Premiere 6.0 - rendering unaltered DV - why so long?

    Before we begin, let me just add that I'm relatively new to Premiere so am
    having fun discovering its quirks! However, here's something that's baffled

    I have a 118-minute project in Premiere, which consists of, basically, one
    long video and audio track with a few very small sections (2-3 seconds at a
    time, about 6 in total throughout the project) of video overlaid on top of
    the video track. I've selected the entire project and 'Rendered Work Area' -
    stepping through all the overlays are visible and correct.

    When I come to export to movie file, it goes at a not unreasonable rate up
    to the first overlay clip, slows down to render/output that, then slows down
    to a complete crawl for the entirity of the rest of the project. It would
    have taken about 8 hours to render the entire thing at that rate, so I
    aborted and searched for some options to change. I deselected 'recompress'
    in the output options but that made no difference. I can't see any more
    likely options, and the help file's useless! It's baffling because most of
    the project should be simple 'copy-and-paste' DV video so should not take
    more than about 2 hours to output, surely?

    Hoping someone can shed some light on this!

    You could try troubleshooting this problem using the
    Settings Viewer tool in Premiere ("Project" -> "Settings
    Viewer"). See this page for more information:

    It's baffling because most of
    You do not say what spec your computer is.

    It sounds like you need more processing power.

    Try splitting up your main DV file at the points where the overlays are.
    Use the razor tool and split the main file at the same in and out points
    as each overlay. Then try that.

    I've never had one huge clip on my timeline, always smaller sections of a
    clip or multiple clips, and I've not experienced what you are seeing.
    Could be an old bug.

    AMD Athlon XP 1600+ (1.4GHz)
    256MB SDRAM
    2x External 120GB Firewire HDD

    Not ideal, perhaps - could do with DDR RAM and plenty more of it - but
    the thing that bothered me was that, despite that, it was going at a
    good rate until it got to the first bit of overlay, slowed down to
    output that, but once it had got past that and back to the unaltered
    DV, it slowed to a crawl for the rest of the output.

    Had a look, but all the options mentioned here are ones I've tried
    fiddling with. Settings Viewer brings up no possible conflicts of
    format etc... so I'm still baffled!

    Ed. Are you trying to 'export as movie' ? ie making a complete avi file
    of your timeline. If so try export/print to video or export/to tape this
    avoids making the massive file if you are trying to make movie,

    I am indeed trying to output to a movie file. However I did try to export to
    tape and it got quite jerky for no apparent reason in unpredictable places
    all throughout the recording. I've de-fragged too and that made no

    Not something I'd thought of, but I'll give it a go and let you know!

    Nope, still exactly the same.

    Might it help to have a diagram of the offending timeline?

    Premiere gobbles up memory. Chances are that your system resources being
    used by background processes aren't leaving enough to avoid Premiere
    going into virtual memory mode.

    Try closing *everything* and running EndItAll before doing any video

    Curious... what effects have you applied to the audio?? Maybe it's trying
    to render that - depends on the effects I think.

    Do you have any hardware capture card that Premiere knows about, such as
    Pinnacle DVxxx, Matrox RTxxx ??

    The only audio effect I applied to it was 'Swap Left and Right channels',
    because the sound recording was made the wrong way round(!), but I made sure
    to 'render audio' before trying to export. That only took a couple of
    minutes, as I remember. But even so, since that's applied to the whole of
    the audio, there shouldn't be any difference as it moves along the timeline,
    should there?
    No, just a standard firewire card - 'Nisis Easycard Firewire' if it makes a
    difference (not that I expect it would).

    exporting fire your firewire card, try disabling other USB devices, then
    see what happens. USB seems to take precedence over firewire therefore u
    get break up of your video. There are some different solutions if your
    firewire card has a power socket on it then connect a spare lead from your
    power supply, if not, and to avoid opening the case, create a seperate
    hardware profile without USB devices on it in control panel/system./hardware
    use that solely for your DV work. It works for me anyway.

    Nope, logic dictates it shouldn't make a difference.
    OK... just curious because the capture card drivers sometimes cause
    problems themselves... but doesn't seem to apply in your case.

    OK how about, remove that first overlay you have and then export the
    movie. Does it still slow to a crawl at the same time code, or does it
    zoom right up to the next overlay?

    If it zooms until the first overlay, when happens if you remove them all
    (obviously making sure you don't save and overwrite your hard work! :)

    One more thing popped in my mind (it is not going to help
    in solving this particular problem but is related to the
    overall rendering speed, anyway): I have noticed that on
    my machine, exporting the timeline to a file becomes
    considerably slower if my DV camcorder is connected and
    switched 'on' on while processing. (I usually switch it
    off now whenever I export.) I guess this is because the
    PC has to spend some extraneous time on serving the I/O
    interrupts for the Firewire card, even if the camcorder
    is not actively sending a picture.

    Ive had problems with Premiere and my camcorder turned on too, you may
    have a good point there.

    True, 256MB might not be quite enough for video work...
    That's exactly what I've already done! Thanks for the suggestion though.

    I've given it a try, but it doesn't seem to have made a single difference.
    My firewire card doesn't seem to have a power socket on it, and disabling
    the USB devices didn't change a thing, unfortunately.

    It crawls right from the begninning to... well, I didn't quite have the
    patience to sit there for very long, but after 5 minutes it was barely past
    the 2 minute mark on the video...!
    Tried this too. Crawls right from the beginning again.

    This is really getting very baffling now. I'm either going to have to find a
    solution or leave it for 8-9 hours to export properly (not entirely
