Hi... sorry the delay in responding. I also have to run off to a meeting, but here are my quick replies:
are PSD files just as lossless as TIFF and PNG? AFAIK, yes.
if not, couldn't Photoshop open up TIFF or PNG files for batch processing? I definitely want my folder of raw images to be in the most universal format with the highest possible amount of detail. Photoshop can import TIFF and PNG files too, so I would think any of these formats would do fine.
after batch processing my raw through Photoshop...am I still at very highest resolution and detail, or have I now applied (along with whatever cropping or filtering or effects I wanted PS to do) compression or lossy of some sort? As long as you save back to a lossless format you shouldn't lose anything.
that frame size of 640x480...it won't take me to 16:9 aspect ratio, right? I need to shoot this movie in wide format. Not an expert here, but if you're going to DVD, you have to wind up somehow in a 720x480 DVD-compliant format, whether you do the conversion or your DVD authoring program does it. Whether or not the clip, once converted, displays correctly on a 4:3 or 16:9 display is determined by the original render dimensions (i.e., whether the images were rendered in a 4:3 format like 640x480 or a 16:9 format like 852x480 prior to being converted to the DVD-compatible format). NOTE: For much more detailed and nuanced info on the various video formats, see http://wiki.helpware.net/index.php?page=Video
making a .MOV before going into the DVD authoring software...isn't there a compression invoived there? Can't Ulead work with a folder of imdividual images? I don't believe Ulead can import individual images (at least I haven't found such a routine) though there are programs which can (such as, I believe, Adobe Premiere... which I don't have). AFAIK, QTPro does not impose any compression when you load a lossless image sequence then save it as a MOV. When imported to Ulead, though, Ulead adds compression. It's not perfect either, since I can see some jagginess on diagonal, high-contrast lines; but it's better than anything else I've found.
If you find a better way, let us know! Or perhaps one of the more knowledgable folks here will chime in.
Cheers...
