Selur's Little Message Board

I'm starting to get a reasonable feel for using the GUI Selur, it is starting to make sense to me now.
Searching for information on the various models on Github, etc is also helping me get a better handle on video upscaling as well.

I've got a project underway, upscaling a 720i DVD to 2880. I've deinterlaced the file, and are now playing with different filters. I'm running each one individually, rather than as just one big processing job.
I'm intending to adjust the colour, sharpen using CAS, upscale using Real-ESRGAN and interpolate from 30 to 60 fps using RIFE.
With the first go with the project, I adjusted the colour and sharpened before I upscaled and interpolated. I ended up with a nasty flicker towards the end of the file, that got worse as the video continued. I'm assuming I'd introduced a low level artifact that the upscaling or interpolation picked up on and reinforced/ magnified as the processing went on.

I'm having another crack at it, this time leaving the colour and sharpening work until after I've upscaled and interpolated.

Is there any rule of thumb for the sequence of using colour, sharpening, upscaling and interpolation filters, or is it really a case-by -case basis, depending on the file you are working with?

Also, I knoe Real-ESRGAN is slow to process. I'm using the ESRGAN x4 model, processing on a GTX1660 GPU. Currently processing at 0.05 fps . Are there any tips for getting the processing speed up? Beautiful results, but a long time to get them.

Please, read the 'Infos needed to fix&reproduce bugs,..'-sticky before you post about a problem.

1. yes
2. try this - TVAI v.4.2.2 = Proteus or IRIS

The default filter order is usually a good start, but depending on the source and filtering adjusting the filter order can make sense.

Better hardware which is faster and supports Tensor RT. (this way an engine file will be created which takes time, but the general processing will be faster)

Cu Selur

Thank you for that.

Thanks for that Selur.
Time to invest in a RTX GPU me thinks.
