1, Digital Fusion /Maya Fusion: Digital Fusion is a professional composition software based on PC platform developed by Canada Eyeon Company. When AliasWavefront launched the famous 3D animation software Maya on the PC platform, it did not transplant its own Composer synthesis software to the PC at the same time. Instead, we choose to cooperate with Eyeon and use digital fusion as the synthesis software to match Maya, which is called Maya Fusion. This software is one of the best comprehensive software on PC platform at present. Joining hands with Maya is even more powerful. It adopts a process-oriented operation mode, and provides professional tools such as color comparison, keying, tracking, channel processing, etc. It also has functions such as 16-bit color depth, color lookup table, field processing, film grain matching, network generation and so on, which are generally only provided by large professional software. In addition, the function of manual baffle is also very unique and powerful. Through the unique additional channel function, it can work closely with 3D software such as Maya to modify the materials, textures, lighting and other properties of 3D objects in 2D environment. Maya Fusion does not specify the resolution of materials, and users can process images of any resolution and combine them together. This means that Maya Fusion can serve a variety of synthesis tasks, from low-resolution multimedia and video programs to movie stunts. At present, in Hollywood, which has always praised SGI platform and Inferno and other large-scale software, Maya Fusion has also occupied a place, and has undertaken the synthesis task in a large number of stunt films such as Dr. Oolong, Elven Mouse, Storm of the Century, Extreme Cold and so on. In terms of TV programs, Maya integration is more like a duck to water. Many small and medium-sized production organizations in North America have begun to use Maya Fusion as their main synthesis software, and many large-scale production organizations also use Maya Fusion as a supplement to large-scale software. Digital Fusion3.0 released at NAB 2000 conference is the latest version of this software. In this version, a vector-based drawing tool is provided, which greatly improves its original drawing function and greatly improves the efficiency of this software. The emergence of the new version further consolidated the position of Maya Fusion. Note: The latest version is Digital Fusion 4.03b

2.Infino */Flame */Flint *: Discreet Logic of Canada has always been a leader in the digital synthesis software industry, and its main products are Infino */Flame */Flint * software series running on SGI platform. These three kinds of software are high, medium and low-grade products of this series. Infirno * * runs on the multi-CPU super graphics workstation Onyx, which can not only produce 35mm movie stunts, but also meet various programming requirements from HDTV to ordinary video. Flame* * can run on multiple workstations, such as Octane, O2, Impact, etc. , mainly used in the production of TV programs. This software is widely distributed in large and small advertising production companies in Beijing, and it is the main force of domestic TV advertising production at present. Although these three softwares are quite different in scale, supporting hardware and processing capacity, the functions they provide are quite similar. They all have very powerful synthesis function, perfect drawing function and certain nonlinear editing function. In the aspect of synthesis, they provide a layer-oriented synthesis method with the action function as the core, so that users can manipulate the picture of each layer in the real three-dimensional space. From the action module, you can call a lot of composite special effects such as color contrast, keying, tracking, stabilization and deformation, which is very convenient and fast. Users can also call in 3D modeling files, or make 3D subtitles, and map textures for them in the action module to make them move. Action also allows users to set various lights. In the high-end system, with the hardware support of SGI workstation, the composite picture can be played back in real time. In the new versions of Inferno 3.0, Flame 6.0 and Flint 6.0, a brand-new modular keying tool is provided, which can achieve excellent keying effect for complex keying situations and realize semi-automatic manual blocking function. By using their drawing module, users can freely define brushes, decorate, copy and polish pictures conveniently, and make animation effects on strokes. Although their nonlinear editing function is relatively weak, they are more than enough for making advertisements, titles, MTV and other short programs and special effects shots of independent films. In addition to this series, Discreet Logic also provides Fire/Storm series nonlinear editing software based on SGI workstation. The editing function of these two softwares is quite powerful enough to be competent for a long program production task, and the synthesis function they provide is similar to Infino/Flame/Flint software series, but only limited to four-layer picture synthesis, so they are especially suitable for occasions with long space and less complicated stunts. Discreet Logic professional software has become the main software of large professional gold price post-production institutions with its powerful functions, excellent effects and high work efficiency. But because of its high price, not only amateurs, but also many small production organizations are discouraged.

3. Editing/Effects/Painting: Discreet Logic occupies a dominant position in high-end synthetic software, and naturally refuses to give up the low-end market. Edit/Effect/Paint is a series of software launched on PC platform, among which Edit is a professional non-linear editing software, second only to Avid Media Composer equipped with high-end video capture card of Digi Suite or Targa series. Effect is a layer-based composition software, which is similar to the action module in Hell/Flame/Flint. Users can set actions for each layer of the picture, perform operations such as color comparison, image keying and tracking, and also set lighting. One of the great advantages of Effect is that you can directly use the filter designed by Adobe After Effect, which greatly supplements the function of Effect. Since Autodesk became the parent company of Discreet Logic, Effect has put special emphasis on collaboration with 3DMax, which is particularly attractive to many small production organizations and enthusiasts who take 3DMax as their main 3D software. However, as a compositing software, Effect is still a little immature, and many important functions, including keying and manual baffle, are not professional enough, far behind Infino/Flame/Flint and Maya Fusion. Paint is a drawing software, which is equivalent to the drawing module in Inferno/Flame/Flint software. With this software, users can decorate moving pictures conveniently. Some people call it "Photoshop on a moving picture". Because of its vector-based characteristics, strokes can be easily animated to meet the requirements of drawing moving pictures. This software is compact and powerful. It is an excellent drawing software on PC platform and a necessary auxiliary tool for other synthesis software. Discreet Logic Co., Ltd. greatly improves work efficiency by making these three softwares cooperate with each other, such as calling effect and drawing from editing, which is one of the most competitive post-production solutions on PC platform. This year, Discreet Logic Company launched a new composition software Combustion, which integrates effects and painting, and draws lessons from Infino/Flame/Flint series software in terms of interface and function, which is really called "Flint on PC platform". It remains to be seen whether this software will add a heavy burden to the composition software dispute of Discreet Logic on PC platform, and whether Combustion or Maya Fusion will become the king of composition software on PC. However, this competition has prompted the continuous introduction of newer and better synthetic software, which is really a blessing for the majority of producers.

4. Aftereffect refers to composition software on PC platform. It seems hard not to mention Adobe's famous After Effect. Maybe many friends know something about this software. This software has won many supporters because of its simplicity, easy cooperation with Adobe's graphics and image software and a large number of plug-ins. Many friends who mainly do three-dimensional animation and editors who do nonlinear editing with Mac use it for simple synthesis. But compared with all kinds of software mentioned above, this software can only be regarded as an entry-level product. It is certainly competent to synthesize some simple titles or three-dimensional materials generated separately, but it is a bit reluctant for some demanding synthesis tasks, such as fine keying and complex picture details. But from the development trend of software, the gap between amateur software and professional software is always narrowing. With the strength of Adobe, we have reason to believe that After Effect will become a powerful challenger of synthetic software in the near future. Above, we briefly introduced several kinds of synthesis software, of course, there are many excellent synthesis software, such as Composer of AliasWaveront, Media lllusion, Henry and Domino of Ouentel, Softlmage DS and so on. Limited by space, I won't introduce them one by one. If you master the specific use of one or two kinds of synthesis software and understand the principles of digital synthesis technology mentioned in this section, you will find that these softwares are concrete means to realize these principles, and there is not much difference in essence, but the interface form and operation mode are very different. If you can realize this and then learn other synthesis software, it will be a piece of cake. At BIRTV2000, Bell Technology Group launched the latest visual effect production system Combustion* in the history of Discreet Company, and integrated it into the nonlinear editing, rendering and packaging system of Bell Group. Is a powerful visual effect synthesis software, which can solve the work efficiency and visibility you need on NT and Mac platforms. It provides a unique painting, animation and three-dimensional synthesis environment for the creation of visual effects. Cb: 1。 Nonlinear editing system is definitely the general trend of full-function production. Simple editing system is no longer the focus of development. A multifunctional production system integrating powerful editing, rendering and 3D animation will become the backbone of program creation. Combustion* combines the original vector-based painting and animation system paint* and the special effects production system effect*, and integrates the production characteristics and extremely fast cache architecture of inferno*, an award-winning system of Discreet, and develops a new interactive environment for creating visual effects in the desktop system. Combustion* will not only complete all the production effects of the original painting * and effect*, but also provide many high-end production methods transplanted from high-end SGI. Workstation will enrich the rendering means of tasks and make the effect more dazzling. Advanced production tools include: various keying, motion tracking, color adjustment, vector-based lossless painting animation, true three-dimensional image synthesis, network image generation, and support for Adobe Photoshop and After Effects plug-ins. Combustion* is a high-performance software solution, which is not limited by resolution and can output various file formats. It can be integrated with 3D Studio MAX and edit*, and can also be integrated with Discreet's Infino *, flame*, flint*, fire* *, fire* and smoke* systems. Enhance the workflow, integrate discrete systems and software products on the desktop platform, which can be used interactively between any devices. If you use PC as the operating platform of combustion*, you will find that you use the same image rendering tool as SGI workstation! .

2. As a production system for producing top visual effects, the convenience of operation and the characteristics of what you see is what you get are undoubtedly the unremitting pursuit of users. Combustion*' s streamlined and customizable artistic interface design allows you to concentrate on artistic creation. Art cache can see the effect and play back the material in real time. All elements exist in the tree-like infrastructure, and the customized management channels are perfect. When generating continuous images and real-time playback effects, UI operations are allowed. Use basic memory for full-screen playback and composition. A highly balanced architecture supports multiple processors and uses RAM memory to increase visual interactivity and improve work efficiency. Efficient computing architecture ensures the real-time and interactivity of the desktop system.

3. As an advanced system characterized by rendering and packaging, combustion* has absorbed the key drawing, color correction and dynamic tracking technologies of award-winning systems such as discrimino *, flame* and flint*, and transplanted many production functions previously only available in SGI workstation to nt, which not only has the same production method and process as SGI workstation, but also can share production parameters with advanced workstation * *. Successful transplantation enables users to make high-grade visual effects on the desktop platform. (1) Keying combustion* has broken through the limitation of previous keying on the background color, and all kinds of color keying tools and modes provide high keying quality, regardless of color key keying or contour keying. . Combustion* is fully compatible with the key parameters (including input and output) of other special effects editing systems of discreet; With RGB, YUV, HLS, channel, brightness and RGB-CMYK keying mode; Controllable color overflow; Masking control and leveling, shrinkage, erosion and blurring; Create an animated curve mask; Adopt first-class freehand modeling; The mask can use Boolean operations of addition, subtraction, intersection and replacement; The difference keyer compares two images by dragging the key. (2) Color correction Color correction allows producers to control color changes freely without paying too much attention to the quality of the original image and get the desired picture effect. All color correction functions are controlled by channels and have a unified interface; Color correction of other special effects systems that are fully compatible with Discreet; Comprehensive color correction tools, including color balance, brightness/contrast, color scale, gamma, equalization, hue, curve, shadow/midtone/highlight adjustment, etc. NTSC and PAL color restrictions, RGB and HSV color space modes; Accurate automatic color matching function from different materials. (3) Motion tracking and stable motion tracking are unique production effects of high-end production systems. For users who use dynamic tracking technology, the most concern is the tracking speed and whether the calculation can be compensated once the trajectory is lost. Users who use combustion* will not have this concern, because Discreet's dynamic tracker and stabilizer are famous for their accuracy and flexibility, and many years of optimization work have benefited high-end users. Now, more users can enjoy this high-end production method on NT. A complete and cautious high-end tracking tool, which can adjust key frame parameters at any tracking point; Accurate motion analysis is carried out for the tracking of motion, rotation and magnification, and fuzzy objects and off-screen objects are automatically inferred; Share tracking data with Infino *, flame*, flint*, fire*, smoke**** * *, and output the tracking data to other synthesis systems, and input them in the form of ASCII tracking data; Four-point tracking mode; Image stabilization function to control unnecessary camera vibration and jitter.

4. It is obvious that the network can improve the production efficiency, and network generation is undoubtedly the best means for rendering effects that require complex operations. Combustion* has network rendering function. Whether done alone or in cooperation with others, combustion* caters to the needs of many designers * * * to produce large-scale projects with numerous digital details, allowing multiple professionals to cooperate to produce every precise detail of the project. Television designers and animators will be able to work faster and simpler than before, and the production quality and efficiency of programs will be greatly improved. The future development trend is to integrate a variety of non-linear editing, rendering and animation systems. The adoption of network technology can support the interconnection, nesting and calling of various professional equipment, the sharing of materials, the subsection production of programs, the network generation and unified synthesis. The production content is not limited to audio-visual clips and special effects, but also includes the rendering and packaging of programs and the production of three-dimensional animation. Combustion* applies the mature network rendering technology on 3D animation workstation to the generation of video special effects, which represents the latest development direction. Generation: supports multiple and single combustion* workspaces of RenderQueue; Output of multi-generation nodes; After completion, you can send email notifications, parameter statistics, diary files, parameter charts and small movies; Able to run software independently in combustion* and combustion*; RenderQueue can be independently installed on the system for network generation. In addition to the above powerful functions, combustion* also has excellent text, graphics, animation, sound and other processing methods. , especially for the processing of three-dimensional animation and multi-layer image synthesis, providing three-dimensional illumination, three-dimensional camera, three-dimensional volume effect and so on. Combustion* is the latest rendering and packaging system officially released by Discreet on NAB'2000. The edit* nonlinear editing, rendering and packaging system launched by Bell Group was released in China. Its shocking design and free rendering feature endow the edit* system with infinite artistic creation vitality. With the integration of combustion* and edit*, the system concept of "nonlinear editing system: integrating editing, rendering packaging and 3D animation" put forward by Jambers Group has been more perfectly interpreted. Video artists will have powerful tools to create dazzling video effects. Note: The latest CB 3.05d cyberborg...5d is a visual effects software running on IRIX, Linux and Windows 2000. 5D is an extremely important product in the digital art world, and its application in film and television production is increasing. 5d CyberBorg is a brand-new integrated special effects environment, which integrates advanced technology, independent resolution and image processing tools into a temporary new central working environment, which can greatly improve the work efficiency of post-production. In the post-production environment of digital movies and TV, the playback/output of 2K movies and videos of 2D CyberBorg will improve your productivity and your workflow. 5D colossus is a final solution software based on digital level. 5D Monster is a plug-in software with up to 350 kinds of video special effects, which can be used in advanced animation synthesis systems, including Avid D|S, Avid Media Illusion, Fusion, Discreet and advanced post-production system Jaleo. 5D Masher is an off-line special effects and network connection system applied in Quantel system, which can directly connect with third-party special effects such as 5D monster for network connection and storage. Note: The latest version: 2.5 Shake is the software for synthesizing special effects in the movie The Lord of the Rings, and Shake (SK for short) is a powerful software for producing synthetic special effects produced by Nothing Real Company. Similar to DF, the operation idea is based on node architecture. However, it is more open, and you can expand your functions at will by writing scripts. So there are more and more supporters. SK has seven built-in keying tools. They are grouped under key labels in the tool rack. ChromaKey (saturation keying) is a general keying tool, which uses color saturation information for keying. DepthKey is a unique keying tool, which can establish an Alpha channel according to the depth information of an image. DepthSlice is similar to the depth keying tool, which can establish an Alpha channel at any depth position or area according to the depth information of the image. LumaKey (Brightness Keying) is a general keying tool, which establishes Alpha channels according to the brightness difference of images. Primatte:Shake's built-in heavyweight external keying tool, which will be discussed later. Overflow Suppression: Like other tools to limit (clear) the overflow color, it is used to clear the residual background color (blue or green background reflection) on the keying theme. Keylight (Light Keying): A brand-new keying plug-in that won an Oscar. It can accurately control the reflection of blue curtains or green curtains left on foreground objects and replace them with newly synthesized ambient light from the background.
