see http://www.poynton.com/papers/YUV_an...e_harmful.html Abstract The notation YUV, and the term luminance, are widespread in digital video. However, digital video almost never uses Y'UV color difference components, and never directly represents the luminance of color science. The common terms are almost always wrong. This note explains why. I urge video engineers and computer graphics specialists to use the correct terms, almost always Y'CBCR and luma. |
Victor: of course it is. I must have typed that too fast. I edited my original
post to reflect the correct number of 25. Thanks for spotting that! p.s. the fields number of 50 was correct |
Before you run out and buy a PAL camera, be aware of some of the drawbacks. To go to DVD you need to deinterlace the footage and slow it down 4% so in essense you're shooting at 25p. 25p or 24p cannot handle the quick handheld jerkyness that most of us get when we grab a camera and start shooting. If you are not tripod, dolly tracking or steadycam shooting your footage it's going to look unsteady. Also, there is a lot of 60 hertz flickering in US lighting, especially when there is flourescent lighting. Many people are now using daylight temperature screw in flourescent lights in place of old fashioned power hungry bulbs. Shooting NTSC you'll never notice this because the 60i frame rate matches but shoot PAL and you'll see lights flickering everywhere. Shooting PAL makes a lot of sense if you're in a PAL country or if you're shooting a lit movie with compatible lighting and your final output is 100% going to be film, but I wouldn't do it otherwise unless I lived in a PAL area.
