What You Can Do

This skill analyzes broadcast subtitles to identify timing errors, formatting violations, grammar mistakes, and readability issues. You provide subtitle files and receive a detailed QA report pinpointing every problem—from sync overlaps to character limit breaches—so you can fix them with confidence before broadcast delivery.

Features

Timing & Sync Validation

Detect overlapping subtitles, timing gaps, and synchronization issues that will cause playback problems.

Grammar & Spell Checking

Catch typos, grammatical errors, and language inconsistencies across all subtitles in a single pass.

Format Compliance

Verify character limits, line breaks, duration requirements, and formatting standards specific to your broadcast platform.

Readability Analysis

Ensure subtitles are readable at broadcast speeds—check for excessive text density, proper line breaks, and visual balance.

Consistency Checking

Validate terminology consistency, speaker name formatting, and style rules across all subtitle entries.

Batch Processing

Handle multiple subtitle files simultaneously and compare them for consistency across episodes, languages, or versions.

Localization Review

Verify cultural appropriateness, regional terminology, and that translations maintain timing and meaning from the source.

Compliance Scoring

Get a pass/fail assessment with a compliance percentage so you know exactly what needs fixing before delivery.
