This section covers a variety of refinements that you can make in Ultra to put the finishing touches on a composited shot. These changes can make the difference between a scene that is merely effective and one that is truly convincing.

Correcting colors

Adding shadows and reflections

Defocusing a source

The following are changes you can make outside of Ultra to modify your video:

Matching mixed media: If the input clips are DV that were compressed, but the background was shot on film, the two sources may not match perfectly. Typically, the film footage looks too clean compared to the subject. Since there's no way to make the DV clip as clean as the film, you can compress the film clip in an NLE, such as Premiere Pro, using the same codec, or you can add noise using Adobe Premiere Pro.

Matching the audio to the virtual environment: In some situations, you may want to process the audio for a composited scene to make it sound like it was recorded in an environment similar to the virtual set in which the scene takes place. For example, if a scene is set in a large virtual cathedral, you may want to add some reverb to the actor's voice. You can also change the reverb and equalizer settings to simulate relative microphone distance between tight shots and wide shots. You may also want to mix in subtle appropriate ambient sound effects, such as street noise or wind in the trees. You cannot change the audio in Ultra. You can use an application such as Adobe Audition or Soundbooth.
