Round 03

Marketing videos vs corporate training

HeyGen and Synthesia have settled into two different markets. HeyGen is where marketers, LinkedIn creators, and sales teams produce avatar videos. Synthesia is where L&D departments and HR teams produce employee training content.

The split shows in the features each one leads with. HeyGen optimises for fast video creation, social formats, and video translation. Synthesia optimises for training: interactive videos, surveys, roleplay practice, and on its Enterprise plan SCORM export, brand kits, and live team collaboration.

If you are not sure which category you fall into, the answer is probably HeyGen. Most people asking this question are marketers or solo creators, not L&D managers.

The line is less sharp than it used to be, though. HeyGen's Business plan now lists SCORM export and LMS integrations, and Synthesia lists SCORM only on Enterprise. A small training team that needs SCORM on a published price should look at HeyGen Business before assuming Synthesia is the only option.

Stock avatar counts now depend on the plan. HeyGen lists 700+ stock avatars on Creator. Synthesia lists 125+ on Starter, 180+ on Pro, and its full 240+ library on Enterprise. Both libraries are large enough that you will find something usable without a custom avatar.

Custom avatars are available on both. HeyGen includes custom avatars from the Creator plan ($24 a month billed yearly). Synthesia includes 3 personal avatars on Starter, 5 on Pro, and unlimited on Enterprise, with a consent recording as part of setup. Output quality from both is comparable — a realistic speaking avatar that holds up in a business context.

Avatar quality is close enough that it should not be the deciding factor. Both produce professional-looking output that is recognisably AI but good enough for training videos, marketing content, and internal comms. If demographic variety in stock avatars matters and you are on an enterprise budget, Synthesia's full library is a genuine advantage; below Enterprise, HeyGen's stock library is larger.

HeyGen and Synthesia both provide a free tier for testing avatar quality before you pay: HeyGen gives 3 watermarked videos a month up to 1 minute, and Synthesia 500 credits a month (up to 10 minutes of video) with a watermark.

Round 05

Video translation and lip sync

HeyGen's video translation is one of its clearest strengths. Upload a video, select a target language, and HeyGen re-renders it speaking that language with matching lip sync. Paid plans list 175+ languages and dialects (the free plan 30+), and the output is convincing enough to use in marketing content without re-recording.

This matters for companies selling internationally. A product demo recorded in English can be translated into Spanish, Portuguese, German, and Japanese without a new shoot. The lip sync is not perfect in every language, but it is a big step up from subtitles alone.

Synthesia has caught up here too. Every plan includes AI dubbing with a monthly allowance — 10 minutes on the free plan, up to 16 extra minutes on Starter, and up to 78 on Pro — in 70+ languages below Enterprise. Enterprise adds one-click translation of whole Synthesia videos into 140+ languages.

If you produce marketing video for many language markets on a mid-range budget, HeyGen's translation is the stronger fit. For training libraries translated at enterprise scale, Synthesia Enterprise's one-click translation is built for that job.

SCORM export is the feature corporate training teams ask about first. SCORM is the standard format for e-learning content that plays inside an LMS such as Workday Learning, Cornerstone, or SAP SuccessFactors, and it lets the LMS track whether a learner watched and completed a module.

Both tools now offer it, on different plans. HeyGen lists "SCORM export and LMS integrations" and a brand kit on its Business plan ($149 a month plus $20 per added seat). Synthesia lists SCORM export (including translated versions), brand kits, live team collaboration, and SAML/SSO on its Enterprise plan, which has custom pricing.

What Synthesia adds is a training-first product around those features: interactive videos and branded video pages on Pro, plus surveys and AI roleplay practice for learners. For an L&D department running a large training library, that focus is the reason to choose it.

Do not pay for training features you will not use. A solo marketer paying for Synthesia Pro ($59 a month billed yearly, $89 monthly) instead of HeyGen Creator ($24 billed yearly) is paying for features they will never touch.

The decision is straightforward once you know your use case.

Choose HeyGen if you are a marketer, solo creator, or sales team producing avatar videos for LinkedIn, YouTube, product demos, or customer communication. Creator at $24 a month billed yearly ($29 monthly) covers it: 700+ avatars, custom avatars, videos up to 30 minutes, and lip-sync translation. If you also need SCORM for a smaller training programme, HeyGen Business includes it at a published price.

Choose Synthesia if you work in L&D, HR, or corporate training and want a platform built for it. Starter at $14 a month billed yearly is the cheapest entry of the two, and Pro adds interactive videos and branded pages. Budget for Enterprise if you need SCORM export, brand kits, or one-click translation, since Synthesia lists those only there.

If you are not sure which category applies, test both free plans before paying. ElevenLabs is worth considering alongside either tool if high-quality voice cloning for narration is a priority. And if neither fits, the Synthesia alternatives roundup covers the wider field, including Colossyan and D-ID.
