Does anyone know how I can create a montage on the PC and with which program and it should be very easy to use.
Should work with every editing program. Just needs a little practice.
Microsoft PHOTOS app for Windows 10 PC and mobile device
A simple video editor with some predefined effects and filters, even a small selection for background music is included. Rotate picture, change speed, insert title. Rather even easier than the MovieMaker.
At: Microsoft Store
ShotCut is an open source video editing program. All common formats for video, photos and audio can be edited on multiple tracks. No markers. Transform and lots of filters and effects. Partly with keyframes! Stabilizer, rudimentary titler tool. Audio visualization. Export as a video file to a directory e.g. USB stick. Does not include a video DVD burning tool. Language selectable, but without help function and manual in German.

Okay, thanks for the suggestions.
But how can I record clips and add them to the program?
Photo or video camera, iPhone, from the screen with Captura or something like that
