Spectrum Analyzer: Audio and beat slider for the animation of visuals. See Tutorial Coupling Video with Effects and Audio Signals. (A)
Storage Area: Minimize a clip by dragging it to the exterior area. (B)
Work Area: Maximize a clip for processing by dragging it to the center area. (C)
New Clip: A new clip will be created. The new clip has the standard footage as selected in the 'Windows' settings under 'Standard Clip/Timer'. (D)
Clip: An open clip in the work area. Open the clip settings by dragging the lower right corner (see arrow). Create a layer (send the clip to the Layermanger) by dragging the clip to the Layermanager, or by clicking on the 'Plus' sign. (E)
Expression: Hold Shift and drag any moving fader (e.g. Spectrum Analyzer or Clip Progress) to any visible parameter (e.g. Layer or Effect parameters) to connect the two values through an Expression. (A)
The movement of the first bar is going to influence the value of the second one.
The Expression can be minimized and recalled: to see the expression, double click on the red part of one of the selected bars. To minimize it, just hit the minimize button or double click on one of the bars again.
Expression Editor: Open the Editor with a double click on the Expression. (B)
The user can modify the mathematical properties of the relation between the two connected values. Base and Range can be used to calibrate the responsivity of the Scale to the low frequencies of a sound.
Example of sound to light calibration:
- 1. Play a video and connect with shift+drag&drop, a moving channel of the Spektrum Analyzer to Scale.
- 2. Open the Expression Editor, bring 'Range' to '0' and move 'Base' until you get close to the target default value (Scale:100).
- 3. Now, moving the 'Range' up should increase the influence of the sound on the video 'Scale'.
Tips: An expression can be stored and recalled in a Patch, it can be paused. It can be used in chain and also to connect different parts of the software! (e.g. Spectrum Analyzer - Scale - Keystone - IO Animator)
