A crossfade or blend between two videos is particularly easy to accomplish in Jitter using OpenGL. (One can also blend two videos without GL, using the jit.alphablend object. The GL implementation is more efficient, because the blending computation takes place on the computer's graphics card instead of its CPU.)
The easiest way to cut a two-dimensional matrix into equal-sized rectangular segments is with jit.scissors. You initialize the jit.scissors object's rows and/or columns attribute, and the object will be created with enough outlets to send each segment out a separate outlet.
Simple linear motion in 2D animation is achieved by interpolating between two points and successively drawing an object at each intermediate point, as demonstrated in the example on Animating 2D graphics.
This patch allows you to try different exponentialities of fade-in/fade-out of a video.
One way to combine text and video is to write text in jit.lcd as demonstrated in the example “Draw shapes and text
In working with video and animation in Jitter, it’s important to remember that the effect of continuous motion is achieved by successive discrete images, each somewhat different from the preceding one. You can create that effect in 2D animation by repositioning graphic objects for each frame, according to a particular trajectory, such that the objects seem to be moving.
The jit.lcd object understands a variety of command messages for drawing simple things such as lines, geometric shapes, text, and pictures any place in a matrix.
One way to describe a color is in terms of the intensity of three components: red, green, and blue. This descriptive form is known as RGB color space. (It’s called a color space because you can think of each of the three color components as representing a dimension in a 3D space.
