Bitrate

Bitrate measures the data throughput of a video file, typically expressed in megabits per second (Mbps). Higher bitrates allocate more data to each second of video, allowing the codec to preserve finer visual details with fewer compression artifacts.

For lip sync output, bitrate is particularly important because the subtle details that make lip sync convincing, such as teeth edges, lip textures, and fine skin details, are exactly the kind of high-frequency information that aggressive compression destroys first. Production lip sync workflows typically use higher bitrates than standard video to preserve the quality of the generated mouth region, especially when the output will undergo further compression during distribution.

Bitrate relates to several other concepts in the AI lip sync pipeline: Codec , and Resolution .
