AviSynth equivalent of the Super-Resolution technique in Adobe Photoshop?

Is there any AviSynth equivalent of the Super-Resolution technique in Adobe Photoshop shown in the video below?

The trick of this method is that he's using 20 images to produce one. For video, how are you going to have 20 versions of the video? It also gives a mess with motions so that's not good for videos.

The minimum requirement to even begin is alignment. Image stacking + alignment usually isn't possible in avisynth alone for general use cases , but you can use other programs to do the alignment then do some operations in avisynth if you wanted to For video, the alignment is usually done with motion tracking (again , not an avisynth - friendly operation) . But video has a host of other potential issues than photography for temporal SR - motion blur, compression artifacts, lens distortions , rolling shutter, moving targets, moving camera, angles of shots, long GOP compression (adjacent p,b frames are usually worse in quality, compared to photography which is analgous to all I frame), and you actually pollute the SNR unless you are very selective with frames. But it does work in very very selective cases for video . This is all discussed in other threads

You would need to use mvtools where you can replace normal frames with motion compensated frames from previous to current frame, and use this as a clip. You could create a second motion compensated clip using forward vectors. You can then use rgtools repair, mode=12 for example, and 'repair' the original clip using the back vectors created compensated frame and create a second clip with repaired original frame against the forward vector motion compensated frame. You then do a last repair of the original clip using the second clip. For using mvtools, you use pixel method not block method, which can result in nasty artifacts. You could resolve those in the original source compensated clips with the occlusion mask from framerateconverter. It might be quite slow though, and repair of rgtools hasn't got AVX2 etc yet (it's fast anyway, but potential improvement is there). Maybe only the back compensated frame would be useful. If this is the case you make the compensated frame, occlusion mask it, repair the original frame with it using mode 12 or whatever best suits. You could always make both the forward and back frames, occlusion mask them, average them, merge them with the original frame, and then repair the merged frame using the averaged frame and the original frame from this.

You've asked this same question before. The last time you asked it: Since absolutely nothing has changed since then, I'll provide a link to the answer I gave to you in that thread:

implement SRGAN urself if u wanna "real" super resolution

Ah... Super Resolution..... :) It all begins with a good quality source file. My source files are 1392x1032. Then, I reduce them (yes, reduce) to 1024x768. Why? Because a heavy script with removedirt(), Gammac(), stabilizing and degraining etc runs like a train (18fps) when the size from the source file is limited to W=1024 pixels. Then, I upscale to full HD and do some sharpening on the full HD file. I know, I know. It's against all rules :D But it works and the results are very acceptable. Source file: 1972 fuji single-8 film. Unsharp frame to test sharpening. Full HD result: stabilized-cropped-sharpened etc...(reduced to show here)

As always, I am in awe of your work. Another fabulous result!

Yes, really fabulous! @videoFred Can you post your source file and AviSynth script?

Another perfect result, Fred... one more (as always with you). Bravo !
