Feature Request : Adding Sharpening To SSR #966

Open dotdebcli opened 2 years ago

dotdebcli commented 2 years ago

Should be possible and mayhap not too hard to add sharpening options? When for example downscaling, as not to lose too much detail and or making it so blurry that massive loss of quality incurs. OBS already has options available (Lancoz x32)

To give some idea of what, where and how. At time of writing minimal loss of quality incurs at about half of the resolution display, when downscaling. 8K downscaled > 4K > Minimal loss of quality (Without sharpening) If somehow sharpening was added, it should lower the loss of quality even further. That goes for quad to eight core cpus that require downscaling for more consistent frames.

Frame fluency sweet spot for quad to eight core cpus seems to be at about 1600x900 resolution downscaled from 8,7,6,5 and or 4 K resolutions. As to give some idea about frame fluency (0 loss of motion of frames) and an approximate on cpu power.
