Lossless is lossless. But I shudder to imagine the file size of a 2 hour 13 channel 192/24 flac soundtrack.

However I notice a critical oversight on your part. You have assumed a channel depth of merely 8 bits when the minimum for a decent workflow is 12. Thus rather than 3.9 TiB (ie 4.3 TB) we arrive at 5.9 TiB.

Of course a modern feature length film is likely closer to 2.5 hours (7.3 TiB). Lossless HEVC should get that down closer to 2.5 TiB. At approximately 290 MiB per second that's going to demand dropping an SSD in the mail as the only practical method of distribution and playback.

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.
