#little problem rendering
3 messages in this thread
I'm having a little problem rendering on a ZEOS 486DX2-66 computer.
The set up is pretty standard DOS 5, 386-to-the-max, rendering to a
Targa-plus 16/32 card and recording to a Sony BVH 3100 using
Soft-VTR.
The problem is that I have to turbo down to begin the rendering
process. After the first step, more specifically after the first
file is loaded from disk, I can turbo back up to 66 and the rendering
flies. I'm not sure what this first file is but I believe it is an
overlay of somekind.
Also the same thing happens when I try to set up the vtr in turbo
mode. In turbo mode I get an error message, (opps I didn't write it
down). But turbo down everything works fine. During the rendering
and lay-off to tape the controller works fine after the initial turbo
down. The Soft-VTR controller works fine in turbo mode outside of
3DS.
It's not a major pain when I am present at the rendering but a real
pain for overnite work. Everything has to be rendered in slow mode.
Anybody have a suggestion.
You ought to check the bus speed as set in your BIOS. Bus speed is
set as a ratio of chip speed, and usually refered to as ICLK (= to
chip), ICLK/2 (1/2 chip), ICLK/4 (1/4 chip), etc. The standard for
the AT (ISA) bus is 8Mhz, and most adapter cards are designed for
that. My guess would be that your bus is set higher (like 12Mhz —
which I used to set mine to until a new hard drive I got had
problems). On the 66, you should still consider it a 33 for ICLK, as
the rest of the motherboard components run at this, and that is really
what counts — these new doubler chips just confuse things. So, a
setting of ICLK/4 = 8.25Mhz, which would be what you want.
Fred,
Please check the following: Reset your PC and go into the CMOS setup menu.
There is a menu item call "AT BUS SPEED" or something similar (this normally
appears in the Advance CMOS setup menu); check to be sure that this item is set
to "Standard AT BUS speed" or (8Mhz). Some PC vendors set this item to double
or triple the standard bus speed and this could cause the problem you
described. If you have further questions or comments please send me call me at
