ChromaĬhroma describes the intensity and purity of a color, or the colorfulness. For color channels, there are modes such as RGB, YUV, and HSV.įor instance, RGB mode has three channels: red, green, and blue, with each channel being a grayscale image in its respective color in association with the source image. C ChannelsĬhannels refer to color channel that stores color information and alpha channel that contains transparency information. Recommended bitrate for various resolutions are: 35-45 Mbps for 4K, 16 Mbps for 2K, 8 Mbps for 1080p and 5 Mbps for 720p. A higher bit rate usually corresponds to better image quality and hence a larger file size. Bit Rateīit rate is the amount of data contained in video and audio streams in a second, measured in Mbps (megabits per second).

8-bit color permits 2^8 = 256 steps of color values in a pixel for each channel, that amounts to 256x256x256 = 16,777,216 (over 16.7 million) colors. B Bit Depth (Color Depth)īit depth refers to the number of bits used to define RGB channels (Red, Green, Blue). It can be seen as the draft of the story before the rough cut, and it is usually 2 to 3 times the duration of the final cut and the released version. It is done after the editor reviews all the footage and has a general idea of how the story goes by. AssemblyĪssembly edit, or first assembly, is the process to arrange footage on the timeline to create a story outline. For instance, an image with 6000 pixels horizontally and 4000 pixels vertically has an aspect ratio of 6000:4000, or 3:2 when reduced to the lowest terms.Ĭommonly seen aspect ratios for videos are 4:3, 16:9, 21:9 (widescreen), 1:1 (Instagram square video), and vertical screen 9:16, 3:4. Aspect RatioĪspect Ratio describes how wide an image is in relation to its height proportionally. A smaller F-number corresponds to a larger aperture that allows more light to hit the sensor.Ī larger aperture (lower f/stop) will result in a shallow depth of field, creating background blurriness for aesthetic concerns.Īperture, shutter speed, and ISO are the main factors that influence exposure in photography and videography. It is written as f/number (f/2.8, f/4, f/5.6), which represents the focal length of the lens. ApertureĪperture controls the amount of light passing through the lens since it is the hole on the diaphragm. Traditionally, it involves the drawing of successive images on celluloid paper and later evolved into a computer-aided process.Īnimation types include hand-drawn animation, 2D and 3D animation with CGI, motion graphics, and stop motions featuring puppets, paper cutouts, and clay figures. AnimationĪnimation is the process of creating an illusion of motion by manipulating a series of figures. For videos, Apple ProRes 4444, HEVC, and WebM. Image formats such as PNG, TIFF, and GIF can contain alpha information. It tells the video editing software which part is transparent in the footage.Īn alpha matte feature in the capable software can create matte based on the alpha information, thus separating certain parts of the image from its surroundings.

AlphaĪlpha channel stores the transparency information of images or videos. In non-narrative videos or interviews, A-Roll usually involves the talking head that focuses on the story going on, while B-roll acts as supplementary for additional information or visuals. Stay tuned! A A-RollĪ-Roll is the primary footage that tells the story or the main plot. We've outlined an A-Z list of the most popular and important terms and definitions in video editing and videography.Īlso, we will update our video editing terminology glossary regularly. Some of them you may have known, but some of them you may not be familiar with.ĭon't worry. New to filmmaking or post-production? There may be hundreds of terminologies in this video editing industry.
