Moves red, green and blue channels backwards or forwards in time individually. This creates a trailing effect on moving objects, or can create a chromatic aberration style distortion.
- Red Shift: Sets the number of frames by which the red channel is shifted from the current frame number. Positive values will take frames from later in the clip, while negative values will take frames from earlier in the clip.
- Green Shift: Sets the number of frames by which the green channel is shifted from the current frame number. Positive values will take frames from later in the clip, while negative values will take frames from earlier in the clip.
- Blue Shift: Sets the number of frames by which the blue channel is shifted from the current frame number. Positive values will take frames from later in the clip, while negative values will take frames from earlier in the clip.
- Alpha: Selects the frame that will be used for the alpha channel. By default it uses the Current Frame. Average will calculate the average of the values of all three color channels, and use that frame. Red Shift, Green Shift and Blue Shift will take the value from the selected channel, and use that frame as the alpha. The alpha setting applies when you are working with a layer that included alpha transparency. On standard video, the alpha setting will have no effect, since the entire frame is completely opaque.
