A 15, 30 or 60-second ad against each placement window
One generator in this register finishes an ad at a fixed length of 15, 30 or 60 seconds rather than returning clips to assemble. Against the published placement windows, all three lengths fit the non-skippable, in-feed, Shorts and TikTok placements; none fits a bumper. As of 2026-10-13.
| Item | What is published | Detail |
|---|---|---|
| Bumper | 5 to 6 seconds, non-skippable | None of the three lengths fits |
| Non-skippable in-stream | 60 seconds or shorter | All three fit |
| Skippable in-stream | Skip after 5 seconds; a view charged at 30 seconds or the end | A 15 is paid when it finishes; a 60 is paid at the 30-second mark |
| Masthead, desktop | Autoplays without sound for up to 30 seconds | A 15 or 30 autoplays through; a 60 autoplays its first half |
| In-feed | Charged on a click, or on 10 seconds of autoplay | All three; the opening 10 seconds carry the charge |
| Shorts | A view at 10 seconds or the end | All three |
| TikTok in-feed | Up to 10 minutes | All three fit |
Inclusion rule. Placements whose length limit or billing point appears on the platform's own help page, set against the three finished lengths one generator publishes for ads. Clip ceilings are a different unit and are kept on their own pages. Order. YouTube formats in the order the help page lists them, then TikTok.
1A finished length is a different unit from a clip ceiling
Most rows on this site's tool sheets are clip ceilings: how long one generation may run, usually somewhere between five and thirty seconds. An ad is assembled from several of those, so matching a tool to a placement normally means counting clips and planning joins.
One generator publishes the other unit. Its ad product finishes at 15, 30 or 60 seconds including an end card, and the length is a menu choice that moves the price. That makes the placement match a single comparison rather than a piece of arithmetic.
2The bumper is the window that needs a cut-down
Five to six seconds is shorter than the shortest finished length here by a factor of two and a half. A bumper therefore has to be cut from a longer master, which is how bumpers are usually made anyway, and the cut is an edit decision rather than a generation setting.
Every other YouTube format on the help page accepts all three lengths, and TikTok's ten minute ceiling is not a constraint at this scale at all.
3Where the charge lands decides which length is cheapest to run
A skippable view is charged at thirty seconds or at the end, whichever comes first. A 30 and a 60 are therefore charged at the same point; the 60 simply keeps playing for viewers who stay. A 15 is charged only when it finishes, so its charge arrives sooner and more often.
In-feed and Shorts move the point earlier still, to ten seconds or a click. Under those rules the opening seconds carry the cost of every length, which is an argument for spending the generation effort on the first shot rather than on the last.
