Glossary of Terms

Below is a list of terms often used by our Support team when communicating with our customers. This glossary serves as a very basic overview of how we would be using the term in conversation. While some of these terms may have much more detailed or technical definitions when used in other context, we hope that these quick definitions help to clarify our own usage and intent.

Aspect Ratio

The correlation between width and height of an image or video. The most common variants are 4:3 (traditional televisions) and 16:9 (widescreen and HD).

Bandwidth

A measurement of the amount of data transferred from a server to all consumers. Calculated by taking the size of the file stored on a server, and multiplying by the number of times that file has been downloaded.

Bit Rate

The amount of image or audio data delivered over a period of time. For video, a higher bit rate will mean larger file size and longer load times, but possibly better quality

Canvas

The visual workspace for a video or image. Represents what will be seen in the final product.

Chroma Key

Removing a particular color and replacing it with transparency. In video, this effect is often used to remove a solid background color so the original image can be superimposed on a new background. Also known as blue/green screen.

Clip

A piece of media on the timeline, with a finite duration.

Codec

Short for compressor/decompressor. A piece of software that provides specific control over how video files are created or viewed.

Compression

A way of encoding a file to reduce file size but still maintain high quality.

Constant Framerate

A video file that has a set number of frames that display each second. Videos encoded with a constant framerate will play back more consistently in video players and editing software than those encoded at a variable framerate.

Crop

Removing material from the outside edge of a video or image to put focus on a certain area and reduce the dimensions of the media.

Dimensions

The width and height (in pixels) of an image or video.

Embed

Embedding content on a website or blog allows it to play or display within the page without launching an external player or a new browser window.

Encode

The process of creating a video file using specific settngs such as bitrate, format, framerate, audio frequency, etc.

Export

To take a file and create a standalone copy for sharing and viewing, without requiring the original application.

Format

A term for the variety of ways information can be saved to a file. Image, video, and audio files will all have their own unique formats that provide certain features, benefits, or drawbacks.

Frame

A single static image from a video file. The series of frames playing one after another creates a video.

Frames Per Second (FPS)

The number of individual images that show for every second of time in a video file.

H.264

The most common video compression format used for MP4 files. Also used by Snagit and Camtasia.

HD/High Definition

A video file that has a resolution higher than 640x480. Common standards are 1280x720 or 1920x1080.

Import

Bringing a piece of media into another application for editing.

Letterboxing

When a video with a widescreen aspect ratio is displayed at a standard size, but maintains the widescreen aspect ratio. This results in black bars above and below the video.

Media

Any image, audio, or video file.

Mono

Short for monophonic, mono sound only has one channel. That single channel of audio may play through the left and right channels simultaneously, or one or the other respectively.

Picture-in-Picture (PIP)

The visual effect of one video playing in a small region, overlayed on a larger video that is also playing. Commonly used in conjunction with webcams.

Pillarboxing

When a video with a standard aspect ratio is displayed at a widescreen size, but maintains the standard aspect ratio. This results in black bars to the left and right the video.

Pixel

A unit of measurement on a computer display. Unlike physical measurements like centimeters or inches that have a set size, a pixel is a digital unit that can appear different in size depending on the display. Measurements for dimensions and resolution are done based on the pixel unit.

Player

An application, webpage, or piece of code used to interpret and display a piece of media. Different players will offer different features such as pausing, speeding up or slowing down video, table of contents, quizzing, or interactive hotspots.

Playhead

Visual indication of what point in time you are viewing a piece of media.

Produce

To take a file and create a standalone copy for sharing and viewing, without requiring the original application.

Render

To take a file and create a standalone copy for sharing and viewing, without requiring the original application.

Resolution

The width and height, in pixels, of an image or video.

Ripple delete

When a clip, or section of a clip, is deleted and the subsequent clips move in to fill the gap.

Scale

Changing the display dimensions of an image or video in order to make it appear larger or smaller.

Scrub

Dragging the playhead along a timeline in order to see or hear a preview.

Stereo

Short for stereophonic, stereo sound has a distinct left and right channel. Both channels play back at the same time, and each typically has different audio or information.

Timeline

The area where media is arranged to create a video. The video will show all media, playing from left to right.

Trim

Cutting or deleting a section of video at the very begining or end.

Putting content out to a web server for sharing online.

Variable Framerate

A video file that will have different framerates depending on the amount of motion or change in the visual data. High motion areas will have a higher framerate, while static or low motion sections will be a low framerate. Used to reduce overall filesize of videos.

Waveform

Visual representation of audio levels at a point in time. The higher the wave, the higher the audio levels.
