Fast prompt exploration

Use a six-second 720p pass to compare motion language, composition and subject behavior before committing to a higher-resolution or longer render. Keep each variant tied to one measurable change.

Native high-resolution tiers

Text and image generation can move through 720p, 1080p, 1440p and 4K. The higher tiers and high frame-rate choices have shorter duration ceilings, so review the active constraints before queuing.

Image-led movement tests

Animate a trusted opening frame and optionally guide the ending frame. Describe camera motion and physical change rather than restating the source image as a new composition.

Source-audio performance

Audio-to-video requires a private source-audio asset and can optionally use an image. The canonical quote uses server-validated input-audio duration, never an invented output duration supplied in editorial copy.
