The transparency information stored in an image or video, alongside its red, green and blue color data.
The proportional relationship between a video or image's width and height, written as two numbers like 9:16 or 16:9.
A royalty-free codec built for streaming efficiency, offering meaningfully smaller files than H.264 or even VP9 at the same quality.
How much data a video or audio file uses per second of playback, usually measured in Mbps (video) or kbps (audio).
The maximum number of characters a platform allows in a post's caption - it varies enormously, from 280 on X to over 60,000 on Facebook.
The algorithm that compresses video or audio data - H.264 and AAC are the two you'll run into most, packed inside a container like MP4.
A file format like MP4, MOV or WebM that wraps a video stream, an audio stream and metadata together - it's the packaging, not the compression.
How many individual images ("frames") a video shows per second, measured in FPS. 24, 30 and 60 are the common values.
The most widely supported video codec, decoded natively by essentially every phone, browser and TV made in the last fifteen years.
A newer codec that roughly halves file size versus H.264 at similar quality, at the cost of narrower playback support.
The standard compressed photo format - small files, no transparency, accepted everywhere.
A fully-encoded frame in a compressed video, placed periodically so playback and editing can jump to that point without decoding everything before it.
Lossless compression shrinks a file without discarding any data; lossy compression discards data a viewer is unlikely to notice, for a much smaller file.
Apple's QuickTime container - the default export from iPhone camera rolls and Final Cut Pro.
The most widely compatible video container, accepted by every social platform, phone and editor.
A lossless image format that preserves transparency - the standard choice for logos, screenshots and graphics with text.
The pixel dimensions of a video or image - width × height - which determines how much detail it can show.
The area of a video kept clear of interface overlays, where important text, faces and graphics are less likely to be obscured.
Converting a video or audio file from one codec, container or bitrate to another - decompressing it, then compressing it again in the new format.
Google's open, royalty-free codec, typically paired with the WebM container, delivering H.264-level quality at roughly 30–50% less data.
An open, web-native video container - typically VP9 or AV1 video with Opus audio - built for smaller files on the open web.
An image format supporting lossy and lossless compression plus transparency; the quality and file size depend on the selected mode and source image.
Bitrate, resolution, frame rate and codec explained in the order they actually matter - and why a 4K video can be smaller than a 1080p one.
