Synthesia
Synthesia turns a text script into a polished talking-head video using realistic AI avatars, widely used for corporate training and onboarding content.
What is Synthesia?
Synthesia was among the first companies to make AI video generation genuinely useful for enterprise training and communications. Founded in 2017 in London, it lets organizations create professional video content with AI avatars from a text script — no cameras, no studios, no scheduling actors. By 2024 the platform hosted over 200 AI avatars in 140+ languages and was used by more than 50,000 companies including major enterprises like Reuters, Zoom, and Amazon for internal training content. For L&D teams, a Synthesia outage doesn't just inconvenience a few users — it can block entire course production pipelines.
Rendering photorealistic AI video is among the most compute-intensive tasks in the AI industry. Each Synthesia video generation job requires GPU clusters to synthesize lip-sync, facial animation, and background compositing in real time, then encode the final output to the appropriate video format. The platform queues these jobs across its rendering infrastructure, which means demand spikes — particularly at end-of-quarter when training deadlines hit — can result in generation jobs sitting in queue far longer than normal. Synthesia's multi-language synthesis also requires separate model variants per language, adding complexity to its serving architecture.
When Synthesia is experiencing problems, users encounter: video generation jobs submitting successfully but never progressing beyond "processing," exports failing partway through rendering and returning an error without explanation, the video editor becoming unresponsive when switching between scenes, avatar preview playback not loading in the script editor, custom avatar uploads getting stuck in "training" status, and completed videos failing to play or download from the finished project library.
Outage.gg tracks Synthesia platform status in real time. If your video generations have stalled, checking the live status page can quickly confirm whether it's a rendering queue issue affecting everyone or an isolated problem with your project.
