Most cameras include a setting to specify the rotation of the video (e.g. 180 degrees to flip the video upside down or 90 degrees to change orientation from landscape to portrait). It's best to use the camera's own settings to encode the video in the proper orientation.
However, if you're camera doesn't include a rotation setting, or doesn't support the industry-standard rotation metadata, you can ask Camio to perform the rotation by setting ffmpeg_segmentation_rotation_degrees in your CSV import.
The value specifies the degrees to rotate counterclockwise.
