how does it render w/o motion blur?
if it is significantly faster, you may want to try and ‘turn down’ the motion blur. in cs3 you can adjust the number of samples used in motion blur, open the comp settings, click the advanced tab, and at the bottom are the comp motion blur settings. you can adjust the shutter angle, as you could in other versions, but now you can adjust the number of samples, and reducing that value should help reduce render time, if it is motion blur that is bogging down your system.

there is a good tutorial on making good, simple slide shows at videocopilot.net, scroll down the tutorials page, it’s towards the bottom.
i believe you can find it here at the cow too, if you search for slide show, it was created by andrew kramer.

check out videocopilot.net, scroll down the tutorials page to the graffiti tutorial.

if the interlace issues are within details of the photos/images then there photoshop action that can help called deflickerator. you need to put it in the photoshop actions folder and then load the action from the actions palette in photoshop, then just play the action on the images and re-save them. the action selectively blurs areas of the image that can cause interlacing issues.
however if the problems are on the edges of the images, then you may need to try and soften those edges. you could try to create a mask just inside the edes of the image, then choose feather from the mask options and set to a small value.
can you post a still image or short clip showing the problem? it would be easier to make suggestions to help you out if i could see the problem.

[Angie373] “720 X 480, square pixels with a ratio of 4:3. He wants to insert my comp with some footage he has which is at 720 X 480 NTSC DV square pixels”
i’m a little confused too… or maybe your boss is a little confused.
720×480 isn’t a 4:3 ratio, it is a 3:2 ratio. and, as far as i know, ntsc dv only comes in one size and that’s 720×480 with a par of .9.
i’m not sure of the workflow that is being used here, it is possible that all the 720×480 dv footage has been converted to 640×480 (or possibly, 720×540 – although upscaling interlaced footage can be problematic) making it 4:3 with a square pixel, and now matching footage is needed to put it in that timeline. but an easier and more common workflow would be to keep everything dv native 720×480 (par of .9) and then, at the end render as 320×240 sq px for the web.
you may want to know what his footage actually is… ask to see it, or to get a sample. check the size… if it is 720×480, it can’t be 4:3 and square pixel; if it is 640×480 or 720×540 then it is 4:3 with a square px… either way set you comp to the footage that he is working with, if it matches his footage, then it will fix his workflow and be consistent for the final output.

you can easily just change the frame rate to 59.94… d5 at 720 will work with that frame rate.
what i’m a little unsure about is the pixel aspect ratio… since i don’t know what the par is for d5, i would use a square pixel comp (1280×720, square px)… it’s always easier to scale it down if it is a 1.3 par (960×720, 1.3 px). and, as gets pointed out here often, some effects are not non-square px friendly anyway.

yes, ae cs3 will use all cores if you enable multiprcessing in the preferences and you have enough ram to feed those cores data. adobe recommends 1gb per core (the ram used per core can be set in the memory pref, by setting the max ram cache size).
i believe this 1gb recommendation is in addition to the ram you will want to allocate to ae (usually you’d like 2-3gb) and the operating sysytem or any other applications you’d like to have open.
so getting around 8gb of ram wouldn’t be a bad idea. that being said, i have a 4-core macpro with 4gb ram and it runs well. when i enable multiprocessing with default ram settings i can only use an additional 2 cores (so 3 total), and i get a notable performance boost. oddly enough, when i decrease the ram cachce to use all four cores, i don;t see any change in render speed (i hope that adding more ram would change that, but i can’t say for sure)…

in digital ntsc your pixels are not square, they are refered to as .9 (1 would be square) or non-square. what this means is that your pixels are 10% shorter than they are wide.
you can work in square pixel in ae if you’d like, many actually prefer to, but your comp will no longer be 720×480 it will need to be 720×540. also note that if you want to render something for broadcast, tape or dvd you will need to make it conform to 720×480 size (or 720×486) and a .9 pixel aspect ratio.

i did a little more testing…
i created a comp that would benefit heavily from opengl accelerated effects/features. the 8.0.1 update definitly adds opengl acceleration for previews and renders… if you have multiprocessing enabled, there is a slight pause prior to rendering or previewing, versus having multiprocessing off.
the message in the info panel was partly incorrect during a render (not preview) using opengl. opengl was being used (despite saying not supported), but multiprocessing was disabled in order to use opengl. i think the same process happens in preview renders, where multiprocessing is disabled, and the pause prior to render that i’m seeing is due to the disabling of multiprocessing.
so now the question will be to use opengl or to use multiprocessing…. it will depend largely on your system but also on your project.

first, did your ‘export’ or ‘render’? you should render, by using make movie or add to render queue from the compostion menu. you’ll have more control over your render options and output module.
if you had footage in your comp, and the fields were interpretted correctly (it sounds liek they were, if it looked good in preview), then in the render settings all you should need to do is set the fields to the correct dominance (same as footage).
how are you viewing the render? are you seeing jaggy edges on a broadcast monitor as the clip plays or on a computer screen? if you are seeing jaggies on a computer screen, then that is most likely due to a computer screen not drawing the image with scan lines. you will need to view your clip on a tv or broadcast monitor for the interlacing to draw correctly, and not look jaggy.
