Concepts and technologies disclosed herein are directed to audio and video synchronization. According to one aspect disclosed herein, an audio-video ('AV') synchronization system can simultaneously capture samples of a pre-encode media stream and a post-encode media stream. The pre-encode media stream can include AV content prior to being encoded. The post-encode media stream can include the AV content after being encoded. The AV synchronization system can align a pre-encode video component of the pre-encode media stream with a post-encode video component and can determine a video offset therebetween. The AV synchronization system can align a pre-encode audio component of the pre-encode media stream with a post-encode audio component of the post-encode media stream and can determine an audio offset therebetween. The AV synchronization system can then compare the video offset and the audio offset to determine if the post-encode media stream is synchronized with the pre-encode media stream.
