Synthesia, researched.
Manual scene and brand editing on the platform. Overall verdict withheld. Explore the findings, limitations and 15 cited sources below.

What the evidence supports, criterion by criterion
3 of 11 applicable criteria have enough accepted evidence to say something. The rest are listed below them, unscored.
| Criterion | Evidence | What we found |
|---|---|---|
| Workflow and editability | Limited evidence | Manual scene and brand editing is useful at platform level.Platform workflow transfers cautiously; avatar-specific edit controls may differ. |
| Output specifications and delivery | Moderately supported | Export is documented as MP4 at 1920×1080, with stock-avatar counts rising by tier from 9 on Basic to 240+ on Enterprise. Express-3 avatars are documented as a staged rollout.Those counts are not Express-3 counts, and tier-specific Express-3 availability is not published. |
| Pricing and value | Moderately supported | Monthly pricing is documented: Basic free with 10 minutes, Starter $29 with 10, Creator $89 with 30. Credits are defined at 2 per second, or 120 per finished minute.The annual figures do not reconcile — the pricing cards and the FAQ disagree — so no annual price is published here. Credits also fund non-video features, so an allowance is not a guaranteed minute count. |
