Introduction

Videoflight, Inc., a wholly owned subsidiary of Sony Corporation of America, was founded in 1964. It was established to augment the sale of video tape recorders by the Industrial Products Division of Sony Corporation of America. Its primary business at the outset was to transfer first run films to Sony video tape for use by the airlines in Sony airborne entertainment systems. Within one year it grew from an initially simple installation to that shown in the photograph on page 2. It is probably today the largest film-to-tape transfer center in the world.

Videoflight operates 24 hours a day, 6 days a week and produces a large quantity of high quality 2-hour and 4-hour tapes a month.

Over the past two years the tape production techniques and the facilities for producing them have significantly improved through constant study, research and capital investment in the latest tape producing equipment.

The story of Videoflight is the story of a pioneering organization. In 1964 when Sony first began airborne entertainment systems' development in conjunction with American Airlines and Pan Am, it became apparent that to assure the best possible performance of the entertainment systems, it would be necessary to ensure that the video tapes used were of the highest possible quality. It was necessary that this quality be realized on anyone of some 150 video tape recorders with any tape. "Interchangeability," as this characteristic is known, had never before been achieved to this degree and there were many who thought it was impossible. Sony realized that to achieve its high standards for tapes it would have to establish a new facility devoted entirely to tape production. For this purpose it invested a substantial amount in facilities and necessary supplies at Videoflight and hired highly skilled broadcast video engineers with extensive experience in video and audio (picture and sound) recording to man the new facility.

For over two years these men and this equipment have turned out thousands of quality tapes each month from either films or other tapes while, simultaneously, continuously upgrading operating procedures and operating equipment until, today, Videoflight has achieved an unequalled and enviable position in the field of multiple video tape production.

 

Tape Duplication

The management of Videoflight recognizes that there is now developing a vast demand for multiple copies of tape in such fields as medical education, sales training, cable television, industrial communication, home entertainment and general education. To meet this demand Videoflight has recently added equipment to permit the production of video tapes in any configuration and to any standard. For example, multiple tapes may now be made for the Sony EV-200, industrial Videocorder, the Sony CV-2000 series Home Videocorders, in addition to the Sony PV-120A, PV-120Al, PV-120U and video tape recorders of other manufacture.

Special Requirements Where the source material is film and it is available to Videoflight for a very limited time (as happens with pre-release films) Videoflight combines the capabilities of its film chains and Allenized broadcast VTR to make master video tapes from which multiple copies may be made in the appropriate configuration (that is, 1/2, 1 or 2 inch video tape.)

Videoflight has acquired extensive experience in making tapes from Cinemascope-type films. The necessary change in aspect ratio is achieved by skilled operation of the electronic

controls in theVideoflight system while following the script from which the film was made. The essential portions of each scene are recorded for later reproduction.

The Videoflight color film chain provides red, blue and green color output signals which may be encoded appropriately to permit recording on video tape.

For example, excellent line sequential color recordings have been made at Videoflight on the Sony PV-series Videocorders. SECAM and other recording systems may also be used.

 

Production Procedures

Incoming Inspection

When source material is received by Videoflight, it is fully logged and passed to incoming inspection. The optical condition of the material (if it is film) or the magnetic condition of the source material (if it is tape) is determined prior to recording. If the material is technically inadequate for the making of a quality recording, the customer is advised and substitute material or an alternate approach is determined.

Source Equipment

When the source material is adequate technically, it is loaded on the appropriate source equipment-35mm film chain, 16mm film chain, 35mm color film chain, quadruplex video tape recorder or other-sound and picture levels are established and the source material is run with constant surveillance of both sound and picture levels by skilled operators as well as by automatic level-control electronic equipment.

Playback and Quality Control

When the recording is completed it is played back on the recording machine, as well as on other similar machines to assure good audio and video quality and interchangeability. If anyone of these elements falls below professional standards or if any other defect appears (such as tape drop-out), the tape is rejected by the operator and a complete re-run is performed. If the tape reaches the established quality. standard as far as the operator is concerned, it is passed on to the Quality Control Department where it is again put through rigorous tests.

If it passes those tests it goes to the Shipping Department where its serial number, the addresses and the subject matter are noted. Logging of the total number of transfers made, whether shipped or not, and their dispositions are made accurately so that copyright owners can be assured that no unauthorized showings of the source material will be made.

Re-Use of Tapes

When tapes are returned for re-use, they are inspected for wrinkles or other defects, spliced if necessary, and bulk-erased before transferring new programs to them. Accurate records of tape erasures are also kept.

 

Rates

Videoflight know-how and capability are now being made available to the industrial, medical, educational and entertainment fields at very modest charges. A comparison of the charges with those of conventional video "dubbing" studios, will indicate that they are lower. Such economies are possible because of the volume of business which Videoflight does in the airlines field. ,

Rates are available on request.

The Aiborne VTR

Sony was the first Japanese company to produce an Ampex-type VTR. Ibuka, who believed that Sony's calling was making products for home use, however, was not satisfied with the distinction. He thus directed Kihara and his video development staff to research the use of transistors to create a more compact VTR. In November 1959, they succeeded in producing the first transistorized Ampex-style VTR, which was a big step toward a smaller VTR.

Then in 1960 Sony and Ampex agreed to share their VTR know-how. Ampex was anxious to gain Sony's knowledge in transistor application technology. Sony, on the other hand, could learn about VTR technology from Ampex. Masahiko Morizono, who had worked on audio equipment at the Sony audio factory in Haneda, was enlisted to help in this joint effort.

Unfortunately, this project did not last long. There were limits to the Ampex 4-head VTR. When any of the rotary heads became work, it was necessary to replace all of them, which was a major expense. Kihara's staff developed a 2-head transistorized VTR in which the individual heads could easily be replaced.

After research and testing a total of five trial models using Ampex and Sony VTRs, the end product was the world's first transistorized VTR, the SV-201. This 2-head, helical scan type VTR with a tape speed of seven inches/second (the same speed as an audio tape recorder) had much better performance characteristics than any other VTR in the market. Unfortunately, however, it was neither suited for broadcasting nor home-use. With just 2 heads, the broadcasting companies were not interested. It was also too large and expensive for the average consumer. Sony decided to develop different products for different markets. The result was Sony's PV-100. At approximately one fiftieth the size of broadcast VTRs, it was considered pictportable,pictand represented a revolutionary breakthrough in miniaturization.

Sony announced the PV-100 in September 1962. Less than a year later, sales of the 2.48 million yen set began first in Japan, followed by export sales to the United States. The PV-100 was intended for business-use ie., industrial, educational, and medical applications. Sony salespeople went from hospitals to schools and airline companies selling the VTRs.

At the time, most airlines used 8mm and 16mm films for their in-flight movies. Flight attendants, however, found the film difficult to handle. It often rolled off the reels or ripped. The short screening time also made the whole process even more troublesome. Thus, the airlines were very interested in Sony's suggestion of using VTRs instead.

In 1964 and 1965, VTRs were introduced on American Airlines and Pan American flights. Sony's job was to provide the pictsoftware.pict In order to deliver new tapes to the airlines on a weekly basis, Sony established the pictIn-flight VTR Service,pict a VTR duplicating factory in the suburbs of New York. This was seen as a sure money-making venture.

However, flight attendants seemingly did not treat tapes with much care. Flight attendants would jam the open-reel tapes while threading them or leave them near the beverage trays, where inevitably coffee would spill over them. The original estimate that the tapes could be used at least forty times was completely off target. Most tapes came back in pitiful condition after just one use.

Despite these troubles, Sony was relieved that the VTR, which was originally considered marketable only to broadcasting companies, had come one step closer to consumers. In addition, the basic technology behind this VTR developed by Nobutoshi Kihara and Masahiko Morizono was passed on to the 1-inch Omega VTRs and half-inch Betamax VTRs
