Heat generated during long continuous recording can cause problems. It not only affects internal components but can also degrade image quality. Effective thermal diffusion is an essential design challenge. By drawing on the expertise accumulated through its many years of developing camcorders, Panasonic has revamped and redesigned the electronic parts arrangement and internal structure to achieve the optimum layout. This has eliminated heat problems in the LUMIX GH3.
When recording the video in MOV, AVCHD Progressive and AVCHD, the DMC-GH3 automatically generates multiple seamless files for continuous recording. During playback, the AVCHD Progressive / AVCHD files are reproduced with seamless, interruption-free continuity. The DMC-GH3 also embeds SMPTE-compliant Time Code either in Rec Run or Free Run count-up methods, which makes it easy to synchronize the multiple video footage or sound source in the post production workflow. Time Code Value can be started at any point of [Reset], [Manual Input] and [Current Time]. Drop frame or Non Drop Frame time code is selectable***.
For high quality sound recording, DMC-GH3 adopts Dolby Digital® for AVCHD Progressive /AVCHD videos and linear PCM(LPCM) for non-compressed video recorded in MOV. In addition to the built-in stereo microphone, the GH3 is equipped with two 3.5mm terminals for an external microphone and headphones to facilitate sound recording.
The DMC-GH3 also features Creative Video mode: Exposure mode and Slow/Fast-Motion mode. In the Exposure mode, four manual video modes: Program AE / Aperture-Priority / Shutter-Priority / Manual Exposure can be selected and they will faithfully reflect your shooting intent, and give you a wide range of video images. The Slow/Fast-Motion mode enables slow-motion (40% / 48% / 80%) and fast–motion (160% / 200% / 300%), all in Full-HD.
Not only full-time AF, AF Tracking and Face Recognition AF are also available. The Touch AF in video recording also lets users enjoy professional-like rack focusing. Just by pointing at the subject, the focus is shifted to it and lets it stand out to attract attention.
*60p(NTSC) video recording is not available in AVCHD and MP4 video recording.
**In the model for PAL areas, motion image can be recorded up to 29 min 59 sec.
***Available in the model for NTSC regions.

All cameras in the LUMIX G assortment adopt Contrast AF for their focus system. Compared with the Phase difference system AF, the Contrast AF boasts higher accuracy when shooting with a bright lens with a wide open aperture.
The DMC-GH3 features ultra-high-speed AF which makes it possible to capture fast-moving subjects clearly. Both accuracy and speed are improved over high-end DSLRs with Phase difference AF with the GH3's advanced Contrast AF system. The camera and the lens exchange the digital signal at 240 fps to minimize the time to focus. Together with the quick start-up and short release time lag, the DMC-GH3 never lets photographers miss fleeting shooting opportunities.
