Flowshutter is a custom camera remote. When used in conjunction with readily available hardware, this results in a flexible and reliable external camera motion logger for Gyroflow. It can provide precise synchronization of camera video recording and motion logger (betaflight/emuflight FC) recording.

It was designed to be used with the Gyroflow software to provide you one of the best open source video stabilization experiences.


  • "1-click" - start/stop (1) FC arm (2) camera recording at the same time
  • "Audio injection" - inject sync marker to the audio track for precise synchronization between video and gyro data
  • OLED display - show the device information and allow user to change settings without hacking the firmware code
  • OTA update - (WIP) update the firmware over the air

Supported Hardware

Currently we are working with a manufacturer that will produce flowshutter hardware. We will disclose more relevant information in the future.

At the same time you can try to DIY your own flowshutter hardware. I have two open sourced designs:

Compatible camera protocol/trigger mechanisms

  • Sony Multi-Terminal Port USB Protocol
  • Momentary Ground
  • 3.3V Schmitt Trigger
  • (WIP) 5V/12V Schmitt Trigger
  • (WIP) Sony LANC protocol
  • (WIP) HDMI CEC protocol

Check out our supported camera list for more details.

Compatible FC

  • Flowbox (highly recommended)
  • Modern FC with BMI270 gyro (recommended)
  • Any other FC that support CRSF protocol
