Lineframe Subtitle QC

Check SRT & VTT Timing

$3.99 · Designed for iPad. Not verified for macOS.

Inspect subtitle timing and readability, refine cues, and share checked SRT or WebVTT files with a plain-text report. Lineframe checks the subtitle file you already have before it goes to an editor or a client. Open an SRT or cue-only WebVTT file from Files, or try the included sample, then review every cue in a focused cue list. Findings flag overlaps, out-of-order starts, invalid or very short timings, fast reading speed, long lines, and captions with more than two lines. Edit cue text and timestamps, shift the full track in 100 ms steps, or trim safe overlaps. Undo recent edits, shifts and trims during your session. Open files up to 5 MB and 10,000 cues, with timestamps below 100 hours. Lineframe keeps your imported projects and edits on this device. Share a checked SRT or WebVTT file and a separate plain-text inspection report when you are ready. The checks are practical guidelines, not a guarantee that subtitles will suit every audience or platform. Review the final timing against your video in your editing software. Lineframe does not transcribe speech, translate captions, process video, or upload files. No account, ads, subscription, analytics, tracking, or cloud sync.
