Video Capture: Compatibility with Hard Drives & CD-ROM Drives
Contents:
HARD DRIVE COMPATIBILITY
A data rate of at least 1.4 MB/sec is recommended for capturing digital
video.
Note: .AVI files are large, a high capacity hard drive will be needed
if large .AVI files are going to be created and stored.
The following table provides a list of hard drives and their
compatibility with the Intel Smart Video Recorder and Intel Smart Video
Recorder Pro.

DROPPING FRAMES WITH FAST 32-BIT SCSI ADAPTERS
Symptom
In systems with fast 32-bit enhanced SCSI adapters, up to 50% of the
frames are dropped when video is being captured at 160x120, 30fps.
Description
Frame dropping occurs when SMARTDRV.EXE loads the double buffering
utility in the CONFIG.SYS file. SMARTDRV will then slow down some
system functions, including video captures.
Solution
To prevent fast 32-bit SCSI systems from dropping frames:
Remove SMARTDRV.EXE from your CONFIG.SYS file.
OR
If you need SMARTDRV.EXE for double buffering, capture some video at
320x240 before doing your 160x120 capture. SMARTDRV will adapt to the
needs of the 320x240 capture and will capture subsequent frames (until
the computer is rebooted) correctly at 160x120 and other resolutions.
Note: By default, Windows copies SMARTDRV.EXE into both the
CONFIG.SYS and the AUTOEXEC.BAT files. This allows SMARTDRV to use less
conventional memory. The SMARTDRV in the CONFIG.SYS takes less space and
doesn't become active until it's executed by the AUTOEXEC.BAT file.
However, SMARTDRV will run fine if it's only loaded in the AUTOEXEC.BAT.
The only reason SMARTDRV needs to be in both the AUTOEXEC.BAT and
CONFIG.SYS files is if you have an older SCSI drive that needs double
buffering.
CD-ROM DRIVE COMPATIBILITY
Most CD-ROM drives on the market will work with the Intel Smart Video
Recorder and Intel Smart Video Recorder Pro.
You cannot capture motion video on a writeable CD-ROM drive, because the
data rate of the drive is too slow. A data rate of at least 1.4 MB/sec
is recommended for capturing digital video. Check with the manufacturer
of your CD-ROM drive for more information.
The following table provides a list of CD-ROM drives and their
compatibility with the Intel Smart Video Recorder.
