When showed on a video projector (such as for giving a talk), some of Audrey's stimuli are very dark so that the mouth is invisible.
To fix this, use iMovie to brighten the clips. The following parameters were used:
exposure/brightness/contrast/saturation 156%/ 53%/ 57%/ 200%
Alternately, use the Auto button in iMovie. This sets the following
Levels (left slider) = 0 Levels (Right slider) = 70%
The new stimuli we recorded were edited on Final Cut Pro, cut to 2 seconds in length with the onset of the sound at the mid-time point. They were exported as .mov files.
