stopping moire...how to?

I'm in the process of building a video montage (least that's what I call it) using a series of still shots which are zoomed and panned to give more of a video look to still shots. Some shots can be rezed to 720x480 no prob but others are not landscape but portrait and have to be fitted to a black background plate of 720x480, so I have a 313x480 pic sitting on a 720x480 backplate. On my 20" tv these plated images are wider at the bottom sort of like a tree trunk effect. Does anyone know how to fix this or is this just a tv aborition?...Also is there any way to fix the video shake that attacks things like venetian blinds etc. I think it may be called moire or somthing to that effect. Any help would help.
 
Re: stopping moire...how to?

The first problem sounds like your TV, unless it looks that way on your monitor as well. The second problem with moire is easy to overcome. You can apply a "reduce interlace flicker" to it, or you can apply a slight gausian blur to the image. You will only want to apply it to the photos that are having the problems, as you will lose some detail.

Thanks Scharky...I'm reluctant to blur the images as they will end up being projected before the critical mass of corporatedum on a 10.5 x 14 foot screen times 2. Of course the moire doesn't look good at that magnification either. are there any other solutions?

The blur isn't as blurry as you'd think and it's a very effective way at blurring moire. In FCP, there's a check box in the motion menu to smooth motion (or something like that). CLicking that will also reduce moire.

Thanks J_Barnes....I'm running premiere 6 and the blur produced by reducing interlace flicker leaves me with a blurred image and no real defeat of the moire problem. I thought there might be some relief in the rendering stage by not rendering to fields or something of that nature?
