Definition
Bitrate determines how much of the picture's information is preserved each second. It works together with the codec and is separate from resolution and frame rate, though more pixels and more frames per second need a higher bitrate to stay clean. There are two encoding modes: CBR (constant bitrate) uses the same data rate throughout for predictable file sizes, which suits live streaming; VBR (variable bitrate) spends more data on complex scenes and less on simple ones, giving better quality per file size, which is standard for uploads. Too low a bitrate produces artifacts; too high wastes storage with no visible benefit. Platforms publish recommended upload bitrates per resolution and frame rate.
How Loopdesk Uses This
Loopdesk's export presets set an appropriate bitrate (along with codec, container, resolution, and frame rate) for each platform automatically, so creators get clean, correctly-sized files without hand-tuning Mbps in an export dialog.
Frequently Asked Questions
What is the difference between bitrate and resolution?
Resolution is how many pixels are in each frame (sharpness); bitrate is how much data is used per second (compression quality). A 4K video at a low bitrate can look worse than a 1080p video at a high bitrate.

Video Codec
The technology that compresses video into a smaller file and decompresses it for playback — e.g. H.264, H.265, AV1, ProRes.
Frame Rate (fps)
The number of still frames a video shows each second (fps); it controls motion smoothness and 'feel', not sharpness.
