  • Publication number: 20230188764
    Abstract: A processing system may identify at least one feature set of a first video program, the at least one feature set including a complexity factor, obtain predicted visual qualities for candidate bitrate and resolution combinations of the first video program by applying the at least one feature set to a prediction model that is trained to output the predicted visual qualities for the candidate bitrate and resolution combinations of the first video program in accordance with the at least one feature set, select a bitrate and resolution combination for at least one variant of the first video program in accordance with the predicted visual qualities for the candidate bitrate and resolution combinations of the first video program, and transcode the at least one variant of the first video program in accordance with the bitrate and resolution combination that is selected for the at least one variant.

  • Publication number: 20220360843
    Abstract: 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.
