Social video captions in ILLIXIS have two configuration dimensions: Caption Type (content angle) and Caption Style (visual presentation).

Caption Types

Choose the messaging approach for your video caption:

Type	Use When	Characteristics
Storytelling	Sharing narratives, behind-the-scenes, personal experiences	Emotional connection, narrative arc, relatable scenarios
Educational	Teaching concepts, explaining processes, sharing tips	Informative tone, clear explanations, actionable insights
Promotional	Announcing sales, promoting products, driving conversions	Direct calls-to-action, urgency, value propositions

Where configured: Video generation modal → Caption Type dropdown

Platform-specific: ILLIXIS automatically generates captions matching all three types when you create social extensions. Select your preferred type when generating video.

Caption Styles (Visual Presentation)

Caption Style controls how text appears on screen:

Word Reveal (Recommended for Voiceover)

What it does: Phrases accumulate as narrator speaks, synced to word-level timestamps from the voiceover
Visual: Uppercase text, semi-transparent black background, left-aligned
Best for: Videos with voiceover enabled
Tech: Uses word-level timing data from the voiceover for precise phrase sync

How it works:

Caption broken into natural phrases (3-5 words each)
Each phrase appears when spoken
Previous phrases remain visible (accumulating)
Text persists through entire video segment

Standard Caption Styles

When voiceover is disabled or you prefer static captions:

Style	Appearance	Use Case
Clean	White text on dark semi-transparent pill	High readability, professional
Bold Outline	Yellow text with thick black stroke	High contrast, attention-grabbing, sales content
Karaoke	Word-by-word highlight (bright green)	Engagement, lyric-style presentation

Display behavior: Captions rotate through sentences/phrases, one at a time (non-accumulating).

Configuration Examples

Example 1: Storytelling Video with Voiceover

```
Caption Type: Storytelling
Caption Style: Word Reveal
Enable Voiceover: Yes
Voice: Rachel
```
Result: Emotional narrative caption with phrases accumulating as voice speaks.

Example 2: Educational Video without Voiceover

```
Caption Type: Educational
Caption Style: Clean
Enable Voiceover: No
```
Result: Static informative captions rotating every 2-3 seconds.

Example 3: Promotional Video with High Impact

```
Caption Type: Promotional
Caption Style: Bold Outline
Enable Voiceover: Yes (optional)
```
Result: High-contrast yellow text for maximum visibility, promotional messaging.

Technical Notes

Word Reveal Requirements:

Only works with voiceover enabled
Requires voiceover to be enabled (provides word timestamps)
Caches voiceover audio to avoid regenerating on video edits

Caption Type vs Style:

Type = what the caption says (content angle)
Style = how the caption looks (visual design)

Phrase Extraction:

Natural phrase boundaries detected automatically
Minimum 1.5s per phrase (readability)
Maximum 4.0s per phrase (engagement)
Timing adjusted based on voiceover duration

Caption Caching:
If you regenerate a video without changing the caption text or voice, ILLIXIS reuses the cached voiceover audio for faster processing.
