### Technical Metadata

The Technical Metadata view displays information about each file (in either a CSV document or a table) including the file size, metadata from the <fmt > chunk, the existence of key metadata chunks, and file warnings.

Value Name | Description
--- | ---
FileName | In order to provide a concise presentation the filepaths are displayed from the directory path where the files diverge. Thus if two files are opened from /HardDrive1/videofiles/movies/videofile.avi and /HardDrive1/videofiles/spokenword/videofileB.avi then these will be displayed in the table view as /movies/videofile.avi and /spokenword/videofileB.avi since the /HardDrive1/videofiles section of the Filepath is common to the open files. The CSV version of the Technical Metadata view displays the full filepath to each file.
FileSize | The size of the video file in bytes.
Format | This value represents the type of container utilized by the file, including profile information. Example: AVI (OpenDML).
Duration | The total playing time, displayed in HH:MM:SS.mmm (hours, minutes, seconds, milliseconds)
Vid Format | The name of the codec used to encode the video data.
Vid CodecID | The four character code (fourCC) used by the AVI container to describe the video codec. This value is presented in ASCII characters. Below is a sample of compression codes:
dvsd | DV 25 Mbps
DV50 | DV 50 Mbps
H264 | H.264
IV30 | Indeo
JFIF | JPEG
LJ2K | JPEG 2000
MP41 | MPEG-4 Visual
v210 | YUV 10 bit
Vid FrameRate | The amount of frames per second intended for presentation on playback of the file.
Vid Width | The number of pixel columns within the frames of the video stream.
Vid Height | The number of pixel rows within the frames of the video stream.
Vid BitDepth | The number of bits of data per channel per pixel that the video data will decode to.
Vid BitRate | A measurement in bits per second for the video stream.
Aud Format | The name of the codec used to encode the audio data.
Aud Format | The two character code (twoCC) used by the AVI container to describe the audio codec. This value is presented in hexadecimal representation. Below is a sample of compression codes:
0000 | Unknown
0001 | PCM / Uncompressed
0002 | Microsoft ADPCM
0006 | ITU G.711 a-law
0007 | ITU G.711 Aµ-law
0011 | IMA ADPCM
0016 | ITU G.723 ADPCM (Yamaha)
0031 | GSM 6.10
0040 | ITU G.721 ADPCM
0050 | MPEG
FFFE | Extensible (used by Microsoft to provide a GUID as codec identifier)
FFFF | Experimental
Aud Channels | The number of audio channels encoded within the audio stream.
Aud SampleRate | The number of audio samples per second.
Aud BitRate | The number of bits utilized per second of audio.
Aud BitDepth | The number of bits of data per channel per sample that the audio data will decode to.
Tdat | Notes the existance of the Tdat chunk, either 'Yes' or 'No'. The tdat chunk is often used in Grass Valley and Adobe AVI applications.
INFO | Notes the existence of the INFO chunk, either 'Yes' or 'No'.
XMP | Notes the existence of the XMP chunk, either 'Yes' or 'No'. Right-click on this cell provides options to Import, Export, or Remove xml data. Doubling-clicking on the cell brings a text editor. Changes are not made until the file is saved.
aXML | Notes the existence of the aXML chunk, either 'Yes' or 'No'. Right-click on this cell provides options to Import, Export, or Remove xml data. Doubling-clicking on the cell brings a text editor. Changes are not made until the file is saved.
iXML | Notes the existence of the iXML chunk, either 'Yes' or 'No'. Right-click on this cell provides options to Import, Export, or Remove xml data. Doubling-clicking on the cell brings a text editor. Changes are not made until the file is saved.
MD5 | If an MD5 chunk exists, this column will show the stored value. This MD5 value is a checksum of the stream data only and does not include the file's metadata or any other chunk.
MD5 evaluated | If the MD5 is evaluated it will appear in this column. Any conflict between this column and the 'MD5' column indicates a change in the stream data portion of the file between the current evaluation and the stored evaluation.
Errors | Provides statements about potential structural problems with a given audio files: for instance if the RIFF size statement conflicts with the actual file size or if the audio files does not utilize padding bytes to follow odd byte length chunks.
Information | Used for status notes and technical information during operation.
