says, "Just like interlacing progressive content divides each frame into 
2 fields, thus doubling the frame rate, the common method of 
deinterlacing is to combine each 2 fields into 1 frame, which reduces 
the rate by 2, thus taking 50 into 25fps. You can of course double each 
final frame, but that does not provide any benefit."

Do you disagree?

Best wishes
