Positioning Burned-In Subtitles & Captions
Check that dynamic word-by-word captions sit above the bottom 420px caption/audio deck and to the left of the right-hand engagement column.
Reel Safe-Zone Checker
Never publish a vertical video only to discover your burned-in subtitles are hidden behind the caption text or your call-to-action is blocked by the Like and Share buttons. Upload a 9:16 video frame or graphic to preview authentic Instagram Reels, Instagram Stories, and TikTok UI overlays before you export your final edit.

Technical Specifications & Best Practices
- ✓On a standard 1080×1920 (9:16) canvas, avoid placing critical text in the Top 220px (11.5%), Bottom 420px (22%), or Right 140px (13%).
- ✓If your Reel also plays in the main Home Feed without being tapped full-screen, Instagram initially displays the center 4:5 region (1080×1350).
- ✓Different smartphone aspect ratios (e.g., 19.5:9 vs 16:9 phones) may slightly crop the left/right 35px edges.
- ✓100% client-side preview—your unreleased video stills never leave your browser.
