GOPRO_VIDEO_EXTRACTOR
Find out what your video actually contains. Inspect its streams, verify its structure, and put GPS and IMU telemetry in the spotlight.

File & camera
Video overview
GPS telemetry
Awaiting fileGPS fixes and precision are reported only when stored in the file. Coordinate presence alone does not establish a reliable fix.
IMU · motion sensors
Awaiting fileValues use the file’s scale and units. Axis labels follow recorded metadata; chart points are a bounded preview, while statistics use all decoded samples.
Streams & packet tables

Inspection coverage
Structural validation cannot prove that every compressed video frame decodes correctly.
Container & metadata inventory
Box offsets are absolute file bytes. GPMF entries include unknown keys so additional recorded data remains visible.

What does this tool check?
MP4 and QuickTime MOV inspection reads container boxes, track headers, codecs, dimensions, timing and sample tables. Indexed GoPro GPMF packets are checked for record boundaries and decoded to reveal GPS, acceleration, gyroscope and other sensor measurements. The report separates detected errors, data-quality warnings and unsupported checks.
Edited or transcoded videos may have lost their telemetry. Missing GPS or IMU data does not by itself mean the video is corrupt. This inspector does not repair files or certify every codec. Fragmented MP4 and encrypted tracks are identified but are not fully validated.
