Synthesia's latest avatar quality crossed the B2B uncanny valley. For product explainers, sales enablement videos, and training content, it's now our default recommendation.
The 30-language scale cheat
Here's the move: record your founder or head of product once in English. Synthesia produces clean, lip-synced versions in 30+ languages — including the ones that usually get skipped in localization projects.
A B2B SaaS client we work with shipped 150 localized product videos in a week. Previous localized video projects had taken six months and required a vendor network in every region.
The quality bar that matters
Synthesia isn't going to win an Emmy. For a TV commercial, use real humans. For an internal training video or a 'how our product works' page, nobody will notice — or care — that the avatar is synthetic.
The threshold is this: does your audience need authentic emotional connection to the speaker, or do they just need accurate information delivered clearly? If it's the latter, use Synthesia.
The prompt-to-video pipeline
- Marketing writes a 60-second script.
- Brand compliance reviews for tone and messaging.
- Synthesia renders in 12 languages overnight.
- The loc team spot-checks 2 of 12 for accuracy.
- Ships next morning.
Synthetic avatars won't replace hero content. They will replace the 80% of B2B video nobody watches because it doesn't exist in their language.
