Imported keyframes are placed OUTSIDE of a reduced clip.
If i reduce a clip (for example removing first seconds) and i use Automask to take keyframes.. when i import the generated keyframes to an effect (for example position and zoom) the keyframes not fill the entire clip.. but a part of keyframes are placed outside of the clip (from where the full size clip start..)
looking at video the last seconds of clip has not keyframes on it.
