1. A method for encoding a video stream, the method comprising:
acquiring pixel data of the video stream;
extracting a crop corresponding to a region of interest from the pixel data, the crop having the first resolution;
down-scaling the pixel data into a down-scaled video stream having a second resolution lower than the first resolution;
processing the down-scaled video stream through one or more video processing operations, the one or more video processing operations comprises at least one of a noise reduction function, a rotation function, an image sensor correction function, an image scaling function, a gamma correction function, an image enhancement function, a color space conversion function and a chroma subsampling function;
processing the crop through the one or more video processing operations;
up-scaling the processed down-scaled video stream into an up-scaled video stream having the first resolution;
merging the processed crop and the up-scaled video stream into a merged video stream; and
encoding the merged video stream.
