1. A method for computing a plurality of bit budgets for a plurality of different frame types in a current group of pictures (GOP), where said current GOP comprises at least one of:

  • an intra coding frame and at least one inter coding frame, comprising;

    determining a complexity measure for said intra coding frame and a complexity measure for said at least one inter coding frame;

    calculating a bit budget for said intra coding frame and at least one bit budget for said at least one inter coding frame;

    obtaining an average quantization level (QL) over inter coding frames in a previous group of pictures (GOP);

    determining whether said average quantization level has exceeded a predefined level; and

    allocating an additional amount of bits to said bit budget for said intra coding frame if said predefined level has been exceeded.
