- Start with clear audio: Speech recognition works best when voices are clear and background sound is limited.
- Generate a timed transcript: Upload the video or use a supported public URL and choose the spoken language.
- Correct the subtitle text: Check names, punctuation, numbers, and line breaks before creating the final video.
- Translate when needed: Review the original transcript before translating so errors do not carry into another language.
- Choose readable styling: Use strong contrast, a sensible font size, and an outline or background when the footage is visually busy.
What makes subtitles easy to read?
Good subtitles are not only accurate; they are comfortable to follow. Long lines, rapid changes, weak contrast, and poor timing make viewers work harder than necessary.
Keep the text concise without changing the meaning. Break lines at natural phrase boundaries. Position and style subtitles so they remain visible over both bright and dark scenes.
- Prefer short, complete phrases over dense blocks of text.
- Use high contrast between text and the video.
- Keep names and technical terms consistent.
- Check timing by watching the final result from start to finish.
Automatic subtitles still need review
AI subtitle generation saves substantial time, but it cannot know every name, acronym, or intended meaning. A short review usually produces a much better result than publishing the first transcript unchanged.
Pay special attention to the opening minute, speaker changes, sections with music, and any sentence that sounds unusual. These are common places for recognition errors.
