Motion-Brush Trajectory-Controlled Image Animation

Properties

family

image-to-video

modality

static image + hand-drawn motion paths -> per-element trajectory video

whyMultiModel

Region selection/masking and trajectory-path encoding are handled by a separate interactive control layer distinct from the underlying video generator; the diffusion backbone alone has no mechanism to accept per-object drawn paths without an intermediate trajectory-to-motion-field encoder.

steps

[object Object], [object Object], [object Object]

controls

brush-selected motion regions (up to 6), hand-drawn trajectory curves per element, static-lock brush for background, optional text prompt for action description

useCases

[product shots with a single element (e.g. bottle cap, fabric) animated in place][cinemagraph-style social ads][explainer graphics where only an icon/arrow should move]

pitfalls

Long or sharply curved trajectories can produce warping/limb-breaking artifacts; overlapping trajectories for adjacent regions often bleed into each other.
