Description

Method and device for image-accurate electronic film dubbing.

The professional film usually uses the pilot frequency method according to DIN 15 575 for synchronous sound film recordings. For the later film scoring will With this method, the original sound on perforated magnetic film (16 or 17.5 mm). The pilot frequency becomes the motor control of the Perfo. Machine used. As a result, after the transfer there is a perforated image and a perforated image Sound carriers that can be further processed synchronously in this way. For the amateur sector with all 8 mm formats and in some cases also with the 16 mm models, the pilot frequency method is used too expensive and therefore not in use.

For these formats there has been a projector control method for several years, the uniform tone system.

The pulses used for this are used for controlling the projector needed. Compared to the pilot frequency method, the standard tone system is absent The transfer of the sound to perforated magnetic film is also not an analog process known about this. Due to this fact, image and sound carriers cannot be left without further process further synchronously.

The main obstacles in setting the individual scenes to music without perforated magnetic film consist of the following: Through the offset of sound and Impulse head one does not cut the proekor control impulses belonging to the sound. Without Aids are not to localize the impulses on the sound carriers. When cutting The tapes do not ensure that the pulse spacing between two sound scenes is complied with and X or pulses are partially cut.

For dramaturgical and / or recording reasons, in film frames are usually cut at the beginning and end of a film scene. Without suitable It is not possible to use aids, especially with the standard tone system, even image-accurate to cut the sound, since there is only one projector control pulse for every four film frames is used. This deficiency also applies when between the tone and impulse head there is no offset.

With e.g. mechanical sound clappers, sound film recordings are synchronized not ensured during the film showing, as there is no synchronization between the camera and profector is given. With this coupler method, too, dubbing is problematic and largely dependent on the individual's ability to react. For example, point noises or the like to be able to set to image exactly, there is a lack of the necessary device, the a picture-accurate setting allows as far as possible without any problems.

Environmental influences often do not allow qualified sound recordings to make at the film location. The playback technique can eliminate such influences, however, due to the lack of equipment and procedures, it has not yet been applicable to cine film.

The invention has the object, with the help of a yet to be presented Method and device to remedy the above-mentioned inadequacies by using known tape recorders equipped with a start / stop remote control accurate film-synchronous film scoring can be carried out. The procedure should take into account the stringing together of synchronous and asynchronous sound scenes of the film editing, also enable film-synchronous playback dubbing. Furthermore a combination of both scoring methods should be possible.

When setting the playback to music, it should be ensured that both the sound sync scene on sound sync scene as well as sound sync scene on asynchronous scene lined up picture-exactly can be.

According to the invention, a method is used to achieve this object which characterized in that a home tape recorder known per se with start / stop remote control at any point additionally attached stereo pulse head or via a sound head equipped with four magnet systems, audio frequency frame pulses recorded on the sound carrier during filming or sound preparation that are the information carriers for the later film and sound editing.

According to the invention, the frame pulse series for the respective Scoring type set differently on the sound carrier. Accordingly, the inventive The method is further characterized in that a) in the fully synchronous playback recording alternately on one of the two tracks impulse series are played, whereby the the respective end of the series of pulses and the beginning of the series of pulses overlap on the two tracks appear, b) a track over a part of the partially synchronous playback recording or is provided with asynchronous pulses over the entire length of the soundtrack, there where sync fade-ins are to be dubbed additional sync impulses on the still free track and with c) scene-wise synchronous and asynchronous dubbing the series of impulses are recorded on one of the two tracks prior to setting to music.

According to the invention, a device is used to carry out this method, which is characterized in that the sounding pulse series coming from the tape brought to the same level in two well-known amplifier and rectifier stages that is required for further processing in the device and these pulse series via a program selection to a double preselectable counter, the controlled via the respective area code assigned signaling block, the in turn, the delayed flip-flop "tape recorder" and the delayed flip-flop "Impulse" switches, whereby the flow of impulses to the tone generator and thus to the impulse head of the tape recorder is released.

According to a further feature of the invention, the two are per se known delay levels with different delay times for tape recorder and pulses, which ensures that all commercially available tape recorders with remote control device regardless of the size of the switching delays Facilities are to be used, as in the case of scene-wise synchronous dubbing the delay time of the tape recorder and thus the delay time of the delay step "Impulse" corresponds to a lot of film frames at the beginning and at the end of each synchronous Scene are cut and accordingly with scene-by-scene asynchronous dubbing Lots of asynchronous frame pulses available before and after each asynchronous scene stand and the pulse flow to the frequency divider and tone generator and thus to the pulse head of the recording device is only then released or via contacts of the delay stage is blocked when the recording device has been running for half an image period or is half a picture period before the stop.

Another feature of the invention is characterized in that the tone and the impulses for who made which Reasons whatever Film frames cut at the beginning and / or end of a sound film scene are not the same Tape recorder are leaked because the delay flip-flops only then can switch when the number of received in the dubbing device Frame pulses with the position of the respective preselection for tape recorder start and stop covers.

According to the invention, the scene-by-scene setting can be performed after each sound scene be interrupted, ensuring that the pulse spacing between two Scenes are retained because the respective content of the frequency divider is displayed via a small indicator light can be read out with the help of a button, using the same button before renewed Start of scoring of the frequency divider according to the previously read content is to be set.

Furthermore, according to the invention, the "Signaling first." Preselection '§ with the scene-wise dubbing via the program relay an impulse given the scene counter, which shows the current state of the scoring.

For fully synchronous playback recording, with the help of an additional device the impulse fades according to the invention thereby recorded congruently, in the impulses already recorded on a track when the camera is started first partial or full pulse a FF switches over, whereby at the same time via a NAND element the further pulse flow to this FF is blocked and the pulse flow for whole Pulses released via a NAND element to a known monostable multivibrator becomes, after the end of the first full extended pulse another FF switches after switching via a NAND element blocks from further impulses and controls a relay via a transistor, the contacts of which control the camera motor Power supply, whereby it is ensured that the circuit has a with the Camera trigger connected toggle switch before and after dgsep ~ B confirmation in idle state is.

Furthermore, this circuit ensures according to the invention that the impulse cross-fades recorded in this way via a Nand link with the help of the impulse dubbing device are counted, which means that the film is cut for fully synchronous playback dubbing is ensured. Incidentally, the pulses already recorded become each Impulse track made visible via a lamp, whereby the individual playback scenes so the sequence can be taken on, as it is from the respective film location in the order required.

According to a further feature of the invention are for playback dubbing the series of impulses of the one track in the setting to music via the program selection twice Preselectable counter supplied, the impulses of the other track are sent via a contact of the program relay is fed to the scene counter if the start / stop cable is not connected and counted in each case, the numbers thus determined being information for the film and sound editing, according to which the area codes are to be set for the setting. Furthermore, the impulse dubbing device is used between scene-wise and playback dubbing not adjusted again because the frame pulse flow during playback dubbing by the playback position of the program relay contrary to the scene-wise dubbing Via the contacts of the delayed flip-flop "tape recorder" to the frequency divider and tone generator is performed.

Embodiments of the devices for carrying out the method are illustrated on the drawing, it shows: Figure 1-5 a sound carrier on which the possible pulse arrangements are shown, Figure 6 is a schematic diagram the interconnection of dubbing, impulse dubbing and recording device, figure 7 shows the circuit diagram for the impulse dubbing device; FIG. 8 shows the circuit diagram of the additional device for playback recording.

In FIG. 1, the arrangement of the pulses 7 corresponds to a fully synchronous one Playback recording. Area 3 corresponds to a pulse cross-fading of the end of the first scene 4 and the beginning of the second scene 5. The impulse dissolve 3 is achieved by putting the tape around the area after recording the first scene 4 3 is rewound. From this point on, the second scene 5 is filmed.

The same applies to 6, etc.

The area 3 and 6 etc. is thus filmed twice.

After counting the impulses 7 of the impulse fade 3, 6 etc. the film frames, rotated twice for sound, can either be at the end of the first scene 4 or at the beginning of the second scene 5 or partially cut from both scenes will.

The distance between sound head 1 and pulse head 2 can be arbitrary.

Due to the offset of sound head 1 to pulse head 2, this belongs Sound event 8 to the impulse area 9. Both the area 9 and the area The length of 8 corresponds to one image period. The pulse 7 is in its length <half a picture period.

In FIG. 2, the arrangement of the pulses 7 corresponds to a partially synchronous one Playback dubbing. On the upper pulse track 10, as far as a partially synchronous Playback dubbing is desired, asynchronous frame pulses 7 recorded throughout. On the lower pulse track 11 are at the points of the canned audio via the camera contact Set individual image pulses 7, which should appear synchronously with the projection during the projection and thus represent synchronous areas 12.

Area 13, for example, is an asynchronous area.

The area 14 are any film frames to be removed at the beginning The synchronous scene 12, the Beri <4 15 are ever! tually removed film images at the end of the synchronous scene 12. The definition of areas 14 and 15 results themselves from viewing the synchronous scene 12 in the christening image viewer. The ones to use in the movie Film images and pulses of the synchronous scene 12 then correspond to the synchronous area 16. If the synchronous film recording permits, the areas 14 + 15 W can be zero be. This would mean that the entire sync scene 12 is used.

Figure 3 illustrates a combination of the pulse arrangements of the figures 1 and 2. On the upper pulse track 19 are asynchronous frame pulses up to the area 17 set with the impulse dubbing device 30. The one on the lower pulse track 20 Pulse sections drawn correspond to synchronous pulses 7 that are transmitted via the camera contact were triggered. Up to area 17 it is a partially synchronous sound recording, in Figure 2, from area 18 onward, a fully synchronous playback recording such as in FIG. 1. Thus, from area 21 onward, there are also synchronous individual image pulses on the pulse track 19 played.

FIG. 4 shows a scene-wise synchronous recording. On the pulse track 22 are synchronous frame pulses 7 during the recording of the original sound, the same happens for asynchronous dubbing on the pulse track 23 where asynchronous frame pulses Z are recorded.

Figures 1 to 4 show the pulse arrangements as they are in a Four-track tape recorder with the two audio tracks 7 a are given.

FIG. 5 shows the possible arrangement of the pulses 7 in a two-track tape recorder. Stereo dubbing is provided that the network-independent dubbing device 24 is a two-track device can not.

According to Figure 6, between the dubbing device 24 and the recording device 25 the Tonüberspielkabei 26 attached in a known manner. From the stereo pulse head 27 of the transfer device 24 becomes a cable connection 28 to the impulse dubbing device 30 manufactured. Via this cable, the frame pulse series 29 of the two Pulse tracks (e.g. 10, 11) brought to the pulse dubbing device 30 a pulse cable 31, via which the projector control pulses 34 to the stereo pulse head 32. Of the recording device 25 are performed. The start / stop remote control is via a further cable 33 of the recording device 25 or in the scene-wise asynchronous image-precise dubbing possibly also the transfer device 24 operated.

As can be seen from FIG. 7, the impulse dubbing device includes 30 several twofold preselectable forward / backward decades 35. Two provided in the device LF amplifiers 36 are integrated in the pulse dubbing device that the program selector switch 37 the frame pulses 7 of the respective track to the up and down counter 35 reach.

The position a of the program selector switch 37 ensures a scene-wise Asynchronous dubbing. The frame pulses of the upper pulse track 23 arrive at a via the program selector switch 37 on the preselectable up and down counter 35. To the frequency divider 38 and / or tone generator 39 and thus to the output of the device With this program, impulses 7 arrive when the first preselection is made via the switch 40 a pulse from the "signaling" block 41 the delayed flip-flop 43 with the Relay 44 has switched, thereby the switch 45 through the program selector switch 37 was switched over and also the program relay 46 through the start / stop cable 33 is switched via the socket 47. The recording device 25 is started automatically, after the delay stage 48 by the same pulse of the signaling 41 was switched with the relay 49.

The signaling pulse 41 of the arrives via the contact 46/2 first preselection 40 is also saved to the scene counter 50 by adding the status of the soundtrack and is displayed. The scene counter 50, which is also required for other purposes, consists of normal forward decades. Preselection switches 40, 51 are not used for this purpose needed.

After the count of the up / down counter 35 of the number of corresponds to the second preselection 51, the signaling 42 switches this preselection Relays 44 and 49 return to their initial position after the respective delay time has elapsed return. This causes the pulse flow of the frame pulses 7 to be sent to the tone generator 39 and thus interrupted to the output of the device. The same becomes the recording device 25 stopped. All other pulses entering the pulse dubbing device 30, FIG. 7 7 are thereby kept away from the tone generator 39 and / or from the frequency divider 38. (For the standard sound system frequency divider 4: 1). Odd of four remain behind End of scene in frequency divider 38 sp-.tcihCrt, which means that for the next scene the Pulse spacing 7 b is retained, since the further pulse flow to the frequency divider 38 is released only after the signaling 41 has emitted a new pulse.

The delay times of the two delayed trigger stages 43 and 48 are dependent on the start / stop delays of the recording device 25 used. If a recording device has a delay of the mit n when starting, this is delayed flip-flop tape recorder 48 to minimally the delayed flip-flop pulses 43 to match the tent n plus delay time minimal. Through this comparison is the impulse dubbing device Fig. 7 on the recording device 25 with the delay time n fixed o Depending on the film frame rate and the delay time of the automatic start / stop of the recording device 25 must accordingly a lot of impetus before sound event to be transferred are available. With the delayed flip-flop Tape recorder 48 is the exact distance between the last pulse 7 of a scene and the first impulse 7 of a new sound scene, which also shows that the adjustment of the delayed flip-flops correspond to integer frame rates. The delayed flip-flops 43 and 48 are to be designed in such a way that, if necessary, start / stop for tape different delay times can be output.

At position b of program selection 37 synchronous scoring track 22 are instead of the asynchronous delay time pulses to be made available accordingly to cut a lot of film frames, which has to be taken into account when recording films so the necessary yfmpultsè are created. With tape recorders 24, 25 of today's design Delay times of up to approx. 100 ms are common. This means that a maximum of 2 film frames to be cut.

The switch is in this position b of program selection 37 45 again in the position shown in FIG. Apart from the fact that the flow of momentum reaches the up / down counter 35 via b, it remains for the rest of the position a also obtained for b.

As soon as the tape start / stop cable 33 from the socket 47 according to FIG 7 is removed, the playback dubbing goes via position b of program selection 37. The program relay 46 has thus dropped out, the contacts 46/1 -46/4 are here in the position shown in FIG.

As a result, the impulses of the upper track 10 reach the scene and pulse counter 50, the pulses of the lower track 11 on the up / down counter 35.

Depending on whether the first series of impulses is added to the playback setting the upper or lower track is recorded, relays 44 and 49 must be in front Start of scoring switched on or de-energized. The lamps 52 and 53 signal the content of the delayed flip-flops. So between scene-wise and playback scoring the pulse dubbing device Fig. 7 does not have to be adjusted again, the pulse flow to the frequency divider 38 and tone generator 39 during playback dubbing via contacts of relay 49 out. This assumes that the minimum delay time of the delayed flip-flop 48 "tape recorder" C is half the frame rate. From this So far it follows that the size of the switching delays in the tape recorders 25 was compensated with these measures. Incidentally, the delay times are of the tape recorders 25 is only important for the scene-by-scene setting, since it is the playback setting Fig. 1 and 2 is a non-stop setting. The preset counters 40 and 51 of the impulse dubbing device are again according to the circumstances after each sound scene the next scene. The pulse flow to the tone generator 39 is at this Type of setting without interruption, as the flow of impulses alternates from the upper or lower pulse track of the dubbing device 24 is fed. With the one shown in FIG Switches 54 and 55 are the counters to zero after the end of each sound scene to put.

Instead of the previously mentioned preselection switches 40 and 51, a electronic storage can be used. In this would be the characteristics of each Scene of a film entered. The dubbing would be done using an electronic Storage takes place fully automatically.

From the pulse generator 56 after switching on the switch 57 the pulses via c of the program selection 37 to the up / down counter 35. After this the counter reading and the reading of the area codes 40 and 51 coincide, will the relays 44 and 49 switched over ^ i. As already described, this creates the recording device 25 started or stopped and the pulse flow to the frequency divider via contact 44/1 38 and / or released or blocked to the tone generator 39. So depending on your position the switch 58 asynchronous LF pulses in a preselected number to the sound carrier of the Recording device 25 are fed to the upper or lower pulse track. Intended to If the pulse frequency is output 1: 1, switch 59 must be operated. In 7, the pulses 7 via the frequency divider 38 are four : one squat. With the switch 60, the divider 38 is brought to zero, what is required before the start of scoring.

Has to interrupt the scene-wise setting of a film for some reason the contents of the memory can be accessed via switch 61 and position f of program selection 37 of the frequency divider 38 can be determined. When the setting is continued, the To set frequency divider according to the previously determined memory content 38. The lamp 62 serves to identify the memory contents 38. When the lamp lights up 62 is reached zero position, which also means that the next incoming Impulse 7 is fed to the sound carrier of the recording device 25 via the sound generator 39 will.

The overlapped individual image pulses can be accessed via the position e of the program selection 37 are counted according to Fig. 1.

After this information, the twice rotated film images can be made one or the other scene can be cut. Via position e of the program selection 37 can furthermore be provided by a suitable contactor, e.g.

a light barrier, the individual images of a film or a film scene to be counted.

The lZor / Rückwäntsdekaden 35 are necessary for counting the film frames, since it is not always ensured that e.g. a motion picture viewer is frame-accurate stopped can be. If the film is pulled through too far, the forward / reverse switch 63 is opened reversed and the film slowly turned back. The one when counting the film frames The information gathered is used for later film editing and also for setting the preselection switches 40 and 51 for sound editing.

Via the relay 64 and the associated contact 64/1 can outside the film dubbing with the help of a timer via the position e of the program selection 37 pre-selectable actions can be triggered (alb. Time-lapse recordings with a film camera). With a pulse output of the timer of one pulse / min. leaves the time between two switching processes can be extended to about a week.

By switching the switch 54 brings the predetermined time Sequence via the signaling 42 always automatically returns to the starting position.

The relay 64 only works when the switch 65 is closed. With the switch 66 the delayed flip-flops 43 and 48 are brought to the zero position, the lamps 52 and 53 being energized.

From Figure 8 it can be seen that the stored on the tape 7 pulses of each pulse track brought to the level via a preamplifier stage 67 which is required for the further processing of the pulses 7.

The switches coming from the camera's tone generator pass through the switch 68 Impulse 7 either on the upper or lower impulse track of the sound carrier. About a further toggle switches 69 to be actuated by the same key are activated by the possibly Track already occupied with pulses 7, these pulses 7 passed to the NAND element 70. The FF 71 connected downstream of the NAND element 70 is in the idle state via the camera trigger 72 in mass. Incoming impulses from the tape can only switch the FF 71 when the camera shutter button 72 has been pressed.

After the end of a full or partial pulse 7, the FF 71 is switched over, whereby the one input to the NAND gate 73 is switched to H potential. Through this it is ensured that the subsequent monostable trigger stage 75 via the NAND element 74 only whole pulses delayed. After the set delay time has elapsed, it switches the FF 76 and switches a relay 78 via a transistor 77. Via the relay contact 78/1 the camera motor M is supplied with power. By this circuit arrangement it is ensured that in the playback sound film recording Fig. 1 the pulse overlap 3.6 are recorded congruently. After the end of a sound film recording the FF 71 and 76 are connected to ground again via the camera trigger 72. Through this the circuit Fig. 8 goes back to its starting position.

The first playback scene is to be filmed with switch 79 pressed, since at this point in time no pulses 7 are available that were previously cause the circuit described to tip over. This device is also used for the scene-wise film recording Fig. 4, the switch 79 is also to be operated.

The NAND elements 80 and 81 connected downstream of the amplifier stages 67 control indicator lights that provide information about which part of a Playback preserve Fig. 1 and 2 has already been filmed. Through this visualization of the impulses 7 does not need the playback recording Fig. 1 in the order of the current one Scene numbers to be filmed. This has the advantage that when shooting films that require different recording locations that are necessary for the respective film recording location Scenes can be recorded in any order.

At the output of the amplifier stages 67, the pulse sounding device 30 Fig. 7 the pulses 7 of the respective pulse track are counted. About the Nand link 82, the film frames to be cut in areas 3, 6, etc., are shown in FIG. 1 as two of the Playback scoring determined.

If this additional device is also used for film dubbing, the LF amplifier and rectifier stages provided in the pulse dubbing device 30 Fig. 7 36 are omitted since these are provided by the preamplifier and rectifier stages 67, FIG. 8 can be replaced.

In the mixed setting, i.e. the scene-wise fig. 4 and the Playback dubbing Figs. 1 and 2 in a movie, the playback area is closed first set to music, the impulses 7 being played to the recording device 25 here one: one will. The playback area pre-dubbed in this way is used during the actual dubbing how the scene-wise setting is treated.

Although the distance between sound head 1 and pulse head 2 is not bound to any measure is, when setting a film to music in mixed technology, the distance between the two must be Heads 1 and 2 in the dubbing device 24 must be the same as that of the recording device 25.

Only if the number of dramaturgical and / or film-technical Reasons to cut film frames is smaller than the integer self-delay incl.

Delay of the flip-flops of the recording device 25 corresponds to is the number of film frames to be cut equals this integer delay. Is the number of film frames to be cut for each scene greater than the number of integers? Corresponds to self-delay, then is the integer self-delay in the setting of the area codes 40, 51 to be taken into account. This also means that only the out For dramaturgical and film-technical reasons cut film frames to be cut Need to become.
