A clip is a piece of media that is in the Timeline. It is represented by a gray box in the timeline area.
Here is a clip called Screen Recording
in the Timeline,
starting at time 0 and ending around 7.5 seconds into the
presentation:
The position of a clip in the timeline defines when the clip starts playing and when it stops playing. The left side of the clip defines when the clip starts playing. The right side of the clip defines when the clip stops playing.
If you want the clip to start playing at 1 second in the presentation, click on the clip and move it so that the left side is at 1s (one second).
If you want to have more than one clip playing at the same time, then you can add another clip.
Below, we have dragged a PNG image called logo.png
from the Document Media tab of Properties area to the timeline, just
above the Screen Recording
clip.
Because the logo.png
clip is above the Screen
Recording
clip, it appears to be in front of the Screen
Recording
clip:
