This software package is designed to work with the memory chip only. If you read below you will discover that the data on the memory chip is very fragmented. Once copied to the hard drive, the file is typically in a single sequence and so can be recovered with data carving. Many companies say they can recover GoPro Hero files but actually mean they can recover from a deleted hard drive. We are not are of any other package (except CnW Recovery) that will work with the original GoPro memory chip.
GoPro Studio has a feature where the SD memory card can be deleted automatically after copying to PC. Unfortunately there are reports of the copy not working correctly, but the memory chip still being deleted. Fortunately GoPro Recovery will rescue users from this problem. Just make sure that the card is not written to or used before a full receovery is made.
A MP4 style video file has three main elements, ftyp, moov, and mdat. Ftyp is a simple header that contains a small amount of fixed information. Moov contains amongst other elements, pointers to every frame in the video. Mdat is the video stream.
When a recording is started the length is obviously unknown. It could be a few seconds or several minutes. At this point some cameras start a ftyp-moov atom, and others store it in memory. The the video is written in the mdat atom. However, GoPro Hero 3 and 4 cameras can store a low resolution file (.lvr) as well as the standard MP4. These are stored in blocks, physically interleaved. This there may be 256 sectors of low resolution, followed by approx 4096 sectors of high resolution. The blocks are puer data streams with no nice headers and reconstruction is not simple. The GoProRecovery program has to analyse the contents of each possible block in order to determine if is correct. An added complication can be still JPEGs embedded in this data stream - which can include a simple thumbnail photo. This type of file structure means that GoPro and simple data carving does not work.
“I downloaded the recovery program and tested it on my deleted SD card. It found all my files and restored them perfectly!”
“Thank you so much! This is the 7th bit of software I have tried to recover a deleted mp4 file from a gopro hero4 black SD card. One bit of software couldn’t do it at all, 5 recovered a file that was unplayable, only goprorecovery recovered a useable file. I’m very grateful indeed for the work you have done on this software.”
“They have found a solution where no other software has helped”.
“The tool is working perfectly, I recovered 58 videos”
“This did the job! It recovered all needed shots! Huge thanks!”
