I'm Ji , from RedPixl. I've spent years in DIT and post, and one thing never stopped stinging: a master gets bounced by a platform for something small and specific a wrong colour tag, loudness 0.5 LU off, a frame rate that was "close enough." You usually find out after the file's been rejected and the clock's already ticking.
Checkpoint QC answers one question before you hit send: does this file actually meet the spec you were given?
Point it at a master and it reads the real file codec, resolution, frame rate, chroma, bit depth, colour tags, timecode, audio layout, loudness and checks every value against the delivery spec you picked. Each rule passes, fails, or is flagged for manual review. Nothing is guessed.
Before you ship masters, make sure they pass the spec — not just that they look right. Checkpoint QC batch-checks a folder of clips against a delivery spec and reports pass/fail on resolution, frame rate, codec, chroma subsampling, bit depth, audio config, broadcast-safe levels, and file naming. Export a report to hand to the producer or client. Native macOS app. By a working DIT/colorist, who built it because delivery specs kept arriving as PDFs.
