When the model just can do 720p or 1080p and everything higher is a “cheap” Lanczos upscale, then why it gets that much slow? For SLS it’s the case, it does 1080p max and scale to selected resolution with NYX afterwards, but SLM is different does not.
