Record playback-speed changes when presenting a thermal clip, and keep them separate from claims about the event’s actual duration. Slow playback can help a reviewer inspect available frames, but cannot establish new captured information.
Separate three time records
| Time record | Question to resolve |
|---|---|
| Capture timeline | What does the original file and documented recording method establish? |
| Edited timeline | Were sections cut, joined or retimed? |
| Playback setting | Is the reviewer watching at normal speed or another setting? |
Keep the original output available and identify any presentation copy. If the original timing information is absent or uncertain, state that limitation. Do not infer a measured event duration solely from how long an edited or slow-motion presentation takes to play.
Avoid a frame-rate substitution
A file or player may report a nominal playback rate. Ask the supplier how that relates to newly captured thermal images and any timestamps. A display or export rate does not by itself establish the detector’s response or a continuous sequence of new observations.
The P20 Pro thermal graphic lists 25Hz refresh rate. This article does not verify slow-motion capture, synchronized timing or any recording metadata in its supplied application. It reports no playback or event-duration measurement.
Use the live-view and recorded-output guide for the rate definitions, and file-traceability guidance for edited copies. Ask Phonemax which original timing information the delivered recording functions retain before adopting a review method.
