Building Blocks of Editing Sequence

Scripted action and dialog- the actor or host will have to perform a scene using a script that has been memorized or using a teleprompter.  In this case many takes are made in order for the director to have a good scene. Unscripted action and dialog- footage is usually shot using real world subjects and nothing is scripted.  Examples of this could be an interview or a documentary of an animal. Full-Screen graphics- it can take up the full screen and does not have to be superimposed with another video source. Music and sound effects- these should be imported into … Continue reading Building Blocks of Editing Sequence

Redundancy

Redundancy is the amount of wasted space that is consumed  by storage media to record picture information in a digital image. Spatial redundancy is when the value of a pixel remains unchanged in each frame. Temporal redundancy is when the value of a pixel remains unchanged from one frame to the next in a time-based sequence. Continue reading Redundancy

Compression

Intraframe compression eliminates spatial redundancy from within a video frame . Interframe compression exploits the spatial and temporal redundancy. The process of compression is to reduce the file size of an image by eliminating or rewriting as much of the redundant information as possible.  It is also done to retain the visible quality of an image.  The goal is to conserve the bandwidth by eliminating spatial and or temporal redundancies.

Omnidirectional microphones respond equally to sounds from all directions.  This microphone would be perfect for a performance from a band and a choir together. Bidirectional microphones pick up sound equally from the front and rear. This microphone would be good to use in a lecture where the professor may ask questions and accept questions from the audience. Cardioid microphones pick up sound only from one direction.  This microphone would be good to use if a professor is giving a lecture that is being recorded and wants no questions or in a live concert so only the voice of the singer … Continue reading 13.1.1

Codec is short for coder-decoder.  It is a computer program or algorithm designed for encoding and decoding audio and video into a raw digital bit stream. A container is a unique kind of file format used for bundling and storing the raw digital bit streams that codecs encode. Continue reading 12.1.3

Sampling rate is the number of samples of audios carried per second.  Sampling rates are measured in kilohertz.  The human hearing has a frequency range of 20 Hz to 20 kHz this means a minimum of 40 kHz is required in order to effectively capture all frequencies within the range.
