HeyGen

Start with one 45–60 second Free project using material you control, but treat its output only as personal, non-commercial internal evaluation: do not publish, monetize or deliver it. Move from audio preview to the rendered avatar, correct the failed scene, and test captions, brand checks and the delivery format in your normal editor. Generate the deliverable only after moving to Creator, Pro or Business, recording the current terms and clearing every input right. Pay for Creator when watermark-free 1080p or monthly volume removes a measured block; choose Pro for a real 4K, translation-script or credit need, and Business only for team workflow or add-on capacity.

Best fitRepeatable scripted presenters
HeyGen fits training, explainers, product updates and localized presenter videos whose script, brand frame and approval path repeat across episodes or markets.
Pause firstThe message or identity is not approved
Pause when the script still changes, the speaker has not consented, confidential client material cannot enter the service, or live performance and original filming are the real value.
Decision testFinish one representative minute
Use the intended avatar, voice, language, on-screen text and export path; count credits, render attempts, correction time and only the seconds accepted into delivery.

Synthesia

Use Basic to build and generate one representative minute, but include download and handoff in the test because downloading is a Starter feature. Preview every scene before generation, then review the generated avatar version and correct only the affected scene. Choose Starter for downloadable, logo-free regular production; Creator for measured 30-minute capacity, API, interactive or multi-avatar needs; Enterprise only when live team editing, SSO, SCORM, brand governance or organization-scale localization is required.

Best fitRepeatable business and learning videos
Synthesia fits structured training, onboarding, policy updates and explainers whose script, scene template, brand rules and review path repeat across versions.
Pause firstThe lesson and approvals are not stable
Pause when subject experts still dispute the content, learners need a live demonstration, paid advertising is planned with stock avatars, or no one owns final review.
Decision testApprove one real minute end to end
Build the intended scene, preview voice and assets, generate it, collect comments, correct the version, download or share it as planned and count all regenerated seconds.
