Topaz Video AI is listed under Video Editing & Repurposing, in the Content & Media Generation category on Flocci AI Tools. Local GPU-based upscaling to 4K/8K plus SDR-to-HDR conversion. It is free to trial, then paid, and it lives at topazlabs.com.
Topaz Video AI offers a free trial rather than a permanent free tier, so access ends when the trial does. If you need something with no clock on it, the alternatives page lists the free and freemium options in the same category.
Topaz Video AI does 3 things the catalog singles out: Local gpu-based upscaling to 4k/8k plus sdr-to-hdr conversion; ai frame interpolation for slow-motion generation; desktop software, not cloud-only — no per-video upload needed.
CapCut is the closest free alternative: it sits in the same Video Editing & Repurposing sub-category and is free tier + paid plans. Captions, Clipchamp and Descript also start free. The full list is on the alternatives page.
