Sadly, no. > If not, what could be used? There are a few suppliers of SDTV systems that shoot at about three times the normal frame rate (i.e., 90fps) and record to modified tape decks or to hard disk, for slo-mo playback. There are also high-speed digital systems (http://www.visiblesolutions.com/ phantomv5.html) that typically record to computer memory, but not in a broadcast-type format -- these record proscanned images for action analysis and machine-vision types of applications. Film cameras are still used, like the Actionmaster lineup from Photosonics (http://www.photosonics.com/Rental/Actionmaster.html) that go up to 500fps. Be warned that they have a prodigous appetite for film: a 400 foot load that lasts 11 minutes at 24fps is gone in 32 seconds at 500fps! The 4C (http://www.photosonics.com/Rental/4C.html) will run 35mm at up to 2500fps -- at which speed a 1000 foot load lasts 6.4 seconds! The Photec IV (http://www.visiblesolutions.com/pac.html) burns 16mm at up to 10000 fps -- or 40000 fps using quarter-frame images. At those rates it' s cheaper to own and fly a personal jet.

I think you'll find that the 11 uses a peak-end limiter instead of an ACG -- it clamps, but doesn't pump. If you feed it a unity-gain signal at nominal -10dB levels you'll get clean, undistorted recordings preserving the dynamic range of the signal. But if you start to get a bit hot on input, it will most likely limit the excursions to avoid clipping. I say "most likely" because I haven't tried recording analog on it. I can test it next week if anyone's interested; I have a couple sitting around at Omneon.

I don't think so. You can always see the FX by parking on the frame. As Gary mentions, on a fast machine (no pun intended) many FX render faster than real time anyway. And you NEVER have to hit Option+R to render ANYTHING -- heeding Crayne's Law ("All computers wait at the same speed") the FAST folk (like the iMovie mob) made their computers WORK for a living by using spare CPU cycles to do automatically what needs to be done sooner or later anyway. That is progress. Gary adds: > Down the road it will be ported to Pinnacle's real-time hardware as well. This is (I think) the key point behind Pinnacle acquisition of the FASTstudio product line. Pinnacle's hardware is capable of much more than Premiere's architecture allows for exploiting. Studio -- now Edition (and what happened to Liquid?) -- has 5+ years of development behind it as a driving platform for all manner of hardware-accelerated operations. Pinnacle now has an in-house NLE that they can use to leverage their hardware optimally. It'll be interesting to see how this new twist in the road develops. > I think it'll find a place in the market.

Another key point -- Pinnacle has priced it sensibly and competitively for the US market, something that FAST was never able to come to grips with (in fairness, FAST was used to selling at much higher prices in northern Europe, where FASTStudio is very successful -- and FAST's business model and cost structure may not have allowed aggressive price cutting). Pinnacle also understands marketing whereas the FASTStudio line was almost entirely unheard of in the states when FAST was in charge. purple, blue, and silver (and whatever crawls from the dank cellars where mad Pinnacle scientists are engineering the fusion between Studio SW and Pinnacle HW) may finally get the exposure -- and respect -- they deserve. This all bodes ill for Premiere, of course. But recall that back when Premiere 6.0 was introduced, and I was discussing it with an Adobe product manager, he said, "yeah, 6 is OK. But 7 will be where the real action is." Don't count Adobe out just yet... Cheers, AJW [Any bizarre line breaks courtesy of OS X's Mail.app. Think Different!] Has DVRaptor RT an analog input and output? - Jon Burkhart The question also asked about input to the DVRaptor RT. Input is ONLY firewire, no analog. The DVStorm has both firewire and analog input as well as output.

As I mentioned, the DVStorm does take analog input as well as firewire. Also, it is not necessary to have your camera hooked up to the system when editing with the DVStorm. Of course the DVStorm costs much more money, but it's well worth it, in my opinion. Aloha, Jon Burkhart Giorgio wrote: > > Therefore is it impossible to use an analog videcamera to make editing? > Or are there some expedients? > thanks > Has DVRaptor RT an analog input and output? - Jon Burkhart With the cost of the DVRaptor RT plus the cost of the Canopus converter, then you're near to the cost of a DVStorm which is a better choice, in my opinion. Aloha, Jon Burkhart Steve Slocomb wrote: > > > Just on output-get a Canopus convertor for the input. > Ref AVIs - Jon Burkhart Mike, if you will reference page 3-17 of the User's Manual (sorry, I couldn't resist) you'll see the reference files are just pointers to the REAL avi files that were captured. Your procedure of making another reference to other reference files should have no effect on the quality of the video. They are just pointers pointing at other pointers. The only degradation would be where you altered the video in any way and that would be minuscule. Rather than make a reference of the "final" edit I would make my MPEG2 Elementary Stream directly in Storm Edit.

I am using a DVStorm. > Ref AVIs - Jon Burkhart Mike, you're right about the manual; it's not the best. But, it's a vast improvement over earlier ones, believe me! As for Authoring, I use ReelDVD. I bought it just as Sonic bought the rights to it. They don't promote it very much, but it does all I need for the foreseeable future. Does great conversion from WAV to AC-3 stereo audio (not 5 channels, just two, but that's enough for me) and they allow motion menus as well. I enjoy using it very much.
