SequentialAnimation runs but not ParallelAnimation

[dstudentx]

For some reason when I run SequentialAnimation from animations run but if I change it from SequentialAnimation to ParallelAnimation it does not.
@
SequentialAnimation {
id: playbanner
running: false

NumberAnimation {
target: film_list_background_image
property: "opacity"
to: 1
duration: 2000
}
NumberAnimation {
target: movie_list1
properties: "y"
to: 267
from: -371
easing.type: Easing.OutBounce;duration: 800
}
.....
......
....
}
