How to make time-lapse photography with sound shadow x9?

There are two ways to do this. The first kind of material is video material. You just need to find the speed item in the editor and adjust it to the fast or slow speed you need. The second material is the photo continuous shooting material. After dragging all the materials into the movie box, hold down sihft and select all the photos with the cursor, or right-click the position below to select all the media.

Then left-click in the position below.

After the above selection is completed, right-click all the photo materials to set the operable photo time interval.

Just select all the photos and click the button on the right. This button is dark and cannot be operated.

I also searched the Internet for a long time, but I couldn't find the answer. Later, I asked a master to understand.
