Adding Special Effects

In order to create the portal we used an ‘After Effects’ program and have imported the footage from the section where the portal is needed. Firstly, we made a black mask in a new layer and then with the pen tool we created a black circle over the top of the video footage. We used a tool called feathering in order to blur the edges into the background. We then put an effect onto another layer called the "twirl" to give the portal a moving effect. We then added advance lightening onto a new layer and looked closely into controls to create that particular effect. After that,  we duplicated this layer 12 times and changed the effect controls for each  of them to give a variation. Then we used the blending tool to blend the light colours together. We then reduced the opacity to 50% which would make the lighting less bright and finally we used another mask in order to create a circle in the centre of the portal.
