The conversion utility supports the standard Windows file formats .jpg, .bmp, .tga,
and .tif. It also supports 8-bit and 10-bit .yuv files from the DPS Hollywood.
Single still image files in the above formats are converted to 8-bit .dst files (for use
with the linear keyer) or 10-bit .dts files (for use with the test signal generator) for the
DPS-475/575.
When converting to .dst, any alpha channel information stored in the source file will
be used for the DPS-475/575 keyer. If a source image is too large (greater than
720x486 NTSC, or 720x576 PAL), it will be cropped. If a source image is smaller
than the screen size, the unused area will be treated as transparent by the keyer. If a
10-bit Hollywood .yuv file is converted to .dst, it will be down-sampled to 8-bit, and
the extra resolution will be lost.
When converting to .dts, any alpha channel information in the source file is lost. 8-bit
image formats such as .bmp can be converted to 10-bit .dts files for use as test
signals, but no additional resolution will be gained. Ideally, 10-bit Hollywood .yuv
files should be used as the source of .dts files, for maximum quality.
Animation files for the DPS-475/575 (.dan files) are created from a numbered
sequence of image files, all of which must be stored in the same directory. For
example, anim0001.tga, anim0002.tga, and anim0003.tga would be converted into
an animation file named anim.dan. At least one leading zero is required in the
naming convention of image sequences (i.e. anim1.tga, anim2.tga, anim3.tga is not a
valid sequence). When selecting the source files to be built into an animation, it is
important to add only the FIRST image of the sequence into the Files to Convert
list. In the above example, only anim0001.tga would be selected for conversion; the
rest of the sequence would be converted automatically.
Still image files with a filename ending in a number (such as image0003.tga) are
assumed to be part of an image sequence, and are converted to .dan animation files.
All other still image files are converted to .dst stills.
The following chart summarizes the source formats recognized by the conversion
utility, and the formats to which each can be converted:
SOURCE DESTINATION
.tga (single image) .dst, .dts
.tga (numbered image) .dan
.bmp (single image) .dst, .dts
.bmp (numbered image) .dan
.jpg (single image) .dst, .dts
.jpg (numbered image) .dan
.tif (single image) .dst, .dts
.tif (numbered image) .dan
.yuv (single image) .dst, .dts
.yuv (numbered image) .dan
.dts .tga, .bmp, .tif, .jpg, .yuv
.dst .tga, .bmp, .tif, .jpg, .yuv
