Some codecs only work at specific resolutions, and the DV codec is one of them. I’m not sure why you have an NTSC one and not a PAL one, but I think this has come up in the forum before — try doing a forum search for DV PAL or something like that.
Whatever stage size you set in particleIllusion, that’s your output resolution. So if your stage is 1049 x 576, that’s what it is. If it’s coming in to Vegas as a different size, then Vegas is reinterpreting the size based on a different pixel aspect ratio and you need to adjust that in Vegas.
I think.
