Here are a bunch of scripts that I created some time ago as a proof of concept that Betaflight blackbox gyro data can be converted to GoPro Metadata Format (GPMF) and embedded into a MP4 file that is shot with non-GoPro camera.

The goal of this is that the file thus produced can be used in ReelSteady GO to achieve image stabilization (similar to GoPro HyperSmooth functionality).

There is a discussion here which gives some basic idea how the scripts can be used.

These scripts are not a finished product and if one wants to use them he’ll have to dig in and modify them according to his needs.

Currently I don’t plan to develop this project any further but I’m placing it here so that anyone who finds it interesting can base his own work on it.

Currently the active branch of the project is https://github.com/Cleric-K/BlackboxToGPMF/tree/gui It is entirely developed by @attilafustos
