Use Cases

When a video lacks a subtitle file but subtitles are desired during playback.

Note: You can enable automatic publishing of smart subtitles in System Settings > Video Settings. Once enabled, subtitle tasks will be published automatically upon creation, without requiring manual review and publication.

Select Video File

Select a video file by searching or by choosing a video category. When the auto-publish toggle is on, smart subtitles will skip the review step and be published directly.

Review Subtitles

Once a subtitle task is created, the system processes the video and outputs a subtitle file. Typically, you can preview the subtitle effect by reviewing the subtitle content.

Notes:

  1. You can globally enable automatic publishing of smart subtitles in System Settings > Video Settings. When creating subtitles, auto-publish will be set by default.
  2. If you need to modify subtitle content after publication, you can re-review the subtitle content and republish it.
  3. If the video contains a large number of specialized terms and the current smart subtitle content is inaccurate, please contact us.
  4. Currently, only Chinese videos are supported. If you need subtitles for other languages or dialect videos, please contact us.
  5. The time from creating a subtitle task to automatic publication is generally within 5 minutes. For videos longer than 60 minutes, the average time is around 10 minutes.
