1. A method comprising:
determining, by a computing device, a filter to determine an up-sampled value for a first layer for a video, wherein the filter has a set of coefficient values of [−1, 3, −9, 47, 31, −10, 4, −1] assigned to the filter;
determining, by the computing device, the up-sampled value by applying the set of coefficient values of [−1, 3, −9, 47, 31, −10, 4, −1] to the plurality of sample values;
outputting, by the computing device, the up-sampled value for use in coding a second layer of a higher resolution than the first layer,
wherein the filter comprises a first filter, the set of coefficient values comprise a first set of coefficient values, and the up-sampled value comprises a first up-sampled value, the method further comprising:
determining a second filter, wherein the second filter has a second set of coefficient values of [−1, 4, −10, 31, 47, −9, 3, −1] assigned for the second filter;
determining a second up-sampled value by applying the second set of coefficient values of [−1, 4, −10, 31, 47, −9, 3, −1] to the plurality of sample values; and
outputting the second up-sampled value for use in coding the second layer of the higher resolution than the first layer.
