1. We drag the footage from the material library onto the video track, and then we can see "setting the Ripple Mode" in the menu above the video track.
2. The above illustration shows that shading mode is turned on. In this mode, if we remove the first footage from the timeline, the second picture occupies the position of the first picture. However, if there is a picture in the previous video track, the image here will not change the position, so it can only achieve the picture changes on a single track.
3, when we turn off the shading mode, delete the first picture, the second picture position is still unchanged oh (Turn off shading mode, as long as the figure above the "Shading mode settings" is good).
4. What if we want to change the position of all the material on the track? It's really simple, we just need to get to the sync machine OK.
