Loop/Morph Animation

This animation is created from a list of keyframes by first “looping” each keyframe and then next morphing from that keyframe to the next keyframe. So the animation sequence for just two keyframes is:

Loop keyframe 1
Morph keyframe 1 into keyframe 2
Loop keyframe 2
Morph keyframe 2 back to first keyframe 1

What is looping?

If you open the Triangle Editor for a keyframe, the list of transforms each have a Rotates checkbox. When checked that transform will be “looped” during a Looping animation. If unchecked, then that transform is unchanged through the course of the Looping animation. Note: if no transform has its Rotates checkbox checked, the Looping Animation does nothing to the fractal.

On the Triangle editor, you can use the Animate CCW or Animate CW buttons to see the effect of the Looping Animation. You either need to specify the degrees of rotation (in the ComboBox below the set of buttons) or you can press the Interpolator button next to the Animate buttons to see an interpolated set of fractals with the Looping Animation.

The Looping Animation applies a rotation to the transform’s triangle (but only if its Rotates checkbox is checked).

Loop Morph Animation Pane Controls

Video frames (per Animation segment) for Looping and Morphing

Looping: Number of video frames to interpolate for each Looping segment.
Morphing: Number of video frames to interpolate for each Morphing segment
Total: Number of video frames total to interpolate for both Looping & Morphing.
Looping %: Slider for the percentage amount of Looping versus (Looping + Morphing).
Smoothing: Determines if spline smoothing is applied.

High Quality Video

For each keyframe, two animation segments are created, one for looping and one for morphing. So if there are 6 keyframes, there will be 12 animation segments. You can choose to break up the rendering by just rendering a subset of the animation segments.

The actual number of interpolated video frames for a single animation segment is set with the Video Frames controls. You can create a long video in short pieces and merge them together using Quicktime Player or iMovie. a 5 minute video with a 30 second frame rate will have 9000 rendered image frames in it.

You have the choice of directly creating a video or saving the interpolated frames to another flame file. If saved to another flame file, you can use the File menu > Render Keyframe Image Batch later to create a batch of image frames and create a video then.

Make Video button: Opens the Direct Video Rendering panel to make Quicktime movie.
Make Frames button: Opens the Direct Video Rendering panel to render video frame image files into a folder.
Start slider: The starting index of the first animation segment to interpolate (first = 0).
Length slider: Number of animation segments to interpolate.
Rendered Frame Count: The number of video frames that will be rendered based on the Length value.

As-Is Video Animation Pane Controls

This pane is for creating video from pre-interpolated source frames. No extra interpolation is applied.
