Moving projects between avatar video platforms is less about “export/import” and more about protecting the pieces you’ve already paid for: scripts, source media, brand rules, and the way your team ships videos. This checklist focuses on HeyGen to Synthesia migration with a safe, reversible approach for small-business owners and team leads—so you can test Synthesia Starter without breaking your HeyGen Creator pipeline. Expect a two-week pause window, parallel publishing, and a clear renewal decision at the end.
Before you touch anything: decide what “success” means
A migration is only worth doing if it improves a workflow you actually use. Pick 2–3 measurable outcomes you can verify internally (not vendor claims), such as:
- Faster review/approval loops for training or enablement videos
- More consistent branding across teams and templates
- Easier multilingual output management (for your specific languages and review process)
- Lower rework caused by pronunciation, captions, or asset drift
If your primary output is creator/marketing content with frequent iteration, HeyGen’s creator-oriented framing may already match your cadence. If you’re building structured training/enablement videos with repeatable layouts and business workflows, Synthesia’s framing may fit better. Keep the decision conditional on your real use case.
Pricing baseline (verify before committing)
As of 2026-07-12, HeyGen Creator is $29/month and Synthesia Starter is $29/month. Effective cost can change with credits, premium generation, translation, resolution, and higher tiers—so confirm current details on vendor pages before you decide: HeyGen — pricing and Synthesia — pricing.
Migration map: what can move vs. what must be rebuilt
Most teams can reuse content but must recreate platform-specific items. Plan for:
Typically reusable (with prep):
- Scripts and storyboards
- Raw source media (logos, b-roll, screenshots, slides)
- Brand guidelines (fonts, colors, lower-third rules)
- Pronunciation notes (as a document)
Typically rebuilt (platform-specific):
- Avatars/digital twins (even if both support personal avatars)
- Voice selections and exact voice settings
- Scene templates and layouts
- Captions/subtitle styling and timing preferences
- Hosted pages and embed workflows
- Integrations and publishing automations
Two-week safe migration plan (with a deliberate pause)
Week 0 (prep): freeze scope and inventory everything
Create a single “Migration Inventory” spreadsheet with these columns:
- Video name + link (HeyGen project + published URL)
- Owner + last updated date
- Script source (Doc/Notion/Slides) + version
- Source media folder link
- Avatar used (type + notes)
- Voice used + settings notes
- Pronunciation guide link
- Captions/subtitles status + languages
- Template/brand kit used
- Hosted page/embed location(s)
- Integrations touched (Zapier, LMS, CMS, etc.)
- Priority (P0 must keep live, P1 soon, P2 archive)
Then declare a two-week pause on structural changes (new templates, new brand kits, new integration work). You can still publish urgent videos, but only with “migration-safe” rules: scripts stored outside the platform and assets saved in a shared folder.
Week 1: build a reversible pilot in Synthesia Starter
Pick 3 representative videos (not your easiest ones):
- A short marketing/announcement style video
- A structured training/enablement segment
- A multilingual or caption-heavy video
Rebuild them in Synthesia with the same scripts and source media. Keep HeyGen versions live. Your goal is not perfection—it’s to learn what breaks: timing, pronunciation, template fidelity, review flow, and publishing.
Week 2: parallel run + decision checkpoint
For two weeks, run both tools:
- New requests: decide case-by-case which platform to use
- Edits: keep edits in the original platform unless the video is in the pilot set
- Publishing: use the same distribution channels; track feedback and rework time
At the end of week 2, hold a 30-minute checkpoint with stakeholders: what improved, what got worse, and what would need redesign.
Asset-by-asset migration checklist (safe and boring on purpose)
Scripts (protect the source of truth)
- Store scripts outside HeyGen (Docs/Notion/Slides) with version history.
- Add a “scene map” section: Scene 1–N, on-screen text, and media references.
- Standardize naming:
Project_VideoName_Lang_V#. - For each pilot video, paste the script into Synthesia and confirm formatting rules for on-screen text.
Source media (make it portable)
- Export/download originals: logos, intros/outros, b-roll, screenshots, music you have rights to use.
- Put everything in a shared folder with subfolders:
/brand,/broll,/screens,/audio,/exports. - Record where each asset is used (video + scene).
Avatars and personal avatars
Both platforms support avatar-led video and personal avatars, but you should assume you’ll recreate avatar setups.
- List which videos depend on a specific avatar identity.
- For any personal avatar/digital twin, document:
- Intended use (marketing vs training)
- Wardrobe/background expectations
- Do-not-use contexts (compliance/brand constraints)
- During the pilot, test one avatar style that matches your most common use case.
Voices and voice consistency
Both support voices and multilingual output, but voice catalogs and tuning differ.
- Document voice choice per video (and why): tone, pace, formality.
- Create a “Voice Spec” note:
- Target pace (slow/normal/fast)
- Preferred punctuation style for pauses
- Words that often mispronounce
- In Synthesia, recreate the closest voice match and record deltas you can’t eliminate.
Pronunciation guides (turn tribal knowledge into a file)
- Create a single pronunciation document:
- Product names, acronyms, customer names, industry terms
- Phonetic spellings and example sentences
- Include “don’t say it like this” notes.
- In the pilot, test your top 10 tricky terms and update the guide based on results.
Captions and multilingual versions
- Decide your caption policy: always-on vs optional; verbatim vs cleaned.
- For multilingual output, document:
- Who reviews translations
- Turnaround time
- Where approved text lives (outside the platform)
- For each pilot video, compare caption readability and timing expectations. If you need strict compliance, plan extra review time.
Templates and branding
Both support branding, but templates are rarely portable.
- Capture your current brand rules in a one-page “Video Brand Sheet”:
- Fonts, colors, logo placement, lower-thirds style
- Title slide pattern and CTA slide pattern
- Recreate one master template in Synthesia for the pilot.
- Don’t rebuild your entire template library until the pilot proves the workflow.
Hosted pages, embeds, and distribution
- List every place videos appear: website pages, landing pages, LMS, internal wiki, sales decks.
- For each location, note:
- Is it an embed, a link, or a hosted page?
- Who owns the page?
- Any analytics expectations?
- During the parallel run, avoid changing URLs for P0 videos. If you must, set up redirects or update pages in a controlled batch.
Integrations and automations
- Inventory integrations (even “manual integrations,” like a teammate uploading to an LMS).
- For each integration, write:
- Trigger (new video published)
- Destination (CMS/LMS/Drive)
- Owner and failure mode (what breaks when it fails)
- Rebuild only the one integration that saves the most time—or the one that causes the most pain when it fails.
Decision framework: which workflow fits which tool?
Use this as a conditional rubric (not a scorecard):
Prefer staying with HeyGen Creator if…
- Your work is primarily creator/marketing video with frequent iteration.
- You rely on flexible localization patterns and rapid variations.
- Your team is already trained and the main pain is not workflow structure.
Prefer moving to Synthesia Starter if…
- Your output is structured training/enablement/business video with repeatable layouts.
- You need clearer internal workflows for review, consistency, and reuse.
- You’re standardizing templates across multiple contributors.
If you’re unsure, keep both for one billing cycle and treat the pilot as your deciding evidence.
Reversible test (so you don’t get stuck)
Run this test on the 3 pilot videos:
- Rebuild in Synthesia using the same script and assets.
- Publish privately (or limited distribution) and collect feedback from 3–5 stakeholders.
- Change one variable at a time (voice, pacing, template) to see what actually matters.
- Compare rework causes, not just “which looks better.” Track: pronunciation fixes, caption edits, brand corrections, and approval rounds.
- Stop after 2 weeks and decide based on the evidence.
If the pilot fails, you still have HeyGen projects intact and your scripts/assets are now better organized for any future move.
Safe cancellation / migration checklist (do this before downgrading anything)
- Export/download final renders for all P0/P1 videos.
- Ensure scripts and source media live outside the platform.
- Save brand sheet + template screenshots + scene maps.
- Confirm who owns hosted pages and update embeds only after parallel verification.
- Document avatar/voice choices and pronunciation guide in a shared workspace.
- Pause new template creation for two weeks (avoid rework).
- Verify current pricing and plan terms before renewal changes: HeyGen — pricing and Synthesia — pricing.
For a structured side-by-side you can edit as your usage changes, use the main CTA: StackTrim comparison audit (costs and usage assumptions remain editable as your team’s volume, languages, and output shift).

Conclusion + renewal decision
A safe HeyGen to Synthesia migration is successful when your scripts and assets become platform-independent, your pilot proves the workflow, and you can switch without breaking distribution. Make this specific renewal decision: renew only one tool at the end of the two-week parallel run—renew Synthesia Starter if the pilot reduced rework in structured training/enablement videos, otherwise renew HeyGen Creator if marketing/creator iteration and localization flexibility remained your priority. Verify pricing again before you click renew.
