Subtitle Editor

The primary workspace for proofreading subtitle text, adjusting timecodes, and previewing video output.

Overview

The batch subtitle editor is your main workspace for proofreading and editing subtitles. Here you can edit subtitle text line by line, adjust timecodes, preview the video with subtitles, search and replace, and perform batch operations.

Opening the Editor

In the media library, click the "Open Subtitle Editor" button on the right side of a video entry, or click the link in the notification after a task completes.

Interface Layout

The editor interface is divided into three main areas:

Left — Video list: Displays all videos in the media library. You can filter by "All Videos" or "Flagged".
Center top — Video player: Preview the video with subtitle overlay.
Center bottom / Right — Subtitle editing area: Shows all subtitle entries for line-by-line editing.

Subtitle Display Modes

The "Subtitle Mode" dropdown in the top toolbar lets you switch subtitle display:

Source Language: Show source-language subtitles only
Target Language: Show target-language subtitles only
Bilingual (Default): Show both source and target language
Subtitles Off: Hide subtitle overlay

Editing Subtitles

Click directly on any subtitle text to edit it. Changes are saved automatically. You can also click "Save Subtitle File" to trigger a manual save.

Tip Clicking a subtitle entry automatically seeks the video to the corresponding timecode, making it easy to verify that the timing is accurate.

Searching Subtitles

Click the search icon or press Cmd + F to open the search box. Enter a keyword to highlight matching subtitle entries. Use ↑ / ↓ or Enter / Shift + Enter to jump between matches.

Multi-Select Operations

Hold Shift or Cmd and click subtitle entries to multi-select. Once selected, you can:

Right-click Delete All
Right-click Merge
Click the "Re-recognize" button to re-run speech recognition on the selected subtitles

Title Generation

Click "Generate Title" to automatically generate 3 title suggestions based on the subtitle content. You can also use "Generate Titles for All Videos" for batch processing.
