is there a tuturial on how to create this type of effect

[Todd Kopriva]

For the simple color changes, the Change To COlor effect is a good place to start.

For the more complex results, just lots of basic motion tracking and layering of mattes and other region-specific adjustments.

Here are a couple of videos that show some basic techniques for applying effects with a constrained region in a moving image:

I’ve had very good results using Color Finesse in AE – I was able to change the color of jumpsuits on two workers in a chemical plant, and you would be hard pressed to tell there was any CC going on. Of course your results will vary depending on the footage, lighting, etc.

simple matter of rotoscoping, maybe some hue keying and then just correct the hues/color correct the shirts/mask, easy concept but quite tedious job!
