HeyGen Creator ($29 / 600 credits) theoretical max is ~37.5 min Avatar IV Photo Look or ~19.4 min Video Look — not a finished-video guarantee; Synthesia Starter gives 10 shared-credit video minutes — but Synthesia wins on languages, templates and enterprise fit. Who should pick which.

How we work
Every price and plan limit on this site is checked against the vendor's own pricing page and stamped with the date we checked it. We add hands-on notes as we run the same test scripts through each tool. Some links are affiliate links; that is disclosed on every page that has them, and it has no effect on which tool we recommend — we link to tools we don't earn from (HeyGen, for one) when they're the right answer.

Six questions â” ’ the plan you should start on. Plus 12 copy-and-adapt scripts for onboarding, product, policy and explainer videos, and a one-page pilot scorecard.
