Abstract: In a computing device for simulating the application of cosmetic effects, a user interface with a plurality of cosmetic templates is displayed to a user, where each cosmetic template comprises a predefined sequence for applying cosmetic effects. A selection of one of the cosmetic templates is obtained from the user, and a digital representation of the user is captured. The computing device tracks facial features of the user in the digital representation of the user and generates a virtual mirror for the user to view. The virtual mirror displays progressive application of each of the sequence of cosmetic effects of the selected cosmetic template to corresponding facial features in the digital representation. A digital representation of the simulated application of all of the sequence of cosmetic effects is then stored.

If necessary, the target key frame is converted to a first frame type. Only the target frame header, the target key frame, and video bitstream that follows the converted target key frame is sent to the client device, where the original frame referencing encoded in the video bitstream is utilized.
