Abstract: An approach is provided for a content management tool for chaining user generated video content. A method includes providing, for display via a social media application, a first recording of a first user participating in a first session that includes first content. The method includes transmitting, by the social media application, the first recording to a plurality of devices. The method includes receiving, through the social media application, a plurality of submissions, from the plurality of devices, that are based on or responsive to the first recording, each submission of the plurality of submissions comprising a second recording of a user of a device of the plurality of devices. The method includes providing, by a cloud-based software tool, controls for selecting one or more submissions of the plurality of submissions to generate an audiovisual work. The method includes providing the audiovisual work for display via the social media application.

Abstract: A system and method for recompressing a JPEG image using requantization is described. DCT transform coefficients for a compressed JPEG image are statistically analyzed to generate a stored numeric error representation. Local minimizers are determined from the stored numeric error representation with selective rounding. A new quantization matrix Q1 is selected from the local minimizers bounded by a target quantization matrix Qbound. The compressed JPEG image is recompressed using the new quantization matrix Q1.
