Hi @Gunther_Dorn,
As it happens a year or two ago I made lots of short mp4 files, each one featuring a revealing box (square or rectangle) of different sizes. I made them using HTML/CSS and @elusien’s webvfx, for use in my tutorial videos.
Anyway your post has prompted me to upload the whole lot to my Google Drive:

Feel free to download , choose the right size and use in your video.
Place on a track higher than your text track. To remove the black background, either apply a chromaKey filter or a Blend Mode filter set to “add”.
