Posting on Instagram is tricky because they don't allow direct posting from a computer, and smartphones also have trouble downloading video files from mobile browsers.

To post your video on Instagram, you'll have to  download the video file from Lumen5, and then deliver the file to your mobile device through a service such as Dropbox or Google Drive.

Here are the steps required to post your video onto Instagram:

1. Download the video file from Lumen5 onto your computer
2. Upload the video file to Dropbox/Drive from your computer
3. Download the video file from the Dropbox/Drive mobile app onto your phone
4. Post the video to Instagram from your mobile device
