W and H define the encoded frame in pixels. Values use even-number stepping because common video encoding paths handle even dimensions predictably. The swap action exchanges width and height, making a fast landscape-to-portrait or portrait-to-landscape starting point.
Swapping or changing dimensions does not automatically redesign every layer. Review crop, alignment, frame containers, text wrapping, captions, and off-canvas animation after any aspect-ratio change.
The panel displays the draft’s frames per second and formatted duration. Frame rate is a read-only project timing contract in the current interface. Duration is derived from composition state rather than edited as an independent field here.
Changing dimensions changes the coordinate space against which top-level layers align. Existing absolute positions remain numeric values; a former visual center may no longer be centered. Parent-managed layouts remain internally coherent but their top-level frame may still need repositioning or resizing.
Composition dimensions and frame rate flow into playback evaluation and H.264 rendering. Canvas view zoom, browser window size, and panel geometry do not. For a render estimate or downstream delivery requirement, use composition pixels and duration—not the screenshot size of the editor.See frame math, H.264 rendering, and frames.
