Io HD – Interlaced?

[Carsten Orlt]

its really quite simple.
interlace means that that first the odd lines are written 1,3,5,7,9…..
and after that the even lines in a second run 2,4,6,8,10…..
In Pal this happens 50 times a second producing 25 complete frames per second.
Now imagine a camera chip that takes an exposure on each of those 50 cycles only writing either odd or even lines at a time, and you would look at one complete frame you would see a temporal difference between the odd and even lines (think of a ball flying left to right. the even lines would show the ball a bit more to the right then the odd lines on one frame)
But you can also expose all lines of the camera chip at the same time store the information in a temporary buffer and then write first the odd lines and then the even lines to tape. If you do this 25 times per second you effectively have a progressive frame. That it was is called Progressive segmented frame.
