Panasonic's GH3 gets more serious about video

There are a boatload of new capabilities in the Panasonic Lumix DMC-GH3 that are bound to please a lot of video shooters, the GH series' core fan base. The GH2 was an expensive consumer camera with some really nice video features; the GH3 is an updated version designed to meet the needs of the indie and pro videographers who somewhat unexpectedly gravitated to the GH2.
It's practically an entirely new camera: new body, new sensor, new autofocus system, new OLED LCD and EVF, new video codec, useful new still and video features, and Wi-Fi connectivity. The body's now dust-and-splash sealed over a magnesium alloy chassis, with a more streamlined control layout. According to Panasonic, the sensor plus the new version of the image-processing engine have an optimized low-pass filter for reduced moiré, an expanded dynamic range with the company's most recent noise-reduction algorithms, and improvements in white balance for more accurate color.
Most notable for videographers, Panasonic took the surprising step of adding a full-fledged high-bit H.264 codec to circumvent the bit rate and frame rate limitations of AVCHD, which was really designed as a playback- rather than capture-optimized format. Now the camera supports up to an 80Mbps bit rate, 1080/60p and 24p, as well as an All-I codec (that's all interframes, with no temporal compression). Other really useful video additions include timecode (both record run and free run, drop frame and NDF), a headphone jack, focus peaking, audio levels control, and clean and uncompressed HDMI out. Panasonic has expanded the slow/fast recording options with 40 and 50 percent framerates.
