Prepare your friend
Ask friend to view some of the messages you like the best.
Offer them time to think about what they want to say.
If they want more guidance, this structure may help:
O Only 10-20 seconds
M Memory or activity you share
E Plan exit line in advance.
Face should be about an arm's distance away from camera.
Point out where camera is or put a sticky dot there.
Hit the red button to start (and stop) recording.
For self recordings, tap white camera icon in upper right corner.
Of course, these aren’t hard and fast rules. A Friendclips video can be footage of a shared activity instead of a standard greeting, for example.
