Unfortunately I crashed my GSXR750 at Texas World Speedway, but I have no injuries. The bike will need a lot of work, but I was filming when I crashed with a HD GoPro. During the crash, the Go Pro's battery cover popped open and the battery came out just enough to come off the contacts and lose power. Luckily the camera is fine, just put the battery back in and put the battery cover back on.
But since I never hit the stop recording button and the camera lost power while it was recording, the video isn't finished properly. This is the error message when Win Media Player tries to play it;
"Windows Media Player cannot play the file. The Player might not support the file type or might not support the codec that was used to compress the file."
Its an MP4 file, 720MB.
I googled for hours try to find fixes and everything seemed to be a dead end. I tried http://goprohacks.blogspot.com/p/how...rupted-or.html program to fix the MP4 file and I was able to start their program, input the file's name, enter the video type "ntscr3", enter the compensation value of 0 and this is the error message this program gave me;
"The system cannot find the path specified. 'pearl' is not recognized as an internal or external command, operable program or batch file."

Does anybody know how I can fix this MP4 file? I really would like to see the crash footage!
Thanks!
 
I'm no computer geek, but I have plenty of experience with digital cameras and Gopros. It's safe to say. You are shit out of luck. The fact that the battery fell out or you didn't stop the recording didn't complete the file. The file is not there. You can't fix a file that isn't. But, if you plug your camera or memory card into your computer and in your control panel you physically see the file. Then it's there. Window Vista does not support Mp4 files. Windows 7 does. I too had this problem before I updated to a new computer. Before then, the simplest thing to do is. Download Prism video file converter for free. From that point you can convert the Mp4 file to a wmv file or similar video file. Once you've done that you can view the file on your version of WindowsMediaplayer. Be sure not to delete the Mp4 file. For when you update your software or computer you'll wish you had it. It's a better quality file.
 
Vlc is a good one to try too. Problem he'll most likely have though. Vlc will most likely play the file very slowly until he converts it. Vlc plays video slower on my computer. But, maybe you won't have that problem.

I have the 64bit win 7.
Can't remember how to find out what version of win media player i have, but its pretty modern.

There definately a file, 003.mp4, and its 704mb.

I'll give those ideas a try. Keep the advice coming!

VLC player did not work.

The file needs to be fixed since the camera didn't have the chance to finish the file.

GoPro support came up empty as well, the only fix they have is the SOS feature which I didn't get...

The solution was to use index rewriting by recreating the missing moov atoms of the file. I used http://curx.free.fr/market/fixenV2.zip from this website
http://goprohacks.blogspot.com/p/how-to-restore-gopro-mp4-corrupted-or.html and it was able to fix my video. Unfortunately the crash was not written to the SD card by the time the battery became dislodged, so no crash footage for me. One guy explained,
"It's a common problem with long gop mp4. a single gop can be 300 frames or about 10 seconds, and losing the single i frame they correspond to loses all 10 seconds of video. so yeah the crash was probably in the cameras ram buffer and not written to the file yet when it lost power. "
