I was searching for some free assets one can use in videos and stumbled upon Shutterstock’s ones (for example https://www.shutterstock.com/blog/191-free-video-design-assets). In the videos explaining how to use these they used blend modes. Of course, the beginner I am, I had no clue how to do this in Shotcut - I never heard of blend modes before. Fortunately there were some topics about it and I was able to blend some clips with a text clip (https://streamable.com/zwdvm):

Because there are no videos in this category, I decided to create a topic; even though my video is really simple.
If you have videos with (more difficult) examples, you can post them, I would appreciate that.
Edit: For a screenshot where to find the blend mode: Timeline Track:V1 Blend mode? Usage?
