Model comparisons fail when they compare “taste”.
In ecommerce creative, you should compare production truth.
Pick one product direction, then test models under the same QA gates. The winner is the model that preserves the bottleneck you care about.
Key Takeaways
– Stop ranking by hype; compare by bottleneck.
– Use one direction kit and one QA checklist across models.
– Choose the model that passes your gates on your real export formats.
The bottleneck checklist
For image-to-video, bottlenecks usually look like:
- geometry drift (edges and proportions change),
- texture instability (materials look “off” during motion),
- label readability (text/labels become unreadable after resizing),
- shadow family mismatch (tone shifts and breaks brand world).
Experiment design
- Lock the direction kit:
- Run each model with the same kit.
- Apply the same QA gates:
- Export the same channel variants and compare end results.
– world promise, – identity anchors, – and scene roles.
– geometry gate, – readability gate, – world continuity gate, – offer alignment gate.
If a model passes gates on one format but fails on another, it is not your winner.
