Abstract: A video previewing and selection system may allow a user to filter and select video clips based on metadata associated with the video clips, including metadata that defines when certain people are shown in the clips. A set of video sequences may be analyzed to extract existing metadata and present the metadata in a user interface. A user may select various metadata which may be used to filter the selections using logical AND and OR combinations. The user interface may allow a user to view the clips, as well as select clips for further editing by a video editor.

Abstract: A rating mechanism may calculate a rating based on a user's effort and duration of input to an input mechanism. The more effort and time a user exerts, the more extreme the rating. In one embodiment, a mobile telephone may have a wheel, slider, or other mechanism that may change a rating based on how fast and how long a user may activate the input mechanism. In another embodiment, the rating may be based on how furiously an accelerometer within a device is activated, such as by shaking the device repeatedly.
