How do you convert PAL to NTSC?
Answer:
OK first a little background.
NTSC or National Television System(s) Committee is a standard used in the US and other 60hz countries (the origin of this so that the TV stations can be in sync with the sets via the power grid without introducing any harmonics)
PAL or Phase Alternating Line is used in pretty much everywhere else where you see 50Hz line frequency.
NTSC has 575 horizontal lines and is 29.97 fps (Frames Per Second [it was originally 30 but in the 60's when color was introduced it was lowered .03 fps to fit the extra color information in])
PAL has 625 horizontal lines and is 24.975. (again 1/1000 of the bandwidth was used for color signal)
So now how do you convert between these two seemingly different standards? The short answer is digitally.
I found the cheapest way is to buy a video capture card with multi system capability. (nearly all cards are like this because its cheaper for the manufacturer to make a one-for-all card as opposed to several different ones). The second thing you need is TV out on your video card (again most have universal output). Once you buy and install the appropriate software and hardware, follow these steps to successfully perform your conversion.
1. Set the capture card to the appropriate PAL sub-standard (yes there are standards under this standard [i.e. PAL-N, PAL-M, etc] if you don't know use trial and error).
2. Set the video card to NTSC output and turn on the TV output. Connect a television or VCR or whatever you are converting to and you should see your computer desktop on the television.
3. Open up the video capture program and turn on your PAL source. Set the video capture program to full screen mode.
5. Sit back and relax because you just built yourself a PAL to NTSC or NTSC to PAL converter for a fraction of the price of a commercial converter.
Over all look to spend under $100USD for everything including cables capture card and possibly a new video card if yours doesn't support TV out.
use some converter.
Have a multi standard TV , most modern sets now a days ( in the more civilised country's ) are multi standard, Switch on set , look in menu for system and select auto, and there you are what ever station you are tuned to the set switches to the correct standard.

Note: Pal is the superior system being a development of the NTSC , the USA is stuck with NTSC because it is too late to change it to PAL.
NTSC is subject to changes in hue ( colour ) with transmission and propagation errors which change the phase and thus the colour.
PAL is not subject to these errors as the hue is corrected line by line.Cheers Pete
