A method (10, 30) for identifying stationary regions in frames of a video sequence, the method comprising: receiving an encoded version of the video sequence, wherein the encoded version of the video sequence includes an intra-coded frame followed by a plurality of inter-coded frames (201, 202, 203, 204); reading coding-mode information in the inter-coded frames of the encoded version of the video sequence, wherein the coding-mode information is indicative of blocks of pixels in the inter-coded frames being skip-coded, wherein a skip-coded block of pixels (210, 212, 406) in a frame of the video sequence is a block of pixels (210, 212, 406) encoded as a copy of a spatially coinciding block of pixels in a preceding frame of the video sequence; finding, using the read coding-mode information, one or more blocks of pixels (210, 212, 406) that each was skip-coded in a respective plurality of consecutive frames in the encoded version of the video sequence; maintaining one or more timers (220, 222, 408), each timer (220, 222, 408) corresponding to a block of pixels and indicating in how many consecutive frames before and including a present inter-coded frame said block of pixels (210, 212) was skip-coded; identifying each found block of pixels (210, 212, 406) as a stationary region in the respective plurality of consecutive frames; and modifying video data of the frames of the video sequence to make video data in the identified stationary regions less salient than video data in other regions, wherein the video data in the identified stationary regions is made less salient by reducing its luminance, chrominance and/or opacity, wherein a level of saliency of a block of pixels in a stationary region in a frame of the video sequence is set depending on the timer which is maintained for that block of pixels, wherein the level of saliency decreases with increasing value of the timer. receiving an encoded version of the video sequence, wherein the encoded version of the video sequence includes an intra-coded frame followed by a plurality of inter-coded frames (201, 202, 203, 204); reading coding-mode information in the inter-coded frames of the encoded version of the video sequence, wherein the coding-mode information is indicative of blocks of pixels in the inter-coded frames being skip-coded, wherein a skip-coded block of pixels (210, 212, 406) in a frame of the video sequence is a block of pixels (210, 212, 406) encoded as a copy of a spatially coinciding block of pixels in a preceding frame of the video sequence; finding, using the read coding-mode information, one or more blocks of pixels (210, 212, 406) that each was skip-coded in a respective plurality of consecutive frames in the encoded version of the video sequence; maintaining one or more timers (220, 222, 408), each timer (220, 222, 408) corresponding to a block of pixels and indicating in how many consecutive frames before and including a present inter-coded frame said block of pixels (210, 212) was skip-coded; identifying each found block of pixels (210, 212, 406) as a stationary region in the respective plurality of consecutive frames; and modifying video data of the frames of the video sequence to make video data in the identified stationary regions less salient than video data in other regions, wherein the video data in the identified stationary regions is made less salient by reducing its luminance, chrominance and/or opacity, wherein a level of saliency of a block of pixels in a stationary region in a frame of the video sequence is set depending on the timer which is maintained for that block of pixels, wherein the level of saliency decreases with increasing value of the timer.
