This Blog Post Is Purely To Document The Meanings Of All These Key Terms For Future Reference. As part of a VFX Pipeline.
- Modelling :
“the activity of making three-dimensional models.”
2. Pre Vis
“Previsualization (also known as previs, pre-rendering, preview or wireframe windows) is a function to visualize complex scenes in a movie before filming. It is also a concept in still photography.”
3. High Dynamic Range Photos
“High–dynamic–range imaging (HDRI or HDR) is a technique used in imaging and photography to reproduce a greater dynamic range of luminosity than is possible with standard digital imaging or photographic techniques.”
4. Reference Photos
“Photo-referencing, rather than working with live models, is useful for cases in which an artist seeks to realistically produce a work of art based on some subject that is not readily available, such as specific person who is not there or a structure in another country.”
5. LIDAR
“a detection system which works on the principle of radar, but uses light from a laser.”
6. Texturing
“Texture mapping is a method for adding detail, surface texture (a bitmap or raster image), or color to a computer-generated graphic or 3D model.”
7. Rigging
“Skeletal animation is a technique in computer animation in which a character is represented in two parts: a surface representation used to draw the character (called skin or mesh) and a hierarchical set of interconnected bones (called the skeleton or rig) used to animate (pose and keyframe) the mesh.”
8. Tracking and Match-Move
“With motion tracking, you can track the movement of an object and then apply thetracking data for that movement to another object—such as another layer or an effect control point—to create compositions in which images and effects follow the motion.”
“In cinematography, match moving is a cinematic technique that allows the insertion of computer graphics into live-action footage with correct position, scale, orientation, and motion relative to the photographed objects in the shot.”
9. Film Scans
“A film scanner is a device made for scanning photographic film directly into a computer without the use of any intermediate printmaking.”
10. Tests
“We test things to check how they run and how they will look , a test is not the final result of a piece however it can help guide a final product”
11. Animation
“the technique of photographing successive drawings or positions of puppets or models to create an illusion of movement when the film is shown as a sequence.”
12. Rotoscoping
“transfer (an image from live action film) into another film sequence using a rotoscope.”
13. Grading
“Color grading is the process of altering and enhancing the color of a motion picture, video image, or still image either electronically, photo-chemically or digitally.”
14. Compositing
“combine (two or more images) to make a single picture.”
15. Effects animation
“In computer animation, effects animation is the animation of any non-character elements, such as fire or rain.”
16. Lighting and Rendering
“Rendering is the process of creating temporary video and audio renderfiles for segments of your sequence that Final Cut Pro cannot play in real time. When you render a segment of your sequence, Final Cut Pro substitutes a render file for the segment during playback.”
17. Plate Preparation
The visual effects process begins with a number of ingredients. The first ingredient in the mix is the film or video that was shot. This usually consists of a series of still images (as opposed to movie formats like quicktime) and are referred to as ‘plates’ (as in film plates). These usually consist of a sequence of digital files that are the digital scans of the original film that was shot. These are the source images and, in theory, the only thing they are missing are the visual effects.
