THE LAST TECHNICAL PASS

Before the handoff,
check the details.

Inspect subtitle timing, readability and your file checklist. Keep the decisions — and the files — on your machine.

01 / SOURCE

Subtitle files

SRT + VTT

Choose files from your device

Select multiple .srt or .vtt files. UTF-8 text recommended.

Up to 100 files · 5 MiB per file · 20 MiB per batch.
Invalid batches are rejected in full; nothing is silently skipped.

No files selected

Try a deliberately imperfect handoff.

Original fictional clips with a missing file, overlap, forbidden term and fast reading.

02 / EXPECTATIONS

Handoff checklist

OPTIONAL

Expected filenames

One filename per line, including its extension. Names match exactly apart from letter case.

Required terms

Forbidden terms

One term per line. Required and forbidden checks use literal, case-insensitive substrings in each file. Not word-boundary, contextual or linguistic certification. Blank lines are ignored; surrounding whitespace is trimmed.

03 / THRESHOLDS

Reading profile

EDITABLE DEFAULTS

Max. characters / second

CPS

Max. line length

chars

Max. lines / cue

lines

Min. cue duration

Max. cue duration

These are working thresholds, not a platform specification. Line length and line count must be positive whole numbers; other thresholds may be zero. Maximum duration must be at least the minimum.

Technical preflight.
Human review is still part of the handoff.

Ready when you are. Choose subtitle files or run the fictional demo.

Issue code

Technical issues in the selected subtitle files
Severity	Code	File / cue	Finding

The table shows at most the first 200 matching issues. Filters affect this table only. Downloads include every issue, including undisplayed rows, and are generated locally. A report with no findings is not certification.

KEEP THE SCOPE CLEAR

A technical check,
not a final sign-off.

This prototype does not compare subtitles with audio or video, certify translation quality, or guarantee universal delivery compliance. Automated text and timing checks can miss problems and flag intentional choices.

Review findings against the actual destination specification. Required terms can appear in the wrong context; literal matching cannot judge meaning.
