Different Formats for Different Countries -- Variable Density B&W Film
Hi:
Is it true that in the days of B&W film and optical track audio, that the films were formatted differently in different countries? When magnetic videotapes were the norm, USA and Canada used NTSC, France and Russia used SECAM, and the rest of the world used PAL. Thanks, Radium |

Is it true that in the days of B&W film and optical track audio, that the films were formatted differently in different countries? AFAIK no. When magnetic videotapes were the norm, USA and Canada used NTSC, France and Russia used SECAM, and the rest of the world used PAL. Actually the videotape systems accomodated the TV systems of the countries. It wasn't quite so simple, the (former) Soviet Union and the Warsaw pact countries use SECAM broadcast using PAL type signals. Some Arab countries used it to, hence the name ME-SECAM on mnay VCRs. The UK, South Africa and Austrailia use the same system for transmission, which is different than the other PAL countries. It still exists in DVDs. While they are YUV encoded digital video, the frame rates are 24/1001, (NTSC film), 24 (PAL film), 25 (PAL) and 30/1001 (NTSC) frames per second. This has nothing to do with zones and depending upon the player, they convert it as needed to match the TV system. Geoff. -- Geoffrey S.

By "metric size", are you referring to the size of the film or are you referring to the type of measurement used to measure the film? |

By "metric size", are you referring to the size of the film or are you referring to the type of measurement used to measure the film? "Metric sizes" are film sizes normally stated in, well, metric measures, like 6x9 and 9x12 (both in centimeters), as opposed to "inch"-sized films, like 4x5, 5x7, 8x10, etc. So, counterintuitively, 9x12 film is smaller than 4x5 film. -- Save the Planet Kill Yourself - motto of the Church of Euthanasia (http://www.churchofeuthanasia.org/) |

Metric and non-metric sheet film formats are physically different sizes.
Sheet film holders for 4x5" will not take 9x12cm sheets (they fall out) and 9x12 holders won't accept 4x5" sheets. j wrote: Radium wrote: Hi: Is it true that in the days of B&W film and optical track audio, that the films were formatted differently in different countries?
