1. A system for classifying videos based on video content, comprising:

  • a processor;

    one or more software modules including one or more classifiers;

    a computer program product that includes a computer-readable medium that is usable by the processor, the medium having stored thereon a sequence of instructions associated with the one or more software modules that when executed by the processor causes the execution of the steps of;

    receiving a video file, the video file including a plurality of frames;

    extracting a subset of frames from the video file;

    if one or more frames in the extracted subset of frames comprises a dark frame, discarding the one or more dark frames from the subset;

    determining whether each frame in the extracted subset includes content associated with a general content category;

    for each frame in the extracted subset that includes content associated with the general content category, generating a scene classification score vector for the frame via one or more scene classifiers, the scene classification score vector including one or more scene classification scores associated with one or more predefined scene categories within the general content category;

    determining a representative scene classification score vector for the video file based on the generated scene classification score vectors for each extracted frame in the subset that includes content associated with the general content category; and

    associating the video file with the one or more predefined scene categories based on the representative scene classification score vector.
