By combining a canvas rendering strategy on the client side, with ffmpeg on the backend, they were able to build a video editing experience in a matter of weeks that supports near pixel-perfect previews that can be edited in real time, and highly optimised mp4 output for the fully rendered videos.
In this talk, Forbes will take you through their approach, and why they arrived at the method they chose. You'll see some of the techniques that were required to scale their canvas solution, both managing the growing complexity, and keeping a lid on their memory usage.
This talk will be especially useful to anyone considering building high-performance graphics for the browser, but it will also give any developer some new ideas about how to approach technical challenges.
