Capturing in Vdub live with filters and skipping rgb24 conv

[mammo1789]

Hi
I have seen in vdub capturing menu "Filter chain", but I never put to much attention to it. Today i tried to capture from my vcr to the pc card and in under the menu selected enable filters and then there is skip 24 rgb conf like on the picture i captured the file while enabling the MSU noise reduction filter in vdub ( how by the way can work real time because it uses gpu) and read it with mediainfo it says yuv video but i cannot notice any chroma or grain noise.

My question is what vdub do when you select the filter chain menu and enable in the list you chose for example very fast filters and apply them, does it engage them when capturing and if you chose skip 24 rgb conv does it not do any color conv while capturing?
