@lynne@pars.ee I'm not sure what "keep the HDR" means, but for my immediate needs I've got ~150 GB of 4k HDR videos synced between my phone and my computer.

I think that for the purposes of viewing on a phone or computer screen, I could downsample to 1080p or 720p and possibly a higher compression ratio to cut the space requirements down by like 75% and free up over 100GB of space.

I'm thinking of setting up a pipeline where the high quality videos go onto my local server, which then transcodes them and dumps them into a folder that gets synced back to the phone, so the originals live on my server and I still have effectively perceptually equivalent videos on my devices. The biggest sticking point has been this washing out of colors.

As long as removing the HDR gives me something that's in the right ballpark, I think I'll be happy.
