1.2 million gigabytes ... doesn't seem all that radical. Bigger than my home storage, but only by 500 times. I also have RAID and remote backups with provable error protection.

I wonder where it comes from. I would guess that it's a few small works like software and games, and then a lot of high-res digital transfers of films, scans of 2-D work, and photos of sculptures and installations.
Some of it's 4K video I think.
For sure. I wouldn't be surprised if they had 8K scans of some things, too. I would be curious how much compression their archival system does on top of whatever original format was used.
FFV1 has been gaining popularity as an archival (lossless) video codec. It gets about 2:1 compression. I would guess that higher-res scans would compress better because neighboring pixels would look more similar, but I haven't seen any actual data supporting that. Lossless audio codecs like FLAC also get about 2:1 compression, so I'd use that as a rule of thumb for archival audio & video in general.
