Questions About AI UGC & Video Captions?
See how UGC creation, references, on-video captions, and publishing work together inside The Post Engine.
Do I need to film myself to create UGC?
No. You can create UGC-style content without recording a traditional shoot yourself. The creation workflow lets you build the scenes and direction inside The Post Engine.
