FPV Camera Video Encoding Type NTSC vs PAL
The NTSC (National Television System Committee) or PAL (Phase Alternating Line) video types are generally not that big of decision to make these days since most FPV components will support both types; so you are usually covered either way no matter what you get. That said, the FPV camera is the one video component in the system that is generally one or the other so you usually have to make a decision here.
NTSC is the primary analog video system.Image wise, PAL does have a little better resolution compared to NTSC, but has a slightly slower frame rate.
If you are trying to get the very best FPV image possible, that may be one reason to choose PAL over NTSC. That said and when in doubt (if your FPV equipment can only support one encoding type), just pick the same system that is used in your country so all your video equipment is 100% compatible. If you do however have the option to use both, most people say they can detect the slight improvement in quality using PAL, so you may want to try it.
