Basic fast turnaround DIY video making
Use your phone to start, shoot in well lit area out of wind. Use any basic video editing app to top and tail. Then move on to external mic with fluffy wind protection plugged into phone. This should get you through your first 20 videos.
Think about background noise and light when starting. Do not frame for "interesting" video background.
IMPORTANT: Don't listen to the "PROS" till you get past this stage.
