After running several AI video tools through real marketing workflows (short-form ads, explainers, social clips), our takeaway is clear: the best tool isn’t the one with the flashiest model — it’s the one that produces usable campaign assets with the least editing friction. Measure cost per usable creative, not just the monthly price.
