20,000 frames, and so on until the record is either finished or terminat-
ed.
Audio
If a record of audio is performed as well, at least one audio file will be
created in each video subdirectory which will match the length of the
video data stored there. In our mentioned example in section “Video”
on page 5-12 the audio file in the first subdirectory would carry the
name Clip_023_<Channels>-0000000.wav (if the *.wav for-
mat was selected). The last number in the file name is used to number
the audio files through the created subdirectories. Its amount of digits
depends on the number of digits set or determined for the video files.
The place holder <Channels> indicates the audio channels that were
selected for the record if individual mono/stereo files are created. Then
for each selected channel/channel pair one file will be created. If mul-
tiple channel files are generated, the <Channels> place holder will be
left out.
Multi-clips
Video and audio clips divided in several subdirectories are called multi-
clips. They are a necessity due to file system limitations of the operating
system, meaning Windows may cause problems if more than
20,000 files are stored in one directory. Whenever appropriate the DVS
software will create multi-clips automatically, for example, during the
finalizing of a project or when recording a clip with the I/O Tool.
To recognize multi-clips correctly a metadata file with the name Se-
quenceInfo.xml is created in the main directory of the clip. It details
the number of files per folder for this clip (see section “Path Options”
on page 5-19) and is required by the DVS software to enable a recog-
The file/frame numbering can be configured with the name
options items (see section “Name Options” on page 5-15).
Normally the count will start with 0 with the number of digits
for the frame number depending on the amount of frames to
be recorded. If no duration is specified it will provide seven dig-
its (24 h at 30 Hz = 2591999 frames).
If a container format is selected as the file format, the file will
be stored in the main directory, i.e. under Clip_023.
