video editing

You are talking about transitions. Beginners can use basic video editors like VN Video Editor and CapCut to learn the basics like transitions. Bro, you can find numerous tutorials on this on youtube, linkedln and X.

However, in VN Video Editor (if you like to use):

• Tap the small square icon between the two clips (this is the transition button).
• Choose the “Dissolve” or “Fade” transition from the list.
• Adjust the duration (make it longer for a slow dissolve).

This is very basic stuff and you might find the tutorials available on Linkedin Learning useful.  They're comprehensive and aimed at different levels of experience.  There's a free trial available...  

Hi kevin_4182,

Welcome to the community! Hope the solutions provided by our experts helped. Let us know if you have any questions.

Another way of doing that is to have the two clips on different video tracks and keyframe the opacity of each to get the transition desired.

Make sure to have enough handles:
