Abstract
Techniques for output frame correction for unstable video streams are described herein. A video item may be transmitted via an input video stream from a first entity to a second entity over one or more electronic communications networks. The incoming frames from the input video stream may then be used, by the second entity, to generate an output video stream for presentation to one or more viewers. The transmission of the input video stream may temporarily become unstable and may be interrupted such that one or more frames of the input video stream are delayed and/or lost. When a transmission interruption is detected, the output video stream may be adjusted by inserting one or more correction frames into the output video stream. The inserted correction frames may include one or more repetitions of one or more prior frames in the output video stream and/or one or more interpolated frames.
