Abstract: There is provided a method and an encoder for inter-encoding an image frame in a sequence of image frames. The method comprises obtaining a compression level for each pixel block of the image frame, inter-encoding the image frame in a first encoding pass using the obtained compression level and identifying pixel blocks in the image frame that were intra-coded in the first encoding pass and for which the obtained compression level exceeds a compression level threshold. The method further comprises lowering the compression level for the identified pixel blocks, and inter-encoding the image frame in a second encoding pass using the lowered compression level for the identified pixel blocks and the obtained compression level for each remaining pixel block.
