VideoFX

VideoFX editor

The picture treatment. One video inlet, one outlet, and a rack of knobs that move, resize, spin, colour and break the frame on its way through: position, scale and rotation on the top row, brightness, contrast, colour, hue and invert on the bottom, a pixelate knob that coarsens the image down to a mosaic and a mirror that folds the frame across its middle.

Every knob is an ordinary param, and that is the point: put a Follower on Scale so the kick pushes the picture at you, an LFO on Rotate for a slow spin, a Sequence on Hue for a colour cycle in time, or map the lot to a controller. Chain two for a transform and a colour stage that automate separately, or put one before a VideoMix and one after.

Scalehow big. 100% is as it came, 200% twice as big, 0% collapses it to a point.
Rotatethe spin, in degrees, around the centre of the frame.
Pixelatehow coarse the mosaic is. 0% leaves the picture alone; 100% is a handful of blocks across.
Mirrorfolds the frame: Left copies the left half onto the right, Top the top half onto the bottom, Both does both.
