Is there a way to sharpen video (like sharpen AI does for images) without changing resolution?
Right now I use sharpen AI to sharpen video that is saved as image sequences, then put those images back into a video. There should be an easier way.

I use Photoshop to break video frames into jpegs, batch the jpegs via PS, then use VirtualDub to stitch back into a video.

Sure. If you use the Proteus model (or Theia, for that matter), there are separate sliders for both sharpening and detail recovery. Just experiment with those while setting the output resolution to 100%. There are also sharpening algorithms in freeware like DaVinci Resolve which are pretty good.

I forgot to say the thing I want to sharpen is an out of focus talking head (itās an interview video) so I need some sort of AI face sharpen.
You donāt have to change resolution to use ANY model.
I usually use the first pass for cleaning up the video and use the second for upscaling. I have to use two-pass for most 80s and 90s TV on DVD.
Why in 2 steps? Do you use different AI models for cleaning and upscaling?
I often need two steps because the source material was just put on DVDs.
It wasnāt necessarily cleaned up.
The first model I use depends on the material, but I always finish with Artemis HQ for the upscaling to 1080p.
The only DVDs that I am upscaling that donāt need serious work are my super-bit version of āThe Fifth Elementā and (though I havenāt done then yet) the āBack to the Futureā Trilogy.
For some vintage DVD, the original material has some vertical ghosting line (or color band) (not sure how you will call it officially), how would you pick your first model in this case?
well I can say this. One of the 80s DVD series that is not great quality is The Golden Girls. Let me just say that using 100% denoise/deblock is a massive improvementā¦ Even when itās doneā¦I run it back through handbrake using slow HEVC then and audio back. The final file size is 300 to 500 MBā¦Itās crazy how much better it looks. I donāt have the patience to run it back through again. It already takes long enough. I just wish I had a more powerful desktopā¦can someone recommend a desktop tower I can use specifically for this? Something thatās available and doesnāt cost a fortune? Thanks
@mark40511 specifically, which model did you use for āThe Golden Girlsā? I only see the option of ānoiseā, but not sure which model is the best for denoise/deblock. Thanks.
well if youāre doing it from remuxās of DVDs, you would click the dropdown at the top that says clean up old interlaced footageā¦but in my case, I ripped my DVDās long ago and converted them to 480p CF 16 using handbrake. So mine were already deinterlaced. Since mine were already deinterlaced and I just chose āclean up old progressive footageāā¦ I tested it and previewed itā¦they looked good. That preset uses Artemis LQā¦Additionallyā¦I moved the H.264 slider down to like 13 because the files are so large after they are done, that I run them back through handbrake on a SLOW preset. Iām not trying to make them HD quality. I just want them cleaned up and I add some grainā¦Iām new at this, so Iām sure an expert at this would use different settingsā¦but they look 10x better on my big screen. When the files are done, each episode is around 3 to 3.5 gigsā¦Once I run them through handbrake converting them to H.265, each file is 300 to 500 MBā¦ I also turn audio OFF because I add that back laterā¦ There are a few episodes is season 5, 6 and 7 that are particularly blurry - even straight from the DVDāsā¦it made those looks 20x better IMO
Theia is very good with the oprions 0 90 0, but create a screening effect, like a net. Some of you know how to remove the screening effect?
Topaz Photo AI does by far, a better result.
The best way at this moment is render original video to PNG/TIFF/JPG , process all the images with Topaz Photo AI and then stitch together again in Final CUt/Premiere/yourfavouritevideoeditor.
It takes tooomuch time, but it is by far the best way.
Topaz Video AI is good enough to scale footage and do some tricks for enhance resolution, slow motion and sharpness with good looking footage, but if your footage is a bit out of focus, with some noise, Topaz Photo AI is the only way to solve this (nowadays)
