VidStitch AI
What do I need to use VidStitch AI?
- SRT file - Your timed script/subtitles

How does AI find visuals?
The AI: 1. Analyzes your script for key concepts 2. Generates targeted search queries 3. Finds relevant videos/images from the web 4. Scores and selects the best matches
Why are visual matches poor?
Likely causes: - Script is too vague or abstract - Topics are too obscure - Missing proper nouns (names, places, dates)
See Writing Effective Scripts.
What's the maximum script length?
24,000 characters maximum.
Can I use my own visuals instead?
VidStitch AI sources visuals automatically. For manual visual control, use the B-roll Clips workflow.
B-roll Clips
Can I use YouTube videos as B-roll source?
Yes! Enter a YouTube URL instead of uploading a video file.
How do I adjust AI suggestions?
On the timeline: - Approve ✅ to keep a suggestion - Reject ❌ to remove it - Click to edit timing, trim, or select different clip
What are content types for?
Content types (Documentary, TV Show, Sermon) optimize AI analysis for different pacing, imagery, and placement strategies.
Can I add clips manually?
Yes, use the "Add Marker" feature to specify custom insertion points.
V5 Story Maker
What does "clone" mean?
Cloning extracts the visual structure of a source video and recreates it with your script and voiceover—creating a derivative work, not a copy.
Can I use any YouTube video?
Requirements: - Must be public (not private/unlisted) - Must not be age-restricted - Must not be a live stream
What's the source priority slider?
Controls how closely the AI follows the source video: - 50%: More freedom to find alternatives - 90%: Strongly prefer source video clips
