Yes, the thread seems a bit abandoned.
Don’t be sad and upset, it isn’t worth it 🙂
I think your cpu isn’t strong enough to work with raw hdv, it is similar to my previous system, and I got the same low framerates then. You should try the preview-auto setting with a 1/4 size screen, that’s probably the best preview of raw hdv you’ll get.
If it’s unworkable, you should use proxys (just render the clips to DV, and exchange them with the HDV content when the edit is ready), of render the material to the cineform intermediate format (never gave me full rate playback either).
Updating to a modern quad system will give you full framerate at half size. There are people that claim to have full quality /full size preview on such systems, but it’s a mystery how they get it, since they don’t answer when I ask them. In some recent postings on the sony forum (about the preview performance of V8) confirmed for me that many people don’t have full quality preview of hdv, even with a quad Q6700 processor.

Hope someone still notices this thread:
I’ve done quite a lot of experimenting for HDV playback on Vegas7 and the new quad system, with the following results:

– I CAN get full framerate of m2t playback at Preview Full quality, however, ONLY on a seperate preview window (and not the ‘secondary display’ setting). And tt works only if Dynamic RAM is set to 0, and ‘Simulate Device Aspect Ration is turned off.
When I give Vegas some dynamic RAM, the framerate gradually goes down and comes to a halt.
When I put Simulate Device Aspect Ratio to on, the framerate drops consistently to around 18 fps.
So the full framerate is good news for me, however by switching “Simulate… etc” off, the image is always distorted (characters are too tall). So my question to Spot: are these settings what you meant when you said the preview window should be correctly sized to avoid scaling? Do your workstations also have a distorted (stretched) preview then?

I installed the latest nvidia driver.
On my new computer I can play a hd mpeg2 file in Windows mediaplayer fluently, (without purevideo installed), so the card and driver can keep up with the amount of pixels.

Thanks for replying Spot. It’s a relief to hear that at least it IS possible to have full framrate/full resolution HDV playback from the timeline.
Still, I don’t see why I don’t have it. This is an absolutely virgin system with very fast specifications, nothing on it but Vista64, Vegas 7, and some m2t files. Not even an internet connection. So why should I experience problems already?

I assume that with “preview window correctly sized” you mean: preview on secondary monitor, with the options “scale output to fit display” and “display frames in video preview window…” turned off?
Or do you mean I should preview in a preview-window that I drag to the second monitor, and that is given the right size by double clicking the top bar (but that gives me even worse results)?

Also checked if it could be the m2t media. In Vegas Explorer the “Name” is listed as “m2tsplug.dll” and the “Format” is listed as “Sony M2TS,” so according to John Meyer at the Sony forum, it should be captured correctly.
Also it says there about the media: 25fps/interlaced, 1440x1080x32, So I use project settings 1440*1080, 50i.
Empty project, just try to play the one file from the timeline.
Have I been missing something still?

So you get full preview after looping once. But I just want to play a clip from the timeline and see it as it was meant to be on a big monitor.
You say you have a quad as well, what framerates do you get then, when you just play m2t from the timeline at preview-full quality (whithout looping to store in RAM)?

[Arthur Bueno]

could you define ‘quite happily? Is that full size on a large monitor, at at least preview full setting? Are you looking at a fluent, truely 1920×1080 image?

[Arthur Bueno]

I have 4 internal drives, but not on raid. But drive throughput can’t be the issue, it’s small for hdv(same as for dv). I gathered the bottleneck is cpu power, but apparently not. Might it be the videocard? Which one are you using? Could you give me some specs on your system?

Mine: Intel Q6600, Gigbyte P35-DS3P, Samsung 7200rpm 500gb SATA drive (and some other 7200 IDE and SATA drives), Asus 8500GT silent. Vista 64 Home premium. Just put it all together, install Vista and Vegas, play a m2t clip from the timeline to secondary 1920×1200 Dell monitor,and voila: 13 fps (I exagerated a bit in the last post)..

About project settings: it’s PAL HDV, and settings I use are 1440 x 1080, 50i, upper first. Should be ok, or am I making a mistake?

That forum has more than 220 posts on Vegas 8 now.
It makes you wonder what kind of community we have here: dead silence…

Hey! Titler! 10 bit! Multicam! Better previewing! More scriptable! Read all about it.

i just installed V7 on fresh Vista 64 installation. There was a problem with the mediamanager, needed some file for that. but the rest did install well. The mediamanager I can do without, so no further problems.

If your footage is dv, you should easily have a realtime preview. We had that already in Vegas 3 on 5 mhz machines. Most likely you’ve set your project settings wrong. Go for the NTSC or PAL (dependent on what sect you’re in) presets in the project settings, connect the camera to the firewire port, and the monitor to the camera, and you should be ready.
