Corrupted Drone MP4 Won't Play: Fixing D-Log Clips After a Crash or Power Loss
A drone MP4 that won't play after a crash or power loss is usually missing its moov atom — the index a player needs — not its actual video. Drones write that index last, when recording closes cleanly, so a dead battery, crash, or pulled card leaves an unfinalized, unplayable file with all the frames intact. The fix is video repair, not recovery: rebuild the index using a healthy reference clip from the same drone and settings. This guide explains the moov atom, why D-Log/H.265 settings matter, and the repair workflow.
