Doubt in project submission

Is it necessary to submit the video of the project along with the project itself or can we place it separately.

It is optional for displaying a video. But it would be helpful to gain extra marks for the final project. You have to attach it to the project.

So when I tried to submit my video using google drive link,it showed its incorrect video url.
What should I do?
