What the price counts

Everything is metered in credits from one shared balance, on top of a 10-minute monthly video allowance: Basic 500, Starter 1,750 and Pro 6,500 credits a month.

Credits are one shared balance for every feature that uses credits, including video creation, dubbing, surveys, Interactive Avatars, B-roll, and the…

Voices that use more

The allowance drains faster for heavier output: lip-synced dubbing doubles the per-minute rate, avatars on screen throughout cost more than 100 credits a minute, and the Syren agent burns 1,000-2,000 credits per finished minute.

Match mouth movements to the translated audio. Uses 2x credits when enabled.

Cloning a voiceYes

Instant cloning

A voice clone is recorded in the Voices tab from about twenty seconds of speech and is ready within minutes, and the plan comparison lists Voice Cloning as a platform feature.

Professional cloning

Synthesia itself sells only the instant clone; a higher-fidelity Professional Voice Clone has to be created in ElevenLabs and transferred in, and the comparable premium avatar tier is a $1,000-a-year annual-plan add-on.

Dubbing and translationYes

Video dubbing

You upload a file or paste a YouTube link, pick target languages, and the dub keeps each original speaker's voice, accent and tone; dubbing is available on every plan including Basic.

Preserve the original speaker's voice, accent, and tone in the dubbed version.

Dubbing and translationYes

Lip sync

Lip-sync is offered on every plan as an option in the dubbing setup, and switching it on doubles the credits a minute of source video consumes.

If your video features people speaking, we'll sync their lip movements to the translated audio.
