1. What were tee reasons why 60 frame interlaced chosen for over the air broadcasting? How did the introduction of color factor in?
The interlaced format was introduced as a result of the attempt to reduce the necessary bandwidth. The increasing popularity of television in modern society meant that letting the VHF die off was impractical. Thus, the race to achieve the certain color standard began. Color TVs adopted the separation of luminance and chromas which means the separation of colors versus their brightness. I order to prevent the color standard from interfering with the audio signals, the frame rate was reduced by 0.1%. Therefore the common frame rate is in fact not exactly 60 frames per second, but rather 59.94 fields per second.
2. How do you convert a film to television? What is 3:2 pull down?]
In order to allow 24 fps to fit into a 60 i video format, it must be split up into fields known as the 3:2 pulldown. However, this is not a completely practical way of converting files because they lead to jitters every 2 frames per 4 frames. Thus, in order to maintain the quality of the video, it is optimal that one shoots in 24 fps to begin with.
