All workspaces in Watchity have their own storage space in the cloud. When a Live Broadcast is finished, video files (.mp4) are generated for each of the contributions, whether mobile or broadcast, and another file is generated for the final production.
You will find all these files by accessing the "Original videos" in the configuration of your Live Broadcast. However, if you wish, you can also store them in the memory of your mobile phone. Select this option from the App settings.
