The video downloader I use is the
Video Downloader app on the iPad;
https://itunes.apple.com/gb/app/vide...661041542?mt=8
The app downloads from any/most sites that have video and saves it to the device.
The
£2.99 full version allows you to save the vid to your 'camera roll' for sharing.
Very simple to use, simply type/paste url into the apps browser and when the vid starts playing, a 'download video' button appears which initiates the download to your device.
