2.4 Media Formatting - all

The part of a sound wave that is captured, measured, and assigned a numeric value during digital sound recording.

• Sample

• Sampling Rate

• Vector Images

• Raster Images

The amount of memory used to store the numeric value of a sound sample during digital sound recording. 8-bit sound uses eight bits (or one byte) to store the value of each sample.

• Lossless Compression

• Bitrate

• Ray Tracing

• Bit Depth

The number of individual samples taken each second during digital sound recording

• Frame Rate

• Resolution

• Color Depth

• Sampling Rate

The number of images, or frames, that are taken each second during digital video recording. Most digital videos have a frame rate of about 30 frames per second

• Frame Rate

• Color Depth

• Resolution

• Sample

The number of pixels in the width and height of each frame in a digital video recording. The higher the resolution, the clearer the image will be.

• Resolution

• Frame Rate

• Bit Depth

• Lossless

The amount of memory the computer uses to display colors in a digital image or a digital video. 8-bit color images use one byte of data for each pixel. 24-bit color uses three bytes for each pixel.

Which are examples of Lossy Compression?

• JPG

• MP3

• MP4

• PNG

• PDF

A common lossless compression algorithm that looks for repeated patterns of bits or bytes and records the pattern and the number of times the pattern is repeated.

• Run-Length Encoding

• Lossless Compression

• Compression Artifact

• Lossy Compression

A patch of pixels in a compressed image or video that have less visible detail than the rest of the image.

• JPEG

• ZIP
