I'm using iMovie 08 with an HD camcorder. There is an option in the size settings to deinterlace. The video I make with a lot of motion seems fine to me without deinterlacing checked.

What are the pro's/con's to checking this box?

I'm assuming you are talking about exporting.

When exporting, you create interlaced content for television sets and I believe DVDs too since the MPEG2 files are probably interlaced. If your destination is a computer then deinterlace. You'll find the picture tends to look better on a computer screen when you deinterlace.

I've also recently read somewhere that deinterlacing can generate smaller files. I haven't tested that though.

If you don't know then leave it...

check the box if you shot the video on a progressive camera or on film, otherwise if you don't know what you are doing you'll ruin the video and have to reexport it and waste time.
