Know exactly what was checked.

Technical checks on your exported files.
Clear findings for the decisions only you can make.

Full decode

Check the primary video and all audio tracks for decode errors.

Black & quiet intervals

Flag dark frames and quiet stretches for human review.

Loudness & true peak

Measure LUFS and true peak on the primary audio track.

SRT timing

Check syntax, overlapping cues and timing beyond the video.

Supported in this beta

MP4 with H.264 8-bit SDR video and AAC audio. UTF-8 SRT subtitles up to 10 MiB. Batch import up to 50 videos per project, with matching-name subtitle and cover pairing.

Coverage stays visible

Full check adds decoding and signal analysis. Quick check covers metadata, required files and subtitles. Skipped, failed, unsupported and stale checks remain visible in the report.

You make the call

Black and quiet intervals can be intentional. Confirm faults or accept non-blocking exceptions with notes. Cover checks verify file presence only. Audio quality analysis uses the primary track.

What is outside the current detection scope?

HEVC, HDR and ProRes are outside this beta’s supported analysis. CutCheck does not check factual or editorial accuracy, subtitle meaning, copyright, or audio/video synchronization. A completed check is not a guarantee of platform acceptance or error-free content. Fixes are made in your existing editor, then checked again with replacement files.

The Mac app runs the checks; this demo lets you inspect the evidence.

Three findings to review

Choose a finding to jump to its timestamp.

A dark interval is a review candidate. Is it an intentional pause or a missing picture?
