As I understand it, you're asking for these things, correct? **3D translational motion tracking and correction** Determine the spatial position of the camera in order to correct for panning motion....

> So generating a fractional frame would only require interpolating the motion, pan and zoom of the two closest neighboring frames and applying a global correction to one of them...

This issue has been reported for some hero 7 users, will look more into it.

That is no longer part of the codebase, since it was modified to make better mathematical sense

4 GB files can be concatenated through the process described here: https://gopro.github.io/labs/control/chapters/ Not sure if the results work with gyroflow though since I haven't tried yet

Still need to write a detailed reference for it, but have a look at: * https://github.com/ElvinC/gyroflow/blob/master/gyrolog.py#L1030 * https://github.com/ElvinC/gyroflow/blob/master/gyrolog.py#L152 * https://github.com/ElvinC/gyroflow/blob/master/examples/gyroflow_format_example.gcsv * https://github.com/ElvinC/gyroflow/issues/54 (coordinate system) the `.gcsv` "format" is the most...

There's some info about gyro orientation here: https://github.com/ElvinC/gyroflow/issues/54

Thanks for the bug report, could you give some info about which system/OS you're running?
