Previewing and Rendering Transitions
Many transitions can play back in real time, depending on your system and the transition
you’re applying. Those that can’t need to be rendered. Rendering is the process of
combining your video and audio with the applied effects, such as transitions or filters,
one frame at a time. The result is a new file, called a render file, that can be played back
in real time. The render bar, above the ruler in the Timeline, indicates the render status
of all transitions you’ve edited into your sequence (as well as other items in your sequence).
Render bar
The render bar has two regions, one for video and the other for audio. Because you may
have audio transitions that need to be rendered associated with sections of video that
don’t need rendering, audio and video are kept separate.
• Upper region: Indicates the presence and render status of video effect items.
• Lower region: Indicates the presence and render status of audio effect items.
The lower area indicates
the render status of
audio items.
The upper area indicates
the render status of
video items.
Determining the Render Status of Transitions
Colors in the render bar above items indicate whether the items need to be rendered.
Items that don’t need to be rendered have dark gray bars above them. For more
information about real-time effects, see
“Using RT Extreme.” For more information on
rendering, see “Rendering and Video Processing Settings.”
