FlashVSR+ vs SeedVR2

[naxci1]

I've been trying to get it to work for two days. It's a very rudimentary application. Since it was written for the H100, running it on 16GB of VRAM was quite challenging. I finally got it working and ran some tests, which I'm sharing. It corrects close-up faces well, but it distorts distant faces significantly, and it also can't correct inanimate objects. I think it has something to do with model training. It says it runs at 17 fps on the H100, but it took a long time with Tiled VAE on my GPU. It's faster than SeedVR2, but I can say that. But SeedVR2 is definitely better quality-wise. You can see this for yourself by looking at the images.

On the left, FlashVSR+ is upscaled at 4x, and on the right, SeedVR2 is upscaled at 3x.

I couldn't make a full comparison because I couldn't upscale SeedVR2 by 4x, I could upscale the other one by 4x, SeedVR2 is upscale by 3x, which makes it look different, and I can say that FlashVSR+ upscale by 2x is really bad.

Thank you so much for sharing the results @naxci1 , it's much appreciated. The model plays a big part but the integration code is also equally valuable in terms of user experience and performance/optimisation.
For a moment I got scared about FlashVSR and what that would mean to SeedVR2. But at the end of the day, I think everything we've done here still has a lot of value, hence the fact I'm continuing my work on the next update of SeedVR2

Once it's out there, if there are things that flashVSR does better than SeedVR2, we can potentially look at an integration/combination of the two models where you could have the same upscaler UI and chose between the 2 models as needed. Food for thoughts / for later if it's valuable to the community. Thanks

What you do is fascinating, taking the time to see the differences. I am very grateful to you and also to Adrientoupet for the great work you are doing with all this. I am using it with a 4080 16GB and I am delighted with the results.

Thank you for the kind words, it really means a lot.
