05. Extracted Metadata

In addition to the machine learning components, the software extracts other video metadata. The full list of all metadata that is generated through processing is provided here:

Video information:

• General_FileExtension - File extension (eg. mp4,ogv...)
• General_Format_Commercial - Official extension name (eg. MPEG-4)
• General_FileSize - File size (in bits)
• General_Duration - Video duration (in milliseconds)
• General_OverallBitRate_Mode - Bit Rate Mode (eg. VBR)
• General_OverallBitRate - Bit Rate per second
• General_FrameRate - Number of frames per second
• General_FrameCount - Total Number of frames
• General_Encoded_Date - Timestamp of encoding date
• General_File_Modified_Date - Timestamp last modified date
• General_File_Modified_Date_Local - Timestamp last modified date (in local time)
• General_Tagged_Date - Timestamp - tagged date
• Video_Format - Video Format (eg. AVC,VP8)
• Video_BitRate = Bit Rate (bits per second - only video content)
• Video_InternetMediaType - Internet Media Type (eg. video/H264)
• Video_Width - Video Width - Pixels
• Video_Height - Video Height - Pixels
• Video_FrameRate - Frames per second
• Audio_Format - Audio Format - (eg. AAC, Vorbis)
• Audio_SamplingRate - Sampling rat - hertz (eg.44100)
• Audio_Title - Audio title
• Audio_BitRate - Audio Bit Rate (bits per second)
• Audio_Channels - Number of Audio Channels
• Audio_Duration - Audio duration in miliseconds
• Audio_Encoded_Date - Encoded Date (Timestamp)
• Audio_Tagged_Date - Tagged Date (Timestamp)
• Json_full_exif - Full exif data extracted from the video (available as a json)

Our main engine for extracting file metadata is MediaInfo

Scene detection:

• Number of scenes detected
• Duration of each scene
• Average Scene duration
• Fingerprint of each scene

Template Matching

• Template name
• Closest distance to template in video
