Fitting LTX-Video output into YouTube ad formats
The LTX-Video card publishes 30 frames per second at 1216x704, says the model works best below 257 frames, and states that frame counts must be divisible by 8 plus 1. Nothing on it is expressed in seconds, so the duration column on this row is a derivation rather than a quotation. As of 2026-09-22.
| Format | Generations needed | Note |
|---|---|---|
| Bumper, 5-6 s | One generation | 177 frames, because the count must be a multiple of 8 plus 1 |
| Non-skippable, up to 60 s | Seven generations | Worked from the frame guide, not from a stated length |
| Skippable, 30 s of paid view | Four generations | Same derivation, same caveat |
| Masthead, 16:9 up to 30 s | Not stated | 1216x704 is a pixel pair; no ratio is named |
Inclusion rule. Formats from Google's own help page, matched only against limits the tool vendor publishes. Where either side does not state a value, the row says so rather than estimating. Order. Shortest format first, as on the placements page.

2Length published in frames is length published in a different language
Every other entry in this register that says anything about length says it in seconds, because seconds are what an ad slot is sold in. This card says 30 frames per second and a working ceiling of 257 frames, which is about eight and a half seconds, and that conversion is arithmetic done here rather than a figure the vendor published.
The distinction is not pedantry. A figure quoted from a page can be rechecked when the page changes; a figure derived from two other figures inherits both of their assumptions, and in this case one of them is the phrase works best, which is guidance rather than a ceiling. The sheet therefore records the frame figures and marks the seconds as worked out.
3The divisibility rule is a real constraint on a six second brief
Frames must be divisible by 8 plus 1 and resolutions by 32, which means a round number of seconds is usually not reachable. Six seconds at 30 frames per second is 180 frames, and 180 is not a legal count; 177 and 185 are, giving 5.9 and 6.17 seconds. A bumper specified as five to six seconds therefore lands at 177 frames rather than at six seconds exactly.
That sounds trivial until a slot has a hard upper bound. Bumper is one of the two formats here with a stated ceiling, and a piece that overshoots it by a sixth of a second is a piece that has to be re-run rather than trimmed, because trimming generated footage takes the tail off the movement the shot was built around.
