FFMPEG commands for advanced enhanced image & video editing & conversion?

I'd like to learn some new commands for ffmpeg for converting .jpg or .png with antialiasing & dithering to make the output images as clean & smooth as possible for wallpaper sake.

I'd like to know how to upscale a 720p .mp4 to 4k .mp4 hevc h265 with enhancements to the output.

Like sharpening & antialiasing, because Topaz Video Ai seems to give some visual corruption the source didn't have. I hope ffmpeg can convert the video at higher fidelity.

I'd prefer to use directx shaders from the enhanced video renderer in the conversion, particularly 2-4x unsharp mask shader stacked.

Thanks
