####GoPro Protune correction, timelapse assembling, fisheye removal, slow motion, 4:3 to 16:9 and motion blur in Linux OS - GoPro Studio for Linux - KDEnlive, FFMPEG, ImageMagick, Mencoder and Python!

GoPro Studio has been tremendously useful for GoPro users, but not all GoPro users can enjoy the tool, there is no GoPro Studio for Linux. So some users made their ways to emulate GoPro Studio on Linux.

This guide is more than GoPro Studio, is a must read guide for Linux and GoPro users.

The main features of GoPro Studio are:

• Convert and edit Protune footage and apply Protune effect.
• Convert 4:3 footage to 16:9
• Slow motion

1. AP_Button / storing a uint64_t in a uint32_t

2. In GPIO::pinMode - can't reset g->mode without changing from input to output at same time (oddity); the "already set" block needs more explanation

3. Is priority inheritance only a problem for recursive semaphores?
 - is 32-bit count a little bit of overkill?

4. thread_create() in SITL scheduler may attempt to free a->stack where that may be uninitialised

5. idle_adjustment += 0.5 => use a dt instead?

- Recalling the Kraken if it is NOT flying (perhaps in MAV_CMD_NAV_DELAY) should not cause it to take off!  It should instead cause it to disarm

- allowing misson extension with partial update seems a little *too* easy
 - what's resetting the mission count?

- No labelling of which servo pin is +/-/s

nav_delay attitude:
   No fabsf() is being done on the wrap_180 result; that function indicates it returns -180 to 180.

Check avoidance fail action on both Kraken and Porter
 - and all other avoidance parameters


Consider using sbus failsafe bit to determine if we have active RC control over the vehicle
