harddisk recording with MiniDV in the field

Archived from groups: rec.video.desktop (More info?)

Hello All,

I'm fairly new to digital video and after recording a stage play the
other night, I'm about to capture about 6 hours of material.

I was hoping to find a solution to capture faster than realtime, but
have learned this is not possible with the MiniDV system.
(If I'm wrong, please tell :))

So, I've been looking around for a faster method of shooting/capturing
and found JVC's DR-DV5000 camcorder (price around 6000-7000 euro)
which can be equipped with a hard disk unit to shoot directly to HDD.
Awesome!

Only, I've got MiniDV money (if any money at all ;)....
After browsing Google for a while, I've only found 'solutions' which let
you shoot directly to HDD if you attach the camera to your PC using your
MiniDV camera...

I've been searching all over the internet this night to answer this
question:

Is it possible to shoot directly to a HDD using any MiniDV camera 'in
the field'?

Anybody?

Thanks!

Tim

    As long as the miniDV camera has a 1394/firewire port and the laptop has a
    port as well, you can do this. I used to record direct to hard-drive doing
    multicamera shoots and running the output of the switcher to a miniDV camera
    which, in turn, was connected to my laptop. It worked fine.

    Bear in mind that miniDV requires a little over 13 gigabytes over storage
    for an hour of video.

    That's starting to get interesting. But don't all DV cameras require a
    tape running to operate? I don't think my Optura Pi will do anything
    without a tape.

    I recently wore out the first few minutes of a DV tape, because I was
    rewinding & replaying it to solve a computer/capture problem. (Yes,
    next time I'll stop & restart, if possible). I thought back to the
    Sony Mini_DV videocam I had a few years ago - it had some interesting
    ideas and advantages, but too many shortcomings to live with in
    regular use. My son recently visited, with a Sony mini-DVD videocam -
    again, very interesting but the resolution (& perhaps some other
    specs) were not enough to tempt me to go that way yet.

    What I'd like to see is a good-quality camera/storage box solution,
    i.e. with the storage & battery on your belt and the camera separate.

    Not quite. My Sony DCR -PC101 does not. If I go to the VCR mode I can
    switch the Firewire port on. I use this to capture TV. The only tool
    that supports streaming to the PC though is DVIO.EXE (google for it, its
    freeware).

    Hi!

    Thanks for the replies.

    In fact this is the same system (FireStore FS-3) that I was referring
    to for JVC DVCAM camcorders! :)

    Can't believe I was so close and couldn't see...

    Anyway, thanks for the eye-opener and let's wait patiently till december
    before getting this little gem for about 800 dollars.

    If the Firestore products from
    http://www.focusinfo.com/products/firestore/firestore.htm don't interest
    you, take a look at http://www.nnovia.com/
    Some folks like it a lot better - and it's a bit cheaper as well.

    Thanks, Mike. I think my problem is that I'm OK understanding the
    HD/DVD/storage end of things, but don't know the camera options well
    enough. I'm pretty sure my Optura Pi needs to have a tape running
    while shooting, which is what I'm trying to avoid. Could any camera
    that does pass-through record to a Firestore or QuickCapture without
    running a tape, or do we need some prefessional-level camera for that?
    Suggestions?

    Excellent question John. I think, for the definitive answer, that you'd
    have to ask the individual manufacturers.
    In the Firestore review at
    http://www.digitalproducer.com/articles/viewarticle.jsp?id=26845 the
    reviewer specifically says that tape is necessary. However, the same guy
    reviewed the Nnovia at
    http://www.digitalproducer.com/articles/viewarticle.jsp?id=25508 and didn't
    mention it (unless I missed it).

    Well.. I heard that the XL1 will stay on and pass through if the tape door
    is left open. Never had the courage to try that though.. My instinct is to
    have it open as short a time as possible..

    I have never used any of these hard-disk units, but I have some
    knowledge that could be of interest.

    My experience is the following:
    A switched-on DV camera in "camera mode" will transmit a video signal on
    the firewire port at all times.

    However, only with a tape running will the DV frames included proper
    timecode.

    And timecode is something you will definitely want when it comes to
    editing..

    It is possible (and perhaps some units do it) to "synthesize" the
    timecode and let the hard-disk recorder insert valid timecode into the
    DV frames before writing to disc.

    I do this myself in a special computer application. I never have any
    tape in the my cameras, but record to computer hard disk.

    This is very interesting, Johan.
    Is this 'special application' a commercial product, or you wrote it
    yourself, or what? Could one run it in a notebook PC and record to its
    HD?

    The answers to both questions is yes, meaning that I wrote it myself,
    and it is (or rather on its way to become) a commercial product.

    However it isn't just a "capture application" (it does much more), but I
    know how such an application could be written, and (given satisfactory
    disk performance) it should run nicely on a notebook PC.
    The CPU load when just capturing DV is very low.
    My application captures several DV streams in parallel.
    It's the preview (if you want it) that costs...

    Can you give us any hints as to when we might expect to see this app or who
    will be marketing it? Any news releases to whet our appetite? If you're
    under an NDA, I understand.

    Thanks!!
    Currently you can only record one stream at a time to a hard drive. What
    folks here and elsewhere have been looking for/hoping for a long time is
    something that would allow the recording of multiple DV streams (3 would be
    nice) simultaneously to a single hard drive. Editing would be done in post
    as there are numerous NLEs that allow this. A device like Newtek's Toaster
    functions like a video switcher but a lot of us would like to be able to
    make those decisions in post.
    Is this feasible with what you have in the works? Thanks.

    Yes, as a matter of fact it is (in a way...).

    But I'm doing it for a special purpose right now and that is sports
    analysis.

    I use several DV cameras to record an athlete from various angles, and
    normally I do it in two steps
    1. Capture the DV streams to memory.
    (It is normally only a few seconds, each stream consumes 3,6 MB per
    second and memory is cheap these days....)
    2. Write out the data to disk (or discard after replay from memory)

    For (2) I have used both AVI and "raw DV". (and also a proprietary format)


    I assume that for the kind of application that you have in mind, this
    two-step approach would not be applicable. (Assuming you want to record
    for longer periods)
    However, from what I have learned during my development work, I believe
    that it would be quite easy for me to write multiple DV streams directly
    to disk.
    Of course, you need a disk with good enough capacity to handle the data.
    Notebook disks are sometimes (or even often..?) to slow for this.

    My "two-step" approach solves the problem with disk performance, since
    actual disk-writing doesn't need to be done at real-time speed.
    Tests show that on a notebook, typically 1 stream will write *faster"
    that real-time ( one 5-second stream writes i 3 seconds), but more than
    1 will be slower (E.g. writing three 5-second streams will take 20
    seconds). This suggests to me that such a computer will not be able to
    handle more than 1 stream for live-to-disk multiple capture.

    I do have a setup (3 DV cameras) up and running on my desktop right now,
    so I can give it a quick try in the upcoming days....
