The short answer
Library Mode renders branded videos from footage you already have. Pick it when you have raw clips from a shoot, podcast, or event. Pick Twin Mode when you need new content without recording. Pick Hybrid to blend both.
When Library Mode wins
- You shot footage this week and want to ship 30 days of content from it.
- You want the content to feature you in real environments (gym, kitchen, office, on the road).
- You need to publish before you have time to record more.
- You want maximum authenticity vs. AI-rendered output.
When Twin Mode beats Library Mode
- You did not shoot anything this week and need to ship today.
- You need consistent content output during travel or illness.
- You want to localize content into other languages (Twin handles dubbing better).
When Hybrid wins
- Your shoot covered 4 topics but you want to ship 8. Library Mode handles the 4 you shot, Twin Mode fills the other 4.
- A video needs a closing line you forgot to record. Hybrid stitches your real footage with a Twin-rendered closer.
How Library Mode picks clips
When you submit a prompt, ENCORE searches your connected sources for clips that match the prompt context. It uses semantic search over clip captions and visual content. You can override the auto-pick by selecting specific clips manually.
