Digital Media Literacy Quiz Answer Key Fall 2016

• True or False: A text transcript can be embedded within a mp3 file, in addition to the audio data.

True: MP3 files usually contain track data embedded within the file in addition to the audio data. This additional data is contained in ID3 tags and typically include the track’s title, artist and album details. However, these tags are much more versatile and can also include an image or illustration, and an entire transcript.

• An audio filter that adjusts the gain of a file so that the greatest peak level is lower or equal to a set decibel level. Select one: , normalization, .

The correct response is normalization. Equalization is the boosting or reduction of the levels of different in a signal (treble, bass). Ducking is when the level of one audio signal is reduced by the presence of another signal.

• An audio filter that reduces sound that exceeds a certain threshold level, smoothing out the dynamics and increasing the overall volume. This filter helps bring the key frequencies of an audio clip into range, while preventing softer parts from becoming inaudible. Select one: Compressor, limiter, FatEQ.

The correct response is Compressor. The Limiter works much like a compressor but with one important difference. Where a compressor proportionally reduces the signal when it exceeds the threshold, a limiter reduces any peak above the threshold to the threshold level, effectively limiting the signal to this level. An equalizer (commonly abbreviated as EQ) shapes the sound of incoming audio by changing the level of specific bands. The Fat EQ provides up to five individual frequency bands, graphically displays EQ curves, and includes a set of parameters for each band.

• A ______artist recreates the realistic ambient sounds that a video production portrays. Select one: FX, sound effects, foley.

The Foley artist is the person who recreates or enhances many of the natural, everyday sound effects in a production. The term Foley artist is named after Jack Foley, one of the earliest and best-known Hollywood practitioners of the art. Foley began his career in the film industry as a stand-in and screenwriter during the silent era, and later helped Universal make the transition from silent movies to talkies.

• An or combination of colors that are carefully selected to capture the attention and/or set a mood for the user when viewing a project. Select one: Color scheme, color profile, color gamut.

The correct response is color scheme. A color profile is a numerical model of a color space. Operating systems and programs need to have access to a profile that describes the meaning of the color values in order to interpret the color correctly. Color gamut is a measure on how large the color range of a monitor is.

• In topography, ______is the process of adjusting space between individual letter forms. Select one: Leading, tracking, kerning.

The correct response is kerning. Leading refers to the vertical distance between the baselines of successive lines of type, often referred to as line spacing. Tracking is the process of adjusting the spacing uniformly over a range of characters.

• Vector based file types are constructed with lines and fill colors using mathematical formulas, and are excellent for creating graphics that frequently require resizing without compromising resolution. Raster images are constructed using a fixed number of colored pixels, cannot be scaled up without compromising their resolution. Raster images that are enlarged often appear pixilated or blurry. Check only the vector based file types included in this list: .ai, .eps, .gif, .jpg, .png, .svg, .tif.

An .ai file (Adobe Illustrator) is the default file type of Illustrator, a popular vector-based program. An .eps file (Encapsulated PostScript) is a vector file that can be opened outside of Illustrator. A .gif file (Graphics Interchange Format) is a raster image format best used for simple images made up of solid colors with no gradients. A .jpg file (Joint Photographic Experts Group) is a raster image format best used for displaying images on the web. A .png file (Portable Network Graphics) is a raster image format best used for displaying simple images; this file type supports transparency. A .svg file (Scaleable Vector Graphics) is a XML-based vector image format supported by web browsers. A .tif file (Tagged Image File Format) is a raster image format best used for high-resolution images.

• Select the video editing option that created the visual effect shown below on the far right. Select one: Layering, compositing, masking. The correct response is Compositing. Composite modes mathematically determine how the brightness and color of one clip visually interacts with those of another clip layered beneath it in a sequence. Layering is the process of stacking clips above one another in the Project Timeline. Masking is the process of applying filters to matte out areas of a clip.

• Select the motion option that created the animation of the triplicate Photoshop files in this video shown below. Select one: Particle emitter, replicator, tweening. The correct response is Tweening. Tweening is short for in-betweening, the process of automatically generating intermediate frames between two selected frames. By creating position, scale, opacity, and rotational differences on these frames, the software will automatically generate the in-between frames and produce a smooth animation. The particle emitter in Motion5 creates a continuous stream of objects that can be controlled by numerous factors including amount, direction, spin, and scale. The replicator in Motion5 creates a fixed pattern of objects that can be animated to create a variety of complex patterns and backgrounds.

• Select the motion behavior that created the animation of the images in this video shown below. Select one: Motion path, keyframing, camera sweep.

The correct response is Camera Sweep. By adding a camera to a scene, you can orbit the camera around a point of interest in 3D with framing and sweep behaviors. A motion path behavior applied to an object creates an animation of the object moving on a set path. Keyframing is animation that occurs by creating two keyframes at different points in time and changing clip parameters (position, scale, rotation, etc.) on at least one of the keyframes.

• In a film or video production, a C47 refers to what? Select one: HMI light, diffusion filter kit, clothespin. The correct response is Clothespin. In the early days of Hollywood, studio heads auditing equipment requests from lighting departments could not understand spending money for something as simple as clothespins. “Clothespin” was quietly changed to the more impressive-sounding C-47. Clothespins are used in video work to attach gels to lights. HMI (Hydrargyrum Medium-Arc Iodide) is a type of light that uses an arc lamp instead of an incandescent bulb to produce light. A diffusion filter kit consists of an assortment of light-softening sheets that can be used by photographers and videographers to affect the character, shape and quality of the light.
