A great deal of editing and splicing is done. It's not unusual to run 20 splices in a half hour show. The Christmas color special, for example, included 50 splices. All of these are made with the regular RCA TV Tape splicer but with a KSTP-designed mounting bracket for "sit-down" use. KSTP has proved the efficiency of installing more than one machine, since with two, one can run tape shows back-to-back. They can also insert commercials and other small pieces into programs without having to edit the master tape. It has been found very convenient as well as economical to use separate small reels for individual commercials and announcements rather than edit them in and out of show tapes. (Webmaster note: RCA's rival, Ampex, claimed the rights to the name "Video Tape," hence RCA's use of the name "TV Tape." However RCA used the Ampex 2" quadruplex recording format and the recordings from both manufacturers were compatible). |

Dick Elliot at the "sit down" splicer position designed by KSTP staff. This features a special mounting bracket that makes splicing easier. (Webmaster's note: before the advent of electronic editing, early videotape was literally spliced, but since the video image is not visible on the strip of tape, a cumbersome process of finding the electronic frame line using a special magnetic fluid and viewing and cutting under a microscope was used. |
KSTP has three TRT-1B Color TV Tape Recorders. Note exhaust ducts at top. (Webmaster's note...the TRT-1B requires 3 racks: 1 for the tape transport, and 2 additional racks for video and waveform monitors and Recorder tubes and electronics. |

Two complete film islands are installed at KSTP. One is completely monochrome, while the other can be both color and monochrome. Each is equipped with two 16mm sound-on-fim (S.O.F.) projectors and 2 by 2 slide projectors. |

(Webmaster's note: In KSTP's simple kinescope film recording setup, the video monitor being filmed is not underscanned, virtually assuring that vital picture area is being cropped out to avoid seeing the physical edges of the televison screen. This practice was unfortunately quite common in the days before TV Tape, when the only way to preserve a television image was to film it off a TV screen. Kinescope recordings are vastly inferior to TV Tape which revolutionized TV broadcasting. Unfortunately, the "convenience" of re-recording virtually destroyed many now-historic television broadcasts when tapes were "degaussed" and reused. Non-eraseable film kinescopes are the only surviving recordings of many late 1940's-1960's television broadcasts.
Kinescope film recordings improved in the 1960's, but since TV Tape (or Video Tape) was becoming increasingly more popular, knescope film recording was destined to be obsolete. RCA was still innovating improvements in kinescope recording in the early 1960's. See the RCA's TFR-1 Film Recorder introduced at the 1962 National Association of Broadcasters (NAB) convention. |

KSTP-TV's complete color facilities for live, tape, and film telecasts are among the finest of any station in the nation. In all ways KSTP is endeavoring to fulfill its pledge to serve the public interest. This mark of pioneering spirit is further evident in the switch to color, making KSTP-TV the first station in its Northwest area to offer the finest in television fare to its advertisers and its audiences.to its advertisers and its audiences. | ||
