There's an easy way to save an embedded HTML5 video, such as a YouTube video currently opened in Safari. You have to create a special bookmark in Safari first. Later, when you have a
webpage with an embedded HTML5 video opened in Safari, you can select this special bookmark, and the video file will be automatically downloaded to GoodReader. To create this special bookmark, open GoodReader's settings, General
section, and tap the button called bookmark for video. Then go to Safari and create a new bookmark. Bookmarking absolutely any page will do at this initial point. Name this bookmark, for example, Save video to GoodReader. Then
press the bookmark button, and then Edit. Select this new bookmark. Now Safari will let you modify the address of this bookmark. Delete the old address and paste the text from the pasteboard (GoodReader has prepared this unique text for
you in the pasteboard). Save the modified bookmark address. The new bookmark is ready to be used in Safari for saving YouTube videos.
