Syncro
Scan Is used to prevent black or white horizontal bars that may appear across
your computer monitor or television, when you are recording a scene that has either of
these in it. By setting up the correct syncro scan in the menu, you can press the shutter
button on the side of the camcorder and prevent this problem.
What you are doing in the MENU, is trying to synchronize the camera's shutter with the
scan rate of the computer monitor or television included in the scene.
Aspect Conversion
The standard images have an aspect ratio of 4:3. When placed in 16:9 aspect ratio the im-
ages are recorded with black bands across the top and bottom of the screen creating the
16 by 9 or letter box image. This method is called letterbox and has the major advantage of
WYSIWYG (What You See Is What You Get). It you use an external anamorphic lens
adaptor, about 25% higher vertical resolution can be obtained which may be more important
for film out applications. If Letterbox is selected, the normal CCD based imager signal out-
put of 720 pixels H by 480 pixels V is cropped down to 720 pixels H by 360 pixels V. The
remaining 60 pixels at the top and bottom of the picture are forced to black. When an exter-
nal anmorphic lens is used the source image is optically converted from widescreen 16:9
aspect down to a 12:9 aspect (4:3). Therefore the entire surface of the CCD based imager
can be used to capture the image, yielding a full 480 lines of vertical resolution.
Color Bars
A SMPTE test signal is generated internally, used to check the cameras per-
formance, it also may be used at the beginning of the videotape as a reference.
You can turn this function off or on in this menu. If you leave it on, it will shut off when the
camcorder is placed in the VCR mode or the power is shut off. This function does not work
in the progressive mode.

the default setting for the DVX-100. Digital Video uses 0% setup (which is the
ITU-R-601 Digital standard setting and Standard analog interlace video uses 7.5%.
