Mid-roll ad break finder

Breaks where the talking stops, not mid-sentence.

YouTube says ad breaks work best at natural moments, like a pause, and that breaks mid-sentence or mid-action are less likely to show an ad at all. Drop in your video and this listens for the pauses, then picks the best one near each point you want a break, preferring your chapter starts. The video never leaves your browser.

Only its audio is read, in your browser. Nothing is uploaded.

A break about every

Your chapters (optional)

YouTube doesn’t set how often; fewer breaks annoy viewers less. Chapters help: a break where the subject changes is the most natural of all.

What YouTube says

Mid-roll ads are for monetised videos of 8 minutes or longer.
Breaks at natural points, a pause in the audio or a change of scene, work best; mid-sentence or mid-action ones are less likely to show an ad.
No break is guaranteed to show an ad, and YouTube Studio marks the ones it thinks unlikely in red.

It doesn’t say how many breaks to have or how far apart; that’s your call.

How the pauses are found

It measures how loud your video is every tenth of a second and looks for moments that drop well below the speech around them for at least four tenths of a second. That works with a music bed under your voice, as long as the music sits well below it; when the music is nearly as loud as the voice, the gaps never go quiet and it says so. It listens only: scene changes in the picture aren’t detected, which is what your chapters are for.

How a break is picked

Near each point you asked for, a pause at a chapter start comes first. Otherwise longer pauses are cleaner cuts, but a pause loses a second of credit for every fifth of your spacing it is away from the point, so the breaks keep the rhythm you chose: at 5-minute spacing a 2-second pause 10 seconds off beats a short one right on the mark, and a short pause 5 seconds off beats a long one 2 minutes early.
