You can control how long a scene or element goes!
Hover on the timeline and you’ll see a white vertical bar. Click on it and drag outward to add duration, and drag inward (toward the left) to shorten the duration. You can adjust the duration of a Caption element (upper tab) or the Background element (lower tab).
Be mindful of how long your total video is! Your social media video wants to be snippy and eye-catching so it can fit in with all of its friends in the internet playground :)
Also, Biteable Pro is very new, so we'd really appreciate your feedback going forward! Please let us know what you think here! Your insight helps us know which features we need to prioritize.
