measured on B-roll / product integration

AKOOL✗ FailedAdds no app UI or other product footage at all.HeyGen✗ FailedThe supporting footage is not product-integrated because the cutaway uses the wrong app entirely, so the B-roll does not match the Duolingo testimonial being spoken.Invideo AI◐ MixedThe clip adds a timed phone-and-coffee cutaway, but the screen content is blurred and generic instead of product-specific, so the supporting footage does not fully reinforce the app.JoggAI✗ FailedThe tool can produce a single static shot with no cutaways and no product visuals, so the app never gets any supporting footage.VEED⚠ StruggledThe Duolingo output is a talking-head clip, and the report says the Duolingo UI was not automatically included, so contextual app visuals were not supplied by default.Vidnoz AI✗ FailedDoes not add app UI or other contextual footage; the output remains a generic talking-head video with a plain background.
