If you're talking about the working video it would make the most sense to stick as closely as possible to the source, preferably without compression. But HD resolutions make that impractical. I don't see why you'd want the working video to be something as bizarre as 3000x500@10fps if your source is 1920x1080@25fps. Display it any size you want, but with motion jpeg as a source, you'll lose quality resizing it, then you'll lose quality again rendering it.
Quote: Another ridiculous constraint is that still images in a video project (Adobe Premiere Elements) must not be larger than 4096 pixels on the long edge. If they are, they are silently resized to project resolution and look awful in any zooming effect. I must have damaged the wall with my head when I eventually found that one out...
Since the proportions of Pentax DSLR still aren't 16x9 or 4x3 you'd be better off resizing the stills in a program for editing still images then importing the edited versions. The maximum resolution on the K5 is roughly 5x3 so for full frame at 16x9 you'll need to crop. (edit) I see now that you want to use zoom effects, so I understand why you want to use as high a resolution as possible. It may be that Adobe are forcing you to buy Adobe Premier to get the full resolution.
I've been using Vegas Movie Studio for video editing but I'd be interested to hear about the quality of results from different programs in terms of their rendering abilty. The rendering from Movie Studio doesn't seem to be as good as the results I've seen from other software - even linux freeware. It's not bad, but it doesn't seem to be anywhere near the best either.
