3:2 pulldown, also called 3-2 pulldown, is a method of converting 24 frame per second (fps) motion picture video to 60 fps video, such as NTSC. In 3:2 pulldown, one frame of the film is scanned three times, the next frame is scanned twice, the next frame is scanned three times, and so on. Progressive scan (non-interlaced) video uses 3-2 pulldown.
- 3-D audio
A technique for giving more depth to traditional stereo sound. Typically, 3-D sound, or 3-D audio, is produced by placing a device in a room with stereo speakers. The device dynamically analyzes the sound coming from the speakers and sends feedback to the sound system so that it can readjust the sound to give the […]
- 3-D graphics
The field of computer graphics concerned with generating and displaying three-dimensional objects in a two-dimensional space (e.g., the display screen). Whereas pixels in a 2-dimensional graphic have the properties of position, color, and brightness, a 3-D pixels adds a depth property that indicates where the point lies on an imaginary Z-axis. When many 3-D pixels […]
- 3-D software
The category of software that represents 3-dimensional objects on a computer. This includes CAD/CAM, computer games, and animation packages.
3ivx is an MPEG-4 toolkit that supports MPEG-4 Video, MPEG-4 Audio and the MP4 file format. 3ivx allows video and audio to be compressed to a fraction of its original size while maintaining high image quality.
- 45 nanometer
45 nanometer (45 nm) is the buzzword of choice (2007-2008) for an advanced semiconductor manufacturing process that Intel used for mass chip production, starting in late 2007. The 45 nanometer manufacturing process uses new materials, including hafnium-based high-k gate dielectrics and metal gates, to reduce electrical current leakage in transistors. Contrast with 90 nanometer.
