Yesterday afternoon a short video went out on every one of our social accounts. The picture was fine. The sound was not. Behind the music there were a few seconds of confident speech in no language anyone recognised.
I did not catch it before it went out. I found it myself that evening, scrolling our own pages, and the best description I could manage was that it sounded "chinese or something". A video about how deals get closed had gone to every account with a stranger muttering in the background.
How two checks still let it through
The clip came from an older batch of thirty, made weeks ago. That batch had been screened once by ear, and the clips with spoken lines were taken out. This one was missed. People are good at hearing speech. They are not good at hearing it in thirty clips in one sitting.
Newer videos went through an automated check for speech, and when I looked at it properly it had its own flaw. It was listening for English. It found nothing it understood and reported each clip as clean. The question it was asking was "is anyone speaking English?" when the question that mattered was "is anyone speaking at all?" Re-run the honest way, I could no longer say for certain that any of the recent videos were silent behind the music.
Both checks did exactly what they were built to do. Neither was built to prove the thing I actually cared about.
What we changed
We stopped trying to detect bad audio and removed the possibility instead. From yesterday, every video ships silent. Whatever sound a video arrives with is stripped before it goes anywhere, and nothing is uploaded until the file itself confirms it carries no sound at all. The words that matter are on screen, typed exactly and read back frame by frame.
Then we went through everything still waiting to go out. Three more clips from that older batch had audible speech in them. They were deleted before they could run.
It took less than an hour. The part that stung was not the fix. It was that a check had been reporting "clean", and I had believed it.
Why this matters to a business that is not making videos
Every business has a version of this. A step that is supposed to happen, a person who usually does it, and a report that says it was done. The invoice that gets checked by whoever is in the office. The quote that someone always double checks. It works until the day that someone is off, busy or tired, and nobody notices the check did not really check.
The fix is rarely more care. It is moving the check out of somebody's memory and into the system, so it runs the same way on a Sunday as on a Tuesday, and so it cannot report success unless the thing it guards is actually true.
That is most of what a Business Operating System is for. Not more software. Fewer places where "it's handled" is a guess.
If you suspect a few of your own checks are guesses, a free Business Autopsy is where we find them.
Frequently Asked Questions
What went wrong with the video?
A short video posted on our social accounts carried a few seconds of meaningless speech behind the music. It came from an older batch screened by ear, and our automated check only listened for English.
What changed afterwards?
Every video now ships with no sound track at all, and upload is refused unless the file confirms it is silent. Three more affected clips were found and deleted before they ran.
What is the lesson for other businesses?
A check that depends on a person remembering, or that asks the wrong question, will eventually report success when it should not. Put the check in the system, and make it prove the thing it guards.
