There is provided methods, apparatuses and computer program products for video coding and decoding. A first part of a first coded video representation is decoded, and information on decoding a second coded video representation is received and parsed. The coded second representation differs from the first coded video representation in chroma format, sample bit depth, color gamut and/or spatial resolution, and the information indicates if the second coded video representation may be decoded using processed decoded pictures of the first coded video representation as reference pictures. If the information indicates that the second coded video representation may be decoded using processed decoded pictures of the first coded video representation as a prediction reference, decoded picture(s) of the first part is/are processed into processed decoded picture(s) by resampling and/or sample value scaling; and decoding a second part of a second video representation using said processed decoded picture(s) as reference pictures.
