Digital has become a very familiar term for people. Digital technology and digital products enable people to enjoy more and more conveniences. It is also becoming a part of our lives. With the travel and people's improvement of cultural life, the camera began to enter the family and became one of the supplies for travel and home life. Your own wonderful moments can be remembered forever, time can go back, and history will not be forgotten. The rapid development of computer technology and the establishment of digital video compression standards have made computer-based nonlinear editing more and more popular, and it is time to establish your own nonlinear editing studio. With a non-linear editing studio, you can develop your own creativity, have your own small world, develop your personal skills, and earn extra money to experience another digital life.
1. Equipment
1. The concept of non-linear editing
Non-linear editing is compared with the traditional linear editing in chronological order. Traditional linear video editing is based on the information recording sequence, and the video data is played back from the tape for editing. It requires more external equipment, such as video players, video recorders, and special effects. Generator, subtitle machine, the work flow is very complicated. Non-linear editing is done digitally with the help of a computer. Almost all the work is done in the computer. There is no need for so many external devices, and the call to the material is also realized instantly. There is no need to repeatedly search on the tape, breaking a single time Sequential editing restrictions, can be arranged in various orders, has the characteristics of quick and easy, random. As long as the non-linear editing is uploaded once, you can "do whatever you want" until you are satisfied, no matter how many times you edit, the signal quality will never be lower, so you save equipment, manpower, and increase efficiency.
2. Computer
The general requirements of non-linear editing computers are relatively high. The key components used are CPU, memory, hard disk, motherboard, and graphics card. In principle, the CPU is P4, and the general configuration is now P4 3.06GHz; the memory uses 512MB DDR400, preferably two; the motherboard uses ASUS i865 or i875 chip motherboard; the hard disk is preferably 7200 rpm, the capacity is 120GB, and it is best Two, one for the system and one for the video material, can use SCSI for more professional; the monitor can use two 17-inch, if the place is small, use a 19-inch monitor, the price of a 19-inch and There is not much difference between the two 17-inch monitors. The graphics card and sound card should be determined by the non-linear editing card. Some non-linear editing cards have compatibility requirements for the graphics card and sound card. It is important to choose a large internal space, so that the accessories will not be too crowded, which is conducive to heat dissipation. Second, pay attention to heat dissipation. It is best to have a convection fan (one induced air and one supply air). If you are a large user, if you run for a long time, a stable high-power power supply is indispensable. In principle, you must choose a 400W server power supply. The chassis can also choose a server type.
3. Non-linear editing card
There are only a few foreign large companies producing non-linear editing products on the market, and there are not many brands. Everyone is familiar with Pinnacle, Maichuang and Kang Nengpu, etc. The use is roughly divided into three grades, household grade , Professional grade, broadcast grade, the price difference is relatively large.
Household-grade products range from several hundred yuan to several thousand yuan. The editing function is simple. Generally, it is not real-time editing. The speed is slow. Special effects need to be generated. The most common is DV1394.
The price of professional-grade non-linear editing cards is between 5,000 and 10,000 yuan. It can be edited in real time without the need to generate special effects. The function is relatively powerful. After editing, the output is burned into VCD and DVD, and the playback effect is also satisfactory. Almost all non-linear editing cards at the price of 8,000 yuan can collect and compress MPEG-1 (VCD) and MPEG-2 (DVD) in real time, and support real-time output of DV and analog ports.
As for the broadcast-level non-linear editing card, it is absolutely superior in terms of editing, subtitles, functions, and effects, but the price is also staggering, only used by TV stations and advertising companies.
Establish a personal non-linear editing studio. It is recommended to use a professional-grade non-linear editing card with a hardware compression function at around 8,000 yuan, which is helpful to quickly complete some video processing tasks with low editing requirements.
2. Work
1. Collection
The current non-linear editing card can recognize both digital and analog signals. The quality of digital signals is better than analog signals. DV signals are collected by IEEE1394 interface into AVI format for data transmission. Lossless editing is possible. On the interface, the highest video quality is DV, The second is S-Video, and the second is AV. When collecting, choose a high-quality interface for signal transmission.
2. Edit
On the basis of good resources, the artistic level of a film depends on your editing level. The editor must first look at the content. Before filming, first understand the summary of the content. Strings are shot like a story. There are storylines and conflicts. The focus is on resolving conflicts and conflicts, so that the film has a cultural charm. The second is the technique. Proficiency in editing software, use of special effects, superposition of filters, subtitles, enhancement of theme content, screen language, multi-angle shooting to enhance visual impact, etc. To dare to innovate, it is the most creative to watch movies and advertisements on TV regularly. At the same time, it is necessary to abandon a psychological misunderstanding. Some people think that with a professional non-linear editing card, you can make a very good movie. In fact, the tool is only a necessary condition for working, and the editing process is also the same.
3. Output
In order to finally let everyone share the joy of labor achievements, packaging and generating a complete program that can be played on other media is the last process of nonlinear editing. The choice of storage media is generally more magnetic tape or optical disk, hard disk is rarely selected. From the perspective of storage and communication convenience, the advantages of optical discs are more obvious. There are certain conditions for tape storage, such as anti-magnetic and moisture-proof. The storage time is about 5 to 10 years. The choice of storage format, AVI format, MPEG-1, MPEG-2, etc. are often used. In terms of effect, the AVI format is the best, but the file is very large, and other formats are lossy compressed storage.
3. Burning
1. Selection of DVD and VCD
China is not only a big producer of VCD players, but also a big consumer. The prosperity of VCD players has caught the eyes of many large foreign companies, as is DVD. I believe that with the advancement of technology and the reduction of prices, the days when DVDs will replace VCDs will not be far away. The professional-level non-linear editing card should of course choose the output and burning of the DVD format. The capacity of a DVD burning disc is 4.7GB, the VCD is only 650MB, the resolution is 240 lines for VCD, the DVD is more than 500 lines, and the DVD player The price difference with the VCD player is not very big, people are more willing to choose the DVD player.
2. Burning format
DVD-RAW, DVD-R (W), DVD + R (W), the latter two formats are relatively popular, also called "+", "-", so there are also "-", "+" formats Burner and burner. The playback effect of these two formats is similar, and can be recognized by home DVD players.
The "-" format is mainly represented by the Japanese Pioneer Company, and it was also the earliest development and introduction. The "+" format was later proposed by companies such as Hewlett-Packard and Philips. In terms of speed and convenience, the "+" format is slightly better. The software giant Microsoft also announced support for the "+" format, so some people think that the "+" format may win. Burning discs in the "-" format on the market are cheaper, but DVD burning discs in the "+" format are not common.
In addition, the market for DVD recorders is currently unknown, and even Sony, which supports the "+" format, has not dared to act rashly. The Sony-500AX, which is launched for all burned discs, is expected to be clear by the end of this year.
3. Burner and burning software
As mentioned earlier, the format problem determines the DVD burner. The burner generally sends burning software. From the perspective of safety and stability, the random software is more reliable and there will be no problems. You can select several brands to burn the disc for trial, and it will always be used as long as the compatibility is good, without frequent replacement.
4: Software application
In addition, just briefly mention the application of editing software. Non-linear editing software is actually a "Premiere", a professional video editing software, even used by American film companies.
The second is the editing software of various non-linear editing card manufacturers. VideoStudio is also a very useful video editing software.
I think the first choice is the non-linear editing card random editing software, followed by the application of "Premiere". If you want to do creative work, you should also learn to use "3DMAX" and "Photoshop", master the knowledge of fine arts and painting, have the correct market positioning and rich cultural connotation, reflect the artistry and characteristics of your digital studio.
