surprising how much power they get out of an engine that doesn't look so very big yes about a thousand cars in the floor engines together hano thousand each about four thousand or so all told it looks like i'm getting curious at the right time you seem to know the answer i'm an engineer automotive an automobile engine is just the man i didas by name is alan reynolds is mine i don't want to bore you but there are some things i'd like to ask you won't bore me by talking about and you see i'm a an animation director you mean you draw cartoon comedies for the movies i try we're doing a cartoon with a bunch of little imps using an automobile to win a war everything is swell except we get in trouble whenever we try to show the engine i'm on my way off the coast for a vacation so i ought to forget about engine cartoon stuff sounds interesting i always wondered how they did it so maybe we can dicker of it how about spending a day or two at the studio that sounds ok to me we've got a kind of way engine out there that might help you suppose i have a sent over to your place that's fine and when you come over to the studio i'll show you what we finished i think is pretty clever the way you fellows combine cartoon think yours with something look as real as that automobile would make tracings from photographs of a real car for longer scenes but when it came to the sequence inside the engine we began to have troubles and i think the kind let's have one of the little fellows on each valve they can be in the special uniform of a mechanized unit a great idea and then we'd make the impasse in the shape of valves and then have them jump up and down the action will make them open and close the chamber  and because the fuel comes directly into the head that means greater economy how about having an old miser amp in charge of doling out just the right amount a stinky looking fellow with whiskers w just hates the idea of waste that's ok the valve mechanism is specially designed for quiet operation just like everything else on this engine why not have monitor amps walking around with quiet please signs they will make a unnatural say when you get to the place where the general calls for more speed why don't we turn this thing into an airplane engine block the in skull so fast they're just a blur we find out the shot and change last possible ounce they can get and fuel economy at the same time for long range operation as a matter of fact all the engines are whole major speed records are this same valve and head construction we have enough trouble making these drawings look like an automobile engine without asking from wrong that's going back to this one here this engine has ninety eight hours power for plenty of pep performance why not have one of the amps and charge of the horses someone who could really handle them but would you think of a chariot driver here doing fine will make them up big muscular guy with a whip ok and this engine has quite an oily system for distinct types of ironing in fact to meet the needs of different operating parts most efficiently and economically soul some of the image could be dressed like a cruel boilers with little sprays and cans sounds all right to me once a space fall that's the water jacket what i want to know is how you get the sounds of the engine and life has to go with your pictures that's easy let me show you we use a regular actor whose voice fits the personality of the character we've created in this film we make a note of how much film is taken for every syllable that is how many frames are separate pictures there are sixteen frames to every foot of movie film so if it takes twelve frames to complete a word or a piece of action the  knows he has twelve drawings to make he uses his own like movement as a guide when he draws a character speaking animators don't have to be crazy but it helps this is how the animators checked the motion in the drawings before they photographed we have a timing device which gives our musical director his temple we photograph the drawings with a moving beater showing on the edge we check our action in recall of the music to this temple didn't realize it took that many the cells are put together like an assembly line in their photograph one by one over the backgrounds
