Synthesia AI dubbing costs: minutes per plan and lip sync

Synthesia AI dubbing costs no separate fee: it is paid from your plan's monthly credits. On monthly billing, Starter ($29 a month) covers up to 48 minutes of dubbing, Creator ($89 a month) up to 140 minutes, and Enterprise lists unlimited dubbing at a custom price. Turning on Lip Sync uses twice the credits.

Every Synthesia figure here comes from its own pricing page, read on 2026-09-29; Synthesia can change it at any time. The Sume rates at the end are read from the code behind API pricing and the Sume API reference.

How many dubbing minutes does each Synthesia plan include?

Each plan card says what its credits are "usable for up to": a number of minutes of video, or of AI dubbing, or of generated video assets. The last column divides the monthly price by the dubbing minutes, so it only holds if every credit goes to dubbing.

Do dubbing minutes share credits with video minutes?

Yes. Synthesia calls credits "the shared currency across all AI usage-based features - one common pool for everything you create." On Starter, the same 1,200 monthly credits cover up to 10 minutes of avatar video or up to 48 minutes of dubbing, not both. Minutes you spend on avatar videos come out of the dubbing budget.

Synthesia's FAQ also says usage is capped until renewal once you exceed your limit, unused video minutes do not roll over, and you cannot pay per video: it sells monthly and yearly subscriptions only.

What does lip sync add to the cost?

The pricing page describes Lip Sync as "Match mouth movements to the translated audio. Uses 2× credits when enabled." A lip-synced minute therefore costs twice the credits of a plain dubbed minute, so a plan's credits cover half as many lip-synced minutes.

The same dubbing section lists file upload or a YouTube link as input, voice and accent preservation, a custom glossary, transcript editing and a Dubbing API. The page text does not show which of these each plan includes, so check the plan grid before you buy for them.

What does dubbing cost on yearly billing?

On yearly billing the page lists Starter at $18 a month and Creator at $64 a month, with 580 and 1,760 minutes of dubbing a year. Its FAQ quotes different annual totals ($264 for Starter, $804 for Creator), so confirm the yearly price at checkout.

Output languages for dubbing are listed as 70+ on Basic, Starter and Creator and 140+ on Enterprise.

What does dubbing cost when you build it from API steps?

Sume has no single dubbing product. You transcribe, translate the text yourself, speak it with TTS 1.0 (set language for every non-English transcript) at $0.0475 per 1,000 characters, and, for a talking face, lip-sync that audio onto a still or avatar with VEED Fabric 1.0 at $0.1875 per audio second (720p), about $11.25 per minute of audio, plus a 5.5% agent fee by default. Fabric takes a still image, not a filmed video, and one request takes up to 300 seconds of Sume-hosted audio under 10 MB (Models, Sume API reference).

AI dubbing rate per minute works through the full per-step math, and How to dub an avatar video shows the requests. Sume Avatar 1.0 talking videos speak English only in current code, so translated speech goes through TTS, not the avatar script.
