I wonder if anybody can help me out with a problem I'm having when
capturing miniDV video directly to mpeg2 using Ulead Video Studio 7.
I have an HP a350n pc, which uses a P4 2.8c cpu, 512Mb of pc3200 RAM,
and I have two 160Gb 7200rpm hard drives installed. DMA is enabled. I
take care to run the absolute minimum of programs, with antivirus and
other utilities disabled. Task manager typically shows 26 processes
running.
I find that the DV transcode buffer fills up and has to flush after
only about 4 minutes of video capture from my JVC miniDV camcorder. It
takes about 3 minutes to flush 2727 frames. Using task manager, I can
see that the cpu is working at about 85%.
I know that I can import footage as avi files without any problems,
and then transcode that to mpeg2 separately. I have discovered,
however, that the finished video quality taking that course of action
is actually slightly inferior to that obtained using direct mpeg2
capture, even using identical best quality settings. In particular,
there's noticeably less anti-aliasing on rapidly moving sections for
the direct-to-mpeg2 footage.
I'm trying to capture at the highest quality, using variable bitrate
set to the maximum DVD compliant 8264Kbs, with the quality slider in
the video capture properties dialogue box all the way over to the
right. Setting it to constant bitrate doesn't change things much - I
can still only capture about 4 minutes of video before the DV
transcode buffer has to flush. The disruption shows up on the mpeg2
video, too, and I don't like to have my camcorder on pause for any
extended period of time.
My hard drives have plenty of free space, and I keep them defragged on
a regular basis.
If I set the quality slider to the left, it does capture for longer,
but I find the resultant video quality unnacceptable.
Any ideas on how I can extend my capture time?
Thanks in advance for any advice offered,
C Toast
