HeyGen vs Synthesia: Credits, Avatars and Training Workflows

Compare HeyGen and Synthesia around the deliverable: a scripted avatar clip, a translated presentation, an interactive lesson or a learning-platform package. Both now use credits for AI work. An old comparison of unlimited HeyGen output against capped Synthesia minutes misses the current plans.

When HeyGen fits

HeyGen Creator includes a Custom Digital Twin, voice cloning, 1080p export and watermark removal. Pro adds 4K export and the ability to edit translated scripts. If you are making variants of a presenter-led message, those are useful things to include in your sample project. HeyGen current plan guide.

New Creator subscriptions have 600 monthly credits and a per-video duration limit. Eligible active legacy unlimited subscriptions can remain on their legacy terms. Those numbers describe different limits. Creator does not support one-time credit purchases, so consider how an extra revision batch would affect your plan.

When Synthesia fits

Synthesia Starter provides downloads, logo removal and AI Dubbing. Creator adds interactive video, API access and multiple avatars per scene. Enterprise lists SCORM export, SAML/SSO and live collaboration. Synthesia pricing.

For training, define delivery first. A downloadable video, an interactive hosted lesson and a SCORM package are distinct requirements. Confirm the format your learning platform accepts and test tracking before choosing a plan for an entire course catalogue.

Compare the real commitment

The entry monthly subscriptions both cost $29, but the two credit balances are not the same currency. Neither a larger credit number nor a longer maximum video proves a lower cost per accepted deliverable. Include translation, generated assets and revision work in your estimate.

Synthesia Starter’s annual equivalent is $18 per month, a computed $216 annual total; Creator is $64 equivalent, a computed $768 annual total. Its annual page lists annual credit pools rather than identical monthly allocations. HeyGen annual pricing was not verified in the retrieved page and is omitted.

Put the same onboarding lesson through both workflows

Imagine a two-minute onboarding lesson that teaches staff to submit an expense receipt. The deliverables are an English version, a Spanish version and a manager-approved export. The lesson has three scenes: a presenter introduces the task, a screenshot shows the required fields, and the presenter explains what happens after submission. This is an illustrative production brief.

In HeyGen, build the presenter scenes around the approved script and keep the screenshot visible while its fields are named. The useful control is alignment: the viewer should see “receipt date” when those words are spoken. Creator's 1080p export may satisfy an ordinary internal video; choose Pro because you actually need its translated-script editing or 4K capability, rather than because the lesson is for a business.

In Synthesia, build the same three scenes and review the same two language versions. If the manager wants a question after the explanation, Creator's interactive-video capability becomes relevant. If the learning system requires a SCORM package, move that requirement to the start of procurement: the current page places SCORM on Enterprise. A normal downloadable file and a learning package that reports activity are different deliverables.

Give a fluent Spanish reviewer the source script, translated script and rendered lesson. A sentence may be translated accurately yet run longer than the screenshot display. Fix narration and scene timing together. A manager approving by a review link does not automatically need the same access as the person changing the scene; establish who edits before counting seats.

The revision that reveals the real cost

Now change the receipt deadline in the final scene. The project needs consistent updates to both languages, the visible text and the released copies. Count that revision as part of the trial. Your useful output is two approved lessons, not the first two renders.

Start with HeyGen for a straightforward presenter lesson when the chosen plan covers its export and translation controls. Start with Synthesia when the lesson's interaction or learning-system delivery is the deciding requirement. If all you need is a demonstration of three form fields, a narrated screen recording may remove the avatar stage altogether. Choose after the manager accepts the complete lesson and the destination system accepts its delivery format.

Frequently asked questions

Is HeyGen Creator unlimited video?

No. Its current plan is credit-based, with 600 credits monthly. The per-video duration limit is a separate constraint.

Is Synthesia always more expensive?

Both entry paid monthly plans listed here cost $29. Actual project cost depends on feature usage and revisions, not just the entry price.

Which lists SCORM export?

Synthesia’s current pricing page lists SCORM export under Enterprise. Verify the package and tracking requirements with your learning platform.

Are Synthesia guest seats editor seats?

No. The current Creator card separately lists one editor and five guests. Do not budget as though that means six editors.
