Description

Thank you for this awesome project!! ❤️

The Problem

As the documentation states Gyroflow currently always exports in the same framerate as the source file.

This is fine by default, but a lot of devices struggle to even play back videos at 4k120, which can be recorded f.ex. by the DJI 03 Air Unit.

Proposed Solution

Gyroflow is (in my experience) already exceptionally good at integrating with GPU encoders. It would be great if an option to specify the target framerate could be added to Gyroflow, which also works with GPU encoders (if they support that).

Thx!
