How can deblend this ?

[Selur]

Could you take a look and tell me which encoding settings would work best?

Not really, since encoding settings are highly subjective I won't recommend more than use x265, x264 or one of the av1 encoders, use crf (or 'constant quality') and lower the value till the output size is too large for your taste. The defaults are usually a good starting point, but especially for animes, you can often use larger values.

Also, what would you recommend for cropping? I’d like to keep the original resolution but remove the black bars on the sides.

I would, if the input PAR isn't 1:1:

• crop
  
• tell Hybrid to adjust the PAR to 1:1
  
• tell the resizer to adjust the width instead of the height and set the height to the crop height.
  

otherwise I would just crop.

Could you recommend the best settings for this DVD source?

Will look at it after work,..
