don't ave a cam but a litte comp savy those are two types of formats to save files... Someone will correct me I I'm wrong I'm sure
PAL and NTSC are just different formats/frame rates. PAL is a non-region 1 format for DVDs, meaning not normally found in America. PAL will have around 20% more vertical resolution than NTSC but NTSC will/can have higher framerates.
I have a few DVD players that are region 1 only and will not play PAL even if I wanted to. So my movie formats are always in NTSC.
