Audio Ref Status
Note: This section will not be present except in a system with Merging Technologies Audio hard-
ware, e.g. a Mykerinos card.
Audio Ref The field shows the Audio Sync Reference Source selected Currently. Use the drop-down
list to choose the source. The choices available will depend on the VCube version and the
hardware available for example:
Internal (Mykerinos clock)
Video Input
Wordclock Input
Audio Input (lists all available digital audio inputs e.g. AES/EBU. VCube will check each
channel for a valid signal and lock to this.)
TC Clock Ref The field shows the TimeCode Sync Reference selected Currently. Use the drop-down list
to choose the appropriate source.
Show Mykerinos Settings Tab
Note: This button will only be available when a Mykerinos card is fitted. Composition Audio For-
mat
Sampling Rate The field show the current Audio Sampling Rate. Use the drop-down list to choose the
Audio Sampling Rate (Contents of the list will depend on the hardware (if any) and the
VCube version. E.g. a system with a Mykerinos with AES/EBU daughter card will accom-
modate anything from 44.1kHz to 384kHz
Composition Video Format
This section determines how the video signal is displayed.
Note: that the all the possible settings supported by the computer graphics card are not sup-
ported by the video card. If an unsupported setting is selected a warning message will be dis-
played on the video output.
• Please see: Video Formats and Bandwidth on page 232 in the Appendices to find the correct settings
for your specific needs.
• Any Format conversion required is applied to the entire Composition including resized Layers on both Pre-
view and Video outputs.
Width Enables Width in pixels to be trimmed for the Composition.
Height Enables Height in pixels to be trimmed for the Composition.
Field Order Offers the choice of whether Upper or Lower Field is displayed First when interlaced or
None if the Media is formatted as Progressive Scan.
Pixel Aspect Ratio The field show the current Pixel Aspect Ratio This is the shape of the individual pixels. HD
video systems mainly use a square pixel with aspect ratio of 1:1. NTSC uses an aspect ratio
of 0.9:1 resulting in a 648 x 480 display. NTSC 16:9 uses an aspect ratio of 1.2 resulting in
an 864 x 483 display. PAL uses an aspect ratio of 1.07 resulting in a 768 x 576 display. PAL
16:9 uses an aspect ratio of 1.42 resulting in a 1024 x 576 display
Note: Anamorphic Wide Screen formats do not use a greater number of pixels to produce the
picture. It is the Pixel aspect ratio which determines the shape of the frame. (Assuming the cor-
rect flag is set.)
