If you don’t have the budget to have this done with Teranex or Alchemist, then your best bet is the “24 at 25” option. Simply use Cinema Tools to change the speed to 25fps. You will get a frame to frame output, but your show will be 4% shorter. You may have to make it up somehow, by cutting in more material, perhaps, if the network or producer requires it.
