2What it means for delivery
A single shape decides the platform before the first shot. A 16:9-only model suits a widescreen release and nothing vertical without cropping; a 9:16-only drama tool suits mobile feeds and nothing on a television. Tools that offer both have their own question here.
No figure on aspect ratios from 10 vendors: Crreo, DomoAI, Flixly, HeyGen, Higgsfield, Kling AI, M Studio, MagicLight, Pika and Runway.
