MA>> I currently own a dc1tv card and your software. I have'nt used it much yet
though.
Hope you will like it. May I ask which our product they bundle with and what
version?
MA>> My question is what resolution and frame rate are you capturing for your
demonstrations.
I captured all clips in 320×240 30fps using miro's M-JPEG codec for that demo.
Sometimes I capture them in a slightly larger size (328×248) and crop the
border out to remove noise at the edge. I use a comercial VHS tape release
from our gevernment about Chinese foods as my source. After capturing and
editing, I print to video and also capture it to tape. I play the source to
compare with my result side by side on two TV sets. I found there is little
degration in video quality. But if I play the source and my result alone one
by one, nobody can tell which is from the source tape and which is my work. I
also found 320×240 30fps clips with "Zoom by 2" option of the Media Player turn
on give me similar result on computer monitor for general usage. Most of the
time when working on machines without a good M-JPEG board, I create AVI using
Cinapak codec because it always gives me good result in playing back.
MA>> I have a similar setup to yours (Pentium 90, 16 meg ram, Diamond Stealth
64 video card) and I would like to know what type of hard drives do you use?
I encountered lots of problems in using Pentium/60 machines with various boards
(including miro DC1 board), we can't even compile programs on them because it
will hang. After I switched to Pentium/90, all problems are gone. If you want
faster effects and editing, you may consider to add more RAM. If you do
capture and play back most of the time with simple editing, then that's more
than enough. I use two Micropolis 1.7G AV disks for each machine. There are
3G/4G disk from Micropolis and Seagate are rolling out 2G/4G/9G drives,
however, they are too expensive. The 1.7G drive has the best price at that
time.
MA>> I have a Micropolis 1936av scsi with a future domain pci scsi adapter.
I think this is the same disk that I connect to my Adaptec PCI SCSI card.
MA>> I have'nt connected all the components yet and I'm wondering if there is
anything special I would need to do as far as the scsi drive is concerned. I am
also running windows for workgroups.
I think you will not have big problems in doing that. Turn disk cache off (and
32-bit file access in WFWG) when you do capturing because it will slow you down
in transferring data to your hard disk. If you like, turn disk cache back on
when you do editing. If you don't do that, a litte bit more disk access will
happen.

PS: you may encounter this in WfWG 3.11 since you're dealing with big files
now.

SYMPTOMS
========
When you try to open or copy a file larger than 2 megabytes (MB), you
may receive one of the following error messages:
Segment Load Failure
-or-
Insufficient Memory
CAUSE
=====
These errors occur if both of the following conditions exist:
– You are using a permanent swap file without 32-bit disk access
enabled. This causes paging to occur through MS-DOS.
-and-
– You are using 32-bit file access. Since 32-bit disk access is
disabled, the real-mode mapper (RMM.D32) is used to provide 32-bit
file services.
These errors do not occur if the permanent swap file is on a drive with
32-bit disk access enabled or if 32-bit file access is disabled.
WORKAROUND
==========
To work around these errors do one of the following:
– If your hard disk controller is WD1003 compatible, enable 32-bit
disk access.
-or-
– Disable 32-bit file access.
STATUS
======
Microsoft has confirmed this to be a problem in Microsoft Windows for
Workgroups version 3.11. We are researching this problem and will post
new information here in the Microsoft Knowledge Bases as it becomes
available.
MORE INFORMATION
================
This size of the file needed to trigger this error is not always 2 MB.
The limit is 512 multiplied by the size of the allocation unit for the
drive where the target file resides. The allocation unit size is commonly
4096 bytes, thus the apparent 2 MB limit. In cases in which the allocation
unit size is different, the limit is also different.
