I know it may sound strange to a few. Topaz VEAI processes a video frame by frame, very much like a photography application would process a batch job image per image (picture per picture).
It remains my opinion that there is a lack of control on the output from VEAI. Sometimes you have over sharpening (extra blur), sometimes you would like to restore more detail…
This has pushed to turn to photography applications where you have more control on the settings and the output. I convert my video to a format with a constant frame rate and then export the footage to an image sequence.
I started with Topaz Denoise AI which produces interesting results on slightly blurry videos. DenoiseAI does sharpen, sometimes better than Topaz Sharpen AI (fewer monsters).
After playing around Topaz products, I tried competitors. DVDfab Photo Enhancer AI impressed me with its sharpen and denoise tools. The ‘sharpen’ feature produces smoother outputs than Topaz applications. Where Topaz produces monsters, DVDfab photo enhancer AI manages to sharpen an extra mile without producing a monster.
Moreover, the output generally produces less grain, providing a better picture quality.
But there are limits in batch capabilities and the editor/vendor does not seem to want to work on this.
It is my belief that the more control a user can have the better the result will be and the happier the user will feel.
Because every AI model is trained differently, I also recommend to look at the competition. Naming DVDfab Photo Enhancer AI was meant to be a constructive comment. A competitor may have a model which suits better certain types of sources because another model went through a different training path.
