Subtitle Editor: Cue Tools

This subtitle editor puts an audio waveform under your video and autosaves changes to an edit journal, helping you place cues and return to saved work.

▶ PLACE CUES ON THE SOUND
• Attach a video to see its audio waveform beneath the preview. Drag the selected cue edges, tap to move the playhead, and pinch or use Zoom in and Zoom out to inspect a section.
• Use Set in here and Set out here to place cue boundaries at the playhead. Move the start or end by one project-frame step for smaller adjustments.
• Read the active subtitle over the video in a plain-text preview, then edit the words in wrapped, multi-line fields.

▶ AUTOSAVE AND RECOVER EDITS
• Changes are saved to a project edit journal. If an interrupted session leaves journal edits to recover, the next launch offers Restore or Keep saved version.
• Watch the Saved, Saving and Not saved status. A failed save keeps the current edits available for Retry.
• Undo and Redo keep up to 50 steps. Text input is grouped so a typing sequence does not use a separate step for every letter.
• Quality checks flag overlaps, fast reading, short or long cues, and small gaps. Tap a result to jump to its cue; adjust the reading-speed and duration limits in Quality checks.

▶ REPAIR TIMING AND WORDS
• Shift all cues by a millisecond offset, use Two-point resync to align two subtitle and video anchors, or Convert FPS to change timing between frame rates.
• Find and replace ignores letter case and diacritics. See the match count, jump to a matching cue, or use Replace all.
• Add cues, edit start and end times, and manage named projects from Projects.

▶ WORK WITH SUBTITLE FILES
• Import and export SRT, VTT, ASS, SSA, MicroDVD SUB and SBV subtitle files.
• Choose an encoding and inspect a decoded preview when imported text needs another character set.
• Export subtitles, then Share or Save to folder. Exports are created in the app cache; copies you share or save elsewhere are kept where you put them.
• Back up projects with their subtitle sources and attached media in a manifest and ZIP parts. Restore backup parts to merge them with existing projects.

▶ GOOD TO KNOW
• Subtitle imports are limited to 8 MiB. Exports use UTF-8.
• Preview shows plain text, without rendering subtitle styles. ASS and SSA styles, event metadata and inline tags are preserved when exported in the same format; internal tag timing is not rescaled. Changing formats can discard styling and metadata.
• Frame steps use the project FPS time grid; video frames may vary. Some media cannot provide a supported audio waveform; subtitle editing remains available.
• Linked videos may need Relink video if the original moves, is deleted, or becomes inaccessible.
• Typing is saved after a short delay. Check Saved before leaving; edits that have not reached storage can be lost.
• Projects and edit history are stored in app storage. Analytics, diagnostic and advertising services may process usage and ad data.
