The first option is to go to the app’s main menu and select “videos.” From here, you can select all of the videos that you want to delete and press “delete.” If you want to delete a specific video, you can do so by selecting it from the list and pressing “delete.” If you want to keep a copy of a specific video for later use, you can do so by selecting it and pressing “copy.” Finally, if you just want to hide a video from view on your device, you can do so by selecting it and pressing “hide.” ..
