A preformed web and a method of producing dunnage units from the preformed web. Two copies of the original codeword are transmitted to the receiver via physically distinct channels to increase the robustness of the telecommunications channel between the transmitter and the receiver and to minimize the elapsed time between when the transmitter transmits the original codeword and when receiver has a final estimate of the original codeword available for output. Free fatty acids are then removed through physical refining, instead of previously employed caustic refining, since the low level of nonhydratable phospholipids does not create undesirable flavors during the physical refining process. A temporal motion vector for a block of the second frame is calculated as a combination of respective motion vectors of blocks overlapping the block of the second frame if at least one of the overlapping blocks is an extrapolated block at the extrapolated position. The process includes the use of conventional settlers at the beginning and at the end of the extraction process with at least one reduced-size extraction cell in the middle of the extraction process.
