Very useful printed out to show staff! Thanks

Hi Hopkirk

Thanks so much!


Would love to see a test going from interlaced DV, or even HDV, to 4K.

I have used Topaz to deinterlace and uprez mini DV to 1080p 29.97 and it’s pretty good. haven’t tried 4k yet. I mean DV is DV but with some color correction after It looks pretty good..

Hi Chuck

I’m currently writing a review of Topaz specifically so I’ll be sure to do a de-interlace test for that.


What About the Video2x project (Waiffu2x) or Anime2x with vulcan NNUE for those without strong video cards? been trying to run a docker version in cloud on google colab. Topaz Labs was extremely slow for me and doesn’t add much detail.

Hi Chris

I really wanted to get into that side of things, but it was beyond the scope of the article which already took a long time to research. I think it’s a really interesting area.


Am I the only one who thinks that it looks better before upscale? 4K looks kind of blurry on all of the samples. Though Topaz is the least blurry 🙂

Hi Alex – in the pictures I have the original 4K on the left and on the right is the specific tool trying to get as close to that quality as possible after I’d downsampled it. So in all the pics, it looks better on the left, it’s more a case of how close the right pic is. as well as how it compares to the right hand side of the first comparison “original vs simple 200% zoom”.

Nice article. You were using NVidia GPU for all this right? Would like to know now, with Radeon and Microsoft’ “TensorFlow-DirectML” claming AMD RDNA 2 GPUs have up to 4.4x performance gain. I would be interested to know if this is true because NVidia’s GPUs still scalped more than Radeon’s. TIA.
