The edit will work best if you "cut on the action." That is, cut during the movement, not before or after.

Cutting on the action is almost always preferable to cutting before or after. Of course, not every sequence has action, but if you have the opportunity to cut on the action, it creates a more seamless edit. Watch both.

 

The top example is OK, but it cuts after the action. That is, after she sets down the pink lab sample. Better to cut in the middle of her movement. That’s what happens in the lower version. Note how the edit is more seamless, more invisible in the lower version.
