You have shot the video and now kit's time to have a look at the footage, especially the individual frame starts and ends.
Do they look good, or are there parts at the beginning or end to remove?
It is not suggested that you edit within a frame, as this will often cause 'screen jumps'.
Basically it requires placing the cursor at the point to be removed and selecting, then deleting.
Transitions.
You may need to include a transition or two, if really necessary. But do not over do it.
A transition may open the video and end it and end it. But that's all you should have.
Title
At the start of the video a title is always good. This could also include the credits, or you can save them to the end.
