A video codec provides for encoding and decoding pictures of a video sequence at various coded resolutions, such that pictures can be encoded at lower coded resolutions based on bit rate or other constraints while maintaining a consistent display resolution. The video codec further provide for encoding and decoding pictures of the video sequence at ranges lower than that used for display, and then expanding the range after decoding for display. The video codec applies post-processing operations, such as de-blocking, de-ringing, and color conversion, at the native resolution and range of the decoded video, prior to range expansion and upsampling for display.
