We totally understand—it can be confusing when you select a video length like 20–30 seconds, but the generated output ends up being closer to 55 seconds or even over a minute.

You can shorten the video by editing the script and regenerating the voiceover inside the editor. Here's how:
Open your video in the Zebracat editor
Click the Voice tab on the left
Edit your script to make it shorter
Click Update Voice to regenerate a shorter version
