Why Eight Seconds
How it worksClip length is what the model renders in one pass.
The clip is the unit
Most video models render five to ten seconds per generation. A sixty second piece is not one render, it is eight of them.
60s ÷ 8s = 8 shots
Remainders cost a whole clip
A four second tail still consumes one full generation. Rounding the runtime to a clean multiple is usually cheaper.
61s → 9 renders, not 8
The first two seconds
Short-form retention is decided before the first clip ends. Shot one carries the hook, not shot two.
Hook = 0.0 – 2.0s
Even cuts read as flat
Identical shot lengths make the edit feel mechanical. Vary a few by a second or two once the grid is set.
Vary ±1–2s
Questions
03Which clip length should I use?
Match it to the model you are generating with. Eight seconds is a safe default for current video models.
Does the remainder have to be a separate shot?
No. You can absorb it by stretching the other shots, which the table shows as an even split under the shot-count mode.
Is this tied to any particular tool?
No. It is plain arithmetic on runtime and clip length, so it works for any generator.
