WYSIWYG via SDI?

I really like the Vegas way of editing video, I also like that the fact the the audio portion is so powerfull, I would even arguefor for sound for picture it is THE most efficient and powerful editor. I can do in minutes in Vegas what would normally take hours on Nuendo or PT.

But for professional video editing I think it is VERY important to see what you picture looks like. I am using an uncomprerssed QT SD file and the frame rate is low and the picture is bad.

FCP, Avid, , Edius, and Premier all are able to show the final quality while you edit.

Vegas would revolutionize the way we work, but I can't edit on a system where I can't see 30 fps on a real CRT monitor.

If I add a Decklink card will I get the full quality in the monitor, or will it be a dummed down image?

FYI- our current workflow, is mix 5.1 and stereo innitially in vegas, then edit video in FCP.

Vegas can send vision out SDI via BMD or AJA SDI cards at full quality. Getting 30fps depends at final render quality is dependant on many factors. The biggest problem is that Vegas will not use any form of hardware acceleration apart from the CPU. Depending on what and how you're editing this may or may not be significant.
The biggest advantage though to Vegas is you never have to wait for anything to render before you get to see 'something'.

Also, you realize that a ppro system does have to render when it thinks it can't play the media in realtime. That's what the red bar at the top of their timeline is all about.

You could also prerender in Vegas but Vegas doesn't insist. And the prerenders are very persistant anyway.

The preview windows in those programs tend to be inaccurate. And they aren't good at showing things like reversed field order, interlace flicker, overscan/cropping (unless you have safe area markers on).

If you're using DV you can preview the stuff via firewire out.

Yes / you can adjust preview quality.

thanks for the replies,

Maybe my system is just bad for Video editing, it is a 2 year old dual Opteron with a Matrox video card. I cant even play DV in real time. The preview window looks nothing like real video, Whereas the other applications I mentioned seem to be fine.

In Vegas when I play an uncompressed SD file it uses about 40% of the CPU which equals maybe 70% of one CPU to play, and the quality in the preview looks pretty bad.

I will try those other applications on my system to see how they play. I will also hook up my Canopus AVDC to see if vegas can play out at true NTSC quality.

thanks,

A Celeron 700mhz will play back a stream of DV so your dual Opteron should have no problem with it.

Something is likely not setup right.

Perhaps the clue that you're missing here is the Preview size and quality setting. Look at the Preview Pane in Vegas, on the top of the pane there a drop down that lets you control preview size and quality.
At the bottom is a couple of indicators that give you a clue as to how much of the frame and how many of the frames you are seeing.
And when you say "doesn't look like", can you be more specific, what is missing, are you getting jerky motion, i.e. dropping frames, is the rsolution not good or are the colors off?
