Bareilly LAB_ch1_20260804081507_20260804091507.asf → channel 1, started 2026-08-04 08:15:07. We parse that YYYYMMDDHHMMSS stamp as the clip’s start time, then for any frame we compute its true time as start + (frame offset in seconds) and burn it into the header banner. So a detection 90 s into CAM1 is stamped 08:16:37 — matching the original camera clock exactly across all six reports.
