What type of visual indication is given when a transition is ready to be rendered?

When a transition is ready to be rendered, a red line above the transition occurs in video editing software like Adobe Premiere Pro. This visual cue indicates that the footage requires rendering to ensure smooth playback and to avoid any performance issues. In the context of the software's timeline, red signifies that the effects or transitions applied may not play back in real-time and could cause stuttering or dropped frames during playback.

The green line generally indicates that the clip has been fully rendered and can be played back smoothly without any performance hindrance. A yellow line indicates that the section is still being processed but may playback in a lower quality or with some potential for dropped frames. No indication at all would suggest that there is no need for rendering, meaning the clips are set up correctly for optimal playback. Understanding these color codes is crucial for efficiently managing project timelines and ensuring that editing workflows are executed seamlessly.
