Introduction
Blending is bad.
The field blending process
1. A single interlaced frame. It has two distinct fields, which I will call field A and field B, happening a split second apart. |
2. The fields have been split. Field A has the even-numbered lines, while field B has the odd-numbered lines.  |
3. The actual vertical height of field A and B. Nothing necessarily bad has happened yet...  |
4. Problem number one! The fields are resized to the original height. Vertical detail is lost.  |
5. The final stage. Field A and B are blended together at different opacities. The result is a "ghosting" effect. |
