Tell me the best settings

[shuterr]

I want to improve an old family video. I don't understand the settings very well, help me with advice, what parameters can I set to get the best video quality at the output?

I'd say:

• Mode: Filter (Upscaling)
• Filter: RealESRGAN
• Model: realesrgan-plus

Then in custom options, add:

• option: crf, value: 20
• option: preset, value: slow
