[Request] Any Guides to FFMPEG, Transcoding, Codecs, and Metadata? (leminal.space)

I have a collection of about ~110 4K Blu-Ray movies that I've ripped and I want to take the time to compress and store them for use on a future Jellyfin server.

I know some very basics about ffmpeg and general codec information, but I have a very specific set of goals in mind I'm hoping someone could point me in the right direction with:

Smaller file size (obviously)
Image quality good enough that I cannot spot the difference, even on a high-end TV or projector
Preserved audio
Preserved HDR metadata

In a perfect world, I would love to be able to convert the proprietary HDR into an open standard, and the Dolby Atmos audio into an open standard, but a good compromise is this.

Assuming that I have the hardware necessary to do the initial encoding, and my server will be powerful enough for transcoding in that format, any tips or pointers?

Are those your own blurays? Then share them before compressing.

Transcoding is hard. There is no way that your transcoding settings are going to be a one size fits all. I am currently encoding the famous iKaos Dragonball release and I did 48 samples before deciding what configuration to use.

You are better off downloading stuff from torrent, especially for newer media. You'll find a community that put 100x your time collectively on transcoding. That will also save from your tremendous electricity costs.

Also look into vmaf for quality metrics. Consider that switching to uncompressed 1080 might bring you close to your goal with very very low effort.

Btw, can you share the title list?

yeah, I would redownload all of those instead of transcoding. They are all available with very good encodes publicly
