Leaked DayZ Standalone footage appears to come from an early build

Could this be leaked footage of DayZ's standalone version? It looks like everyone's favorite zombie-survival game, all right, but with an interestingly candy-colored inventory screen, among other features.

While this very well could be DayZ Standalone, which is in closed alpha testing , the YouTube commenters are probably correct in guessing that it's an older build. The reworked inventory system looks to still be in a nascent stage, and some of the character animations look awfully stiff. Knots describes the build as "terribly optimized"—it's likely this wasn't intended for eyes outside of the initial testing team.
