Processing color motion picture film to yield a dye-only, “silverless” soundtrack enables reduced silver levels to be incorporated into all three color image records of a motion picture print film while still providing a good soundtrack signal in the resulting processed film. A silver halide light sensitive motion picture photographic print element is disclosed comprising a support bearing on one side thereof: a blue color sensitive, yellow dye image-forming record comprising at least one blue-sensitive silver halide emulsion having associated therewith yellow dye-forming coupler; a red color sensitive, cyan dye image-forming record comprising at least one red-sensitive silver halide emulsion having associated therewith cyan dye-forming coupler; and a green color sensitive, magenta dye image-forming record comprising at least one green-sensitive silver halide emulsion having associated therewith magenta dye-forming coupler; wherein each of the silver halide emulsions have an average grain size of less than 1 micrometer and comprise at least 50 mol percent chloride, based on silver, the silver halide emulsions in total comprise from 500-1350 mg/m2 silver, the cyan, magenta and yellow dye-forming couplers are present at levels sufficient to provide visual densities of at least 3.3 when completely consumed, the silver to dye-forming coupler stoichiometric equivalent molar ratio in each of the image-forming records is less than 1.4, and the silver to dye-forming coupler stoichiometric equivalent molar ratio in at least one of the image-forming records is less than 1.0.
