Does anyone else love this model?
Anyone have any issues with it for dvd quality to 2x upscale? Just wondering before I do a ton of converts only to realize there are issues.
I’ve tried a movie with it and it worked much better than the other models. No artifacts and no plastic looking people and doesn’t remove details like the other models do. Faces look better than Iris. No matter how much I reduced noise reduction I’d get plastic faces in scenes in people’s faces with all other models I tried including iris. Gaia doesn’t remove noise the way the other models do so it doesn’t ruin detail. As long as the movie is a decent dvd quality movie you’re good to go!
I don’t’ agree where topaz says not to use it below 1080p. It’s fantastic for that as long as the footage is high quality dvd.
My experience with Gaia HQ is that is can make monster faces for small background people.
It’s pretty good at doing nothing if it cannot make an enhancement. So the result is very similar to using a more standard Lanczos filter.
The main issue I had with it was that it tended to transform grain into texture on solid colors. So like a white sign would turn into a spotted white sign.
I see that now. All the enhancement models seem to have issues. The closest thing to perfection is the chronos model if they could just fix the artifacts around fences issue
Chronos has such a natural look to it, but it’s those damn square blocks of blur that come up anytime a complex background is there. Even certain shirts or wallpaper. It just makes it not worth it.
Apollo is jittery and has a speed up effect.
You need chronos smoothness and natural looking, but with less artifacts. If my tv can do it on the fly nearly as good, no reason they shouldn’t be able to fix this.
I’m going to try v5 apollo. In one scene it looked better than v8. I think v8 was trying to hard to increase clarity. Frames need to be able to blend.
Have you tried Artemis Aliasing or Moire V9, or sometimes Artemis Strong Halo V2 ?I have found them more natural looking than any other models for smaller faces.
Large faces most models do good job, SLP does excellent job. For smaller faces, it is totally different , almost all models change the face to different person (AI hallucination), if you really know the face of the person, this is more pronounce when you zoom in, all models including SLP models, SeedVR2 etc do similar face change. I have tried almost all the models, even SeedVR2, AIArtey, VideoProc, etc unfortunately no software so far does great job for smaller faces. Same resolution some might do cleaning job but real enhancement is unfortunately lacking so far.
The best I have seen for interpolation is do Apollo at 2X increase and then Chronos at 1.25X frame increase. That gets you ~60fps, Apollo makes most of the intermediate frames and Chronos fixes that unnatural motion you mentioned.
Proteus 4 with manual settings can usually get good results on DVD sources. It won’t be as good of quality as a Blu-Ray source, but it’s easily better than the original DVD.
Put all the sliders at 0 and only use:
Fix compression as the denoiser, 20 to 60
Improve detail 0 to 12
Sharpen or Anti-alias/deblur, never both at the same time. usually 25 is going to far. You want to find a scene with background branches or grass or gravel. Try to find the Sharpen or Anti-alias/deblur value that reduces or don’t give the weird circle-dot pattern that tends to result in most of the AI models.
Yes, I do this all the time. For example, I use Apollo to convert 24 fps to 48 fps, and then use Chronos for non-even interpolation, such as converting 48 fps to 60 fps.
in some of my test SLP produced less disorted small pixel faces than Proteus Natural, I think SLP isn’t mature enough yet to be applied to full movies, but if the jittering and dirty-face issues are solved, or at least mitigated, the long search will finally come to an end, because, as I said, SLP handles faces well and produces little to no alien fonts.
I tried the 2 pass method. I made a thread on it earlier. It doesn’t work. You end up with stutter/judder in odd places because you create a variable frame rate. It drove me nuts! lol
Before this, the last thing I tried I was just using apollo 4x to 100fps. And then I tried chronos to 50fps. Chronos was natural and smooth, but has major artifacting issues.
I’ts basically impossible to convert to 60hz with these models from a 24fps source without occasional stutters because the frame time is all out of wack. The models need to be able to do even frame insertion 2x or 4x. I went through a ton of movies and ended up deleting them all. It was a mess. Trust me.
Uneven interpolation causes variable frame rate and you’ll notice during pans you’ll get occasional stutters. It almost seems like the the frame gen is not working for a second. If you have a keen eye you’ll see it during it pans.
These models can’t do uneven interpolation. I think I finally found a solution.
I output to images then encode it to video later. Variable frame rate is not an issue for me.
It’s been a little while since I’ve dedicated time to interpolating a video. Mainly I’m reporting off of last time where with just Apollo, I noticed that the motion was incorrect or weird, but on the same movie with Apollo + Chronos, I didn’t notice it being weird and there were no blur patches like with just Chronos.
That was just one movie though. I probably need to do a lot more to really figure out if it’s good enough or not.
It’s not even the Variable frame rate is an issue. It’s because it causes issues where pans are not completely smooth if you don’t go 2x. It causes an occasional judder issue if these models are not 2x or 4x. You’ll get an occasional stutter during a pan ruining the smoothness. I noticed it after doing a few movies. If you pay close attention you’ll see it. Otherwise I would just go apollo to 48fps then chronos to 60, but that causes those issues.
I just did a new test. I went from 25fps with shutter encoder then to 50 fps with apollo, then with chronos to 100 fps then set tv to 100hz. I’m going to test it out. The first 15 minutes were great. This might be the solution I think.
It’s an “even” interpolation so no odd stutters and no blur pathches because chronos can handle 50 to 100fps without issues, and then the 50 to 100fps gets rid of apollos wierd speed up effect/unnautral motion caused by uneven frame timing in the model itself I think. Then frame matching the tv to 100hz. Only usuable on computer obviously. My computer is hooked up to my tv so its’ fine.
Gaia 2 model does a decent edge enhancing/debluring job when used in 100% mode for blurry PAL dvds where the source is an old telecined copy of a PAL broadcast tape, the result looks sharper, natural and without noticable artifacts. 200% upscale would distort a lot, but at 100% it seems to be the best for this kind of source, where other models like Proteus or Iris only worsen image quality.
