iPads are fantastic for filming and editing inside and outside the classroom. Holding the iPad while videoing can produce wobbly results. What you need is a simple stand to hold the iPad while filming, or taking photos – especially when doing stop frame animation.
We made some simple stands for our workshops from some timber offcuts. A piece of hardwood flooring 200mm x 90mm with a 10mm slot to hold iPad works well. The size and weight provides stability, and you can prop the stand front or back with a variety of objects to get different angles.
Obviously there are fancier iPad holders for tripods, but making your own might better suite your budget!
