Working with 3D layers

Using this video made by a drone we learnt how to add various effects, including decay and fire.

Firstly we had to add the clip into the main composition, after wards I had to click on the anchor tool(besides the camera in the tool section) to drag the anchor in the clip downwards.

We then inserted a ground decay object but we had to make it blend into the clip. To do this we had to render its track points in effects control, after that many small colourful symbols appeared .

The next step was to pick one of them and right click them to create a null, then rotate the z axis to make it lay flat on the earth then blend it by playing around with the saturation and hue's.

To create the fire effect , we inserted a clip of a fire into the main composition, then made it 3D and played around with its axis.

After we aligned it with a null object and then changed the saturation and hue of the fire to make it blend and seem more realistic.

 To change the drone set up to a more suitable frame, we had to change the composition settings to 1280/720 frame and in the effects settings we had to use 'optics compensation.
