DV Info Net - Why many movies won't be available in 4K

Despite shooting in 4K, one of the post-production houses thought it was worth retaining the 4K master files, only retaining 2K masters.

Quote:

“As much as we’ve been producing in the 4K format, we didn’t store it because nobody thought we were ever going to use it! We would shoot in legitimate 4096 x 2160, produce in 4K but then archive in 2K. We lost everything, because no one anticipated that it was actually going to come.”
