Metadata

Metadata- Quite simply metadata is data within data. It refers to all of the info that a video or audio file might contain (timecode, scene, take, cam roll, etc). Through the use of software, Digital Chromatics can alter the metadata if needed.

Moiré

Moiré – Refers to a distortion that appears as patterning seen on images where two similar fine patterns overlap, for example two fine gratings can appear to produce diagonal lines. The affect can appear even when one to the patterns is normally invisible, such as the sampling frequency of the image. In a good image system this should be avoided by use of filters but, for instance, the fine detail of a grid pattern may suddenly collapse and appear as curves or diagonal lines as the camera zooms in and the pattern detail nears the digital sampling frequency.

MXF - The Material eXchange Format is aimed at the exchange of program material between file servers, digital video recorders, editing systems, tape streamers and digital archives, etc. It is a container, or wrapper, format that supports a variety of differently coded streams of essence (images and sound), together with metadata describing the material in the MXF file.

Non Drop-Frame Timecode

Non Drop-Frame Timecode - Timecode that does not use drop-frame and always identifies 30 frames per second. This way the timecode running time will not exactly match normal time unless it is an exact 30f/s. The mismatch amounts to 1:1000, an 18-frame overrun every 10 minutes.

Offline vs Online Editing

Offline vs Online Editing- Offline is typically editing with lower resolution footage on a large project where storage is an issue. The footage is captured and edited until the project is cut and then recaptured at full quality and finished for the Online editing.

One Light Pass

One Light Pass - A one-light pass refers to a film-processing lab giving the same exposure to a defined length of film, during printing. This is the simplest, quickest and cheapest way to print all the film and the results are typically used for making rushes, dailies, etc. These are often subsequently telecined and recorded to videotape as a reference for the offline decision-making process.

Original Camera Negative

Original Camera Negative (OCN) - This is the exposed and developed negative film from the camera. Initially it is the only visual record of a shoot and so is highly valuable. Before digits got involved with film the OCN had to withstand being cut, edited and copied to a make a few master interpositives. Now it can be run just once through a film scanner and then put on the shelf. This reduces the risk of damage and makes a digital copy, that itself can easily be copied for further security.
