Vegas automatically scales anything you drop on the timeline up or down to your project properties setting.
For example, if you're set to NTSC DV (720 x 480), an HDV file is down converted to this size and a 100 x 100 gif image is up converted to this same size.

In PS Save entire image or selected object might be your problem

When you work in PShop to your SVegas project size save entire image

xfx: I think you're talking about PNG files?

What are the dimensions of the Photoshop file, in dpi (pixels per inch) and pixels? Also, is it a .psd file?
edit: Also, can you set it to the size you need with pan/crop or track motion?
edit2: oops, just read your initial post, you do use track motion. sorry.

dpi doesn't matter in the slightest and is of absolutely no concern in any way whatsoever. The dimensions of the image in pixels are what is important.

The "dpi" setting is just a note to the printer, so they know what resolution to print at (really the size to print, as the number of pixels divided by the dpi = size in inches).

In current versions of Windows and OS X, there is no concept of specifying a size on the screen.

That will come soon however, although from a standpoint of resolution independence.

thanks Mike, that makes perfect sense. I was just wondering if I was missing something in PS.

Dave, if you want it to appear at it's original size in Vegas, drop it on the timeline, go into Pan/Crop, right-click and select Match Output Aspect and then enter your project value into either the Width or Height boxes (top left of the Pan/Crop settings menu).
This is a PITA workaround but, short of putting the image over a full-size a transparent background in Photoshop, it's the only way I know of.

DPI is also useful with scanners.

DPI for screens is just a weird idea. How many DPI is a 1920x1080 image on a 24" screen? How about in a 24' projection?

"dpi doesn't matter in the slightest and is of absolutely no concern in any way whatsoever. The dimensions of the image in pixels are what is important."

That is essentially true, BUT, I was trying to figure out just what was being done. If you change dpi without checking "do not resample", the pixel dimensions change.

True. I'd forgotten that because I never touch DPI settings (since DPI is irrelevant), but if you're thinking in terms of DPI then you're much more likely to make the mistake of adjusting it.

DPI is an issue for print and this is why, at least in photoshop, the setting is ganged with settings for an image's dimensions in inches or mm.

The reason Vegas always resizes images to fit the frame is that Vegas *Always* resamples everything to make it fit into the project. This makes lots of sense for time resampling, like making 15 FPS media run in a 30 FPS project, or making 41k audio run properly in a 48k project. It gets confusing, though, if the size of an image is being changed to fit the frame.

It gets especially confusing when your images are "almost" the same size as your project because you may not immediately understand what's going wrong.
