IMO amethyst using handbrake solves this issue
YT videos are already well compressed and none of the transcoding makes them smaller at the same resolution. And yes, ffmpeg based solutions are much better
Times out in amethyst. YTDLnis rips YUGE videos from YT. I always have to handbrake them. Been having issues with the app lately. Over 200mb for a 10 min video.
