Download or get the Instagram video I saw earlier Device: Samsung Galaxy S3

A person I followed had a cool video they posted on Instagram, but then deleted it later. I was wondering if there was a backup of the video in the temp folder, since I watched it earlier?
The location of the Instagram cache is storage/android/data/com.instagram.android/cache/video 
However, when I look on my device, it seems that the files are not stored in a traditional video format. You should be able to find the video there, if at all though.
