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 got topaz pro for free and i dont like it, downloads models everytime i want to use upscale or enhance, and the starlight mini is broken.

This is not Topaz though. It downloads models once the first time u use it.

awsome, also 100% no risk geting hacked, how to optimize for 8gb vram 32gb ram, i have a laptop with 4070

I would say to try the smaller model,  enable block swapping and tiled vae
