Is Synthesia worth it? Decide with one approved training video

01Use Synthesia when script, template and review can be governed

Its strongest fit is a repeatable information product, not a one-off promise that an avatar replaces every kind of filming.

The editor combines a scene list, canvas and script box. Each scene can carry an avatar, voice, language, text and media, while comments and generated versions create a traceable review path. This suits training and operational communication where a controlled template matters as much as the presenter.

Before the trial, open the web app in the latest Chrome; the current supported minimums are Chrome 133 and Edge 134. Desktop requirements start at Windows 10 or Server 2016, macOS Catalina 10.15, or the listed 64-bit Linux releases. Self-serve users can use selected features such as AI Playground in a mobile browser, but the full video editor requires a desktop or laptop; Enterprise mobile use is not supported. Do not treat a successful mobile prompt as proof that the editing workflow fits.

Keep the boundary explicit: approved learning objective, script and source assets enter; a reviewed video version leaves. Subject expertise, factual sign-off, accessibility, final platform packaging, complex footage work and durable source storage remain outside the avatar generator.

• Define the audience action or learning outcome before choosing an avatar.
• Keep one source of truth for the script and assign subject, language, brand and publication approval.
• Archive the script, scene map, selected avatar and voice, comments, generated version and delivered file together.

02Choose Basic, Starter, Creator or Enterprise from the first blocking requirement

Verified US prices and credits are planning data; local checkout and the active contract control other markets.

Basic is free with 1,200 credits per month and up to 10 video minutes, but downloading is listed as a Starter addition. Starter is USD 29 monthly or USD 18 monthly equivalent when billed annually, with 1,200 monthly or 14,500 annual credits, up to 10 minutes monthly or 120 annually, one editor and three guests. Creator is USD 89 monthly or USD 64 equivalent annually, with 3,600 monthly or 44,000 annual credits, up to 30 minutes monthly or 360 annually, one editor and five guests plus API, interactive and multi-avatar features. Enterprise is custom.

A self-serve generated second uses two credits. Unused credits reset rather than roll over, and self-serve users cannot top up mid-cycle. Creator is not a multi-editor plan merely because it adds guests; live team editing, SSO, SCORM, broader brand controls and organization-scale features belong to Enterprise.

• Use Basic to prove scene construction and generation, then test the required export path before choosing a paid plan.
• Choose Starter when download, logo removal, regular 10-minute capacity and guest feedback remove the real block.
• Choose Creator or Enterprise only for a named capacity, API, interactivity, avatar, collaboration, governance or LMS requirement.

03Finish one approved minute before scaling templates and languages

A draft preview reduces avoidable errors, but avatar lips and the final generated performance still require post-generation review.

Break the final script into short scenes by idea. Preview the voice, pronunciation, visual assets, music and transitions. The scene preview does not animate avatar lips, and AI voices are nondeterministic, so record the selected language and voice and expect the generated version to need a final performance check.

Invite reviewers while the structure is still cheap to change. Resolve factual, brand and language comments before generation, render the representative minute, inspect every avatar and caption, then change only the affected scene. Test the actual download, shared page or learning-platform handoff before duplicating the project.

For delivery, generate the video before choosing the file. The current guide lists MP4 at Full HD 1080p (1920×1080), WAV audio, XLIFF for translation, and SRT or VTT captions. An interactive video with buttons or branching cannot be downloaded as MP4: preserve interactivity through a website or LMS embed, SCORM or a share link. If the buyer requires a file, duplicate the video, remove interactive elements, regenerate it and deliver the non-interactive MP4.

• Put the most difficult name, number, pronunciation, visual proof and transition into the trial.
• Separate content comments from performance comments so the next action is clear.
• Do not translate a template at scale until one source-language master has passed delivery and accessibility review.

04Measure delivered-minute cost after regeneration

Ten or thirty plan minutes describe first-pass capacity; the approved minutes left after changes describe production value.

Record the subscription share, every generated second, every regenerated version, discarded scenes, reviewer time and final delivered duration. Effective Synthesia cost per finished minute equals the project share of Synthesia spend divided by delivered minutes. Keep script writing, subject review, translation, accessibility and downstream editing as separate labour costs.

Self-serve video generation consumes two credits per second, so one generated minute uses 120 credits. When an edited video is regenerated, the credit charge is recalculated from the updated full duration, not only the sentence that changed. Short scenes and pre-generation comments reduce waste, but unused plan credits do not accumulate into the next period.

• Log the balance and duration before each generation instead of reconstructing usage later.
• Track generated programme duration, changed-scene duration and accepted delivered duration separately.
• Set a revision cutoff and fallback to voice-over slides, recorded screen demonstration or live presenter when regeneration stops paying back.

05Separate stock-avatar licence, custom-avatar consent and customer data

Owning the final training message does not make every avatar, media asset, promotion channel or person's likeness interchangeable.

Synthesia permits stock and synthetic avatars for uses such as training, product pages and organic social publishing, but the published licence excludes paid social advertising, paid programmatic promotion and TV without permission. Custom-avatar videos follow the agreement with the represented person and require free, informed consent and applicable legal age. Decide the distribution channel before selecting the avatar type.

The customer owns Customer Data and grants Synthesia a limited licence reasonably necessary to operate, maintain and improve the service, address support or security, meet law or follow written permission. Synthesia states that customer inputs and outputs are not used to pre-train its AI components and that fine-tuning with Customer Data requires written customer instruction. The customer still remains responsible for lawful inputs and publication.

• Record avatar type, consent owner, intended channels and licence check with each published version.
• Do not repurpose a stock-avatar organic video as a paid advertisement without the required permission.
• Review integrations, retention, access and the governing customer contract before confidential or regulated work.

06Compare Synthesia, HeyGen and recorded training by workflow

Use one approved script and delivery target; avoid a borrowed ranking of which avatar is universally more realistic.

Compare Synthesia and HeyGen with the same script, language, avatar type, preview and correction loop, reviewer roles, distribution licence, delivered-minute cost and output destination. The useful difference is which workflow constraint each service removes, not an unsupported realism score.

Use recorded screen demonstrations or a human trainer when the learner must see a changing interface, physical procedure, authentic performance or live judgment. Use slides with voice-over when a presenter adds little value. Synthesia earns a place when scenes, governance, comments and repeatable localization reduce update cost without weakening accuracy or permissions.

• Review both candidates inside the same lesson sequence, captions, quiz or LMS page.
• Count reviewer coordination, regeneration, licensing checks and maintenance time with subscription price.
• Keep scripts, visuals and source files portable so the programme can switch between avatar, narration and recorded presenter.
