How does the slow motion effect work?
This is a playback effect. Recording video with the TRV900 always proceeds at the standard rate of 60 fields or 30 frames per second (although in progressive scan or slow shutter, some frames are duplicates). In playback mode, when you press the “SLOW” button on the IR remote, the frame rate is slowed to 1/3 normal using a field interpolation mode. This interpolated mode, providing a very smooth slow-motion effect, goes out through the analog ports (s-video, composite, and IR LaserLink). A more jerky slow frame mode goes out via firewire. If you want to use slow motion video in your computer, it is better to slow it down in your NLE software- unless you have an analog capture card, which can capture the smooth slow motion just as if it were regular video (which technically, it is). The slow-motion video has lower spatial resolution due to the field interpolation. (Film cameras can run the film at higher speed when shooting, for normal-resolution slow motion, but there is no video camer
