What is the meaning of "I saw you WALK in the street" when using infinitive form?

Question

What is the meaning of "I saw you walk in the street" when using bare infinitive form (walk)?

If I want to say to someone that I saw him (for example while I sit in the bus) in the street, then I would say

"Jon, I saw you while you were walking in Manhattan street"

But I have other options that I'm not sure about their meaning nor correctness:

• "Jon, I saw you walking in the street of the center"

• Jon, I saw you walk in the street of the center"

Answer 1

What is the meaning of "I saw you walk in the street" when using bare infinitive form (walk)?

It means that you saw the entire action (walking). That is, looking at them at their first point of the walk until the last.

"Jon, I saw you walking in the street of the center"

This means that, you saw only some parts of his walking in the street not the entire walk.

PS: Use on the bus not in the bus for your sentence.
