Digitalization and networking is the hot topic of today's technological advances, video and audio technology is also inseparable from the tide of technological progress. Drama Centre as digital audio production and nonlinear editing transition has been completed many years ago quietly. Although quietly, but brought us the digital high-quality, high stability of image and sound, non-linear editing provides an extremely convenient for our production methods, all this makes us a lot. Quietly reason is because the transition to a very smooth transition, but from single to single, the original little change in the production process.
Today, the drama centers of video post-production system has completed a new transformation?? Network production. In fact, in video technologies, networking and digital, as has been nothing new, television program production using the network is already very common application. Then, show the need for central network construction and features is it?
1, production and demand is the driving force behind technology development With the TV in the TV screen
advocacy role in continuous improvement, leadership and TV more and more the importance of various related industries, this change in emphasis will naturally be reflected in the middle of the production process, the most prominent impact is backward links of the trial tablets, and more. After the move is off from the last review to review the compiled version of the tape delayed synthesis of the master tape, in which one of the reasons is because the plot elements of the trial tablet integrity of staff put forward higher requirements, such as read story on the need to facilitate have a clear dialogue, in order to understand the rhythm and emotional drama, music and effects but also the background, required more trial version to see more close to the broadcast and accomplish the more the production process, which is the trial version to see backward. Increase is the increase in the number of the review. Shift and increased after the superposition result, the trial to see the increase in the number of lead changes version number increase, the latter version of the amendments are moved to re-create some of the changes, and once again generate new tape, the master changes to the master often is a direct copy tape linear editing, so that the rhythm of the plot, the overall structure of the same duration of each episode so very difficult to control, many changes culminating in the final before the passage of the mother may want to keep several sets of version of the tape. Again, a cycle of film production is limited, the more often the more tension to the end. Stand-alone mode in the original, although the same can be more work, but there rush to use material, the content-packing, no adjustment system, multiple occupation and so on.
Appeared in more than sets of tapes and modify difficult problem is that the resulting change in the form of production, while the original stand-alone mode of operation has been unable to adapt to such changes, in order to solve production problems, so we need to network construction.
Second, technological progress is an effective way to improve production capacity
Network environment and the technical structure of single mode There are two main differences is the first network has a large centralized storage area, the equivalent of each terminal can be seen a huge storage space, which is to do single not, of course, not all terminals can also have this space, there is no need, we just need to be dynamically allocated according to the production on it; second point is that all terminals are associated in a network environment, according to the needs of Several terminals can simultaneously on the same space and the content of which many, in that more jobs can be done to work.
Large storage space to allow us to edit uncompressed master all remain on the network hard drive, but did not work as stand-alone must save the output to tape, this version solve the multi-master key to the problem. In the network, we have also installed a terminal to watch the trial between the trial to see the network link into the production environment, regardless of the number of trial to see and modify, just want to modify the part about re-editing, you can immediately generate a new version. Several versions of changes to the network only in the more sets of editing the list, the space it occupied is negligible. If you modify the synthesis of the master, the corresponding sound may need to be re-produced. As the drama center with audio and video departments do not, it is not to create, we added in the video network, an audio production of the terminal. Problems encountered by the sound changes, you can edit the data and sub audio track data transfers with the activities of the hard disk to install to the network, although the terminal in the audio production and audio synthesis engine room monitoring conditions are different, but you can edit the data with a transplant in full accordance with the audio synthesis engine room of the mixing ratio of the modified part of the re-synthesis. Final adoption of any changes to be completed until after that we need the output from the network master tape recording of a synthetic. This, we have fully resolved a stand-alone mode, caused by changes to retain as many version of the tape issue, not only that, the network environment has greatly improved the flexibility of modification, the modification of work into the normal editing links among allow the crew to film and modify the trial as a burden, improve the work of the enthusiasm and efficiency.
