How to drop an ad into a podcast at a natural pause
Give Vizard Agent the episode and the ad and say roughly where it should go. It looks for a point that is both a change of subject and a genuine pause, matches the ad's loudness to your speaking voice, trims the silence off its ends, joins it in and then has both transitions listened to rather than assumed.
What do you type into Vizard Agent?
Ask Vizard Agent for a natural break rather than for a time. A time is easy to satisfy and usually wrong. A natural break is a condition the transcript can actually be searched against, and a rough window such as the first forty-five minutes narrows the search to where an ad is worth anything.
Prompt
What does Vizard Agent actually do?
It treats the spot as the whole decision. A pause on its own is a bad target, because people pause mid-sentence constantly. A pause that coincides with a change of subject is a place where a listener is already between two things, and an ad there costs almost nothing. In the session behind this article it:
- Looked at the ad file and viewed frames from it before deciding where it should go, in an episode that had already been cleaned up.
- Searched the first 45 minutes for section changes that also had a real pause in them.
- Measured the loudness of the user's speaking voice and of the ad, and checked the ad's start and end for dead air to trim.
- Rendered the two halves of the episode and the level-matched ad at the same time, so the long episode wasn't encoded twice, then joined the pieces.
- Cut out the transition region, uploaded it, and had both transitions listened to rather than assumed.
- Exported the mp4 and the mp3 from the same master, so they cannot disagree.
When does this not work well?
Some episodes do not have a good break. A continuous interview, a tightly edited narrative or a conversation that never changes subject will force the ad somewhere that costs more, and it is better to know that than to have one inserted anyway. Music underneath throughout makes the join audible, and an ad with its own bed is harder to level-match.
Common questions
Can it find the spot itself? Yes. Vizard Agent searches the transcript for a section change with a real pause.
Will the ad be louder than me? Not once matched. Vizard Agent measures both.
Why not just use the longest pause? It's often somebody thinking mid-sentence. Vizard Agent looks for a change of subject instead.
