About

Director of Facebook’s Video Processing Team, part of the Video Infra org, and responsible for Facebook video products like Instagram, Live, Reels, and Watch. My current passion is reducing the complexity, cost and power requirements of video processing; a top consumer of power in global data centers. The work we are doing will change the way the world encodes video. --- Netflix In nearly 12 years at Netflix, I was a key contributor to our device streaming technology as we grew our Streaming business from an IE plugin to many millions of devices. See the linked video "A Brief History of Netflix Streaming" for a nerd dive into Netflix streaming. We worked to optimize our audio and video encoding systems to meet global scale. This included asset inspection, cloud-based parallel encoding, and next-generation packaging and DRM tools. Video quality was also a major focus of our team, and we worked to define new models for video quality analysis. Having built a foundation of scalable technologies including parallel inspections and encodes, internal EC2 spot market, and an exceptional subjective video quality metric (VMAF), we are then began running large-scale experiments focused on leveraging our cloud capacity to produce the highest possible video quality at the lowest possible bitrates. All part of our "Aim-Low" initiative. The result of this effort is a good streaming experience at video bitrates as low as 100Kbps. For more details, see the encoding video and tech blog links below. We also invested in new and exciting technologies such as Dolby Vision HDR, and interactive content. As always, we design for scale at the start. Because of this work, Netflix has been able to deploy the largest library of HDR content on the planet.

  • I am currently leading the teams that own the Facebook Video Processing platform, which carries a significant amount of Facebook's Live and VOD traffic. In the video encoding world, it is a general rule of thumb that you can reduce any two of bitrate, computational complexity, and distortion. To meet the demands of modern video at Facebook scale, we must simultaneously solve all three. This is a really big problem. Exactly the sort of challenge that we love.
