So you might be wondering what start stop animation is .
Start stop animation is also called stop motion .So lets call it that.
So its quite simple. you take a picture ,move the item ,take another picture ,And repeat! Depending on the device you use,the playback will vary,so i cant help with that .sorry.
So you can do stop motion with anything but i think lego is best.
But that depends.
If you do stop motion you can find anything to stop motion with.
Do you do stop motion?
