Better motion blur

Hi. I'm looking for better than built-in motion blur (Vegas 8/9 Pro). Something like ReelSmart Motion Blur (http://www.revisionfx.com/products/rsmb/). Of course I can buy BorisRed and next ReelSmart, but I'm looking for a little cheaper way.
Maybe any stand-alone software, not expensive software? I trayed VirtualDub and its MB filter, but result is similar to Vegas MB - I'm lookin for motion blur with motion analyze, depends from motion's directions.

You can buy the plugin from Toolfarm for $142.
In general anything to do with motion analysis does not work terribly well with Vegas. It might be time to consider investing in After Effects.

You can simulate motion blur using Gaussian Blur in Vegas. Depending on how accurate you want the outcome though it could involve a mind numbing amount of manual work with keframing and masking.

I want to blur motion in stop-motion and similar movies. Maybe if not pluging, any tip or trick, how makes it more natural?

If that's what you need, RSMB is the least expensive tool.

There are several others, but they cost more money.

That's a difficult one and motion blur is one of my obsessions.
If you're animating an object in Vegas or After Effects then both can create tweened frame and use them to simulate real motion blur. Vegas calls this Supersampling.
In your case this is of zero use as your not doing the animation in either Vegas or AE so neither know anything about the motion of the objects. The other issue with this is the technique is not quite as good to the eye as real MB, you can oftenly see the MB as ghost like trailing images with no blur.
You could emulate that technique in stop-motion by say shooting at 4 times the target frame rate. Say you want to endup with 25fps then you need to do 4 time the work. But you set your Vegas T/L to 100fps, apply the MB envelope at 2 or 3 frames to give you a 180 or 270deg shutter, render that out or nest it and then slow it back down to 25fps and you'll get a MB of sorts. Friggin lot of tedious work, again.

That's all I can think of short of sucking it in and buying the right tool. On the upside as you're shooting stop-motion you should have very clean images with no noise which should mean the motion vector software will work very well.

If you try to do it with super-sampling in Vegas be aware of two things:

1/ Super-sampling only has an effect on animation movement that Vegas generates itself. It won't have any effect on an imported animation for instance. It will have an effect on titles where the movement is generated in Vegas.

2/ Super-sampling increases your render time orders of magnitude. You probably want to prerender any supersampling sections so as not to slow down your whole render. If you are doing more than small sections, you probably want some other tool.

Malew, I do not know if you can accomplish what you want with one of these plug-ins, but maybe you should take a look at CreativEase from Pixelan:

Watch the videos with examples from the Time Effects Packs (StepMotion 2 and StepTime 2):

You can download a free demo.

Looks nice, I have to try it. What I want to do? Imagine big color stain - f.e. any logo, circle, rectangle. I want to move it across the screen from left to rigt (or right to left). And if I have 100 frames (stills) and I render it to the movie - it is not smoothly, Annoying and jerky.

At low frame rates motion blur is one of the vital things that stops judder.
At 24fps anything less than a 180deg shutter angle and things get jerky. This is sometimes done deliberately e.g. Saving Private Ryan. Even with a 180deg shutter at 24fps you still need to watchout for many other issues.
Stop motion gives you an effective shutter angle of 0 deg because the subject / object is not moving while the shutter is open.
There's another potential problem too. Because stop motion is generally shot with digital still cameras you can get very high resolution images with sharp edges. These can further add to the judder problem as well as cause issues with aliasing and line twitter in interlaced video. Then to cap it all off all the sharp motion can make for problems with any codec using temporal compression.
