Ok this might sound like a very stupid question. But i need to get my doubt cleared. I'm looking to go into HDV editing and just wondering if i edit my clips in HDV can it be displayed on a SD monitor that i have? Any advice? Thanks

In addition to an LCD monitor that supports the 720x1280 HDV resolution I need, I am planning on using my (supposed) 850 line 19 inch "broadcast" monitor with SMPTE C phosphors and "blue only" so I can calibrate to bars. I think this will be very useful to help me get a clearer idea of where my color and brightness are (along with my scopes of course).
Do you absolutely need the full resolution in your studio at all? Aesthetically, it certainly is great to see the full beauty and clarity of your work. And for clients, this ultra-sharp image is what HD and HDV are all about.
But functionally, one might argue that by the time you're in the studio, all that sharpness doesn't really help you cut, and by then it's a little late to get the focus right!

...but it's not too late to choose shots based on whether or not they ARE in focus.
This is the area that will bite you. An SD monitor will do everything but show you focus.

Remember, to output HDV from the time line you will need a dedicated capture or special video card. HDV will not go up the firewire in its AVI form. At the moment it is difficult to monitor HDV whilst editing.

Great point, Tim.
But who amongst us would shoot out of focus? Moi? Well, okay, once in a while.
Anyway, I'm certainly going to use a hi-def monitor myself as noted in my post. What I'm using for HD display is a Samsung LN-R238W LCD-TV and this thing is so crisp and clear it blows even a Sharp Aquos way, way away. What else besides LN-R series Samsungs have contrast ratios fo 3000:1? Mine's the 23" but they also sell 26", 32" and I think 40." Resolution is in the basic area of native 720x1280, I think 756x13something. Anyway, check the C-NET customer reviews, one guy says "This is the best TV ever made!"
I have some concerns that this thing's picture is so enhanced that it will lull me into complacency by masking problems though. Hence, always good to have that good old broadcast CRT sitting next to it, SD as it may be.
And Redgum, since I'm using Aspect HD and a Parhelia graphics card, the system should display the Aspect HD intermediate codec in real time over the component outs (supposedly at least four layers plus effects, etc.), as far as I know -- haven't set my system up yet as I'm waiting for completion of my new studio (detached from my house) -- so I can't say from experience. There is rendering for print-to-tape of native HDV over firewire, although hopefully very brief.
I got a pretty good box to help drive the real-time features of Aspect HD and speed those renders: twin Opteron 275 dual cores (Aspect can use all "four chips" for most of what it does), 4 GB dual channel RAM, and an array of four Hitachi 500 Gig drives which formats out to just a bit less than 2T. Also a 10,000 rpm SCSI system drive.
I can't wait until my studio's finished and my system is up. My wife can't wait until my studio's ready and she gets my old office/den for her home-schooling classroom.
