6 Common Video Corruption Scenarios & Errors We Resolve
From drone crash landings to unfinalized camera buffers, Prism repairs broken container structures at the bitstream layer.
Drone Mid-Air Crash & Sudden Battery Ejection
When a DJI drone loses battery power or crashes mid-recording, recording cuts off before writing the container index (MOOV atom). The resulting MP4/MOV has full file size but 0 duration and cannot open.
Windows Media Player Error 0xc00d36c4 & 0xc00d5212
Common Windows Media Player and Movies & TV app playback failures caused by missing codec initialization headers, damaged atom offsets, or unsupported elementary stream muxing.
QuickTime Error 2048: The file is not a movie file
Occurs on macOS when Apple QuickTime Player encounters a truncated MOV/MP4 header or missing ftyp branding signature following interrupted SD card transfers or abrupt ejects.
Audio & Video Desynchronization / Glitch Frames
Interrupted recordings or variable frame rate (VFR) recording can cause audio to drift several seconds ahead or behind video frames during playback.
GoPro Action Cam Power Cutoff & File Freezes
High-vibration action recording can dislodge camera batteries, resulting in unfinalized 4K/5.3K HEVC .MP4 files with frozen frames or black screens upon playback.
Dashcam & CCTV Surveillance Loop Crash
Continuous loop recording on dashcams (Nextbase, Garmin, VIOFO) frequently corrupts the final video segment during sudden vehicle accidents or power disconnects.
Lossless Bitstream Forensics vs. Generic Transcoding
Why direct stream carving preserves 100% of your camera's original resolution, HDR grading, and bitrate without quality loss.

Use the free trial to check whether the result fits your task. Here is what to look for when testing your own data.
-
Import corrupted video & inspect diagnostics
Import your damaged MP4, MOV, MKV, or AVI file. The bitstream forensics engine scans atom hierarchies, sample chunk offsets, and corruption severity within seconds.
-
Provide sample reference file (Untrunc)
For severely truncated files or unwritten MOOV atoms from camera power loss, select a working sample video from the same camera to reconstruct sample tables.
-
Preview 1-minute playable sample & test audio sync
Watch full video playback in the built-in player, test PTS/DTS audio delay alignment, and verify crisp frame clarity before exporting the full video.

Video Repair Tool: frequently asked questions
Why won't my video play even though the file size is large?
When a camera stops recording abruptly (due to a dead battery, crash, or memory card ejection), it writes the video frames into the media data area but fails to write the container index (MOOV atom) at the end. Without this index, standard video players cannot find the video frames or know the video length. Prism Video Repair scans the raw video frames and rebuilds the missing index so the video plays normally.
What is Advanced Sample Repair with a reference video?
If a video is severely damaged and its internal configuration parameters are unreadable, Advanced Sample Repair uses a healthy 'donor' video recorded on the same camera with identical resolution and frame rate. The engine extracts the camera's technical profile from the healthy file and applies it to rebuild the damaged file's index.
Does repairing the video reduce its visual quality?
No. Prism uses direct stream copying by default. It rebuilds the container index without re-compressing the video or audio streams, preserving the original camera resolution, bitrate, color grading, and audio fidelity.
Which camera brands and devices are supported?
Prism includes built-in profiles for DJI drones (Mavic, Mini, Air, Inspire), GoPro action cameras (Hero 8–13), Sony mirrorless cameras (A7S, FX3, A7 IV), Canon EOS cameras (R5, R6), Apple iPhones (ProRes, 4K HDR), Samsung Galaxy phones, and generic dashcam/CCTV loop recorders.
How does the Free Evaluation Trial work?
The free trial allows you to import your video files, perform a full container diagnostic scan, inspect detected video parameters, and watch a playable preview of the first 1 minute of the repaired video. Exporting the complete unwatermarked video file requires an active license.
Is my video uploaded to the internet during repair?
No. All video scanning, index rebuilding, and stream processing run locally on your computer. No video content is uploaded to external servers.
Can it fix videos with out-of-sync audio?
Yes. The Preview Step includes a real-time Audio Synchronization calibration slider (-2000ms to +2000ms) that allows you to correct audio delay before exporting the finalized video.
