Abstract: A system and method are disclosed for transcoding a video clip. In one implementation, a computer system determines N frames at which to divide a video clip into N+1 consecutive chunks, where N is a positive integer, and where the frames are determined based on the image content of the video clip, a minimum chunk size, and a maximum chunk size. Each of the N+1 chunks is provided to a respective processor for transcoding, and a transcoded video clip is generated from the transcoded N+1 chunks.

Abstract: A system and method for detecting media source quality are provided. The system includes a data store comprising a computer readable medium storing a program of instructions for the detection of media source quality; a processor that executes the program of instructions; a video data receiver to receive video raw data, the video raw data corresponding to an uploaded and transcoded video; a video improver to apply a video improvement technique to the received video raw data to produce a modified version of the video raw data; and a video quality assessor to compare the received video raw data and the modified version of the video raw data, and based on the modified version of the video raw data improving on a factor associated with the video improvement technique, the video quality assessor indicates a phenomenon affecting the quality of the uploaded and transcoded video.
