<p>There are provided methods and apparatus for video encoding and decoding using region-based flipping. An encoding apparatus includes a video encoder (400) for encoding image regions of a picture into a resultant bitstream, wherein at least one of the image regions is flipped (402) before encoding. A decoding apparatus includes a video decoder (500) for decoding image regions from a bitstream, wherein at least one of the image regions is flipped (577) after decoding.</p>
