| I11 |
The signal generated by the largest (11 Bit) pits on a Compact Disc. The Red Book specification for I11 is = or > 0.6 millivolts. |
| I3 |
The signal generated by the smallest (3Bit) pits on a Compact Disc. The Red Book specification for I3 is 0.3 to 0.7 millivolts. As a means of ensuring compatibility with all types of domestic and commercial players. See Red Book |
| Identification and location metadata: |
Anything that can identify a bit of essence media (ie, file source type, location of a videotape, etc.) |
| IEEE 1394 |
(Institute of Electrical and Electronics Engineers) Pronounced "eye-triple-E thirteen-ninety-four" the institute establishes standards and protocols for a wide range of computer and communications technologies, including IEEE 1394, which is a specification FireWire data transmission widely used in DV. Sony refers to the ports on its products with the proprietary term, "i.LINK." |
| Image Enhancer |
Video signal processor that compensates for picture detail losses and distortion occurring in recording and playback. Exaggerates transitions between light and dark areas by enhancing high frequency region of video spectrum. |
| Image Sensor |
See pickup.image sensor |
| impedance |
Opposition to the flow of an audio signal in a microphone and its cable. |
| Imposition |
The drawn indication of the components of a job placed in their final position required for printing. |
| In The Can |
Same as "that's a wrap" to indicate that the scene or program which has been completed. |
| In-camera editing |
Assembling finished program "on the fly" as you videotape simply by activating and pausing camcorder's record function. Reduces or eliminates post-production work, but allows less control over finished program and usually imposes quality concessions. [See edit.] |
| Incident Light |
That which emanates directly from a light source, measured from the object it strikes to the source. [See reflected light.] |
| Indexing |
Ability of some VCRs to electronically mark specific points on videotape for future access, either during the recording process (VISS: VHS index search system) or as scenes are played back (VASS: VHS address search system). |
| Inductive Charging |
A charging system that uses magnetic coupling devices and not metal-to-metal contact plugs. |
| Infrastructure |
Refers to all the parts of a vehicle that make it an Electric Vehicle, except the vehicle itself. |
| input channel |
On an audio board, the control into which a microphone, tape recorder or other source is plugged. |
| Insert Edit |
An electronic edit in which the existing control track is not replaced during the editing process. The new segment is inserted onto a prerecorded black video tape. See also Assembly Edit. |
| Insert Shot |
A close-up shot used to hide an edit or to emphasize a detail. |
| Interlace |
The manner in which a television picture is composed scanning alternate lines to produce one field, approximately every 1/60 of a second in NTSC. Two fields comprise one television frame resulting in the NTSC television frame rate of approximately 30 fps. |
| interlaced video |
Process of scanning frames in two passes, each painting every other line on the screen, with scan lines alternately displayed in even and odd fields. NTSC video is interlaced; most computers produce a noninterlaced video signal. [See noninterlaced video] |
| internal wireless network adapter |
A Wi-Fi adapter that is installed directly into a PC. |
| Interpretive Metadata: |
This can be language descriptions, scene/take, character, camera angle, artists/creators, organizations, etc. Imagine all dialog automatically translated (speech-to-text) and associated and linked to the spoken word. |
| Inverter |
Converts DC electricity into AC electricity so it can be used by a motor. |
| Ion |
An electrically charged particle or molecule. |
| Iris |
Camcorder's diaphragm lens opening or aperture, regulates amount of light entering camera. Size measured in f-stops. [See f-stop.] |
| ISO |
International Standards Organization. |
| ISO 9660 |
An international standard file system devised for CD-ROM discs to enable them to be read on as many computer operating systems as possible. |
