Low resolution web-videos and scaling (fullscreen, 2x, 1.5x, 0.75x), without superResolution
- Scaling low resolution to fullscreen to view on a monitor should probably only be considered if the source is reasonably good. In this case to upscale 720p to 1080p, you just need a sharp resizer or a sharpening shader. Adding noise/grain might help if the source lacks it.
- When the source has visible artifacts at 100% zoom, the options are to try to reduce the artifacts or to view downscaled.
- Some artifacts can be treated effectively at low cost, but there isn't much built-in to mpc-hc/be to do this. Mpc-hc does offer a 3x3 gaussian blur shader (light spatial smoothing).
- In mpc-hc and mpc-be, only 200% and 50% zoom can be easily and directly applied in windowed mode. But often the desirable scaling would be 150% or 75%...
