Reels-specific rules the generator handles for you
Instagram's UI eats screen space: username and audio at the bottom-left, action buttons down the right edge, progress bar at the bottom. Captions placed in the bottom 15% or right 12% of the frame get covered. The Reels presets position text in the vertical center-lower band that stays clear.
Reels are also rewatched in loops, so caption pacing matters more than on YouTube — shorter lines with faster cuts outperform paragraph-style subtitles. The generator splits long sentences into loop-friendly beats automatically, and Hindi/Hinglish captions follow the same safe-zone and pacing rules.
Indian scripts, rendered properly
English, Hindi, Hinglish, Tamil, Telugu and 50+ more — all styled correctly in vertical format.

Frequently asked questions
Why not just use Instagram's built-in captions?
Instagram's auto-caption sticker has limited styles, no word-level animation, and weaker support for Hinglish and Indian languages. Burned-in captions look the same on every platform you cross-post to.
Does it handle the Reels safe zones?
Yes — presets keep text clear of the username, audio row, right-side buttons, and progress bar automatically.
Can I turn a landscape video into a captioned Reel?
Yes. Reframe 16:9 footage to 9:16 with the speaker tracked in frame, then caption and export.
What length works best?
Reels up to ~90 seconds caption in a single pass; the sweet spot for retention is usually 15–45 seconds with captions on every spoken line.
