How to record a good video:

Clean your phone lens to remove any smudges
The best lighting source is the sun. Natural lighting looks great in almost every instance. Face yourself toward a window for great natural light, but never have the window behind you or you will be back lit and appear as a silhouette.
Position your phone in a horizontal frame with your face clearly visible. If someone is helping you film, ask them to position you in the center of the frame with your face and shoulders clearly visible
Do not use zoom when recording the video. Instead, ask the person helping you to come closer.
Aim for a 2-3 minute Make sure that you record in a quiet space with no background noise like passing traffic or working house appliances. Let the video run for 3 seconds before you start speaking and allow for it to run 3 seconds after you finish, before you stop recording. Once you record the video, check the quality of the sound to make sure that your speech is loud and clear
