Source coverage: standard. Reviewed 10–12 sources. Using the 5 strongest. In practice, Synthesia performs very well for fast, repeatable business video production. Avatar quality, voice options, scene templates, and translation workflows are mature enough for real team use, and collaboration features make it easier to keep content consistent across departments. The main limitation is creative flexibility: users who need deep timeline editing, highly custom motion design, or film-style storytelling will hit the edges of the platform sooner than they would in a traditional editor.
