Start a new project by tapping the + symbol in the top right corner. The second line of the timeline on the bottom of the screen is where your video will go. The third line is where the picture or video you want in the background will go.
Tap the plus sign on the middle line and choose video. Then choose all videos and find the video you want. Tap the video you want, then tap Use. If you need to crop the sides of the picture you can choose the crop tool.
Drag the sides in to crop the picture. Then tap done. Make sure that the red starting line is lined up with the beginning of your video so you can start to add background pictures/video. Tap the plus sign on the third line in your timeline and choose image (or video if you are putting in a background video). Add your picture by choosing the camera roll and selecting the picture. You must have previously saved the picture to your camera roll.
You can move around the background picture by selecting it in the timeline. It is selected when the red box is around it. Then in the preview space you can move the picture or make it bigger or smaller. You can do the same with the video. You can make your picture longer in the timeline by touching the red square at the end of the picture and dragging it farther in the timeline. To add more pictures or videos to your project, line up the vertical red line in the timeline to the spot you want to add the next picture. It is helpful to make note of the time in the video that you want the next picture to come in at. Then choose the plus sign and add your next picture. Tap Save when your video is complete. It will start exporting your video.
Then you can save it to your camera roll. ______________________________________________________________________
