Before we get into interleaving, let’s just refresh our knowledge a little…
An analogue video signal is constructed with horizontal scan lines. For PAL, it has 625 lines. When the camera constructs the picture, it doesn’t start at 1, and then go consecutively down to 625. It creates 1 image with just the odd numbered lines, 1,3,5 and so on and then the next image with the even numbered lines, 2,4,6 etc etc.
Each image of either odd or even lines is referred to as a field, with each field only having half the vertical resolution of the full frame. The video is interlaced.
As each field is taken at a different moment in time, if the camera or object in the frame is moving, the differences in the scan lines can be seen if the image is paused. These jagged edges are often referred to as interlacing artefacts. Continue reading →
