What these are for

These answer the questions that come up around an edit rather than during one: what bitrate to target, what a timecode works out to, whether a 4K project will fit on a drive, what the export settings should be, and what to charge for the job. They are calculators and reference tools — nothing here processes a file, and nothing needs one.

Before you shootStorage and bitrate maths, so you find out a card is too small before the day rather than during it.
Before you exportExport settings and aspect-ratio maths, which is where most avoidable quality loss is decided.
While you workTimecode arithmetic, colour conversion and SRT offsets — the small conversions that otherwise interrupt an edit.
Around the jobA pricing calculator and an editing checklist, for the parts of freelance work that are not editing.
