Used Microsoft Hyperlapse Mobile app on the Lumia 1520 (available on Android, W10M & WP 8.1) to enhance an existing video that was 443 MB and rather shaky. The Hyperlapse version has removed the shake & shrunk the video down to 80 MB, now uploaded to Flickr. See https://flic.kr/p/XmNbQN. I overcompensated with the exposure on the day, however.
