480p PAL vs 480p NTSC
on Oct 18, 2011 at 3:05:02 am

Hello,

I got a Canon PowerShot A1100IS

In the video capturing options, there is a PAL or NTSC

May someone tell me the difference between the 480p PAL and 480p NTSC, is there anyone better than the other in After Effects, in the term of quality or speed or whatever ?

Many thanks in advance,

The primary difference PAL is 25fps, NTSC is 29.97fps. There may also be some behind-the-scenes color tweaking that goes on that may not be perceptible to you.

You usually want to use the setting that matches the standard of the country you're in so you can hook your camera up to your tv and watch directly from it. It also simplifies the process of burning a dvd that will work with local equipment.

Web video supports a lot of different sizes and framerates. Youtube, for instance, can handle either. At that point it's more preference as to which framerate you like.

That's the in-a-nutshell answer.

Like Angelo said, PAL runs at a lower frame rate (25 fps) than NTSC (29.97 fps), but it also has higher resolution (576 lines of vertical resolution, versus NTSC's 480).

I'd agree that you'd be best served by sticking with the native format for your country.

Thanks you guys that was very much informative :)

Another question popped up ;) is there any size difference in the output since one have 25pics/frame and the other is 30/frame ?

I think this depends heavily on the compressor. The total bandwidth is the same.

NTSC has higher temporal resolution (more images per second), but each image is smaller. PAL has higher spatial resolution, but lower temporal resolution.

Here's a little math:

PAL video at 720x576 @ 25fps is 10,368,000 pixels per second.

NTSC video at 720x480 @ 30fps is 10,368,000 pixels per second.
