  • Patent number: 11856214
    Abstract: One or more computing devices, systems, and/or methods for video encoding are provided. For example, a video file may be segmented into at least a first portion and a second portion. The first portion may be analyzed to determine that the first portion is associated with a first level of complexity, and the second portion may be analyzed to determine that the second portion is associated with a second level of complexity. A first bitrate associated with the first level of complexity may be determined, and a second bitrate associated with the second level of complexity may be determined. The first portion may be encoded at the first bitrate to generate a first encoded portion, and the second portion may be encoded at the second bitrate to generate a second encoded portion. The first encoded portion and the second encoded portion may be assembled to generate an optimized video file.

  • Publication number: 20160353107
    Abstract: Methods and systems provide an adaptive quantization parameter (QP) modulation scheme for video coding and compression that is sensitive to user visual perception. In an embodiment, the method includes detecting an eye sensitive region, where a region is considered sensitive based on a noticeability of a visual effect. The method includes estimating encoding parameters for image content in the detected eye sensitive region. The method further includes encoding the detected eye sensitive region with the estimated encoding parameters. The estimating the encoding parameters may be based on, among other things, a variance, a motion vector, a DC value, an edge value, and external information such as a user command or screen content. The encoding may include storing an average or maximum sum of square differences (SSD) value for a detected eye sensitive area and adjusting a QP value based on a comparison of the SSD value to generated threshold values.

  • Publication number: 20100118940
    Abstract: A device incorporates an H.264 compatible video encoder for providing compressed, or encoded, video data. The H.264 encoder comprises a buffer for storing previously coded macroblocks of a current picture being encoded; and a processor for generating adaptive reference picture data from the previously coded macroblocks of the current picture; wherein the adaptive reference picture data is for use in predicting uncoded macroblocks of the current picture.

  • Publication number: 20090268810
    Abstract: The use of parametric models to capture and represent local signal geometry allows a new geometric intra prediction scheme to better encode video images. The encoding scheme gives the video encoder the flexibility and scalability to match the video frame content with the desired computational complexity. It also allows the encoder to encode the images more efficiently using intra prediction because it reduces the artificial edges that occur during standard intra encoding.
