I’m using ffmpeg for some time, and I realy like it. It gives me full control of all specific actions and fine-tuning I wish to do. Recently I discovered and tried UniFab. Allthough I have a very fast system, an I7 with a 14700K cpu which can operate at around 5Ghz with its 20 cores (and a fast internal gpu: Intel UHD 770). I also have a nVidia GTX 1060 installed. Never the less UniFab still needs about 20hrs to upscale a lowres video.
I’ve done a test, and my findings is that ffmpeg does do the job better. I use following filter to upscale some low-res 4:3 video. The quality is much better than what UniFab can deliver me.
... -filter:v zscale=1440:1080:filter=spline36
But I saw unifab also does do video enhancement, but it also needs about 9 hours at my (fast system), which I don’t understand why so long. I googled and found that also nVidia supports video enhancement. Although my vga card is prety old, UniFab does do the most of it’s job via my nVidia card. So my question, can ffmpeg do the same as what unifab is doing? Is there some filter, which I don’t know about yet, that can enhance video?
I’m using a custom compiled ffMpeg, see following screenshot for its details.
