Understanding Chat Story Videos
Chat story videos are short-form narratives displayed as simulated messenger app chats. They differ from traditional videos by mimicking a sequential chat UI with:
- Animated text bubbles appearing with smooth transitions
- Character avatars and reaction emojis to convey emotion
- Sound cues (like “ding”) to signal new messages
- A familiar texting interface that boosts immersion
On mobile, vertical mode (9:16) fits full screen, making text legible and boosting completion rates by up to 75% compared to horizontal ads.
Real-world example: A mystery campaign saw a 30% jump in completion within 48 hours by switching to full-screen chat bubbles and timed message reveals.

Exploring the Optimal Format for Chat Story Videos
Aspect Ratio & Resolution
- Vertical 9:16 at 1080×1920 pixels (Full HD vertical) for TikTok, Instagram Stories, Snapchat
Frame Rate & Codec
- 30 fps for smooth bubble animations
- MP4 container with H.264 codec; H.265/HEVC for 30% smaller files
Design Tips
- Use template-based editors like Vidulk - Fake Text Message Story App for quick chat-bubble animation
- Minimum font size: 24 px; choose high-contrast text and backgrounds
- Keep avatars and emojis within the center 80% safe zone
Workflow Techniques:
- Build a chat UI style guide: fonts, bubble colors, spacing
- Animate entries with ease-in/ease-out timing (0.3 s appear, 0.5 s display)
- Preview on actual devices to catch cropping or alignment issues

Comparing Video Formats for Fake Chat Videos
Fake chat videos dramatize fictional threads. Here’s how formats stack up:
Vertical 9:16 (1080×1920)
- Pros: Full-screen immersion on TikTok, Reels, Snapchat
- Cons: Not ideal for YouTube standard feed
Square 1:1 (1080×1080)
- Pros: No black bars in Instagram and Facebook feeds
- Cons: Less vertical space; smaller text
Horizontal 16:9 (1920×1080)
- Pros: Standard YouTube format
- Cons: Chat bubbles shrink; readers must lean in
Vertical format delivers 10–20% higher story retention vs. square or horizontal. A comedy channel saw a 15% rise in completions and doubled shares by switching from 1:1 to 9:16.
