Kronos is a third party time remapping plugin for After Effects, that means it helps you to create super slow motion effects even if your footage is shot at standard 25fps or 30fps. It is similar to the Time Warp plugin which is pre installed in After Effects.
To create slow motion, new frames have to be generated. Just repeating frames results in very poor quality output with blurring and stuttering, and motion vector techniques have traditionally been very slow to render.
Kronos produces far superior results by creating brand new frames using optical flow/motion estimation, and at incredibly high speed thanks to its ability to utilize your Nvidia GPU for offloading processing.
Kronos uses clever maths to look at every pixel on each frame, tracking where it moves to on the next. By comparing the two, it estimates what would appear in-between, allowing the creation of additional frames and a super smooth slow-motion result. This knowledge also allows Kronos to add high motion blur to your clip based on the movement of objects within it. Inside Kronos we have isolated this ability as a separate plug-in, MotionBlur. Both Kronos and MotionBlur operate in full range float, to preserve your super-white and super-black pixel information.
Check out what you can achieve with this plugin in the video below. The left side of the video shows us the slow motion effect created with Kronos whereas the right side is the result of standard Time Warp plugin.
