   FILMSTRIP SPEED

   This controls the NORMAL filmstrip speed.

   Current setting:
       3.75 seconds per thumbnail

   With 50 videos:
       50 × 3.75 = 187.5 seconds per complete cycle

   LOWER NUMBER = FASTER
   HIGHER NUMBER = SLOWER

   Examples:

       3.00 = faster
       3.75 = current
       5.00 = slower
