HeyGen

Strengths

  • A custom avatar is included even on the free tier, which Synthesia reserves for paid plans
  • Voice cloning and translation are stronger than the category norm
  • 4K export from the $49 Pro tier
  • Unlimited photo avatars on Creator

Trade-offs

  • Business pricing is $149/month plus $20 per seat, so team cost climbs faster than the headline suggests
  • Credit-based pricing is harder to plan against than Synthesia's minutes
  • Free tier caps videos at one minute each

  • Translating and dubbing existing video into other languages
  • Anyone wanting a custom avatar without paying first

  • Large teams on the Business tier, where per-seat pricing stacks on top of the base
  • Long-form video on the free tier, which is limited to one minute

Synthesia

Strengths

  • A genuinely usable free tier at 10 minutes a month with no card required
  • 160+ languages and voices on every plan, including free
  • SCORM export and LMS fit make it the default for corporate training
  • Annual billing is close to a third cheaper -- $18 against $29

Trade-offs

  • Minutes, not credits, are the real constraint and 12 a month on Starter goes quickly
  • Avatar-led video suits explainer and training content and little else
  • Personal avatars require the Creator tier
  • Monthly billing carries a steep premium over annual

Synthesia: who it suits

Buy it if

  • Corporate training and onboarding video at scale
  • Localising one script into many languages without re-shooting
  • Teams with no video production capability

Skip it if

  • Marketing video where a real presenter carries the brand -- avatars still read as avatars
  • Anyone needing more than about 30 minutes a month without moving to Enterprise
  • Creative or narrative video, which is not what this generates
