What is an AI Video Generator?

add
An AI video generator is a tool that automatically turns your idea or script into a fully produced video complete with visuals, voiceover, and editing without needing a camera or editing software. ByThen takes it further by handling the entire workflow in one place: script, key visuals, storyboard, voiceover, and editor tool.

Do I need video editing skills to use it?

add
No. ByThen handles the generation and assembly automatically. The Editor Tool gives you controls to make adjustments, but the heavy lifting, scripting, visual generation, scene building, is all done by AI.
