Hope Small Orchestra Running DV

In recent years, a person interested in editing video on a personal computer has been hit by a real avalanche of information. But more recently, it was collected bit by bit and many technologies, including the simplest ones, had to be mastered blindly. But in the world of information technology, things are changing very quickly. Opportunities previously unavailable to the ordinary user and information about them are available to everyone today. Almost everyone who owns a personal computer (PC) and video camera can try their hand at video production (even in creating the simplest home movie). Depending on the intentions, it may take either a little if the end result is a movie for a home video archive, or a lot if the intent is to create the movie “Jurassic Park 4”. We’ll talk about this.

Who are we?
The audience of people involved in video production on a PC is diverse.

Some come to this fascinating world from the professional environment of video producers, who yesterday smiled at the word “multimedia”. And this is natural, because then the word “multimedia” was more associated with the presence in the PC of a sound card and the roar of dying monsters in the game DOOM. But today even the most unrealizable desires of amateurs and professionals are sometimes justified. Although there are still skeptics who trust exclusively in traditional ways of editing video or cinema. They are not at all impressed with the progress in information technology (IT). And you can’t lure them into a keyboard for any persuasion. The level of professionalism of many of them allows you to make masterpieces on the assembly tables of the dawn of television or cinema. But this is the exception rather than the rule.

Others are people who have come to video production on a PC from computer scientists. Most of them are experienced users and programmers. Including the “specialists” of multimedia, which has grown to professional video. Many of them are simply brilliant, but most of them sometimes lack knowledge of the laws of editing and the basics of directing.

Well, the third, probably the largest group, are readers – dreamers. Connoisseurs of all news and new products. Patient fundraisers for their own video camera and PC with a mounting card. In the end, they succeed. But often after this, doubts and questions inevitably arise – is the solution too expensive purchased to solve rather modest tasks? Or, on the other hand: will the acquired cheap board allow to realize all grandiose plans?

The correct answer must be found before buying, carefully analyzing the market in which you will have to work and the complexity of creative tasks. It is especially important to know the history of the issue and the main development trends.

Better than the 500th, but not the 600th
About 10 years ago, the director producing a television product in a traditional linear way considered the presence of the so-called 500th console, Sony DFS-500., At that time one of the most popular among professionals, mandatory.

This miracle of television technology made it possible to produce very fashionable effects at that time, such as, for example, a “page” or a “slide”. Apply various filters to the video, such as ripples on the water and others. Mix titles from the character generator and many other things pleasant and useful in the video economy to the video signal.

The 500th was surrounded by supply tape recorders, an editor controller, an audio mixing console, a character generator for titer printing (overlays on graphic images, titles) and a recorder – a tape recorder recording the resulting signal. Naturally audio and video monitors. All this together was called a linear editing complex, ideal for producing news releases or stories. Such a complex did an excellent job, and is still coping with small and uncomplicated, in terms of effects, tasks. But if there is a need for complex multi-layer special effects, for example, in a multi-screen (at the same time placing several dynamic pictures on the screen), then the capabilities of the remote control are no longer enough. For such an installation, it was required to have several video tapes on hand in order to sequentially lay down video layers from tape to tape – picture by picture. This procedure is linear, time-consuming and time-consuming. It should be borne in mind that each dubbing naturally degraded the quality of the original video material. Despite the fact that the latest digital solutions have improved the linear editing technology, in general this does not solve the problem of producing complex multi-layer effects, which are vital in the production of, for example, commercials, music videos, and educational films.
