Abstract
A method and an apparatus for forming a video stream based on images of a scene captured by a camera. The method comprises: encoding image frames based on images captured by the camera, forming an encoded portion; determining a length of motion for a sample image frame, the length of motion being indicative of the amount of relative motion between the camera and the scene in the sample image frame relative a temporally preceding image frame; setting a motion length threshold based on a motion vector search range of the encoder; comparing the determined length of motion with the set motion length threshold; based on the outcome of the comparison, adjusting a chosen temporal frame distance of at least an adjustment portion (P) of the video stream, wherein the adjustment portion is comprised in the encoded portion or in a temporally later encoded portion.
