Trying to fix my GoPro's crash footage, please help!

the perl script can make the video playable in vlc.

what is your bike a 250cc 2-stroke? you pull out of the garage, leave the paddock, enter the track, do 2 laps missing most apexes and getting passed by other riders. the video ends as you enter the front stretch the second time. no crash.

LOL, no its a GSXR750. Warmup lap is always slow, then there was a crash a few corners before the main straight, so I was just cruising around until the yellow flag was gone.

Was that the whole 704mb video? Or just the 1.2mb file?
No crash at the end?

Charlesbusa, can you upload a short, known-good, file from the same device.
It often helps when analyzing the bad file to have something to compare it to.

here's a short clip, http://www.fileswap.com/dl/MQigNrd4Ig/GOPR0002.MP4.html

didn't know a 4 stroke 750 could turn 15k rpm now, thought it was an f250. my old kz750 based bike could only turn 9k.

the 740mb file - sorry what lap did your crash happen on? on the second lap i can see the yellow flag come out and a rider down on your right a couple turns before the main straight. the video ends shortly after that as you enter the straight.

here's the last 30 seconds of the file at a low enough bitrate to post here.

Hey thanks a ton for your help!!

Sucks that the crash isn't there. I think it happened about 15 seconds later. I guess it takes the camera that long to actually write the video to the SD card. Probably was in the camera's RAM or something.


Yeah, 600s and 750s rev really high these days!

n.p.

t'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.
