Facebook’s Engineering Wizardry Makes Even VR Videos Load Fast

SVE lets Facebook cut videos into little chunks, cutting the delay from upload to viewing by 10X. And to ensure the next generation of 360 and virtual reality videos load fast too, it’s invented and open sourced new geometric encoding formats.

By mapping a spherical video into cube with Facebook’s specs, 360 videos drop in size by 25%. And with its pyramid design, 360 videos get 80% smaller. That means even when a video lets you look in any direction, you won’t have to sit there buffering first. Facebook revealed this new tech at its Video @Scale conference, an unabashed attempt to recruit top video…
