GridWarp

GridWarp remaps pixels within editable grid cells. One region can remain nearly stationary while another stretches, bends or conforms to a surface. Use a separate Transform when the task only requires moving the entire rectangular image.

Source defines the original grid positions and Destination defines the target positions. Prepare X/Y Grid Size and Source shape first, copy Source to Destination once, then edit Destination. Changing X/Y or using Set Mesh To Entire Image resets the grid; copying over an edited state also overwrites its shape.

Selected affects selected vertices. Region uses vertices inside its area at drag start; Magnetic also includes newly encountered vertices during the drag. Magnet Distance sets the radius and Magnet Strength controls influence within that area. Adjusting them separately helps avoid abrupt creases.

X/Y Grid Size sets the primary editable divisions. Subdivisions refines evaluation between existing vertices without creating extra handles. Choose density before editing and judge intermediate surface quality separately from editing convenience.

Edit Grid works with vertices; Edit Rect exposes the rectangle and Center. In Edit Line, draw a spline around an object to construct the grid; Point Tolerance, Oversize Amount, Snap Distance and separate shaping-spline animation are available there. This is a shape-construction workflow, not a mode for moving one line of an existing grid.

The mesh remains static until animation is enabled through the mesh animation context menu. Animation stores whole-grid states, so inspect intermediate frames as well as key poses: cells may cross during interpolation. For titles, morphs and flexible transitions, distribute deformation over neighboring vertices.

Render Method selects an image, wireframe or colored visualization. Compare Anti-aliasing and Filter Type for final image output; Wire Frame has separate line-width and smoothing controls. Black Background determines pixels outside the grid, while Object ID/Material ID belong to auxiliary channels of the output image.

Pages 3022–3027 of the Resolve 21 manual document the main image input and post-processing Effect Mask. The mask blends the warped result with the source and needs a seam check at large displacements. Six original captures preserve normal Controls/Render and menus; the reference identifies conditional Edit Line/Wire Frame controls separately.
