Vegas 4 power users - quick question re: stills

[housepig]

I hope someone can help me out, before I set out on the wrong path...

I'm working on a project and it's going to be narration over a Ken Burns-style montage of stills.

I've made low-resolution copies of my stills so I can play around with the arrangement without eating up a ton of system overhead (300K images instead of 20-25Mb images).

what I want to know - is there a way that I can select an image, once I have it motion-tracked, zoomed, etc., and replace that image with another file (the high resolution one) once I'm ready to do the final render? Or am I going to have to substitute them out by hand?

If anyone can help, please do - I'm going offline for about an hour to work on the audio portion, and then I'll come back on and see if anyone has responded. I just want to make sure I don't end up making a bunch of needless work for this project - I have to show someone a rough draft of it tomorrow at lunch (15 hours from now).

any advice appreciated.

sounds a little too simple but why dont you try renaming the high res files the names of the placeholders and switching their location

something i might try...

hello,

how about if you add the high-res pic as a 'take'?
it'll have all the motion, fx, etc.
to add as 'take' just right-click on the high-res image in explorer and drop at the event and then select the - add as take
