Thankfully the organization is already using scan converters and capture devices for screens that have either near-broadcast rates or native video generation. My question was to help address the devices that have no “video out”, such as handheld gaming devices. (I know that some handheld devices have video out and/or development kits with that capability, but the items in question do not.)
Good point about the different terms for this feature; I found the following:
- Clear Scan (Sony)
- Synchro Scan (Panasonic)
- Variable Scan (JVC)
However, the tech specs of most of these state that the feature starts at 60Hz and goes upward, which won’t help me with anything lower, but this can probably be addressed by using an even multiple of the native rate and playing with ISO settings (ie. if native rate is 55Hz then try shooting clearscan at 110Hz, etc.)

Thanks again, “clearscan” is likely the term I’d been missing. Very much appreciated!

[Rick Wise] “Will you be shooting more than one device in the frame during each shot?”
Thankfully, no. Only one device will be present in each shot.
“You can also look up the specs of any cameras you are considering.”
Hopefully, but they have specs such as (quoting from the Sony NEXFS700UK page) “Manual:60i/30p/60p: 1/3 – 1/10000”. This isn’t specific enough; I can’t tell if this is a range of included shutter speeds, or if they are implying that ANY shutter speed in that range can be selected.

“The rolling shutter wouldn’t be a s big of a problem in what you are doing unless the motion on the screen had a lot of vertical lines moving very quickly across the screen.” Unfortunately, there will be a lot of exactly that.
Thanks for the vote for a professional cam.

Wait, I just saw your original post. So you’re having stuttering in Windows 7? My son’s computer does too, even doing easy stuff like playing a regular DVD. Windows 7 is a release candidate, not a fully-released product, and it has some problems with video playback. Do not run Windows 7 for video editing.
If you remove Windows 7 and instead put in Vista x64 you will easily be able to edit HD in realtime. I have a system similar to yours and run Vista x64 (64-bit) and can quite easily edit 24p and 30p sources. (60p works too, but drops down to a lower framerate while playing off the timeine if I apply effects and don’t render.)
-
You shouldn’t have to upgrade anything; your system is already powerful enough to edit HD realtime, no matter what operating system you choose.
Are you trying to do so, but encountering problems? Or was this just a question?

“it had at least 7 dynamic links AND one of the links had some major 3d going on… with tons of layers, levels, plugins and the whole sha bang… “
Yes, that is the problem. Any incredibly complex sequence probably should be rendered so that you’re not re-rendering it all the time. Dynamic Link is good for sequences that your computer can handle — it is not meant to be used for everything.

I started seeing these in CS3 about a month ago when I updated my nvidia video card drivers. I need the drivers for other applications, so I just ignore the lines. They’re irritating but they don’t affect the output.

If you’re having trouble exporting directly to MPEG-2, try exporting to Movie first (ie. render out your timeline to one large clip), then double-click the clip, THEN try your media encode to MPEG-2. I remember having this problem with 1.5 and that’s how I got around it.

That isn’t what I read at all. I read that it is truly a 64-bit application; when you run it in 64-bit Vista, every component that runs gets access to it’s own 4Gig of RAM (assuming you have more than 4G).
It is true that it is only 32-bit for Mac (for now).
