No need to convert to tga. Psd is just fine.
Output will still be 720x480 on dvd.
If you are planning on doing some panning and zooming you need to make then twice as big.
I completely agree with Ann. If you have re-sized in PS, no need to go beyond that, unless you are doing something special, that you have not yet shared with us.
You have made mention of the Alpha Channel. Will you be using this to "knockout" the background, or something?
Do the resizing in PS.
(1) Bring the image into photoshop
(2) set the pixel aspect ratio (IMAGE dropdown menu) to the appropriate value--0.9 for DV NTSC, etc
(3) Set the color gamute (EDIT menu dropdown???color preferences) to NTSC1953 or H264--whatever is appropriate
(4) Using the crop tool, set the dimensions to 720 x 480 pixels and crop the desired image. For highest quality the crop window should encompass more than 720 x 480 pixels to avoid scaling up the image) There is no need to set the resolution--it is irrelevant if the dimensions are set in pixels.
(5) Apply any image correction. filters, etc.
(6) Save image to desired directory. PSDs are fine, but remember that layers increase file sizes.
If you are going to do pans/scans, the image will need to be larger than 720 x 480.
If I have a lot of images to process, I find it faster to create a new image (720 x 480) using the Film & video preset in the NEW dialog box, paste the new image (it will assume the same properties of the blank image), size, and then save. Reset for the next image by dragging the history pointer back to before the PASTE action.
The one tip that I would add is to script the still images first. Decide which ones will be just the Project frame size, and Copy all of those to a separate folder. The ones with pans, into another folder. If you have several levels of pan, then another folder. As I treat each image as a unique entity, I might have several folder for the exact re-sized dimensions, as some will require more, and some less.
Then, with the instructions above, create an Action. From File>Automate to Batch, you can call that Action on the entire folder, and also set another destination folder, if desired (my way of doing it). Then just let it go. In moments, all of the re-sizing, color space and PAR corrections are done. You can change that Action, or just create another to accommodate the images that will be panned, and repeat. I can process 100's of image in less time than it takes to finish a cup of coffee.
Then, back in PrPro, Edit>Preferences>General, and set your desired Duration. Import and drag to Timeline. If you need to adjust the Duration of some of the images, it's easy, but if you start pretty close to the necessary Duration, you'll save some work. Last, reset the Duration to what you normally use, should it have been changed for this Project.
All four of the posts were helpful but these last two tied everything up and also provided some very valuable shortcuts and significant time savers. Thanks for the help

Looks like the forum worked, as it's supposed to. Hope that all is working perfectly for you now.
