still images in adobe premiere flicker

I'm having trouble exporting still images into videos in premiere.
they look fine in the preview screen, but once they've been rendered to
avi or mpeg they have a funny flicker that detracts from the final
appearance. things i've tried to get rid of the flicker include.
1 deinterlace the stretched image
2 crop the original to exactly 720 x 480 to ensure it's not a resizing
problem
3 saved in ps with adjustments to ntsc color range
4 i've tried jpegs, gifs, bitmaps of all different bit ratios, tiffs
They all flicker

I feel as if there's a simple step to this one, that i'm just missing
by an inch. I've spent hours trying to solve this, but to no solution.
Help appreciated.

If there's no "reduce interlace flicker" or similar option in premiere (or
it doesn't work), you have to apply directional blur (sometimes called
motion blur). The image flickers because there's 1-pixel-sized vertical
detail, and since the picture is interlaced it is shown every other field
(every 1/50th or 1/60th of a second - on, then, for the same duration,
off). So you have to blur the picture vertically. In Photoshop you'd apply
the motion blur filter, at 90 degrees and two pixels.
