SaaS founders, indie hackers, and product marketers.
Starting inputs
Start with the product assets you already have
The workflow begins from concrete SaaS product material, not from a broad prompt about a category.
Use crisp UI states, before/after screens, or a dashboard moment as the visual anchor.
Trim the recording to the single feature path that should become motion.
Convert the launch note into a short story: problem, product moment, outcome.
Three-step workflow
Turn source assets into short demo shots
Keep the full owner/input/output workflow on the deeper page; this summary only shows the operating shape.
-
1
Prepare source assets
Gather product screenshots, one short screen recording, or the release notes that define the feature change.
-
2
Generate short shots
Prompt one 5-8 second shot at a time so the tool is solving a visible product moment, not the whole story.
-
3
Review and assemble
Keep the shots that explain the feature clearly, repair only the broken beat, then assemble a 15-60 second demo.
Compact tool recommendation
Use one primary tool and one fallback
Detailed model coverage belongs on the comparison page. This summary keeps the first decision tight.
Runway
Start
Controlled SaaS product shots, UI transitions, and first-pass demo structure.
Do not ask it to solve a whole launch video in one prompt.
Best first pass for a controlled short SaaS demo.
Pika
Fallback
Punchier motion tests when a static screenshot needs more energy.
Avoid long UI-heavy walkthroughs that need stable text and exact continuity.
Best fallback when motion energy matters more than interface precision.
Internal worked example
A product update turned into a demo draft
This is labelled as an internal worked example, not a customer proof claim.
Two product screenshots, one 18-second screen recording, and a short release note.
Tool: Runway (internal test plan). 3 attempts. 45-60 minutes, low-credit pilot range. First failure: The first output drifted away from the UI and made the CTA feel generic.
Change made: The prompt was narrowed to one screen state per shot and the CTA was moved into the final beat.
A 30-second SaaS feature update demo for a product marketer to publish.
A clean 30-second demo draft with an intro shot, a feature proof shot, and a CTA shot.
