Best quality still photo for TV display
The quality of my parked full screen stills will be one of the most important aspects of my DVD. I plan on creating with composition setting 720×486, D1/DV NTSC (0.9). The 11 animated movies will go to Premier to be time lined and soundtrack added. This will then be saved as an Mpeg-2 to go to Encore for authoring. The end results will be shown on large screen flat panel display and home Televisions. I am I on the right track here. What size and type of file should my stills photos be imported into after effects.
This is probably the most important question I have asked so for.
If I’m doing something wrong here that won’t give the needed quality please let me know.Thanks

Greetings!
Well, if the project will be mainly used on large (possibly Hi-Def or 16:9 displays) then no matter what, there will be some pixelation an what not because the project (720×486) isn’t “big” enough to give a crystal-clear image. However, if you are just importing still photos, make the 720×486 at 72 dpi (screens are only 72 dpi). YOu can import it at any higher resolution than that and it won’t matter, but make sure its at least 72dpi.
Yet, if you do have motion (panning/zooming) on the photos, then they will have to be larger than the 720×486 frame. The larger the photo, the more you can pan or zoom and whatnot. The resolution doesn’t matter as long as it is 72dpi or greater.
Hope it helps!
Cheers!

But it’s TV! It’s crap for stills! It’s not print! It’s not 1920×1200, it’s 720×480! Ecch!
Anyway, if your stills will be no bigger than full frame of the TV, then they need be no bigger than 720×540. Any extra size and detail will be lost — turned into a finite, inviolate number of pixels: 720×480 on the TV.
(your stills can also be other sizes like 648×486: search the COW for Rick Gerard’s Dr. Strangepixel article to be enlightened)Do a test with different techniques rendered and authored to DVD and test it on various displays, Joey. If it’s as important as you say, you shouldn’t be going into it blind.
You know the programmer’s motto: “test early, test often”.

Yes Thanks Jeff Helps some.
What file format should I save my stills as for inport to after effects?. They are currently PSD’s that I make up to 17 x 26 limited edition prints for art galleries.
What would be the next composition size up for better quality than D1/DV 720×486 (.09) ?
There is a likely hood that this DVD will be shown at galleries.
Thanks

DPI is only really relevant when scanning and trying to calculate the final size in pixels.
photo size (inches) x dpi = image size in pixels
10″ x 72dpi = 720 pixels (OK)
3″ x 72dpi = 216 pixels (not wide enough to go full frame)So you see you have to do some math to find the right dpi for scanning. If you want your image to fill a 720×540 (see other post) frame, do the math:
3″ x 150dpi = 750 pixels (OK)
If you’re zooming in, the zoomed-in area will have to end up being at least 720 pixels wide, so find the width in inches of the zoomed-in area, then do the math to find the right dpi to make that area 720 pixels wide.

Steve,
I have been testing for 2 weeks.
And will only do parts of animation and take to DVD each step to watch on TV, before I launch into the overall project.
Thanks for you help it is really appreciated.
I have displayed photographs for 30 years and this may be the most important project yet. I forsee flat panel displays at galleries becoming a norm. Not the only way but will definately have a place.My DVD created in ProShow gold looks very good. I just want to take the animations further than what ProShow will do.
