Topaz video enhance ai gpu not working5/16/2023 ![]() Still, it may be unreliable if the frames contain challenging scenes such as low contrast regions, illumination changes, motion blur, and moving objects. “Traditional methods rely on finding and matching individual feature points between frames to determine the camera motion. ![]() Sadly I didn’t see any major speed improvements overall to the export speed, but that may come in time. You can now set up multiple previews to render out when you are at the testing stage trying to work out which model is best. Parallel TasksĪnother fairly big change is better support for working with multiple videos. With the new VAI v3 on the right you can do both at the same time. With VEAI v2 on the left, you choose between Chronos (Slow-mo) and an upscaling model. Stacked filtersĪside from stability and under the hood improvements, probably the biggest change is that instead of only choosing one model, whether it was an upscaler or timewarp, you can now turn on both at the same time – for example if you wanted to slow down and upscale some footage – bearing in mind that Topaz also slows down cleverly too, interpolating new frames based on what in theory should be there instead of just repeating them (like the new feature in Nvidia’s DLSS 3 for games). That said there are a few new features which most will be able to take advantage of. I think whether this release is a big deal to you will depend a lot on whether you are one of those users who had those “pain points” they mentioned in their FAQ or whether you are someone who can take advantage of the increased access to the backend FFmpeg filters. Certainly they had some bugs to iron out during that time, but overall I didn’t personally see that much difference over Video Enhance AI v2 aside from the differently designed GUI – at least not as much as I was expecting from the version and name change. Some months back I noticed Topaz had early beta access to this software so I’ve been running it through its paces. Topaz Video AI v3 unveiled a Stabilization model that allows users to stabilize their videos and keep the original resolution.” The GUI will merely call the FFmpeg backend and spawn separate processes. Topaz Video AI consists of two independent parts: the Graphical user interface (GUI) and the backend FFmpeg filters. This approach allows us to focus on our core expertise to create and improve our models to perform better on all user videos. To address these concerns and allow the addition of new features, we decided to rewrite the code base. ![]() This was hampering the development of new models and processes that require multiple passes, like stabilization, scene detection, etc. All the current models operate on this assumption and as a result, had issues processing videos with variable frame rates, repeated frames, scene changes, etc. Most of the issues stemmed from the fact video was being treated as a series of constant-rate images. ![]() “After reviewing the list of pain points our users experienced in VEAI, as well as the feature requests that were received, it became clear that VEAI had to change significantly to evolve into a product enjoyed by both beginners, and experts alike. According to Topaz, this is more than an upgrade from v2 to v3 and this is why presumably they’ve renamed it, from Video Enhance AI to Video AI – it’s a completely new version of the software. Topaz Labs have now released Topaz Video AI v3. I used it recently for a blurry photo of a face and with “Recover Faces” turned on, it was remarkable the difference it made. This is also very popular for photos – Topaz have their three software programs – Gigapixel AI, DeNoise AI and Sharpen AI – that they’ve recently combined into one called Topaz Photo AI, which always seemed to be where it would go. studying thousands and thousands of video pairs at HD and 4K and learning how to get from one to the other. It is a piece of software designed to bring back details when moving from HD to 4K say, by cleverly estimating what should have been there through machine learning – i.e. Topaz Labs have become one of the leading names in Upscaling in the past few years with their Video Enhance AI v2 standalone software – doing very well in my head to head tests.
