Hi

I am capturing a CCIR 720x576 lines (Black and White) standard PAL signal with the AJA IO HD.
Right now I am capturing via Composite In (CVBS) and I am wondering if I would gain in quality if I captured via SDI, or the Y of Component (Black and White signal). Of course I would need to know if it possible to record PAL via SDI or Component(Y).

Thanks for the time
