Claim One:
1. A computer-implemented method for video coding, comprising: receiving a prediction error data partition corresponding to input video for transform coding; partitioning the prediction error data partition into a plurality of coding partitions of the prediction error data partition including a first subset of the plurality of coding partitions and a second subset of the plurality of coding partitions, wherein the first subset of the plurality of coding partitions comprises one or more coding partitions having a height of less than or equal to 16 pixels and a width of less than or equal to 16 pixels and the second subset of the plurality of coding partitions comprises one or more coding partitions having a height of greater than or equal to 16 pixels and a width greater than or equal to 16 pixels; performing a content adaptive parametric transform on a first coding partition of the first subset of the plurality of coding partitions in response to the first coding partition of the first subset having a height of less than or equal to 16 pixels and a width of less than or equal to 16 pixels, wherein the content adaptive parametric transform comprises content dependent basis functions determined based on decoded video data neighboring the first coding partition; performing a fixed transform on a second coding partition of the second subset of the plurality of coding partitions in response to the second coding partition of the second subset having a height of greater than or equal to 16 pixels and a width greater than or equal to 16 pixels, wherein the fixed transform comprises fixed basis functions; encoding a bitstream with quantized transform coefficients corresponding to the content adaptive transformed first subset of coding partitions and the fixed transformed second subset of coding partitions; and transmitting the encoded bitstream.
