Short-form is a volume game: the winning workflow tests five hooks and posts the best one. That makes cost per attempt the deciding metric, not peak quality — phone screens forgive resolution, but the algorithm doesn't forgive slow posting. Sora 2 earns the top spot by combining portrait-native output, synced audio (crucial: sound drives short-form retention) and a $0.80–1.20 per-clip price.

For pure volume, Vidu and Kling's subscription cut per-clip cost to ~$0.30–0.40, letting you A/B-test hooks the way big accounts do. Budget rule of thumb: a daily-posting account generating three candidate clips per post spends $30–90/month on Sora 2, or under $40 on the volume tiers.

Whichever pick fits, pressure-test the budget in the calculator with your real clip counts — and remember every rate above multiplies by your retake ratio.
