Video Delivery Specs

Deliver motion content correctly across platforms: produce per-platform spec sheets, repurpose one master into every aspect ratio safely, handle captions and accessibility, and run a pre-delivery QC and collect-files pass before handover.

When to use

Use when exporting or delivering finished motion, when targeting multiple platforms from one master, when checking safe areas for UI-overlay platforms, when deciding caption strategy, or when packaging a project for handover/archive.

Decision tree — master strategy and spec path

Two judgments: what to build as the master so it survives every crop, and which delivery path each platform needs. Decide the master before animating — re-cropping after the fact is where deliveries break.

How many ratios does the brief's distribution need?
├─ One ratio only → animate native to that ratio; no spine needed.
└─ Multiple ratios → build a 16:9 master with a centre 1:1 "title-safe
    spine"; expect to RE-LAYOUT (not just crop) for 9:16.
