Abstract

A method of making motion picture release-print film, such as 35 mm film. The film has an enlarged frame that occupies substantially the entire width of the film that is available for the exposure of images, and the spacing between frames is minimized. Film having these enlarged frames provides an enhanced image with a minimum of film waste. An aspect ratio of 1.85:1 in the enlarged frame size is contemplated in a three perforation format. A digital soundtrack or other appropriate soundtrack replaces the analog soundtrack that occupies a portion of the available width. The soundtrack may provide for redundancy.

Claims

1. A method of making enhanced resolution motion picture release-print film, comprising:

providing a strip of motion picture film with a light-sensitive emulsion, wherein the film has two rows of perforations extending along opposite edges of the film for engagement with sprockets of a motion picture film projector;

exposing images onto an area of the film, wherein the area occupied by each image is defined by a frame having a width of at least approximately 0.88 inches that substantially occupies the available space between the rows of perforations, including space ordinarily occupied by a conventional analog soundtrack, and having a height that spans approximately three perforations or less, providing a printed aspect ratio of substantially 1.85;

1; and

placing audio information on the film, other than a conventional analog soundtrack, that coordinates sound with the images when projected by the motion picture film projector.

2. Motion picture release-print film having enhanced resolution, comprising:

a strip of motion picture film having two rows of perforations extending along opposite edges of the film for engagement with sprockets of a motion picture film projector;

a plurality of projectable images on an area of the film, wherein the area occupied by each image is defined by a frame having a width of at least approximately 0.88 inches that substantially occupies the available space between the rows of perforations, including space ordinarily occupies by a conventional analog soundtrack, and having a height that spans approximately three perforations or less, providing an aspect ratio of substantially 1.85;

1; and

audio information on the strip, other than a conventional analog soundtrack, that coordinates sound with the images when projected by the motion picture film projector.

3. The motion picture film of claim 2, wherein the audio information comprises a digital soundtrack, including a control track placed on the film outside the frames that controls operation of a CD ROM player to produce audio in synchronization with the images on the film.

4. The motion picture film of claim 3, wherein the digital soundtrack is redundant to provide redundant digital audio.

5. The motion picture film of claim 4, wherein one control track is placed on the film between the perforations along one edge of the film, and another redundant control track is placed on the film between the perforations along the opposite edge of the film.

6. The motion picture film of claim 2, wherein the width of each frame is approximately 0.945 inches and the height of each frame is approximately 0.51 inches.

7. The motion picture film of claim 2, wherein the spacing between frames is approximately 0.05 inches.

8. The motion picture film of claim 6, wherein the resolution of each image is enhanced by more than about 30 percent as compared to images defined by frames having a standard 1.85:

1 aspect ratio with a frame width of approximately 0.825 inches and a frame height of approximately 0.446 inches.

9. A method of making enhanced resolution motion picture release-print film, comprising:

providing a strip of motion picture film with a light-sensitive emulsion, wherein the film has two rows of perforations extending along opposite edges of the film for engagement with sprockets of a motion picture film projector;

exposing images onto an area of the film, wherein the area occupied by each image is defined by a frame having a width of approximately 0.945 inches and a height of approximately 0.51 inches, whereby the width of the frame occupies substantially the entire available space between the rows of perforations, including space ordinarily occupied by a conventional analog soundtrack, and the height of the frame spans approximately three perforations, providing a printed aspect ratio of substantially 1.85;

1; and

placing audio information on the film that coordinates sound with the images when projected by the motion picture film projector, wherein the audio information substantially does not occupy said available space between the rows of perforations.

10. Motion picture release-print film having enhanced resolution, comprising:

a strip of motion picture film having two rows of perforations extending along opposite edges of the film for engagement with sprockets of a motion picture film projector;

a plurality of projectable images on an area of the film, wherein the area occupied by each image is defined by a frame having a width of approximately 0.945 inches and a height of approximately 0.51 inches, providing an aspect ratio of substantially 1.85;

1; and

audio information on the strip that coordinates sound with the images when projected by the motion picture film projector, wherein the audio information substantially does not occupy said available space between the rows of perforations.

11. A method of making enhanced resolution motion picture release-print film, comprising:

providing a strip of motion picture film with a light-sensitive emulsion, wherein the film has two rows of perforations extending along opposite edges of the film for engagement with sprockets of a motion picture film projector;

exposing images onto an area of the film, wherein the area occupied by each image is defined by a frame having a width of at least approximately 0.9 inches and which substantially occupies space between the rows of perforations, including space ordinarily occupied by a conventional analog soundtrack, and a height that spans approximately three perforations or less, providing an aspect ratio of substantially 1.85;

1; and

placing audio information on the film, other than a conventional analog soundtrack, that coordinates sound with the images when projected by the motion picture film projector.

12. Motion picture release-print film enhanced resolution, comprising:

a strip of motion picture film having two rows of perforations extending along opposite edges of the film for engagement with sprockets of a motion picture film projector;

a plurality of projectable images on an area of the film, wherein the area occupied by each picture is defined by a frame having a width of at least approximately 0.9 inches and which substantially occupies space between the rows of perforations, including space ordinarily occupied by a conventional analog soundtrack, and a height that spans approximately three perforations or less, providing an aspect ratio of substantially 1.85;

1; and

audio information on the strip, other than a conventional analog soundtrack, that coordinates sound with the images when projected by the motion picture film projector.
