Person A: Let's watch this video now kids. [plays the video]
[the dog in the video starts to bark at someone]
Person A: What is the dog doing?
A child: He's barking at someone.
- In this exchange the participants are kind of treating the paused frame [this barking] as a live event / something happening now and that's why they speak of it with the continuous -- is my understanding right?
On the other hand, when if the participants focused on a broader part of the video, on some sequence of actions, then they would use present simple: the dog gets irritated by a stranger then starts to bark etc. Right?
- Could person A ask at the paused frame about a signle action like: What does the dog do now?
And a kid would reply: it barks
From what I wrote above this sounds wrong to me.
