i currently have a pentium 200 mmx with 144 mg edo ram, a quantum 6.4 gig
udma33 drive with two 2 gig partitions free for video capture and
editing/rendering, a tyan s 1573 atx-2 tx chipset motherboard, windows 95
osr 2,the mystique 220 with the rainbow runner. i am also using the tyan 32
bit bus master drivers for the hard drive. the matrox hard drive benchmark
usually reports about 3.5 mg/sec as the rates for each partition of the
hard drive, although in the past it was rather strange and reported either
about 2.5 mg./sec or about 21 mg/sec when i tested the drives repeatedly.
this seems to have stopped lately.
i have set up the computer for editing with the usual suggested changes to
the read ahead, write back, screen savers, clock, desktop computer settings
to improve performance.
my main interest is outputting to pal svhs and vhs videotape and also to
ntsc vhs videotape. i have pal and ntsc svhs camcorders and pal svhs vcr
and an ntsc vhs vcr. my experience is in analogue video editing with two
vcrs and controllers etc.
i am not totally pleased with the performance or visual results that i am
getting from this system. on captures i get dropped frames sometimes ( at
compressions of about 9:1 and audio at 22khz and 16 bit mono)and on
playback i get frozen video sometimes. if i turn the compression down to
get better captures (to about 13:1) then the visual quality of the
resulting edited tape is a bit grainy. i use premiere 4.2 and media studio
pro 5.01. the preview and rendering times are somewhat slow as well.
my questions are about what should i do to get better results in captures,
playbacks and final visual quality.
1. should i get a better capture card? i am looking at the av master or the
edit bay or the broadway beginner, but i hear that the av master has
compatibility problems with the tx chipset motherboards and the broadway is
not really intended for output to videotape. which card is the best quality
and the most compatible with my motherboard?
2.should i get a uw scsi av drive and an adaptec 2940uw controller to use
for video capture and playback, or are udma 33 drives good enough now?
should i get a separate udma 33 drive apart from the one i already have?
3. should i dump the tyan busmaster drivers and use intel ones or none at
all? i have been told that i should be getting more than 3.5 mg/sec rates
from my hard drive and that maybe the tyan bus masters are at fault. or can
i do anything else to improve my current system? am i just ignorant about
the quality and performance possible with this price range of cards
($500-$1000)? i cant really justify going to cards that cost several
thousand dollars as i am just a home movie hobbyist.
i really want to make this work but i am getting frustrated with the lack
of intelligent advice and support from all the vendors.
thank you for your help
