The tool utilizes advanced speech recognition algorithms to extract audio, split timestamps precisely, and generate synchronized SRT subtitles.

4. Bilingual Captions & Style Customization
Switch between original, translated, or bilingual subtitles with live preview. Adjust font size, color, stroke outline, background box, and alignment.
5. Export Subtitle Files
In addition to rendering videos, export your reviewed subtitles as standard SRT (.srt), Markdown (.md), or plain text (.txt) files for backup or external editors.
6. Render and Export Video
Burn subtitles into your high-definition video locally on your device. Once rendered, preview, save to Photos or Files, or share directly to TikTok, YouTube, and Instagram.
