I have a DVD where a line runs horizontally through the top part of the picture.!
Question: I have a DVD where a line runs horizontally through the top part of the picture!. Is that a flaw in my DVD!?
Answers:
It is a flaw, but not in the DVD!. Before the complete standardization of motion picture cameras worldwide, the spocket holes on a reel of 35mm film negative and their relationship to the camera’s exposure frame could be anywhere the manufacturer placed them!. Sometimes the top most sprocket hole (of four per frame side) would align centered on the line between two successive exposed frames, sometimes the four sprocket holes aligned centered with a single exposed frame, as became the standard!. Prints from such a camera could be shown on projectors equipped with an adjustable framing gate (move up or down to match the framing of the print in relation to its sprocket holes)!. These prints however were a problem after camera standardization when lazy film labs duplicated these prints, either for rerelease or to create a new subnegative!. With the framing off in relation to the gates of their film printers, part of the top of the following frame might show at the bottom of the current frame when the finished print is projected on modern equipment!. That is sometimes why some 16mm reduction prints and home video presentations overcrop (show only the centermost part of the image) these prints, to keep the resulting misaligned framing from being seen!. However, this easy-way-out solution also eliminates image information on the sides (or both the sides and the top, depending on the cropping) of the original print framing!.
Recently, intending to maintain as much of the original camera image as possible, preservationists making preservation prints prepared from these misaligned (usually duplicate) prints copy the main portion of a severed frame with its corresponding orphaned sliver of a frame to again create the whole original image!. However, this creates the effect you have noticed: a portion of the image that jumps around slightly where it sometimes overlaps the portion of the image it touches and sometimes doesn’t!. That line (now at the top of the frame, in our example) is the remnant of the frameline created by the misaligned duplicate print, previously splitting the frame!. The positioning of the line reflects the amount of frame misalignment in each reel of the source film print!. For now, this is the best way to preserve misaligned prints!. You may note that the home video edition of The Cabinet of Dr!. Caligari (1920) prepared by David Shepard of Film Preservation Associates sometimes reveals just such a line!. (Shepard sometimes chose to show the entire frame with the misalignment remnant line visible and sometimes chose to crop it out!.) Another presentation with a visible remnant line is Kino International’s home video edition of F!.W!. Murnau’s The Last Laugh (1924)!. Although the line visible in such a home video can be distracting, you can see the film image that the filmmaker originally shot without excessive cropping of the image!.
Sometime in the future, when the great amount of money that would be nessessary is available, some preservationist may chose to scan the entire film and digitally eliminate the remnant line and other flaws from all of the tens of thousands of frames in such a print!. From such a corrected digital master several new preservation film negatives could be made, from which prints and home videos without the line could be made!.
