A full video's duration depends on its script, narration, slides, scenes, and pacing. A generated video clip has its own duration control.
Set a target for a full video
Open a workflow such as Script to video.
Write the target length in your request to the assistant, such as “Write a 60-second product launch script.”
Review the script and ask the assistant to shorten or expand it.
Review the pacing before clicking Continue.
Set a generated clip duration
In Prompt to video clip, choose from the durations shown in the workflow before clicking Generate video. Available durations can depend on the selected quality and generation options.
Tips
Use fewer words and scenes for a shorter result.
Preview narration after changing voice speed or script length.
Check the estimated credit cost before generating a longer clip.
