This is a proper delivery for a video that is meant to animate in, hold on a frame, and then animate out.
You must tell us the frame number where the hold frame starts. In this case it is "frame 60".
On a cue we can trigger the animation out portion. In this case that is "frame 61" through the end of the clip.
Delivering two or three files slows down programming, increases the chance of a programming error, and in same cases is less performant.
