Speaking of 2160p. What’s the recommended disc size for burning 4k?
4,7gb
Are you sure? When burning the Despecialized ISOs (with the menus), I needed discs that were 25GB or higher.
I think he might be “yanking your chain”…
05-Star.Wars.4K77.2160p.UHD.DNR.35mm.x265-v1.0.mkv is 48.3 GB (51,888,898,602 bytes) in size. That will not fit on a BD50, so you would be looking at something like a triple layered BD100.
BUT, it’s not as simple as a size of disc - to make the ISO you need to author a build a UHD 4K compliant Blu-ray, which this source video will not be. I’m not aware of anyone working on such a thing.
Forget burning it to disc, and instead pick up a high quality, fast USB stick (64GB). That will be your best option at present.
