I want to know if it is posible to encode a video and also add the "fill the black bars" feature in the transcoding options.

I was having the same problem with a couple of anime chapters that i downloaded from another site. It seems that they were based on HorribleSubs release because i fixed the audio desync with the solution that you posted here. Thx for the info!
I'm using mpv + svp pro 4.2.0.122
