Abstract

A film to tape transfer system is disclosed for use with film of the type including a transparent magnetic layer on the back of the film. The coated film negative and a fullcoat, oxide coated, sprocketed sound track are fed to a tele-cine camera which inputs a VCR to produce a videotape record of the film. An SMPTE time code generator is built into the system to simultaneously write a time code on the picture track, the sound track and on the videotape. A keyboard is included to enable the operator to enter all pertinent information such as production number, camera number, director, cameraman, etc. as the films are being run.

Claims

1. A film to tape transfer system comprising

a console;

means operatively associated with the console for drawing a camera negative film having a magnetic coating across the console;

means operatively associated with the console for drawing a sound track film having a magnetic coating across the console;

transfer means operatively associated with the console and configured to receive the camera negative film and the sound track film, and adapted to produce a videotape recording of the camera negative film and the sound track film as the camera negative film and the sound track film are drawn across the console;

means for generating a time code signal; and

recording means operatively associated with the time code generator means and the transfer means to simultaneously provide a time code signal upon the magnetic coating of the camera negative film, upon the magnetic coating of the sound track film and upon the videotape recording.

2. The transfer system of claim 1 wherein the time code generator means is an SMPTE time code generator.

3. The transfer system of claim 1 wherein the recording means comprises a camera negative recording head, a sound track recording head and a videotape recording input for simultaneously providing the camera negative film, the sound track film and the videotape recording with the time code signal, respectively.

4. The transfer system of claim 1 wherein electronic circuit means, keyboard means and register means are operatively interconnected with said time code generator means so that time code data can be entered by the keyboard and stored in the register means.

5. The transfer system of claim 4 wherein a counter is operatively connected to the electronic circuit means for the display of time code data.

6. The transfer system of claim 1 wherein the time code signal is applied to the camera negative film, the sound track film and the videotape recording as the videotape recording is being produced.

7. The transfer system of claim 1 wherein a video camera is operatively associated with the transfer means so as to produce the videotape recording.

8. The transfer system of claim 7 wherein the recording means comprises a video recorder operatively connected to the time code generator means to provide the videotape recording with the time code signal.

9. The transfer system of claim 7 wherein a color monitor is operatively associated with the video camera.

10. A film to tape transfer system comprising

means for drawing a camera negative film with a magnetic coating through a first transfer path;

means for drawing a sound track film with a magnetic coating through a second transfer path, wherein the first and second transfer paths are synchronized for simultaneous operation;

tele-cine camera means for receiving images from the camera negative film and sound from the sound track film, and for producing a video output signal;

a video recorder adapted to receive the video output signal from the tele-cine camera means and to produce a videotape recording of the sound from the sound track film and the images from the camera negative film;

time code generator means for generating a time code signal; and

recording means operatively associated with the time code generator means to simultaneously provide the time code signal upon the magnetic coating of the camera negative film, the magnetic coating of the sound track film and the videotape recording.

11. The transfer system of claim 10 wherein the camera negative film drawing means comprises a first feed reel and a first takeup reel in spaced relationship.

12. The transfer system of claim 11 wherein the sound track film drawing means comprises a second feed reel and a second takeup reel in spaced relationship.

13. The transfer system of claim 12 and a circular sprocket intermediate the first and second feed reels and the first and second takeup reels, for receiving the camera negative film and the sound track film.

14. The transfer system of claim 13 wherein a portion of the first transfer path forms a first arc about the circular sprocket.

15. The transfer system of claim 14 wherein a portion of the second transfer path forms a second arc about the circular sprocket.

16. The transfer system of claim 15 wherein the recording means comprises a first recording head positioned adjacent to the first arc and a second recording head positioned adjacent to the second arc.

17. The transfer system of claim 10 wherein the time code signal is applied to the camera negative film, the sound track film and the videotape recording as the videotape recording is being produced.

18. The method of transferring images formed in a camera negative film having a magnetic coating and sound recorded in a sound track film having a magnetic coating, to a videotape recording, comprising

drawing the coated camera negative film and the coated sound track film across a console and through a tele-cine camera means;

transferring the images on the camera negative film and the sound on the sound track film to the videotape recording, as positive images;

generating a time code signal; and

simultaneously recording the time code signal upon the magnetic coatings of the camera negative film and the sound track film, and upon the videotape recording.

19. The method of claim 18 further comprising the step of keying in, by means of a keyboard, preselected information while the time code signal is being recorded.

20. The method of claim 19 further comprising the step of displaying the keyed in information.

21. The method of claim 18 wherein the time code signal is applied to the camera negative film, the sound track film and the videotape recording during said transferring step.

22. The method of claim 18 wherein said transferring is performed by means of a film to tape transfer apparatus, and further comprising the step of editing the videotape recording off-line of the film to tape transfer apparatus and in accordance with the time code signal applied to the videotape recording.

23. The method of claim 22 further comprising the step of using the edited videotape recording and the associated time code signals to provide an edited camera negative film.
