Abstract: Computer-aided computer system configuration techniques for adding new computing resources to an existing set of computing resources. A method embodiment commences upon identifying an existing computing system having a first set of configuration parameters. A second computing system having a second set of configuration parameters is deployed. A user interface is provided to accept user input comprising a location and protocol to access the existing computing system. Syntactical and semantic differences between the configuration parameters of the existing computing system and those of the newly added set are identified. The identified differences are analyzed to generate a parameter map that relates the existing set of configuration parameters to the second set of configuration parameters and vice-versa. Relationships that are codified in the parameter map are validated through user interactions.

Abstract: Systems, methods, and non-transitory computer-readable media receive a source video having a source file size. A bit rate at which to encode the source video is determined. The source video is encoded at the determined bit rate to produce an encoded video having a file size less than the source file size. A video quality metric for the encoded video is determined. Whether or not the video quality metric for the encoded video is within an allowable deviation from a target quality metric is determined. The source video is encoded at another determined bit rate when the video quality metric for the encoded video is outside the allowable deviation from the target quality metric. Determining the bit rate and encoding the source video at the determined bit rate can repeat iteratively until the video quality metric for the encoded video is within the allowable deviation from the target quality metric.

Abstract: Systems, methods, and non-transitory computer-readable media receive source video content, encode the source video content by a first encoding process to produce compressed video content, apply edge detection to the compressed video content to produce first edge-detected video content, and encode the first edge-detected video content by a second encoding process to produce first encoded video content. The systems, methods, and non-transitory computer-readable media may further equalize the source video content by an equalization algorithm to produce equalized video content, apply edge detection to the equalized video content to produce second edge-detected video content, and encode the second edge-detected video content by the second encoding process to produce second encoded video content. The systems, methods, and non-transitory computer-readable media may compare the first encoded video content and the second encoded video content, and adjust the first encoding process based on the comparison.
