Does clip length depend on the resolution?
For some vendors, yes. Google Veo requires 8 seconds at 1080p and 4k, and Vidu's range depends on the model, 1 to 16 seconds on q3 and a fixed 5 on q1. From 2 source pages, read 2026-09-25; no maker pays to be listed.

2What it means for delivery
Where length and resolution are tied, the choice of one limits the other. Checking both figures together avoids planning a long 4K shot a model cannot deliver.

3The production side of the spec
For a delivery question like “Does clip length depend on the resolution”, SceneMixer states the following about what it produces:
Video is 16:9 landscape by default, with 9:16 vertical available; you set it once per project. Segments are typically 4 to 15 seconds, and some model tiers go to 30.

Sixty to a hundred and twenty seconds is the working range for short drama, and that is what the outline paces for. A 90-second episode is typically seven segments of about fourteen seconds stacked together.
