Avatar realism✓ WorkedGenerates a believable photorealistic presenter with convincing face detail and natural-looking motion; the report describes excellent skin texture, eyes, teeth, and close-up realism.B-roll / product integration✗ FailedThe tool can omit all product-supporting footage, producing a tight face-only crop with no held-up product, no B-roll, and no scene variety.Caption quality✗ FailedThe tool can export a clip with zero on-screen captions for the full 15.8 seconds, leaving the short-form ad uncaptioned.Product understanding✗ FailedFor a physical-product prompt, the tool can omit the product entirely and keep the ad grounded only in a face-only testimonial shot, so the product itself is never actually integrated.
