The LX3 builds on the 720p (1280x720) HD video capability of its predecessor by upping the frame rate to a much more credible 24 fps (though not the 30 frames per second claimed in our manual). There are also a selection of lower-resolution modes: 848x480 in 16:9 aspect ratio and 640x480 or 320x240 at 4:3, all at a 30 fps frame rate.
The results are pretty convincing and detailed though a touch jerky in places. You also have to be careful of the roughly 3MB/sec that the movies take up. They are stored in the now rather aged QuickTime Motion JPEG format (we'd have liked to see the use of a format with more efficient compression, though Motion JPEG does tend to offer good quality).
You cannot use the optical or digital zoom during filming.
|On-screen information when recording movies is fairly basic - elapsed time and low battery warning. You can use AE compensation and white balance tuning (before you start shooting), but as mentioned above you can't zoom.|
|The Menu button brings up the normal menu but with unavailable options greyed-out, meaning everything is where you expect it to be. The video resolution options are dictated by the position of the aspect ratio slider on the camera lens.|
|A helpful screen is displayed if you try to switch to 3:2 aspect ratio. (There are no video modes for 3:2, which isn't unreasonable since there are no sensible output devices).|
|In playback mode a thumbnail of the first frame of the movie appears when scrolling through saved images. Press the up arrow to play movies.|
|When viewing movies a set of controls appears in the bottom left corner of the frame allowing you to play, fast-forward and rewind and pause the movie.|

The LX3's lens, as well as being impressively bright, also has Panasonic's Mega O.I.S optical image stabilization built in. As with previous models, it offers two main modes. Mode 1 attempts to stabilize the image the whole time the camera is in record mode, while Mode 2 waits until the shutter button is pressed. The LX3 also has an extra, 'Auto,' mode that uses Mode 2 when the lens is at wide angle and Mode 1 to offer a stabilized preview at the telephoto end of the zoom where camera shake is more likely to make composition difficult.
Our tests (conducted at 52mm equivalent zoom at a distance of around 2 meters) suggest that Mode 1 generally gives better performance, rendering around a 2-stop advantage while Mode 2 provides around 1.5 stops. However, Mode 2 appears more effective at very slow shutter speeds.
