Video animation

The peculiarity of video animation is that you also need to configure playback animation. Otherwise the video will start playing immediately but will appear later (delay + time for the appearance animation).
That is, if you need to configure the video's appearance and disappearance, then in addition to animating the object's properties you must add two video animations (play/pause).
The checkbox next to "Value" will turn the video on; an unchecked box will turn it off.
