From my understanding, your 3D array (10x240x132) is in face a 10 page 2D array (240x132). The dimensions of the 3D array are row, column, and page. So each page (3rd dimension of your array) includes one second of data in a 2D array (240x132).

Is there a specific way you are wanting to display the frame grayscale data? Do you want to see 10 separate 2D array's, each containing one second worth of data (240x132)?

You can use the Index Array primitive function and use the 'index (page)' input to specify which page you want to extract from the 3D array. The example below is by no means efficient because it is not scalable, but it should help illustrate what to do:
