How to Encode Video for the Future Dror Gill, CTO, Beamr Abstract The quality expectations of viewers paired with the ever-increasing shift to over-the-top (OTT) and mobile video consumption, are driving today’s networks to be more congested with video than ever before. To counter this congestion, this paper will cover advanced techniques for applying content-adaptive encoding and optimization methods to video workflows while lowering the bitrate of encoded video without compromising quality.

The standard method of encoding video for delivery over the Internet utilizes a pre-set group of resolutions The rate control algorithm adjusts encoder parameters and bitrates known as adaptive bitrate (ABR) sets.
