Creating screensaver video in iMovie (origami, shrinking tiles, etc)

Try creating a slideshow in the Photos app using the Origami theme. Then export the slide show as a movie to your desk top. Create an iMovie project and drag the exported slide show into its time line. Then add your vertical videos in the auxiliary timeline above the slide show video. With each video, overlay it as a Picture in Picture into the slide show. You can use the Keyframe feature of Picture in Picture to make each vertical video move into the slide show from different angles if you want.

Here's an online help menu explanation of how to use Picture in Picture:

Thank you for the kind sentiments. :)

There are several themes in the Photos slideshow feature. Here's a list:

All of them scroll in some fashion. The best way would be to create a slide show and then click through the various themes until you find one that gives you the effect that you want. I kind of like the Vintage theme because it is somewhat unique. Reflections is a nice theme where the photos vacate the screen and are replaced with one or more photos in an arrangement. The Classic theme scrolls one slide after another with no tricks.

I don't recall the ticker tape type scrolling, other than in an iDVD theme.

You can make your own if you want to do a little work. Create an iMovie project. Put in a black background into the time line. Adjust its duration to the duration of your slide show. Then put the slides into the auxiliary time line above the black background. Select the first picture. Make it a Picture in Picture. Adjust its size to full size. Slide it to the left so that maybe a half inch of the slide is showing in the preview screen. Add a keyframe. Advance the time line playhead to the middle of the slide in the timeline. Move the slide in the preview screen to the center of the preview screen. Add a key frame. Advance the timeline to almost the end of the slide. Move the slide to the right so that only about one half inch is showing in the preview screen. Add a key frame. Click on the blue reset button to apply your changes. Repeat this process with each successive slide. You should end up with a slide show where the slides are scrolling by from left to right. Share out the slideshow to your desktop as a movie. Import the movie into your master iMovie project. Then add your vertical videos to the auxiliary timeline on top of the video slide show. With each video, overlay it as a Picture in Picture into the slide show.

It might take a little tinkering.
