Making a great submission video

We know you’re focused on preparing your submission, but don't forget about your video. It will help the judges to review your project, and after the challenge has wrapped up, it will be shared in local Developer Circles. Please keep it to around 2 minutes long!

A good video tells the story behind your submission, providing a clear and concise explanation of what your app is and does. Here are some best practices:

  • Establish your elevator pitch. In the first few seconds of your video, explain how your app helps achieve the SDG goals. You can get into the details of how it works later on in the video, but treat the opening seconds of your video as you would a movie trailer or TV ad: pique your audience’s interest.
  • Show, don't tell. Demonstrate your app’s functionality and features through screencasts. Explaining what it does and how it works helps judges and voters understand and appreciate your product design.
  • Keep it simple. Per the official rules, your video shouldn't be much longer than two minutes. As Cicero told us, "Brevity is a great charm of eloquence."
  • Don't wait until the last minute to upload your video. Due to file size, format, and your Internet connection, uploading a video to YouTube, Vimeo, or Youku could take anywhere from a few minutes to several hours.
  • Get organized. Write out a script of what you’ll say and demonstrate in your video and rehearse it before recording.


If you have any questions about the hackathon, please post on the discussion forum.
