  1. Why? on 5GB Hard Disk On A PCMCIA Type II Card · · Score: 2

    I can't figure out why Toshiba is bothering with Type II PCMCIA. A 5GB Type II CF card would be very cool, and would have some serious utility, but there just aren't that many devices that have full-size PC-Card slots that need removable online storage like this.

    Not to mention the fact that 16x DVD drives are all over the place...

    Fine. 16 x 10Mb/s is still only about 6x DV, and you're limited to about 20 minutes per DVD, so you're changing media about three times as often to boot. I just can't see how it's worth archiving DV on DVD-ROM.

    A great point - however if you are doing editing/post with this DV, pulling it off the miniDV tapes everytime you need something would be a pain. Storing a series of raw scenes on a DVD-R would let you keep all the data online, but not taking up your hard drive.

    Probably not worth it, really. DV is 25Mb/s, DVD is 10. So you need at least a 4xDVD-ROM for DVD-R to be any faster than DV. The fastest DVD-ROM read speed I've seen is 10x, and you know that these speeds are peak, just like a CD-ROM drive. So we triple the media cost, spend time burning DVD-ROMs, and get, at best, a 4x speed improvement when it comes time to go get the footage again.

    There are better ways. Keep your video on tape, log your footage carefully, and then keep the logs online and the tapes on the shelf. Batch capture works so well on modern NLEs that you can just feed the tapes in and let the machine do the work.

    There's actually a very good reason why video and tape go hand in hand. Tape is excellent at capturing data with moderate bandwidth for extremely long durations. Sure, random access is cool, but video is by nature sequential.

    DVD-RAM specifically is a brain-dead standard. Sure, Hitachi has a camcorder that records directly to (3") DVD-RAMs, but then Sony has a camcorder that records directly to MD-Data2 and that's not going to go anywhere either.

    But what you're looking for is DVD-R, and subsequently DVD-RW.

    The drives are shipping now, though Apple is consuming 100% of the supply. The drive in question is the DVR-103/DVR-A03, and it can record DVD-R and DVD-RW. Compaq will be shipping the drives soon, and you'll also start seing them in external FireWire enclosures in the next couple of months.

    To your specific questions:

    All I want to do is dump and/or mix raw mini-DV footage from my digicam onto recordable DVD media.


    Remember that DVD-Video is MPEG2, and DV is not. (DV is more closely related to a series of JPEG frames) This means that there will be substantial encoding time if you want to make these discs playable in set-top DVD players.

    If all you want to do is archive the DV footage...leave it on the DV tapes. DVD-Rs have only now come down to $10 for a 4.7GB disc, while MiniDV tapes are about $6 for 13GB of storage. I don't know anything about the archival characteristics of DVD-R media, but tape is a known quantity, and since it's digital, you can "refresh" your archive periodically.

    Better yet, I'd like to be able to take that little DV tape and load it into a mini DV drive (is it 4mm DAT?) on my DVD system, and shoot more movies while I'm saving footage to DVD media.


    You still have the encode time issue above. MiniDV is not 4mm DAT, but Sony does (did? I keep seeing closeouts) make a deck that fits in a 5.25" drive bay. It's called the DRV-100. Internal or not, the interface is still Firewire, so you're better off with an external deck.

    I'd also like to make backups of my VMWare guest OS virtual disks to DVD.


    No problem. The drive is also a CD-RW machine, so it's a "small matter of software" to get it working burning DVD-ROMs. Toast is already there on the Mac.

    The "smart home" folks who do this for a living refer to this as "structured wiring," so that's probably the right search term.

    2x 4pr CAT-5
    2x RG-6 (75ohm Coax)
    2x 1pr 16ga speaker wire

    This whole bundle sells for about $2/foot in 500' reels, which is about a house worth of wiring. If you're going to put cabling directly in the walls (as opposed to the excellent suggestions for going with conduit) then this is the stuff to use.

    Given the installed infrastructure, I think emerging technologies are going to be centered around getting more speed out of CAT-5 and MMF. Heck, my new G4 has a 1000Base-TX port...CAT-5 again.

    Myself, I'm cheap. So I've just been running 2xCAT-5 and 2xRG-6 everywhere I go, more if I need it. I live in a single-story house with a crawlspace, so it's easy to go below and pull more wire if I need it.

  13. Passes with flying colors... on Record HDTV To A FireWire DV Deck · · Score: 1

    No problem.

    First of all FireWire is 400Mb/s. Yes, you can run full, uncompressed SMPTE270 video over FireWire.

    The worst-case broadcast bit rate for HD is 19.4Mb/s. HD is broadcast as MPEG2, so it is compressed up the ying-yang. So is Digital Cable/DSS. That 270Mb/s D1 tape gets squashed to 2-6Mb/s for that "Digital Picture" we pay so much for.

    DV is usually 25Mb/s. (I say "usually", Panasonic DVCPRO has bit rates up to 100Mb/s, but that's somewhat non-standard)

    My impression of the 16 9 Time product is that it encapsulates the HD bitstream in DV frames. A clever hack to be sure, but it's enough to make the DV decks happy.

    As to doing data backup to your DSR-20, remember that tape has dropouts. You'd need to do a fair bit of FEC to make that backup useful. Also, the nature of video is such that all the design decisions for DV were made in favor of isochrony over data integrity. Better to let some blocks through than freeze for a few frames. This has been gone over here before, as well as on the linux1394 discussion lists.

  14. HD MiniDV isn't limited by the encoder... on Record HDTV To A FireWire DV Deck · · Score: 1

    First of all, all of these devices are recording the compressed stream, not doing reltime encoding. This works just like the once-and-future DVHS decks, and the Panasonic PV-HD1000 would happily record HD MPEG2.

    Camcorders are a different problem, and Apotsy is quite correct that realtime MPEG2 is harder than the DV codec, which is essentially JPEG with some interleaving to distribute tape dropouts.

    That said, realtime MPEG2 is very real, and has been for some time now. In recent memory, realtime MPEG2 was expensive ($50k and 2RU in '98, $5k on a PCI card more recently) but Sony has recently released a MiniDisc camcorder that does MPEG2 encoding. MSRP is $2499, but the first MiniDV cameras cost that two years ago too.

    The reason you won't find HD MiniDV anytime soon is that until the HD sets break out of the volume/price chicken-and-egg problem, you won't be able to sell HD cameras, because nobody will have anything to watch the tapes on.

    The 16 9 Time hack is beautiful because it produces a relatively open bitstream. But the Hollywood/Tokyo axis has another round of DVHS players coming...you thought DIVX was bad, wait until you get a load of DVI/HDCP.

  15. But out here in the real world... on Record HDTV To A FireWire DV Deck · · Score: 1

    REAL HD is limited to 19.4Mb/s for broadcast, because that's what the 8VSB transport can carry. Uncompressed HD can be ungodly huge, but that has nothing to do with broadcast or CATV, only studios and post.

    As you point out, uncompressed SD is 270Mb/s, but remember that REAL SD is 6MHz wide, and you're not going to tell me that AM and ColorBurst gets you 45 bits/Hz.

    You broadcast guys should pay attention to what happens when your signal leaves the studio. It's a jungle out here.

    OK, so I'm completely spoiled by the empeg and empeg's other product, the Rio/Dell Receiver. But the bottom line is this thing sucks. The UI is slow and often can get behind what's actually happening, so it will show one track title while it's playing another. The desktop software is entirely adequate for managing a 64MB flash-based player that might hold all of twenty tracks, but just doesn't cut it for a player that could hold two thousand. You have to add files one directory at a time (no drag-and-drop of /home/mp3) and I had a bunch of problems that make me think you can't have two tracks with the same title on the player at the same time. It takes an eternity to boot, and the boot time gets longer as you add more tracks to the drive. You can easily kill a set of batteries just carrying it in your bag, since the "lock" switch is read by software. The offshoot of this is that it boots up half-way, reads the lock switch, and shuts down. The audio quality is mediocre, and the headphone drive is pathetic, even before you turn on EAX. Trying to use any of the EAX (DSP) features will cost you about 10dB of volume, which makes headphones unusable without an external amp. To be fair, some of this could be fixed in firmware, and I haven't kept up with the updates since v1.75. You do wonder about a product that's initial release was v1.73, though.
