Abstract: Techniques are generally described for catch-up pacing for video streaming. In various examples, a camera may capture first video data representing a physical environment. In some examples, motion in the physical environment may be detected from the first video data. A communication channel may be established with a remote computing device. In some examples, the camera may capture second video data. In various examples, the second video data may be captured during a period of time corresponding to the establishment of the communication channel. An available bandwidth of the communication channel may be determined. The available bandwidth may comprise a first bitrate. Third video data may be captured by the camera. The third video data may be encoded at a second bitrate lower than the first bitrate. The first video data, second video data and third video data may be sent to the remote computing device.
