====== Video filter Swap fields ======

It is very common that capture card/capture software swaps the fields. It will look like an interlacing effect, but on the whole image, not only on moving parts. 

This filter swaps the fields back. Here is a short example, first the image which has swapped fields:

{{:using:swap1.jpg}}

And the ouput of the Swap fields filter:

{{:using:swap2.jpg}}
