Futatabi is a free software solution for doing instant replay, e.g. for sports production. It supports multiple cameras, high-quality realtime slow motion on the GPU through optical flow, and seamless integration with Nageru, my live video mixer. We'll talk a bit about how interpolation through optical flow works, challenges in transporting the streams back and forth, and demonstrate a real-world sports production done last year using Nageru and Futatabi.

Nageru is an M/E (mixer/effects) video mixer capable of high-quality output on modest hardware. We'll go through the fundamental goals of the project, what we can learn from the outside world, performance challenges in mixing 720p60 video on an ultraportable laptop, and how all of this translates into a design and implementation that differs significantly from existing choices in the free software world.

Movit (the “Modern VIdeo Toolkit”) is a high-performance, high-quality, open-source library for video filters, running on the GPU. Come see what the future holds when open-source video editing steps into 2014!

Movit contains everything you need and expect for basic video filtering requirements (scale, blur, sharpen, mix, overlay, simple color grading, and others). Movit is supported in MLT, has full support in Shotcut and is on track for Kdenlive support.

In this talk, I'll talk a bit about:

• What does Movit do, and what doesn't it do?
• What do we mean by “high-performance”? Why the GPU?
• What do we mean by “high-quality”? How hard can a blend be anyway?
• What goes on behind the scenes in Movit's filter graph?
• How do you embed Movit in your own application?

There will also be a demo of Movit in action, and of course Q&A if time permits.
