Video stimulus type

[ransona]

This stimulus type implements visual stimulation with an arbitrary image sequence, loaded from a file or folder with images with the following naming convention frame-***.bmp (or other compatible image format). Multiple videos can play simultaneously and each instance can be parameterized individually with different orientation, position, speed and onset/duration.

Parameter Messsages

• Video
  • Placement
    • Orientation the angle of the video quad, in degrees
    • Width the extent of the video quad in the horizontal direction, in degrees of visual field
    • Height the extent of the video quad in the vertical direction, in degrees of visual field
    • LocationX the horizontal position of the gratings, in degrees of visual field
    • LocationY the vertical position of the gratings, in degrees of visual field
  • Parameters
    • Loop one if the video should loop, zero otherwise
    • PlaybackRate the frame rate at which images from the sequence should be played, in Hz
    • Name the name of the image sequence to play
  • Onset: the delay until the video appears, in seconds
  • Duration: the time during which the video is visible, in seconds
