FrameTrail
FrameTrail
FrameTrail is an open source software that lets you experience, manage and edit interactive video directly in your web browser. It enables you to hyperlink filmic contents, include additional multimedia documents (e.g. text overlays, images or interactive maps) and to add supplementing materials (annotations) at specific points. Use any video file or even an empty video with a defined length as a basis for synchronization. Place documents on top of the video (e.g. text, images, web pages or interactive maps) and decide how and when they should be displayed. Create non-linear networks of video fragments (Hypervideos) which can be freely navigated by the user. Add supplementing materials at certain points of time and compare those with the annotation timelines of other users. In order to allow everyone to freely install, adjust and extend FrameTrail, we decided to use intentionally simple technology and self-contained formats. Everything is filebased (no database). -
