2.7 About Timecode / Frame Number Fields
The DVS software provides various fields where data in timecode for-
mat is provided or an entry in such a format is necessary. The timecode
format is hh:mm:ss:ff (hours, minutes, seconds, and frame num-
ber).
Drop-frame Timecode Indication
The last colon of the timecode format may be displayed in the software
as a full stop. Then the timecode fields of the software will display, for
example, 12:25.07 instead of 12:25:07. This indicates that the
drop-frame timecode feature is activated. When entering timecode, the
last colon can also be replaced by a full stop. Further information about
drop-frame timecode can be found in the “CLIPSTER Configurations”
user guide.
Higher Frequencies and Timecode Format
Additionally, an asterisk may be added to the timecodes of the DVS
software (e.g. 12:25:07*). This will be the case when the video ras-
ter’s frequency exceeds 30 frames per second because the original
timecode format is limited to frame rates as high as that. To account for
video rasters with higher frequencies (e.g. 720p at 60 Hz) one time-
code number is used for several video frames, meaning every second,
third or fourth timecode provides the same timecode (frame) number
but is tagged with an asterisk to mark it as repeated. The standard time-
codes that will be used for such procedures are 24 Hz, 25 Hz and
30 Hz: For example, a video raster frequency of 48 Hz is provided with
a 24 Hz timecode, while a 60 Hz frequency receives a 30 Hz timecode.
This will result in a doubling of the timecode numbers:
At even higher frame rates (e.g. 90 Hz) the timecode numbers will be
tripled, quadrupled etc., making a timecode handling of all common
frequencies possible.
