Check cinematic geography

Keep a rough map of the shot as the camera pulls back: glass and car in the action layer, crew around the set, city behind them, and the stunt repeated inside the crew’s monitors.

Use the nested screen as a checksum

The monitors are a demanding detail. They must show the stunt while the main frame still contains the set and crew, so the same event has to remain consistent at two scales.

Watch depth under speed

In the comparison, the pullback accelerates, depth compresses, the crew passes too quickly, and distant detail begins to break.

Do not judge the shot by the number of background objects. Check whether near, middle, and far layers change scale in a way one camera could plausibly produce.
