A method of decoding video, comprising: receiving an encoded bit stream representing frames of video, each of the frames comprising blocks of pixels; for a current block to be decoded, obtaining a vanishing point from the encoded bit stream and calculating pixel values of the current block to be decoded by performing intra-prediction based on a prediction line originating in the vanishing point; and providing decoded video based on the calculated pixel values. A method of encoding video, an encoder, and a decoder are also disclosed.
