Abstract

This disclosure relates to methods 900, software, devices and systems for encoding an image frame in a video stream, such that a decoded version of the encoded image frame is provided with a first masked region. A block-aligned mask is applied S906 to the image frame being encoded and a pre-generated encoded image frame is used to transform the block-aligned masked region during decoding. The pre-generated encoded image frame contains motion vectors but no residual data, allowing for efficient transformation of a block-aligned masked region into the first masked region having an edge that cuts through coding blocks.
