Currently, you are not able to rotate a video while recording on the TORSH Talent mobile app. If you change the orientation of your device during recording, the video will have mixed orientation throughout the video, much like it would on your native Camera app.
Be sure to set your desired orientation of a video prior to recording. If you do forget to set your desired orientation, please read this article for more information on how to rotate a video once it has been uploaded to the platform.
