Your deliverable deserves
a second pair of eyes.
Signoff scans your video exports for rogue frames, black frames, audio clips, and lower-third inconsistencies. Automatically, before anything goes to a client.

What it catches
Four automated checks that run on any export.
Black frame detection
Catches unintended black frames that slip through: a dropped frame at a cut, a missing handle, a render glitch.
Rogue frame detection
Uses machine learning to identify frames that don't belong: flash cuts, encoding artifacts, stray color mattes.
Audio clip detection
Flags sustained peaks that breach the digital ceiling. The kind that distort playback and get flagged in client review.
Text inconsistency scan
Compares every lower-third appearance against itself. Catches misspellings, position drift, and capitalization errors across the full timeline.
One-click timecode copy
Every flagged timecode in the report has a copy button beside it. Click it, switch to Premiere, Resolve, or Avid, and paste directly into your timeline to jump to the exact problem frame.
A real report, for a fictional video
This is what Signoff actually produces: a scrollable HTML report with clickable timecodes and thumbnail previews for every flag.
Everything stays on your machine
Signoff processes your video entirely locally. Your footage, its metadata, and every frame it analyzes never touch a server. Not ours, not anyone's. The app runs fully offline once installed.
The output report opens in your browser, but it is simply an HTML file written to your local drive. There is no upload, no cloud sync, and no account required.
No account. No password. No "sign in with Google." We know — it's a dying breed. You're welcome.
Built for editors, not broadcast facilities
Enterprise QC tools are powerful and priced for teams with dedicated operators and IT departments. Signoff is for the editor working alone the night before delivery.
Signoff doesn't replace enterprise QC for broadcast delivery. It fills the gap for everyone who needed something like that but couldn't justify the price.
"I built Signoff because I know how frustrating it is to deliver a polished piece of work and then get a note about a lower third typo in the first minute. So much effort goes into editing a video. One rogue frame or misspelling can give the client the impression you were being careless. Signoff exists so that when eye fatigue begins setting in, these types of errors don't slip through the cracks."
