Uncompressed 4k video is ~5Gbps (3840 * 2160 * 3 * 24 * 8). A 2-hour movie clocks in at about 4.3TB. (3840 * 2160 * 3 * 24 * 60 * 60 * 2)

All that is 24fps.

That's without audio, which I assume you also want to be uncompressed.

TBF even as bloated as 48/24 FLAC is it's a rounding error at that point.

But FLAC is compressed. Don't forget 13 channels. Only the best! Probably 192 khz.

Even though op wrote "uncompressed" you should be able to deduce from context that they meant not lossy compressed.

If either lossless or uncompressed was reasonable in this instance, I would interpret it as such. Uncompressed video is completely bonkers of course. So is lossless. Shrug.
