# PAGE_CHANGE_UNDECLARED

> A script changed the picture outside every cue, motion, loop and frame hook, so verify cannot mask it and may read it as a reveal.

A script changed the picture outside every cue, motion, loop and frame hook, so verify cannot mask it and may read it as a reveal.

This finding is an error, and DeckTalk judges it itself. `decktalk record` reports it when it records the pages, and `decktalk verify` when it measures the finished film and reads back each recording log.
Pass `--allow PAGE_CHANGE_UNDECLARED` to carry on past it, and `--fail-on` to choose which severity fails a run.

## What to do

Make the change in a cue's handler, draw it from a frame hook with a region, or declare it as a motion.
