The topic title might be a bit confusing but couldn't find a better description.

This is the problem:

I have about 20-30 video's/pictures.
I've got a piece of video that needs to be at the start of every video.
Is there a quick way to generate these video's. The ones with the picture must have the pictures displaying for 10-20 seconds. and it takes a lot of time to do this manually.

So is there a way to do this ?

Thank you for your time and attention, Ruler0fAll
