Camera tracking

During this lesson we followed a video tutorial by Gareth on importing a 3D object into a recording.

To begin I opened up Adobe AfterEffects to import the provided video, all I need to do is click and drag to the main screen and start. Screen Shot 2016-01-11 at 12.23.50.png

The next step is to select the ‘track camera’ in the animation options, this will bring up various points on the video, these points will allow you select a specific area which follows the video path.

The next step is to select ‘Create solid and Camera’ by right clicking on the target, doing this will bring up a square in which the model will be positioned. The square should be minimised so the model doesn’t come out too big for the video, you can see if it tracks well by playing the video.   Screen Shot 2016-01-11 at 12.30.42.png

The square will need to be exported to CINEMA 4D via the exporter, this will give you the C4D file, once opened the square will appear, it is important not to move the camera around as it might mess up the video. Screen Shot 2016-01-11 at 12.31.32.png

Select a model to use and copy/paste it to the window with the square. Screen Shot 2016-01-11 at 12.35.34.png

The model must then be positioned correctly on top of the square, once this step is done the square can be deleted. The model must be minimised appropriately to allow for the model room in the video.

Once all of this is completed it should be ready to export, it is important to remember to turn on the alpha channel in the render setting and to save all of the .tip files to a separate folder.

The model can now be imported in to AfterEffects, once the square is hidden and the frame rate changed to match  the video should render out smoothly.
