A quality check that runs beside the editor
Most mistakes in a motion graphic are invisible in the editor and obvious on a phone: a line of small print, a word that sits on a colour it cannot be read against, a button hidden under the player's own progress bar. A check now looks for them while you work.
Eleven things, checked as you go
Check sits in the top bar. It runs in the background while you edit and holds eleven rules: no dangerous flashing, text that stays on screen long enough to read, text big enough for a phone, text that stands out from what it sits on, clear of the player's controls, clear of where subtitles appear, exits that finish in time, no sudden jolts, one thing at a time, sound below clipping, and transparency.
Each finding says what it found in numbers — a line that is seventeen pixels high at 1080 lines, a contrast of 3.1 to 1 where the size needs 4.5 — how to fix it, and Show, which moves the playhead to the moment it happens.
Worth a look is not a wall
Results are Passed, Worth a look, or Needs attention, and a rule that does not apply to the project says so. Warnings never stop an export: the check is there to tell you, not to decide for you.
The one exception is flashing that could cause seizures. That is asked about before exporting, with Show me and a box to tick if the flashing is meant to be there.
The export says what the check found
The export panel carries one line with the check's result — ten passed, or three worth a look — and Open Check beside it, so the last look before a file is made includes it.
Why these eleven
They are the failures that are expensive to find later: a flash sequence that has to be recut, a caption that nobody could read, a call to action under the play bar. None of them need taste to judge, so a machine can say them plainly and leave the design to you.
