I spend about one week making this stop motion video for my 5 year old daughter a whole ago. I hope you like it!
The technique I used to create this video is called stop-motion. Basically I took a photo and moved the lego a little bit and then too another photo and so on.
The tricky thing is to keep the lighting consistent. But with Adobe After Affects you can magic. Using an interpolation and anti flicker plugin you can smooth out the process.
Enjoy!
