For indoors, I use this camera, which was originally a Gopro Hero 11 but I stripped it down
and put it into this case. And now it is 3x times lighter than the original, but still has the same
video quality and everything.
For outside, I use the Gopro Hero 11 Mini. It is lighter than the normal Hero 11 and still has
a battery (the first camera I mentioned doesn't have one). It uses the same sensor and
everything so the quality is equally good.
After the recording, I stabilize the footage in Gyroflow. This program takes the footage with gyro data, which
it uses to stabilize the video basically in 3D space. For more info, check out the official website
of the app.
The last step is all of the other post processing, color grading, editing etc. I use DaVinci
Resolve for that. It offers everything I would ever need for this last step of the whole
video process and it does it for free.
