HeyGen or Synthesia for multilingual avatar videos a team reviews and publishes

Languages and dubbing: two vendors count different things

Take one script that must come out in five languages. HeyGen lists 30+ languages on the Free plan and 175 languages and dialects from Creator upward. Its homepage describes translation with voice cloning and lip-sync across 175+ languages and dialects, a brand glossary, and translation of an uploaded file or a YouTube link. The Free plan only gives a limited trial of lip-sync translation.

Synthesia separates two numbers. Video creation covers 140+ languages and voices on every plan. Dubbing of existing video covers 70+ languages on Basic, Starter and Pro, and 140+ on Enterprise, with voice and accent preservation and lip-sync listed. Dubbing costs credits: 80 per minute with lip-sync, 40 without.

So 175 and 140 are not the same measure. What matters is whether your five languages are supported, with lip-sync, on the plan you would actually buy. That is a question for a trial, not for a headline count.

The executive avatar: consent first, then plan ceilings

Both vendors require the executive to appear on camera once. HeyGen says every custom avatar needs on-camera identity verification from the person depicted. Synthesia builds a Personal Avatar from a photo or short video and requires a live, on-camera consent recording.

The ceilings differ. HeyGen's pricing table shows one custom video avatar on Free and 1+ on Creator and Pro, with additional avatars as an add-on. Synthesia's table shows 5 personal avatars on Pro and unlimited on Enterprise, subject to reasonable consumption. A studio-shot avatar is a paid add-on at $1,000 a year on Synthesia's paid plans. If several executives need avatars, count them against the plan before comparing prices.

Review by a team: seats, guests and approval

HeyGen's individual plans have one user seat. Its pricing FAQ places team work at the Business plan, $149 a month plus $20 per seat a month. The homepage describes comments, tagging and multi-user editing in AI Studio, and the security page mentions SSO and SCIM for enterprise customers.

Synthesia's plans are built around one editor plus guests: Starter has 1 editor and 3 guests, Pro 1 editor and 5 guests. Live collaboration and SAML/SSO are listed on Enterprise, and the homepage mentions roles, permissions and an approval step before videos go live. Confirm what a guest can do in review before you rely on guests as your reviewers.

Publishing: developer APIs or a learning stack

Synthesia's documentation lists integrations with 360Learning, Articulate 360, Docebo and Moodle, with BambooHR and Workday for syncing employees, and with Teams, Slack, HubSpot, Intercom, YouTube and Vimeo. It also publishes by link, embed or SCORM, and its dubbing API accepts a lip-sync flag.

HeyGen's homepage announces HeyGen for Developers, with APIs for Video Agent, video generation, translation and lipsync. That suits a team that wants to trigger translation from its own code. For a SCORM package into an LMS, Synthesia is the documented route; HeyGen's pricing table has a SCORM export row, so confirm which plan includes it.

What customers actually did

On HeyGen's side, I Love Happy Cats is a solo founder who began by uploading existing English videos to get French and German versions, then localized a 56-video course into languages including Italian, Russian, Hungarian and Japanese. Native speakers she asked reviewed test videos; HeyGen's case study reports start-to-finish production 5x faster. The AI Department works differently: real estate agents pick a topic, a script is drafted in their tone, HeyGen produces a first version, and the company's editors review every video, add B-roll and publish.

Synthesia's published stories are enterprise training. Merck KGaA describes reaching more than 60,000 people across dozens of countries in their own language; Carlsberg reports 100+ creators in under two years; LBBW produces more internal videos in-house under central governance. Ryanair reports passenger videos going from over an hour to minutes. These are vendor-published results from different populations and metrics, not a benchmark between the tools.

Data handling and cost per video

HeyGen states SOC 2 Type II, storage in the United States on AWS, the EU-US Data Privacy Framework and standard contractual clauses for transfers. Enterprise data is excluded from model training by default; other customers must email to opt out. Synthesia lists SOC 2 Type II, ISO 27001, ISO 27701 and ISO 42001, makes a data processing agreement available, and its homepage cites EU data residency.

Both bill in credits. Synthesia states about 100 credits per finished minute of video; HeyGen says credit use varies by model, duration and complexity, and gives no per-minute figure. Editorial suggestion, not a vendor feature: run the same script in your five languages on each trial, have native speakers judge lip-sync, record credits consumed, and push the result into your real publishing tool.
