A SaaS explainer works when it shows the product decision rather than decorating a feature list. Real screens and editable interface compositions can live together in one timeline.
Write the promise first
Open with the user problem and visible outcome. Keep each scene responsible for one decision or product moment.
Group complex UI locally
Use groups for browser windows, dashboards and notification systems. Keep ordinary footage, audio and simple text as direct layers when grouping would add no clarity.
Review representative frames
Check the opening, each scene transition, dense interface moments and the final call to action. Use a focused frame grid before rendering the complete video.
