Can someone tell me what does Vertical Reduction actually does and the advantages and disadvantages of using Vertical Reduction?
Thanks. |

It would be useful to deinterlace the video while capturing. Capturing at full height and using the Vertical Reduction will blend together the lines and would probably give you better quality than straight 320x240 (or it's PAL equivalent) capture.
I believe it is simple resize that halves the vertical res using Linear or Cubic depending on your choice.

jcsston is right, but some short words:
You capture Full PAL or NTSC resolution and reduce the resolution during capturing ("on the fly" to the half vertical reduction, so you dont have to deinterlace after capture but you have all the information that you can get. (vertical)

Which one is better? Linear or Cubic or it depends? |

Depends 
My experience: good source cubic, bad source linear
But cubic needs more cpu power as i remember
