GoPro HERO4 Session for Skydiving

Posted by Mark Kirschenbaum on

(Photo from GoPro Bomb Squad Like them!) Good With its 1.5" cube form-factor and 50% smaller it's great for skydivers worried about snag hazards. The new mounts and one button recording make it a good camera for the weekend warrior.

I just learned something tonight after wondering what where those LRV and THM files on my GOPRO HERO3.  Turns out the THM is just a JPG used in the future as a thumbnail for the video and the LRV is a super low res version of the video (432x240). I'm assuming the latter is for playback via wifi or simply as the streaming buffer when the smartphone is used as control. If you want to see this, just rename the THM to jpg and the LRV to MP4.   It's also kinda neat/freaky that each MP4 has your camera's serial...
