This is a good question. You are on the right track.
Here are a few points you need to keep in mind.
First, you have two conjugations of verbs here. Do, dare, dedi, datum (1st conjugation). Video, videre, vidi, visum (2nd conjugation).
Second, when you create the imperative in the 1st conjugation, the ending is a or ate. When you create the imperative in the 2nd conjugation, the ending is e or ete. More specifically, the a and e are the singular imperative, and the ate and ete are the plural imperative.
So, da = give! You are commanding one person. Date = give! You are commanding many people.
Vide = See! You are commanding one person. Videte = See! You are commanding many people. So, both vide and videte are translated See! The first is singular and second is plural.
The problem is in the English, we do not have a way to differentiate the singular imperative and plural imperative.
