# Changing the Start Frame and Duration of a Dynamic Camera

When you add a dynamic camera, it always appears at the first frame of the scene and covers a default length of 20 frames. If you need to make a dynamic camera effect last longer, you must modify the duration of the camera element in the Timeline window.

For example, if you want to link a zoom effect to a pan that is controlled by a peg, you should make the zoom effect last as long as the peg.

To modify the start/end frame and duration of a dynamic camera zoom, follow one of these steps.

To change the start/end frame of the camera:

1. Click the camera’s bar in the right panel of the Timeline window.

2. Drag the camera bar to the correct position in the Timeline window. You may want to use the zoom slider at the bottom of the Timeline window to see more or less of the Timeline.

| The thin red bar that appears in the Timeline window for all cameras indicates the duration of the camera’s recording time in the scene. The red bar for the active scene camera increases or decreases based on the duration of all visible elements in the scene. Even if the camera is dynamic for only a few frames (the length of the trackbar), it continues to record until the last frame where there is a visual element.

To change the duration of a camera effect:

1. Move the pointer to the end or the beginning of the camera bar in the right panel of the Timeline window.

2. Drag the boundary to the left or right to increase or decrease the length of the camera. A camera must always be at least two frames in length.
