@@Reziac yes, some "remasters" are exactly that - that is how it was even before AI and all that - sometimes there just was no other option. In the case of movies or TV shows shot onto real film, you can re-scan the film at a higher resolution, as film tends to have very high resolution - technically, the "pixel" size of film is how big a grain of the photosensitive material is AFAIK. But many TV shows have been shot straight to magnetic tape and if it has been recorded in SDTV resolution, then that is all you will ever get. If that is the case, the only thing that can be done is add another layer of post processing to the original material and hope it does not look too terrible on the "remastered in HD" re-release.

All three products work, and even the most expensive offers a perpetual license for a fixed entry price. Thanks so much for sharing, I learned a lot this morning.

something interesting for photos is technology that astro-physicists use to sharpen pictures of distant stars/galaxies, but works for regular pictures. the premise is that all blurry pictures actually do contain thr pixel data for a sharp picture but, they're not in the right place. when you know the exact characteristics of the lens and know or work out how the camera settings were, you can put the pixels in the right place. in the old days we used to use a sharpen filter, which doesnt produce very good results.

I can't speak to the other programs here, but I know the output you get with Topaz Labs' Video Enhance AI generally varries IMMENSELY based on both the quality of the input video and the choice of which AI model gets used. The Artemis HQ model used in this comparison is one of the safer options if you don't want to spend much time fiddling with settings as some of the other models tend to apply more aggresive processing that can result in output that looks rather artificial, but my own go-to model of choice is Proteus as it gives the user some additional settings to dial in exactly how much processing gets applied. It takes a bit of effort on the user's part, but the better results are generally worth it IMO

Topaz created a low file size because he used a Constant Rate Factor of 33, which introduced a huge amount of compression. I've used Topaz to upscale many of my DVD's to 1080p and use a CRF of around 16 -17. The file sizes are much larger but everything is crisp. I then color correct with DaVinci Resolve and try to get a more manageable file size. He also used the Artemis AI Model, which doesn't always give the best results. Proteus Fine Tune is the way to go if you want everything to look great. I suggest you check kraz3yivan's channel. He uses Topaz to upscale Star Trek Deep Space 9 footage. You can see what kind of quality to can get with Topaz and DaVinci Resolve.

Medium format film is still the best quality if you are constrained by not having a high five-figure or low six-figure budget for the sensor, especially with a slow film in the 25-40 ASA range. It is why it was always used for outside advertising photographs (studio photographs used plate or sheet film that was even larger) that were intended for enlarging to fill posters the size of a house that came on several rolls to be pasted up, and why the camera that was chosen to go to the moon for still images was a Hasselblad - or rather two of them for each landing mission (and they are still there - free to the first person who can collect them).

I don’t understand why you favour AVC so much because the details in the background have completely been overprocessed and look smeared. Same goes for the body of the butterfly and the flower that the butterfly sits on, it’s been deformed and looks smeared, not at all ‘natural’. I think Topaz and Waifu did a much better job at presenting a video that didn’t look over-sharpened and artificial. Comparing the blurry background in the top left corner, I would say Topaz does a slightly better job and maintaining the details whereas Waifu was a bit more aggressive in smoothing things out. That’s my opinion anyway and I must again say I am amazed the AVC upscaler came out as the subjective best due to all the artifacts it seemed to generate (including the shimmering but also the distortion of the yellow flower at the bottom left).

Ah, I don't know. The AVC Labs output is clearly trying to "sharpen" the bokeh in the background, which is making it very cartoon-ish (like someone's applied a "posterise" colour reduction filter to it). While Waifu and Topaz seem to have correctly interpreted bokeh as background and not tried to "fix" that which isn't broken (Waifu's done some smoothing that looks the most realistic to me). Indeed, I generally feel that the AVC Labs is trying too hard, and looks like someone who's cranked the "sharpen" filter on Photoshop way, way too unnaturally high. As you pointed out, it's so keen to sharpen things, it turned motion blur on the antenna into two distinct antennae (!). It's so keen to sharpen, it's actually misinterpreting the image. It's like it's trying way too hard to please - to look super-sharp - that it's actually going too far and doing the wrong thing. Leave the bokeh alone, don't "undo" motion blur, stop trying so damned hard to look the sharpest of the sharp, as it's driving the AI to error. But, ah, this is a subjective thing, so opinions will vary.

I've already done a few video upscales with a different method. Topaz also have the Gigapixel AI software, which can be used to batch upscale pictures. So I extract video frames as png images using fmpeg and upscale them in Gigapixel AI. Then I again use ffmpeg to assemble the images into the upscaled video. It works really well and is reasonably fast with my Radeon RX 570 8GB taking 2-6 seconds upscaling frames from under 1280x720 to fullHD. The resulting files look better than all I've seen in this video, tho as someone else pointed out, you had CRF set to 33 in Video Enhance UI, which caused the resulting video to have a low bitrate. The higher the CRF is, the more compressed the video will be.

Thanks Chris. Had been looking to install some AI video upscaling software and hadn't heard of the free Waifu2x-Extension-GUI before. Will give it a go. Hopefully it runs on Win 7. Topaz AI requires win 10/11 but AVCLabs Video Enhancer A will run on Win 7 apparently. PS It's a Peacock butterfly, not a red admiral!

I have a couple of boat loads of old video tapes - 8mm and interlaced SD as well as old VHS tapes. I forsee a bleak future involving capturing and processing it all, whilst acquiring blood clots in my legs from immobility. (I just CAN'T walk away while it processes.) So I'll have you to thank when I croak from a pulmonary embolism! ; 0 (Actually, I'm immensely enthused - at the opportunity to bring old memories to vivid life! Thank you!!)

Thank you Chris for the real time estimation in the future. I have debated whether or not if AI Upscaling is even worth it long term due to the time to encode and the actual overall benefit besides some clarity. I can only think of a few reasons why I would upscale video with this type of software. #1 would be if the video quality was so poor and not interlaced and there are no sources for higher quality videos, I have done that with some old westerns and with the right settings (1 full day of encoding or more...), the picture quality is remarkable. Although faces still kinda look warped similar to Dall E's early versions. #2 if it was a business related video that needed to be enhanced. AI Upscaling can tell the difference between a face and a rock and whatnot. Don't expect miracles, if you convert 240p to 8k (I know it's silly, but go with it), it will not look normal whatsoever. But do it anyway...it's a lot of fun. I might play with Waifu in the future, but I'm still running a GTX 970 and my card hates me for all this upscaling....

I would just like to say that I found (on a much earlier version of Topaz Enhancer AI) that the suggested settings were literally *never* the best ones in any of the videos I used it on. I was using it on mostly impossible-to-find music videos and tv shows originally from VHS, and it took maybe a couple days of experimentation to get results that didn't have a lot of major-to-minor artifacting, or that ended up with less sharp results. I can tell by the UI here that they've changed a lot since then, so maybe that has changed.

Very interesting. You mention about being able to do this in real time at the end, the Nvidia shield claims to be able to do this already though only from 720p up to 4K so I guess lower start resolutions can’t be to far away.

the ai can't recover actual detail, the information for that just isn't there. it makes up detail that looks plausible. technique like this might be useful in some ways maybe but if you're thinking of using video enhanced in this way as some kind of legal evidence, i expect there would be problems with that

@@richard_d_bird You can recover actual detail using multiple image superresolution technique. If you have the same subject but it's moving, you can gain sub-pixel data. I don't see that Waifu2x does this, any of their supplied algorithms, but Topaz absolutely does. Unfortunately then it's the question of whether you really trust the outcome. It's generally a problem with image processing techniques, since they all produce artefacts, many of which can even look plausible, and AI turns up this problem to 11, since it's not even provable how it arrived at the outcome, what is hallucinated and what is actual source data. But it is sometimes also not such a big problem. You apprehend the suspect, and then use other means to see whether they are or aren't the culprit. Maybe there's an eyewitness, maybe there's tracking data demonstrating their movement. Then you have CCTV showing that there was only one person at the scene, that it couldn't have been someone else, and that's enough. But yeah catching people is expensive, even if you did have genuine HD footage. What about the DVR that runs the CCTV, they aren't particularly kind to the image either, and video compression can produce plausible looking but wrong detail even at higher quality grades.
