How to Generate an SRT Subtitle File for YouTube

Generate subtitles from your audio or video file, download SRT, review the cues, and upload the file through YouTube Studio's subtitle workflow. An SRT file supplies selectable captions; it does not permanently draw text onto the video.

Use a file you can actually upload

SceneDub's subtitle generator takes a media file, not a YouTube watch URL. Use your original recording or another copy you are allowed to process. A transcript without timestamps is useful for reading, but a caption upload needs timed cues. Start with the SRT generator when the desired final artifact is explicitly a SubRip subtitle file.

Finish the subtitle draft

Recognition and caption grouping are a starting point. Review names and terminology, entrances and exits, and places where two speakers overlap. Check short, dense cues with the reading-speed tool. If you edit plain transcript text, also inspect the downloaded caption file: fine cue editing belongs in a subtitle editor. Accessibility may require meaningful sound descriptions and speaker identification that automatic speech recognition does not supply.

Check the result after publishing

YouTube documents supported caption file formats, including basic SRT. Choose the correct video and caption language in Studio, then use the file-upload option. Preview the beginning, middle, and end after import. If captions appear at a constant delay, shift the subtitle file. If the delay grows, confirm that the captions and video come from the same edit.

The workflow

  1. Generate captions from the original media and download SRT.
  2. Review wording, timing, and reading speed in the subtitle draft.
  3. Upload the reviewed file to the matching video's subtitle track.

Input / starting point

interview.mp4

Output / result

interview.mp4 + subtitles.srt

The source video remains separate. A player or editor renders the subtitle track; creating an SRT file alone does not add visible text to the video pixels.
