The preview was available immediately in-platform, so the animation could be inspected before any external capture step.
What was measured
In-Platform Preview
Real-time preview before export.
context, not decisivecapability
Previewing before export helps iterate, but it does not itself measure whether the tool can generate the animation correctly. (3 of 3 judges)
What was given, what came back
Test input: Search engines basics explainer · text
Input — what we sent
The exact prompt
Create an animation video explaining how search engines work.
A vague, linear educational animation prompt asking the tool to explain how search engines work with minimal guidance. Designed to stress inference, scene structuring, pacing, and coherent visual flow from an underspecified request.
Output — unretouched

Code Generation Quality✓ WorkedIt generated a runnable webpage on the first attempt, with autoplay working on load.Export Experience⚠ StruggledGetting an MP4 was not native; the report says a browser-capture/render workflow was still required.Output Quality✓ WorkedDelivered a polished animation with smooth motion, clean hierarchy, and a recognizable search-engine workflow.Reliability◐ MixedThe animation works, but timing and pacing still often need manual refinement.
