// Example 1:
// If one clip has 10 frames (1 to 10), and you specify
// first_frame_to_process = 4, last_frame_to_process = 7 and interval = -1,
// then you will get a clip that contains frame 1, 2, 3, 8, 9 and 10.

// I you specify first_frame_to_process = 1, last_frame_to_process = 10 and
// interval = -4, then you will get a clip that contains frame 1, 5, 9.
// Example 3:
// If you specify first_frame_to_process = 4, last_frame_to_process = 7 and
