Synthesia, the UK-based AI startup valued at $4 billion, is redefining video production through synthetic media. Founder Victor Riparbelli envisions a future where businesses create professional videos using AI avatars instead of traditional filming, slashing costs and time.

The platform’s tools already enable users to generate presenter-led content by typing scripts, with AI handling visuals and voiceovers. This shift could democratize video creation, allowing small enterprises to compete with larger budgets while raising questions about authenticity and job displacement in creative industries.
