To XL1 Frame Movie Mode, yes. I don't know about the slow shutter modes. And note that you'd only want to do this if you want your transitions and effects to have the same temporal resolution (or lack thereof) as Frame Movie Mode footage. For best smoothness, leave your rendering at Lower Field First. Cheers, Adam Wilt Interpolation - Adam Wilt > So line replication isn't used and "interpolation" is.

Unfortunately the interpolation used *is* a slightly more sophisticated averaging filter. You (or the hypothetical computer) can fill in the missing details because you're looking at the line *as a line*, an object with knowable (or guessable) properties. The poor dumb filter chip in the camera hasn't the horsepower or the time to parse the incoming video and make decisions about scene content (a nontrivial task). All it *can* do is look at the pixels above, and the pixels below, and guesstimate the color and brightness of the synthesized pixel in the middle. You and I see that there's a line there with some missing data. But that's because you and are hardwired by evolution to see patterns. Camcorders need a few more years to get that clever!
