    Video

    You are required to provide a youTube video of your app executing. You must demonstrate the features of your program in the video.

    The video can be recorded using a device, such as a smart phone, if the video quality is sufficient for the graders to see the program execute. Alternatively, screen capture software such as screencastify , which is a free browser plug-in that captures your screen and audio and saves it as a video. A tutorial on screencastify is at https://www.youtube.com/watch?v=2tlE2wwVXg8 [2:54].

    Videos can be edited using YouTube's video editor; here are some resources on that:

    The video must be 45seconds to 60seconds (no shorter or longer). You must narrate your video describing its features. You may narrate with your voice over the video, or you may narrate by providing a written description of the video in your answer document. Start the video with a clear shot of your initials on the app user interface to show it is your app. Place in your answer document the full clickable URL of the video on youTube. . Make sure that the youTube permission is set to "Public" or "Unlisted" - if it is "Private" we can't grade it and you will receive no credit.
