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?
Best tip I can give is to use a tool that’s made for this task, like Tdarr/FileFlows/Unmanic. They take care of all the complicated issues like encoders, ffmpeg parameters and parallel processing on multiple nodes, so you only have to handle the things you actually care about.
Unmanic is way easier to understand than Tdarr. I use it to transcode DVR recordings recorded using Plex and a HDHomeRun tuner. Digital TV uses MPEG2 which has pretty large file sizes.
