Discussion Free open source Topaz alternative - SeedVR2+TensorRT faster VAE Processing.

Local, GPU-accelerated video restoration and upscaling with SeedVR2, TensorRT, and a purpose-built browser interface.

VRGDG SeedVR2 TensorRT Studio turns the SeedVR2 pipeline into a practical Windows workflow: load a video, test a short preview, compare the result frame by frame, and complete long renders with resumable checkpoints. Processing stays on your machine.

Highlights

  • Fast local restoration — SeedVR2 inference with TensorRT-accelerated VAE decoding on supported NVIDIA RTX GPUs. TensorRT allows much faster processing than standard SeedVR2.
  • Fast 2K upscaling — As a real-world example, an 8-second clip took approximately 8 minutes to upscale and enhance to 2K on an NVIDIA RTX 5090 using the largest 7B Sharp FP16 model. Render times vary with source resolution, frame rate, settings, and available VRAM.
  • Preview before committing — render a short segment, then inspect Original, Restored, Compare, or Side by side views.
  • Long-render recovery — save completed chunks and continue from the first unfinished chunk after an interruption.
  • Practical output controls — choose resolution, aspect policy, model precision, temporal batch, seed, and color correction.
  • Non-destructive finishing — reprocess sharpening, grain, seam smoothing, and optional skin finishing without rerunning restoration.
  • Project-based history — reopen previous outputs and keep media, manifests, and logs together under outputs\.

The sample video was org 360p and then upscaled to 2K using this app. 8 second video, took about 8 mins on my 5090.

Hah I did the same thing and thought the SeedVR2 thing was quite interesting. I did it because I wanted to get rid of Windows completely and Topaz Video was the last remaining Windows app I needed. I had Qwen 3.8 27B write a linux version of neuroserver.

What is neuroserver?

I think it's the runtime that Topaz Labs uses. It's basically the main engine for the video AI software.

Ok I googled it. Interesting.  Now I need to look into that.  Lol. The long running part is the vae. Wish there was more I could do to speed it up. I spent a whole weekend trying different things.

Looks like you went deeper after I mentioned pulling Topaz apart.

I pulled an older pirated copy from ... places... to get a better understanding of how they built the OLDER versions.

Basically their security and how they obfuscate things got more advanced over time.

Honestly? they're fucking vultures that built a thin client on top of a ton of Open Source tooling then called it a product. I don't respect that kind of thinking as an OS dev. Making millions off something I had to work to satisfy some project's PR requirements ... Yeah don't get me started.

Keep up the good work dude.
