Week 7: Nuke Compositing

Original footage in Nuke:

Key light:

This proved very simple to use with very little problems resulting form the limited lighting from the filing process. the only problem is the small amount of blue left from the blue screen. Seeing as it is cotton wool and very fluffy it will be difficult to remove the colour without feathering away all the remaining detail. I have yet to decided on a back ground so I will address this again when I have the back plate sitting on a background. 

Camera tracker: 

This was a very important step as the last part of my animation didn't track with the camera. Once the girl stays still she isn't animated to stay with the camera so slides across the plate. So I camera tracked from the point when she needs to stay still onwards.

This camera tracker animation was then transferred to animation and I could see how she sat on the plate. The part of the plate that I tracked disappears off view as the camera pans up resulting in the girl overing in the bottom part of the frame.

To counter act this I created a second transform node and added extra animation to smoothly move her off the screen in accordance with the camera move.

This animation was then added to the animation filling in the line animation and render out so that the animation can then be placed again in front of the plate without any tracking necessary.

Nuke basic render and comp:

This is a basic render form Nuke with a back ground added behind the plate (this is just a simple image which needs to be tracked to the camera) and the animation.

I have now worked with Nuke for my own work and find it very useful for this technical aspect of the compositing process. I am however going to use After Effects for the next stages of the compositing as I feel that After Effects is more suited to my needs and I am far more comfortable in After Effects in order to experiment. In regards to my future career I will most likely be using After Effects more than Nuke and having now covered the Nuke basics I can enter the software again and develop my skills when needed.
