Hello everyone, A new release of Topaz Video AI is now available. **v3.5.2** Released October 3rd, 2023 **Downloads:** - [Windows](https://downloads.topazlabs.com/deploy/TopazVideoAI/3.5.2/TopazVideoAI-3.5.2.msi) - Mac - [DMG](https://downloads.topazlabs.com/deploy/TopazVideoAI/3.5.2/TopazVideoAI-3.5.2.dmg) | [PKG](https://downloads.topazlabs.com/deploy/TopazVideoAI/3.5.2/TopazVideoAI-3.5.2.pkg) **Changelog from 3.5.1:** - **Adds Iris options to select between Medium/Low Quality.** Medium will use Iris-v2, Low will use Iris-v1. - **Adds 1x & 2x deinterlace options for Interlaced videos when keeping original fps.** - **Adds detailed tooltips for all preferences.** - Adds info about Iris & Nyx models to Progressive models tooltip. - Adds detailed metadata for Iris & Nyx enhance models to exported video file. - Adds “Noise” value for enhancement models to video metadata when not zero. - **Fixes ffmpeg issue causing exported video to sometimes get stuck in playback.** - **Fixes for rotation issues for files with rotation metadata.** This was causing many of the issues like “file opened upside down.” - **Fixes issues selecting “original” fps option in fps selector.** - Fixes FPS display to drop extra "0"s when the fps is a whole number. - Fixes filter order when deinterlacing which should lead to higher quality visual results. - Fixes metadata for exported video when using Iris to only say “Deinterlaced” when the original video was actually Interlaced. **Iris LQ/MQ** After reviewing user feedback, our research team has decided to split Iris into two models depending on input quality. Iris v1 will now be called “Iris LQ” and is recommended for very low resolution videos and highly compressed content. Iris v2 is showing better performance on medium-resolution videos (more than 480, less than 1080) and will now be labelled “Iris MQ”. We believe this is the best way to communicate the specific strengths of each model, and we appreciate all the feedback that came in after the initial release! **Known Issues:** - Currently not all the models are supported on Intel ARC (model support will be added week to week). - Videos with mismatched metadata and streams will display incorrect duration - Frame number preview length may shorten on app restart ---

Same problem for me when updating from 3.5.1 on Windows 11. Running the installer a second time and selecting the “Repair…” button fixed it. ---

Thank you @fumio and @Skwerl. We have paused the update on Windows for now and will get it fixed ASAP. You should be able to continue using the 3.5.2 install you have if it’s working already! ---

Downloaded Windows 10 3.5.2 installer file from the website and installed directly from that, not via the previous TVAI versions. Updating to 3.5.2 with 3.5.1 still installed fails with the error messages posted above. Updating to 3.5.2 by the same method with 3.5.0 installed is successful with no error messages. Updating to 3.5.2 by the same method with 3.3.4 installed (on another Win 10 PC) is also successful. This suggests to me that the problem may lie within version 3.5.1. ---

Installed this version to see if it fixed any of my issues, did not work at all. For some reason, since 3.5.1 the preview and encoding does not work at all on CPU anymore, it does when i switch to GPU, but this makes my card work instantly on 100% causing a temperature range of 97 degrees Celsius!!! ---

Thanks, everyone. We determined the install issue mentioned above could happen if you had **3.5.1 installed** and updated to 3.5.2 with the **MSI installer** (downoad link). ~~You have 2 options that should both work:~~ 1. ~~Download & install the update with the in-app update button.~~ 2. ~~Do a clean install of 3.5.2 using the msi.~~ Edit: the regular download link should work just fine again. ---

Try doing a clean install of the app with the 3.5.2 version (uninstall Video AI and then install 3.5.2 from the download link). Let me know if that helps you out. If not I’ll get you in touch with a product specialist that can get you going again! ---

Already tried that, the preview and encoding still does not work on CPU, only on GPU, but than my card ramps up instantly to 100% and 97 degrees Celsius! (and its a 8 gig card, AMD Radeon RX 5700xt should more than be able to work without issues) Going back to like 3.4.4 is the only fix. ---

I’m gonna wait a week before upgrading to 3.5.2 to make sure it’s not as broken as 3.5.1 was. So far 3.5.0 has been stable. ---

Hi there, we’ve looked at the install process for the MSI package and we think a clean install will resolve these errors: > **[How to Clear Your Topaz Labs Registry Entries (Windows) - Topaz Labs](https://support.topazlabs.com/article/99-how-to-clear-your-registry-windows)** > > If you get error messages or have issues with our apps, often uninstalling the program, clearing the registry (this article), and then re-installing the latest This affects some users upgrading from 3.5.1 to 3.5.2 by downloading the .msi file. 3.5.1 users can also use the in-app update utility without issue. ---

Guess I’m late to the party. I updated from within the GUI and have had no issues. I suppose I also had no issues with the last version either. ---

I installed version 3.5.2, which, as you promised, would solve the problem, but unfortunately the problem is still the same. I did several tests by changing the input parameters, but each time I get an error a few seconds after starting the process. Still the highest version I can use is 3.3.9. My computer is: MSI Katana 17 FHD i7-12650H 64GB RAM GF RTX 4060 8GB 1+2TB SSD Windows 11 I spent PLN 8.600 on this computer and almost PLN 1.400 on Topaz Video AI… Will this program ever work properly? ---

I like that Topaz keep releasing frequent updates. The new option to select input video quality for the Iris model is great! One suggestion, can you add more “Quality Level” control to the output settings? The issue is I output a 4 minute 4K video in high quality mode, the file size is 5.3 GB. I change it to “Medium” quality and the file size is only 770 MB. The file size difference is too dramatic. I expect it to be ~3GB for “Medium” quality and less than 1GB for “Low” Quality’. We need more “Quality Level” control on output video. Instead of low,medium and high setting. Can you change it to use a slider control that let user slide quality level from 1 to 10? ---
