DVCAM vs miniDV - (2) FireWire switching solutions Utility of Hardware WF Monitor with DV/Firewire Vx 1000/9k discussion group Dsr 11 or DSR 20? - Adam Wilt Does anyone on the list have any experience with the DSR-11? Yes; been working with two of them since January. > Is it a good deck to use with FCP? Yes, it works very well with FCP. > Is it sturdy and reliable? So far the answer is yes. > Would the DSR-11s sold in Europe be the same as those sold in the USA? Yes. The power supply is multivoltage; you'll only need the line cord changed for the different AC plug. I've run the decks in both NTSC and PAL and there is no compromise in one standard to favor the other. Note that unlike multistandard VHS machines the DSR-11 does NOT transcode PAL to NTSC or vice versa. It simply plays or records in the standard you tell it to. See review at http://www.dv.com/magazine/2001/0401/wilt_rev_0401.html. Cheers, Adam Wilt DVCAM vs miniDV - "Perry" Hi Don: It's probably me that has created the doubt! The point is that using DV decks/cameras to play DVCAM is no problem because you have a narrower head playing a wider track (you'll theoretically suffer a little worse drop out). Using a wider DVCAM head to record DV causes some overlap of track recordings, and without getting into all the numbers, it sort of uses up some of the built-in tolerances for machine interface. Exactly the same thing happens with LP/SP recording on DV cameras. The bottom line is that Sony only recommend that you use it for short term purposes and when the same camera will play back the recordings. In this case I would suggest you ask your son to check whether the DV equipment available in his lab is Sony and can therefore play back DVCAM. If it is; then it is best to record DVCAM format on MiniDV cassettes. If he has non DVCAM compatible kit; then he will need to record DV and you may need to be prepared to loan the PD-150 for replay purposes! In my experience the chances are it'll work anyway and Sony are just being cautious.

The wider track is only produced because of higher tape speed. Remember the recording is done on a helical track, that is what is confusing people.< I'm guessing you meant to say DVCAM and DV (miniDV is a tape cassette). The heads ARE different widths, I've even got a micrograph somewhere to prove it! >The fact that a DV CAM machine can read a DV tape is proof of this, because if the DV CAM head was wider it would be reading one and a half track and that would result in garbled data.< The two heads on the drum are angled slightly to the track (it's called azimuth) so that each head will not play high frequencies recorded by the other. Digital data is mostly high frequencies, so this is why the DVCAM can play DV with a wider head. It is also why both formats can work with no guardband or gap between tracks.

Both passive switchboxes and patch panels are now available: go to http://www.markertek.com/MTStore/Store.cfm?Search=1394 and look down the left-hand column for the patch bay and 6x1 FireWire switcher. > What we need is something that can act like a virtual patchbay - or > physical for that matter.

At Omneon we've added functionality to our switch to act as a bridge or router, if you will; individual NLEs or VTRs can be hooked up fat dumb and happy to a 1394 bus on the switch and speak S100 on channel 63; the switch transcodes it to S400 on whatever channel we assign, so that multiple NLEs or VTRs can be agglomerated on a single bus talking to our storage controller, while each one still thinks it's the only one out there. Unfortunately our switch is an integrated component of our 1394 routing fabric at this time, but resources and market allowing we may yet build one to serve as a standalone device. Don't hold your breath though; for the near term we have all the "opportunities" we can handle just meeting the needs of broadcast customers for storage systems! Cheers, Adam Wilt Utility of Hardware WF Monitor with DV/Firewire - Adam Wilt Seems the waveform monitor would be useful if you're working in analog. It's still useful in DV to see *exactly* what you've got -- and when editing, to ensure you aren't adding filters, effects, or synthetic images that violate the strictures of NTSC or PAL encoding -- illegal colors, too-hot levels, and the like. On the set or in the studio, a WFM is like an analog gauge on the car's dashboard (you see what the engine is doing) compared to the "idiot light" of a zebra setting (which only tells you when things have gone wrong).
