1. A method comprising:
- encoding, by a video encoder and based on a first quantization factor (QP), one or more first groups of image blocks of a first video frame;
estimating, by a processing device the size of an image slice comprising a first plurality of further groups of image blocks to be encoded; and
determining, based on the estimated size of the image slice, a second quantization factor (QP) to be applied to one or more of the further groups of the first plurality of further groups.
