Is there a point and shoot digital camera with optical zoom while recording a video?

Is there a good quality point and shoot digital camera that allows for optical zoom while recording a video? Not digital zoom, which just crops the frame you already have and makes the video blurry and undefined, but optical zoom, which actually zooms into what ever you’re looking at without the blurriness of the digital zoom. Thanks so much for your help :)
Is there a camera with all of the qualities above that is compact. For example, a camera that could fit in a jacket pocket.

you can consider buying Panasonic Lumix DMC-FZ35 12.1MP Digital Camera
# 27mm wide-angle Leica DC Vario-Elmarit lens;
# 18x optical zoom with POWER O.I.S.
# HD movies with 1280 x 720-pixel resolution; AVCHD Lite format
# 2.7-inch TFT LCD screen
