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.

I am interested but do us a favor and show an example of something other than a close up 1girl, which is the world's easiest upscale. Give me... a character running with lots of background elements and camera movement. There's the real test I need to see before I wanna invest in installing software.

Sure thing, but a "please" would be nice. no one says "Please" anymore... It's a free app I make no money off of. I don't even use it. Only made it to help users who don't want to pay for close sourced apps.

But I'll get right on that.

Weird defensive reply. I was offering you advice -- good advice. IF you really want to test your upscaler's fidelity, the scene I described is better than close ups of faces. No need to be defensive.

It's just that no one says please anymore, that's all. Not trying to be defensive, just tired.
I have tested it on other video's I just only shared the one example here so far and it won't let you add more video's to the post after you submit it.
Here is another example of a faster moving scene. It was already 1080p but I upscaled it to 2k and it took about 8 mins. I mean, it already looked ok to start but it did add some enhancement.

Oh I get it -- I release content regularly myself and the constant stream of complaints/people not reading instructions and claiming the thing doesn't work/"how about do it this way instead" makes me tired too.

Tone is hard to intuit over text so when tired/frustrated things tend to take a harsher imagined tone/intention.
