How Many Film Frame Question

  1. Oct 7, 2015 #1
    1. The problem statement, all variables and given/known data
    The height of motion picture film's frame is 35 cm.If 24 frame go by 1 sec calculate the total number of frames required to show ia 2h long motion picture.

    2. Relevant equations
    simple Equation which I dont need to write here I guess

    3. The attempt at a solution
    The Height of motion picture is 35 cm which is the confusing part for me.1 sec 24 frame goes mean 1 hour 24x3600 frame goes in 2 hour 2x24x3600.Is that true ?? .Is the height in there just a extra ?*

    I am not sure you included the full question. The total number of what? 35cm seems quite large for a frame?
    You calculated the number of frames in 2 hours. 2*24*3600 frames. Is that what the question is asking for, or is it asking for the length of film on a reel?

    Most motion pictures were shot on 35 mm film. A few blockbuster films also got copied to 70 mm film, both of which formats are considerably smaller than 35 cm filum.

    It would take a crane to lift a can of 35 cm movie filum.
