footage vs instalment

Please, what`s the difference between footage and instalment. To me they are similar. What do you think about? Thanks.

I can’t see how they could be related. Can you give us an example in which you think they are similar?

Excuse-me Mister Micawber, I thought there was a relation between “part of a film showing a particular event(footage) and one part of a story that is shown or published as a series (instalment)”, for example. Certainly I have not expressed correctly. I thank you for your patience with learner like me. Regards.

No, no relation.
