Also checked on this input — same tool, 4 other criteria

Avatar realism✓ WorkedGenerates a convincing photorealistic talking-head avatar, with the report noting natural skin, hair, teeth, expressive gesturing, and no visible deformities or robotic feel.B-roll / product integration✗ FailedThe tool can keep the ad as one unbroken static talking-head shot, with no product screenshot, cutaway, or other supporting footage to integrate the SaaS visually.Caption quality✗ FailedThe tool can export a clip with zero on-screen captions for the full 18.4 seconds, so captioning is not baked into the output.Product understanding✗ FailedFor a SaaS-discovery prompt, the tool can misread the product context by choosing a generic classroom/math-teacher template instead of a relevant tech-review persona, signaling weak product mapping.

HeyGen✗ FailedThe output only fills about 55% of the 9:16 canvas, leaving large dead white bars top and bottom, so the clip is not a native full-bleed vertical export.Synthesia✗ FailedThe FutureSmart output was generated in landscape rather than the requested vertical 9:16 short-form format.
