GoPro removed autoexec from v.1.50 of the GoPro HERO4 Session. Some people have been asking us for this functionality again. Re-implementing autoexec would be a huge undertaking and therefore we looked for a different solution. After some digging, most of the functionality is available as part of the calibration routines. Simply create a 'cal.txt' file and place the lines: _tapp <test app command> for your script. For instance cal.txt to set usb mode to msc looks like: # HYPOXIC https://github.com/hypoxic/hero4-session...

Unfortunately there is no human readable settings information in the GoPro MP4 file.  However there are few bits that contain the camera's information. Hypoxic wrote a tool to extract the GoPro settings and the times of the highlight tags. This tool was made for the GoPro HERO4 but may work for older cameras. Leave feedback on HYPOXIC's Facebook page or git repository if you have suggestions.   For MAC OSx GoProInfo v. 0.0.5For PC GoProInfo v. 0.0.6 Based upon Bento4, the...

On the latest firmware if the battery is removed with the camera powered on, you may lose your WiFi settings. This will require you to pair the camera again with the GoPro App. Our recommendation is to not remove the battery if at all possible while the camera is powered on. If you do so, its best to make it a quick, assertive pull. We have also seen this sometimes when a customer formats via their computer. In the past this...

We spend a lot of time working on the interoperability between our products and GoPro Cameras. In doing this we uncover some features that may or may not make it into future products. Here are some of the bigger points: Multi Cam The camera's firmware enables multiple GoPro HERO4s to be synchronized (genlocked) to prevent inner-frame latency issues between cameras. This enables bullet-time and 360deg cubes to capture the exact same instant on all cameras. It also simplifies the post operations since...
