Re: Downconverting Progressive HD footage to Interlaced SD footage
by Tim Kolb on Oct 20, 2009 at 1:00:29 pm

The 'techs' may be looking for field movement...which you won't have.

You only have 25 instances of movement every second. Whether it's progressive or interlaced, you won't have indications of 50 fields of movement...the two fields that the frame is divided into will both represent the same picture.

That said, putting the HD content on a SD interlaced timeline and outputting to MPEG as 25i should technically take care of it. Aesthetically, it will still look progressive.
