This is what I do:
1) I rip the video from Blu-ray to .mkv 1080p.
2) I used Hitpaw, de-noice and upscale the video clips to 2K resolution .mp4
3) I did fix videos manually by editing the frames, to extract the frames I used Filmora 13. this software also allows me to adjust brightness, color etc....
4) Last, I run 1 more time on Hitpaw video restoration, still on 2K resolution. I try to stay away from any A.I. model ... because it deforms things.. this one takes time...
After all that... I make the final video at 1080p with Filmora 13.
I always try to stay on fix bit rate, 30K.
