Caveate here though.

If your project is NTSC 29.97 then a 5 second duration will make your stills last for 149.85 frames. You want it to add up to whole frames so set the duration to 5.005 seconds.

Never thought about that. Is this just a techincal issue or does it really make an impact in the final product? Must say I've made alot of slide shows but never notice this.

What appears to happen is that Vegas will round to the nearest frame boundry at the 5 second point. It seems to be pretty good at keeping this up over the long haul so that some of the images will be 149 frames long and most 150 frames, with the average time still 5 seconds. I did one collection of 660 images at 1 second long each and the total time hit 11 minutes right on the closest frame mark. 20 of the images must have ended up as 29 frames long, the rest at 30. As far as which were only 29 frames long, i haven't a clue. I'm not gonna go trolling through the timeline frame by frame to find out either. No one ever noticed while watching it, so i don't really care.

It's pretty easy to see where it happens. Just crtl+alt+arrow through the timeline. You can do it with maximum magnification and you'll see where the clips are abutting mid-frame, overlapping by part of a frame, or creating a partial gap. When events are snapping to each other's boundaries then they just end up starting off the frame mark.

Of course this often happens when the audio stream is a little differnt than the video stream of an event.

It seems like a worthwhile precaution just to avoid this. If you're working in NTSC then go set the still frame pref to a round number of frames. Just remember to change it again for other project templates like PAL or multimedia.

Of course this also happens when the audio stream is a little different than the video stream of an event. However, this is less likely to be a problem because you'd usually trim the event up a bit-forcing it to be an even number of frames long. The bigger problem is pics and generated media that are left untouched as they could all end up to be an odd length.
