Dont want the blur, or supersampling. How?

I really like Vegas video editor in comparison with other software available, but I have one major issue with it that prevent me from using it in a meaningful way.

All video that I produce with it are blured, and i cant seem to find a way to get rid of it. I use default settings and I still get the same effect.

Let me explain: I insert my DV video into Vegas (I use version 6.0, build 210). I then select the whole thing and render. The result has blur. I.e frames are averaged and the video quality is no longer sharp I see shadows of people everytime the camera moves. Naturally I dont want this. I looked this up, and it seems to do with blur or supersampling. But I am not adding any blur envelop and I dont know where supersampling option is controlled. The only thing I have seen is that when I go the properties of the video that is inserted, there is an option thats says: Smart resample. That is checked by default. Changing it had no effect anyway.

Could you please tell me how can I get the same original quality (without shadows and blur) out of vegas and just use it to convert a DV to WMV or whatever else i want to compress it to.

Many Thanks

Can you confirm that you are seeing this prior to render too? You haven't actually stated this? What Previewing frame rate are you obtaining? Are you at full frame rate when you Preview? Are you previewing at BEST and getting low frame rate? Or, are you Previewing at something lower, thence you would NOT be seeing the effect you speak of? I'm asking this because if I noticed an effect I didn't want, I surely wouldn't proceed to Render without removing it. However, and maybe it is in the way you have framed your question, I'm understanding that you could be implying that it is solely the Render that is giving you this supersampling? Yes?

I must say, it does smack of a Video Bus Track being employed over the WHOLE project. But please get back and tell us if you ARE seeing this prior to Render.

I suspect you're output frame rate is not the same as your source. This will cause Vegas to resample which will create 'tween' frames.

That's a real shot in the dark guess though.

It'd really help if we had some specific details, like is the PAL or NTSC footage?

It's also very likely that the defaults are wrong, especially for rendering to WMV but even the project defaults might be wrong for your footage.

Or as I think Grazie is hinting at, you've added a motion blur envelop.

Even editing with Quantize To Frames Off can cause some wierd results from memory.

Right-mouse-button clicking on the source clip on the timeline and choosing Switches / Disable Resample will probably help a lot.

I think Bob (farss) nailed it: I'll bet you are using an NTSC template when your source is actually PAL (or vice versa).

Right click on any video event on the timeline and then choose "Properties." Note both the fps and the field order.

Then, find the project properties icon in the upper left corner directly above the preview window and click on that. What is the frame rate and what is the field order? They should match what you recorded above.

Thanks for all your replies. They were very helpful. I had a look around especially on video properties and the project properties.

The problem seems to have been solved now. You are right . It seems that these settings should match each other and are not picked up automatically based on the video source's parameters.

For the record I have a PAL video sources, project settings are:
720*576
Field order: none progressive
aspect 1.0926 PAL DV
Full Res: Best
Motion Blur: Gaussian
Deinterlace: Interpolate fields

The video file properties are:
field order: lower field first
aspect: 1.09 pal dv
alpha: none

Smart resample is true.
reduce interface flicker is cleared

These settings work and the shadow effect is gone.

Thanks for your help
