AI Video Generation Index: Pro Editors, Avatar Stables and the Sora Reckoning
Seven tracked video tools, three distinct form factors, and a pricing spread from $9/mo seats to enterprise studios.
The video category has quietly split into three businesses that happen to share a label: generative video models (Runway, Pika, Sora), avatar-led corporate video (HeyGen, Synthesia), and AI-augmented editors (Descript) or image-first models expanding into motion (Midjourney).
Scoring them on one axis is misleading, so this index keeps the five-dimension Airecmark composition as the common denominator and calls out form-factor fit separately. Avatar platforms win on usability and enterprise workflow fit; generative models win on raw capability ceilings; editors win on adoption economics.
One structural fact dominates the category this cycle: OpenAI's standalone Sora product was discontinued in April 2026, with the model continuing via sora.com — a reminder that model quality and product durability are separate scores. Our value dimension reflects that honestly.
