GoPro file types
The GoPro camera creates several types of file as listed below. GPR will recover them all after they have been deleted
MP4 - this the the standard video file - at high resolution
LRV - low resolution video. In most modes, a GoPro records both high and low resolution files. Typically one can use the video program VLC to view the .LRV video. If there are issues, then change the extension to .MP4
WAV - this is the audio file if recording with enhanced audio, Hero 6/7/8
JPG - Photos - this are ones taken by 'hand'
THM - Thumbnails. These are in fact jpgs, but generated by the camera. To view it may be necessary to chang ethe extension to .JPG
recover_xx.mp4. This is a recovered MP4 file
reconstruct_xx.mp4. This is a file where the header has been found, but was probably not finalised. This is forensic option only
build_xx.mp4. This a file where a fragment of video was found, but no header or finalisation. This is a forensic option only.
The
demo
program generates encrypted files that have extensions such as .demomp4, .demolrv. These can be decoded once a full licence has been purchased.
