This can be in app form, such as Stop Motion Studio or software downloaded onto a desktop or laptop. You will need to bear in mind how you will take the photos for your video; if it is on your phone then you will need to download the software straight onto this device. The software will help you create a professional outcome by allowing you to extend certain frames, add sounds and transition effects.
You will need somewhere that has a white or at least a plain background so that you can manipulate it to your needs.
This will help to keep your shots steady so that the movement is focused on your characters and words rather than on your background.
Although light is normally our friend, when filming it becomes the sworn enemy. Rather than relying purely on natural light or artificial lights from above try and use lamps that you can control and move in relation to your shots. This will help you to stop any shadows appearing (unless of course it is part of your creative image).
Take lots of photos. The end product will look far more realistic if you capture the intricacies of movement, such as the process of bending down to pick something up. So instead of taking two snapshots, one bending down and one standing up, take 6-8 snapshots of the character going to bend down and then straightening up again.
