ONE CLOCK

One script in three aspects, playing in lockstep and hitting black on the same frame.

Master 69s1920×108030 fps -18.2 LUFS-3.2 dBTP sha f02d76a9028d

The numbers

Every figure, and the command that counted it

The build re-runs each command and refuses to render if a value has changed since the contract was signed.

QC

Every second of the film, on one sheet

One frame per second — the density this pipeline requires, because a single mid-frame grab has passed defects before.
