Synthesia review
Avatar video for training and internal communication, without a camera or a studio.
Editorial verdict: Efficient for training video in many languages, and no substitute for real film production.
Synthesia solves a very concrete problem: company videos that have to be updated regularly. Instead of booking a studio you write a script, choose an avatar and a language, and a few minutes later you have a video that can be regenerated in minutes at the next process update.
The multilingual side is particularly valuable. Providing a training course in twelve languages used to be a budget item; here it is a dropdown. Templates and brand rules keep results consistent even with many authors.
The limit is credibility. Over two or three minutes it becomes clear that nobody is really speaking. For mandatory training and process videos that is bearable; for image films and anything emotional it is not.
