Possible to rip UHD discs as SDR?

#1 Post by ombai » Fri Sep 29, 2023 12:47 pm

I want to make backups of my collection and also have files I can easily watch when I don’t have internet. For this use case I’m fine with 1080p and even some compression via handbrake. For my UHD films that came with standard Blu Ray copies I’m just going to rip those. But I have a few box sets (Indiana Jones comes to mind) that only have UHD discs. I really don’t need (nor really want) these MKV files to have the HDR layers embedded. Is it possible to rip them in SDR with makeMkv or is this not possible?

Thanks I’m advance for any info!

MakeMKV is going to rip what's there... If you want lower resolution, processing the result with, say, handbrake can give you lower resolution.

If you want Handbrake to output SDR, you can use the colorspace filter set to BT.709, which is the colorspace used on regular blu-rays and regular HDTV.

UHDs are generally in the BT.2020 colorspace.
