Piracy: ꜱᴀɪʟ ᴛʜᴇ ʜɪɢʜ ꜱᴇᴀꜱ

I'm getting a tad frustrated with the movies that get downloaded by my radarr setup. Mostly its the letterboxing being encoded in the file which on an ultrawide results in a full black border. Also just shoddy quality even on huge files.

With anime there is seadex and some reviewers here and there that give opinions on the best release to grab, but is there something like that for movies or is there only trash guides? One of the things that I've seen in anime reviews is that sometimes the bluray is plain old worse quality compared to the streaming platforms. Does anyone know of places where that gets noted?

Should I just download the largest file and get hardware encode and decode supporting gpu? Will I have encryption problems if I self encode from disk rips instead of using media player ready files?
