Dead-air and retake checker for talking-head clips
Last updated: 2026-11-03
Upload a talking-head clip of up to 3 minutes. No account needed. The checker runs Cutora AI's first cut on it and shows you how much of the clip is pauses, how many pauses are longer than 0.7 seconds, which takes were repeated and where you started a sentence and stopped, each with its time in your clip, and a 30-second preview of the first cut.
Check a clip
No account needed. Up to 3 minutes. The clip is deleted 24 hours after you start.
What the checker measures
A pause counts when the sound drops out for more than 0.7 seconds between two words. The checker adds those pauses up and shows them as a share of the clip, so you can see whether a few long gaps or many short ones make up the dead air.
A repeated take is a line you said more than once, a restart is a sentence begun again, and a false start is a few words you began and dropped. The checker lists each one with the time it starts in the clip you uploaded. It shows the kind and the time, and it does not copy your words onto the page.
These are the same findings the first cut in Cutora AI works from. The checker only reports them: your clip is not changed, and a pause is not a mistake. A short pause can be a breath before a point.
What you get back
You get the number of pauses over 0.7 seconds, the seconds they add up to, the share of the clip, a list of pauses and takes with their times, and a preview of the first 30 seconds of the first cut with a Cutora mark. The preview shows what the first cut does with your clip.
The full first cut and the export need an account. The trial takes one video of up to 10 minutes.
What happens to your clip
Your clip goes through the same steps as a project in Cutora AI: it is prepared, its speech is transcribed and its pictures are described by AI services, and the first cut is built from that. We do not use your videos to train AI models.
The clip, its transcript, the notes made from it, the preview and the results are deleted 24 hours after you start the check. You do not need to do anything to make that happen. The checker keeps no account for you, and it stores no email and no name.
To count the clips from one connection in a day, the checker keeps a code made from the connection's address and the date. The address itself is not stored, and the code cannot be followed from one day to the next.
Limits
A clip can be up to 3 minutes. Each connection can check 2 clips a day. The checker takes 50 clips a day in all and switches off for the rest of the day when it has used its daily allowance, then comes back at midnight UTC. A file can be MP4, M4V, MOV, WebM or MKV.
The checker works on one person talking to camera, recorded in one session. A recording with several speakers, or one that is mostly slides or a screen, is outside what it is built for, and its numbers should not be relied on.
What it does not do
It does not cut, change or return your clip, and it does not count filler words. It does not tell you how long editing would take, and it makes no promise about how much a first cut shortens a video: that depends on the video.
To find only the long pauses of a recording, without uploading anything, use the Pause finder, which reads the sound in your browser.
Questions
Do I need an account to use the checker?
No. You choose a clip and the checker runs. The full first cut and the export need an account, and the trial takes one video of up to 10 minutes.
How long can the clip be?
Up to 3 minutes. A longer clip is refused before it is uploaded. Cut the part you want to check, or try Cutora AI on the whole video.
What happens to my clip?
It is processed like a project in Cutora AI and deleted 24 hours after you start the check, together with its transcript, notes, preview and results. We do not use your videos to train AI models.
What counts as a pause, a repeated take and a false start?
A pause is a silence of more than 0.7 seconds between two words. A repeated take is a line said more than once. A false start is a few words begun and dropped. The checker lists each with its time and does not copy your words.
Does it find filler words such as um and uh?
No. This report covers pauses, repeated takes and false starts only.
Why does the page say the checker is off or used up?
It takes 2 clips per connection and 50 clips a day in all, and it switches off for the rest of the day when its daily allowance is used. It comes back at midnight UTC.
