How to create a default thumbnail by merging images with videos?


I have 3 parts (vdo clips) wanted to merge them together, then insert an image at the first part in time line, and set the duration for 1 second,

Please help about merging images with video clips, ad setting it as a thumbnai,

You can find tutorials at Basically, you just need to adjust their timing values on Timeline then export to a final video.

Regarding thumbnail setting, that should be done on YouTube, there is nothing to do with ActivePresenter in this case.
