PAL/NTSC aspect ratio

[mikehunt69]

I have an NTSC DVD copy of Looney Tunes Golden Collection Vol. 2, and a Pal copy of Vol 3.

They are 4:3 ratio cartoons, and the PAL displays at 768x574 (0.441 megapixels) from a 720x576 frame, and the NTSC at 638x478 (0.305 megapixels) from a 720x480 source.


The PAL seems to have almost 50% more pixels, obviously the PAL is being stretched in some way, so what are the actual relative frame sizes as stored on the disc? Are they both using the full 720x480/720x576 frames?

Both are being stretched or shrunk to accommodate their nonsquare pixells to your square-pixelled monitor.

PAL does have more spacial resolution. NTSC has more temporal resolution. PotAYto, potAHto. Yes they using their full stored frame sizes, it is just your pc that wants to do the resize. Would not be necessary if going to a tv or monitor which supported nonsquare pixels.

The source is 24fps though, so not really more temporal resolution?

Cornucopia meant in the general sense, video made with a camera not sourced from film.
