For single frame grabs I use QuickTime player and press Copy on the frame I want. You can then paste the frame into Preview or any other photo editing app to save out the image. Agreed that doing hundreds would be a pain.
The quality of footage and shots from the GoPro’s are generally not that great though. Not on the low end ones anyway.
Does anyone have any sound problems from their GoPro’s? I thought my bike was rattling but I’ve narrowed the noise down to the springs underneath the GoPro buttons now. I only found that out by videoing a track walk and my footsteps caused the same “cable rattle” noise as the bike footage… since I don’t have any cables to rattle… I figured the noise was coming from somewhere else. I eliminated my helmet and chest mount. Then found that shaking the camera by hand it caused the same noises.
Once you hear it, GoPro videos are never the same.
Mine is the GoPro Hero.
