Look for humanPhotos for detailed inspection
An original photo keeps full-resolution detail and metadata in one file. Zoom and tiling aid review but cannot recover detail the sensor never recorded. Plan enough overlap to avoid gaps between photos. Complete DJI telemetry may support a constrained person-position estimate.
Video for temporal context
Adjacent frames help distinguish static objects and show changes in viewpoint. The app reviews samples at the selected interval; it does not promise to inspect every frame. A briefly visible subject may fall between samples. Strong compression or blur limits detail regardless of recording length.
Telemetry and timing
Photos may carry EXIF capture time and GPS. Video frame time uses available creation time plus frame offset; GPS is read from SRT. Review time should not be treated as proof of capture time when a reliable timestamp is absent. Preserve source files and check the device clock before deployment.
Run a comparison
Under controlled conditions, record the same area both ways. Compare subject detail, metadata, file sizes and review time on the actual computer. That trial describes that equipment and those conditions, not universal accuracy. Agree recording and archiving practices with the team.
