How to Record your Readout 2021 Video from an iPhone/iPad
Click the camera app icon.
Cropping the video will make the size of the frame smaller. Do so by sliding the white border into the picture from any side. (Note: This is only advisable if you are trying to take something out of the frame. Otherwise cropping should not be utilized.)
Clicking on the movie strip area will cause the strip to be highlighted yellow. Use the white slider to delete scenes. This only can be done to the beginning and the end of the video. You cannot delete from the middle of the video using this tool.
