In the context of analyzing say parent-child interactions, what is a direct observation vs indirect?

Thanks anyone! Google isn't helping!

Oh here we go...
"The most common method of indirect observation involves interviewing
adults who know the target children well enough to provide meaningful information."

Whereas I suppose direct is observing a video or the actual child.

Thought I'd just follow up with the answer in since I'd asked the question!

Cheers
