- visit capsai auto subtitle generator
go to https://capsai.co/auto-subtitle-generator in your browser - upload your reel or short
click upload video to select your mp4 file or paste your instagram/tiktok/youtube short url - choose your subtitle language
from the language dropdown select the language you want (for example hinglish, hindi or english) - start the auto-generation process
click generate subtitles and wait a few seconds for capsai’s ai to transcribe and time‑sync your captions - review and refine in the editor
use the inline editor to correct misheard words, adjust punctuation, split long lines at natural pauses, and ensure each caption stays under two lines - fine‑tune timing for perfect sync
drag the start and end handles on each caption to align precisely with the spoken audio or key visual moments - customize styling if needed
if you plan to burn‑in captions, tweak font size, color, and add a semi‑transparent background or outline so text remains legible on mobile screens - export your final output
choose download srt to get a standalone subtitle file or select burn into video to export an mp4 with embedded captions - upload to your preferred platform
for instagram reels and tiktok use the burned‑in mp4; for youtube shorts upload the srt under subtitles in youtube studio - preview and publish
watch your captioned reel or short on both ios and android to confirm timing, readability, and placement before sharing with your audience
