Add automatic subtitles to a video

Before you upload

Automatic subtitles work best when the uploaded video has clear speech and a normal audio track. If the audio is extremely quiet, distorted, or mixed under music, expect to spend more time correcting the transcript.

• Use the uploader warnings for current duration and format limits.
• Trim very long source files before uploading if you only need one clip.
• Keep a local copy of the original video until your final export is approved.

After generation

AI captions are a first draft. Review proper nouns, punctuation, speaker-specific wording, and fast sections before exporting.
