Handling video content

The invention relates to creating a combination video, which shows points of interest from a longer input video. Sub-frames, showing points of interest, e.g. objects or people, are selected from frames, and these sub-frames are overlaid on the desired frames. The aim is to be able to display multiple object timelines on a single frame, to increase the efficiency of video editing. The method comprises; receiving video content comprising a plurality of image frames; displaying a single image frame; selecting a sub-frame, comprising a portion of the displayed image frame; superimposing the sub-frame on top of the image frame, along with associated content of the sub-frame, e.g. the same item or area contained within the sub-frame, but displayed on other image frames. The sub-frames may be displayed in a time sequence over a static image, and may be displayed at a different location to that of the selected sub-frame. The sub-frame may be selected by user input, or by software. The image may be displayed on a Head Mounted Display (HMD).
