Mmm... no, no. The camera records a JP4 that is (must be) converted to DNG. In this case, they're using adobe standard for the sequence of still images. That means, the camera can record footage in RAW - exactly as if they were sequences of images in RAW taken from a SLR Photographic camera. That's what it's so cool about it. Cinelerra does open DNGs, but it's so CPU intensive due to debayer that it becomes impossible to edit them directly (which would be excellent, btw), so what I imagined would be that turnaoround. You wouldn't need a firewire, because the footage is recorded directly at an hard disk.
