Gyroflow workflow

  1. Import the Video and Lens profile into Gyroflow
  2. Select the correct gyro orientation and Z-Rotation (you can also use right click and 'guess IMU orientation').
  3. Internal BMPCC gyro: add 1 manual syncpoint with 0ms offset.
  4. external Logger: press auto sync
  5. Export the Video to your preferred format. For exporting BRAW the Gyroflow OpenFX plugin for Davinci is needed.
