The 24 fps rate of film, and the 25 fps rate of PAL both provide visibly poorer temporal resolution, and motion is just not smooth. The flicker is also quite visible and annoying to many. 2. The color coding of PAL is actually inferior to NTSC, as it takes more complex receivers to get an adequate result, and it still often results in intensity fading when phase errors occur. (The PAL folks thought that hue errors were worse than satuation errors.) Ever since the early 70's, when electronics reached the stability needed, NTSC has delivered better color. I have watched both, and the difference is clear. 3. Those who have accurate pitch do hear the substantial pitch change of the sound of films moved from 24 to 25 frames/second, and some find it annoying, to the extent that it is often digitally corrected nowdays. 4. Anamorphic widescreen from DVDs does not increase the horizontal resolution. It simply stretches the pixels wider. 5. Several efforts have been made to convert movies to 30 or 60 frames per second, and the results have been reported as vastly better than the current too-slow standard. Visible film grain is reduced, sharpness and brightness appear better, and motion is substantially smoother. The resulting image is said to have much more emotional impact due to its greater realism. Find some reviews of the 1950's Todd-AO version of Oaklahoma done at 30 fps comparing with the 24 fps version -- the faster rate really makes up a difference. Summary: One should not break video to be compatible with inferior systems based on film, or matching lower frequency power lines. Several points: 1.

But you can write a full article on that? I wouldn't change your glasses if i were you, they are just fine to make sense of what you wrote.
