No problem. If you think it's too much work, feel free to contract more freelancers for the same project, I can and am used to work with a team.
Also, if the video is less than 60 seconds, but it will become longer than 60 seconds after adding you 6 seconds clip, in which category it will enter? Intro in the front or at the end?
Call me on chat if I can work in this project, so I can start right now to download the videos. Thanks.
