Re: [Avid-L2] Europe here calling: p50 -> p25 - i25

Years back I asked how 720P 59.94 was converted into 1080i 59.94.  I thought each frame would become a field but that was never confirmed and it was suggested that each 720 frame did not become a field but just every other frame was converted to an interlaced psf.  I'm not really sure what happens when 720P is converted to 1080i.  If I ask the same question in your 50P/25i world what is the answer there.  Does each frame of the 50P become a field?  50P means 50 discrete frames per second, correct?  Or is it two Frames from the same moment in time?.  I think it's the former not the later but please confirm or correct.  Bottom line is if each frame is a unique moment in time no matter which 50P frame  you chose there will always be a blended frame.  The big draw for 720P for ABC was that it had crisper motion like interlace does.
