Video to Subtitle

Paste a video link or upload a video — the audio is extracted automatically and turned into SRT/TXT subtitles.

🎞️ Video Input

Video URL

Supports direct video links and major video platforms. Only the audio track is fetched server-side (about 1/10 of the full video size).

Pipeline: server-side audio extraction (16kHz mono, ~0.5MB/min) → AI speech recognition → result. The video is deleted right after extraction; please wait for the task to finish.
