Bit Rate is the amount of data processed per second in a video or audio file, typically measured in megabits per second (Mbps). It is one of the primary factors that determines the quality, file size, and playback smoothness of digital video content.

Higher bit rates preserve more visual detail and produce cleaner, sharper video, particularly during fast motion or in scenes with complex textures and gradients. Lower bit rates result in smaller file sizes but introduce compression artifacts, banding, and loss of fine detail. The right bit rate depends on the intended delivery platform, with streaming services, broadcast, and local playback each having different requirements and tolerances.

When exporting AI-generated video content, understanding bit rate helps creators make informed decisions about the trade-off between quality and file size. Most professional platforms recommend a minimum bit rate for uploads, and outputting below that threshold can result in visible quality degradation even if the original generated content was high quality.
