It's not being 1440x1080 that's the killer but the interframe compression scheme (and pull down has to do with frame rate not frame size). Basically with HDV there are only 2 frames per second that are whole images. All the other frames in that second are interpolated based on those 2 whole images. That is a lot of math to do on the fly which is why things like HDV, XDCAM, AVCHD, etc., are processor hogs and every time you make an edit you destroy that frame cadence which the computer then has to rebuild. An advantage though is very small file sizes. The fact that HDV runs at the same data rate as DV is pretty amazing if you think about it.

In intraframe compression schemes (ex. DV, DVCPro HD, ProRes, AVC-Intra) each frame is stand alone and that is why, in part, they require less process power to work with. A downside is these codecs tend to have larger file sizes compared to Interframe codecs.

Two images per second? I'm buying an FS100 with AVCHD is that all I'm getting is two Mickey Mouse images per second, Lethal?! Then the Ki Pro is correct if I want to have a good base file, right? (I hope so.
