strange Event Pan/Crop blur
I’m in final stretch of a basic slideshow image project (pictures with a bit of motion and music), and I’ve taken the same steps I’ve always used for this sort of thing – namely the Event Pan/Crop tool.
This time, however, I’m noticing something very strange with the images. Specifically when I zoom in or out of an image, there is a certain point where the image suddenly blurs. It’s not that much really, but it is a very noticeable jump from one frame to the next. It’s as if I had set it myself to blur at a set distance (though to my knowledge I haven’t done anything like that).
This is a standard def widescreen project, and I’m using Vegas Pro 10. I’m hoping the fix is something easy I’ve overlooked. Any thoughts Vegas gurus?

Are you seeing this blurring on the preview or in the rendered output?
If it’s only on the preview, then try setting the preview quality a bit higher and see if that makes a difference. The “draft” and “preview” quality levels make a lot of compromises in the preview image quality to speed up the preview.

First off, thanks for the quick reply.
Unfortunately, this is occurring in the final render. I’ve been messing around with some zooming in and out of these images from projects with different settings and what I’m universally noticing is:
SD – the blur appears fairly consistently in previews and renders
HD – the blur does occur at auto preview quality, but does NOT at best quality preview, nor in renders.
I’m still fairly stumped to be honest.
For the time being, my plan is to redo (ugh) the project at HD settings, and later re-render it in SD (hoping the corrected HD image will downres without the odd effect).

How big are your images? Vegas is not a photo editing program so if you are asking it to resize huge 14MP images to less that 1MP (which is what SD is) things might get a little burry. Try rendering at BEST settings and Vegas will use a better resize algorithm. Otherwise try reducing the size of the images in a photo editing program (like Photoshop) to about 2x your output resolution and see if they hold up better.

Though I’ve already redone the project in HD and re-rendered the finished file to SD (which did work), I decided to try out the lowering resolution idea which does seem to fix things:
While I was rendering out at the “best” settings already, most of these images were in the 8-12MP range. After drastically reducing the resolution (to about 2.5x SD) that strange, suddenly appearing blur went away.
So in the end, problem fixed (and thank you). However, it almost makes me even more curious: why, if this is the case, does the image not consistently lose focus or become blurry? Is there a reason it happens suddenly at a certain crop size?

You are taking 12MP images down to 0.3MP. That’s asking a lot. The more you resize, the more things get distorted/blurry. So resizing less maintains more clarity.
