A video editing tool developed by Microsoft, designed to make video creation easy and accessible for everyone.
Hello
You can stack multiple timelines, and then put the pictures on the same spots.
For example: drag the second photo onto the timeline above or below the first photo, not beside it. Add any additional photos on more rows above or below them.
Select each photo in the preview window, then: Drag its corners to resize it. Drag the photo to position it. Use Crop, Fit, or Fill from the floating toolbar if necessary.
See screenshot below for example.
