Using storyboards and keyframes

A storyboard allows you to define basic settings for the recording of a simulation. These, e.g., include the resolution, framerate and the option of saving the recording to a video file.

You assign at least one keyframe to your storyboard (Defining a storyboard with keyframes). In a storyboard, you can combine multiple keyframes that then elapse in sequence. You can assign a camera position to each keyframe.

Keyframes with camera positions from 2D mode and 3D mode cannot be used together in a storyboard. The mode of the first camera position determines the mode that all further camera positions of a storyboard must have.

The successive camera positions allow you to specify the order of the camera positions used during simulation. The camera dwells on the keyframes for the dwell time specified. It moves between the keyframes on a linear guide, with a constant or gliding motion, for the transition time specified.

You are basically using keyframes as a “script" for the AVI recording. During the AVI recording, the keyframes elapse in the sequence specified in the Start time attribute. The recording begins with the first start time. It does not have to be the start time of the simulation. As soon as the AVI recording is started, the view switches to the camera position of the first keyframe.

You can also use keyframes without a camera position to blend between different network editor layouts. If a keyframe with no assigned camera position is between two keyframes with assigned camera positions, Vissim interpolates the intermediate camera positions for blending.

To record a video file, you must define at least one keyframe with a camera position and a dwell time and assign it to a storyboard.

You can perform the following functions during a simulation run:

• Editing attributes of keyframes (Defining a storyboard with keyframes)
• add new camera positions (Saving camera positions)
• Editing attributes of camera positions (Attributes of camera positions)
• Showing a preview of the movie in a window in simulation speed (Showing a preview of camera movement)

Tip: You can additionally read Storyboards like other network objects and base data from other Vissim *.inpx network files (Reading a network additionally).
