Mview

The mview command can store and delete movie keyframes.

Keyframes store a view (camera or object position) and optionally the object state and/or a scene. Between keyframes, PyMOL will interpolate views and states, allowing for smooth animations.

Before using mview, the movie timeline has to be set up with mset.

Usage

mview [ action [, first [, last [, power [, bias
    [, simple [, linear [, object [, wrap [, hand
    [, window [, cycles [, scene [, cut [, quiet
    [, auto [, state [, freeze ]]]]]]]]]]]]]]]]]]

Arguments

• action = str: one of store, clear, reset, purge, interpolate, uninterpolate, reinterpolate, toggle, toggle_interp, smooth {default: store}
• first = int: frame number or 0 for current frame {default: 0}
• power = float: slow down animation at keyframe (0.0) or not (1.0) {default: 0.0}
• object = str: name of object for object keyframes, or empty for global (camera) keyframes {default: }
• scene = str: name of scene to store scene with key frame {default: }
• cut = float 0.0-1.0: scene switch moment (0.0: beginning of transition, 1.0: end of transition) {default: 0.5}
• auto = -1/0/1: if freeze=0, then auto reinterpolate after store, clear, or toggle {default: -1 = use movie_auto_interpolate}
• state = int: if > 0, then store object state {default: 0}
• freeze = 0/1: never auto reinterpolate {default: 0}
