Best method for splitting an interactive video into sections within the course presentation

What is the best way to add an interactive video which is divided into sections?

I intend to use the course presentation activity to add notes between different sections of an interactive video. 
Should I use the same interactive video, with different start times for the different sections. Or, should I split the original video file into different sections?

I'm wondering if the first method downloads the video just once or slows things down by downloading loading the entire video multiple times, and if the second method avoids downloading the same content multiple times but might instead slow things down with multiple external calls?

I'll be experimenting for myself but thought I'd ask here in case others have an insight.

Every media file is stored and loaded separately. They are not shared across different instances of interactive videos. Splitting the video into sections is the way to go.
