Sony have released a shirt pocket camera that claims to effectively record HD video. I took one along to a Ray Davies Concert to record a tune as a demanding test of its capabilities. I also snapped a few stills on the camera and cut these in. The results are here. Clearly, as often the case, the sound performance falls behind the picture, and with no external microphone socket, this is a significant limitation. If its jerky, try letting the buffer bar fill before you play, the original does play smoothly.
