KPEdit is a free animation editor used to create skeletal animations. It is made as an alternative to motion captures. Using it you can create skeletal animations for 3D characters and then, export the animations in *.json file format or, render a stick-man animation using the export option.

It is a handy tool for animators, as motion capture systems are expensive. Using it you can manually add the points, create a stick man type skeletal, and animate it frame by frame. You can create an animation from a scratch, or you can import a video into the freeware and then draw on it and use it as a reference for the animation.

Here is a simple animation I created using this animation creator (note: output below is from a Video to gif software, to convert recorded animation video to gif).

KPEdit Animation

The freeware consists of various handy tools and options, which can help you throughout the animation creating process. For example: you can can add multiple points and frames, move points position frame by frame, select-delete points, duplicate frame, delete frame, import video (to be used as reference), change frame interval, play, pause, rewind animation, jump to next/previous frame, rearrange frame, link points, enable previous frame hint(for creating better animation), interpolate (auto-insert multiple frames and points between two point positions and frames), and lot more.

Create, edit, and save skeletal animations using this animation editor:

KPEdit is a good alternative to motion capture systems. Using it you can create some good skeletal animations, that can be later used in 3D animation software. However, the complete process of creating skeletal animation does take time, because you have to create animations part by part. That is, creating animations for hands, legs torso, head  etc. separately and then compiling them together. It’s a long process.

Using the freeware is easy and you can find some video tutorials on how to create animations in KPEdit in it’s website. Like every other animation software, this animation editor is also based on frames and points concept.

You’ll start with adding frames, and then points. There are buttons for these in toolbar. Then, you have to simply change the position of points frame after frame. Good thing is, the freeware lets you view the position  of points in previous frame, making it easy to figure out where to place the points in current frame. To enable it, go to View menu and enable Previous Point Hint option.

The interface is basically divided in 3 main panes: Video playback and reference pane, key point preview pane, and frame list pane. You can draw on both: video playback and key point preview pane.

To make use of a video as a reference for the animation, simply import desired video (click Open video button in far left side of interface), add point, play the video, and draw on top of it by continuous clicks. To help you get a proper control over animation drawing, you can slow down the playback speed. Simply enter a suitable playback speed in Frame interval text box and press enter. The freeware automatically creates frames as the video gets played and adds the points you drew, frame after frame.

Finally, simply connect the points (click on Manage Connection in tool bar) to make a final point skeleton, and then preview the animation by clicking on Play button. Use different options present under Plugin menu to make the animation even better.
