Chroma key

How hard is to remove background from one footage? Yes, yes.. It’s really easy if you do it for (one) picture. A little bit of magic-wand in photoshop and that’s it! But what about video? You have 25 frames per second! That’s a lot of magic-wanding. If you do it that way, it’s called rotoscoping (therm used also for drawing over video). Other way is to record video in front of specially colored background (blue or green) and then in post production (premiere, after effects, etc.) you can remove background with not-so-much-pain.

I added a little bit of masking to give depth to video, and more realistic look.

Here is my example of composing one such short.
