Genlocking- The
Vision/VisionPro are now capable of genlocking. Which means that the output
timing exactly matches the input timing. This has the benefit of never dropping
a frame of video and also serves to slightly minimize lipsync delay. As it was
not originally designed to do this we had to compromise the SMPTE standard crt
timings slightly--this shouldn't be a problem for the most part but there is the
possibility it may not work with some displays (haven't seen one yet). If
genlocking doesn't work simply turn it back off--don't feel too bad as it is
very hard for most viewers to spot a frame drop since they occur infrequently
and a frame accounts for ~1/60th of a second..
To enable
genlocking the output frame rate should match the input. So if you've got an
NTSC input the output rate should be set to 59.94 Hz and if you're using PAL is
should be 50.00 Hz. Genlocking defaults to off so you also need to turn it on by
pressing "menu",0,9,8,1 on the remote. You can check the status by
pressing "menu",0,9,8,2. If it doesn't work on your display you
can turn it off by pressing "menu",0,9,8,1 again.
Sidebar Pan- If you spend much time watching
material where the aspect ratio creates sidebars you should probably
enable this feature to avoid burn-in of your display. When sidebars are on the
Vision/Pro will very slowly move the display back and forth. You can toggle it
on/off by pressing "menu",0,9,8,7 on the remote.
Deinterlacing bug fix- under some situations the
Silicon Image chipset would get stuck in "film" mode which can result in
occasional combing with both DVD's and video.
New Output modes- (users who
use only one output resolution will not find this of interest) Prior to this
release the output mode has been tied to the input and since there were 2
memories per input you could define 2 output configurations per input (you would
need to change the output mode to independent to do this). New to this releiase
are 2 output modes called "VRES" and "VRES A/B". In a "VRES" output mode you
instead have up to 16 output configurations which are selected independent of
the input. In a VRES mode switching to a different resolution recalls the preset
configuration for that resolution instead of setting a factory default output
configuration. So, for example, if you switch to 720p for the first time you get
a factory default 720p as you do in a non-VRES mode. You might then make some
adjustments to it and switch to 768p. Now if you switch back to 720p you'll get
your adjusted configuration you had set up earlier. In "VRES A/B" you have 8
output configurations for MemA and 8 for MemB and the output automatically
switches between MemA/B on an NTSC<->PAL input signal change. So, for example,
this allows you to have two 720p output configurations which could be manually
switched between by pressing MemA/B or automatically as mentioned before.
There
is also a new output reset command to go along with the VRES modes.
Pressing "menu",0,9,9,8 will reset the current output configuration to
the factory default for that resolution.
More Status information-Previously if the menu was
not onscreen pressing the ok (or enter) key would report the current input and
zoom level. Now by pressing the enter key additional times you can cycle through
more status information such as resolution, refresh rate, output type, genlock
status, and sidebar pan status.
Gamma correction precision increased- For
calibrating the color-of-gray the precision has been increased 10x. This is
found in the menu under IN->COLR->CTMP (note: you need to enable the service
menu by pressing "menu",0,9,1,0 to enable the presence of this menu item).
Per aspect sharpness settings- Previously sharpness
was set per input memory. Some users expressed a preference for different
sharpness levels depending on the input aspect. Now after setting the sharpness
you have the option of setting it for all input aspect ratios or just the
current one.
Output size & position improved- These were
previously limited more than necessary and would sometimes unnecessarily
interfere with one another.
