FurnaceCore has three effects based on global motion estimation (GME).
FurnaceCore effect based on global motion estimation calculate a four-corner pin, which finds the best fit of one image onto another, and then apply that pin. These effects differ in how that corner pin is calculated and to which image that pin is applied. This chapter describes the general idea behind these plug-ins; for more detailed information on each plug-in, please read their individual chapters.
• F_Align - which lines up two shots of the same scene, by finding a corner pin from each source clip frame to the corresponding reference clip frame. For example, you can use this to align two separate but similar steady cam shots of the same scene.
• F_RigRemoval - which removes unwanted objects (rigs) from image sequences without accurate rotoscoping or keying to produce a clean plate.
• F_Steadiness - which removes motion from a single clip, by calculating a pin that either locks all frames in the clip to a single reference frame, or smooths that motion out over a window of frames. For example, you can use this to remove camera shake.
