A method of encoding digital video data corresponding to a sequence of input video frames is disclosed. The input video frames are encoded into a sequence of output video frames. The method comprises encoding a first input video frame in a first encoder instance using intra-frame encoding to produce a first intra-frame, decoding the first intra-frame to produce a first decoded frame, encoding the first decoded frame in a second encoder instance to produce a first output video frame. A digital video encoding system is also disclosed, as well as a camera comprising such a system, and a computer program product for performing the method.
