While most of the Panasonic Lumix cameras include the function to record videos in 720p AVCHD Lite format, Lumix DMC-GH2 is advertised with further video recording format: Full-HD Movie in AVCHD Format and 24P Cinema Mode with 24Mpbs. These features Lumix GH2 is getting closer to camcorder level.
For the video recording format, you will find AVCHD and QuickTime Motion JPEG with file extension like .mts, .mov. For the recording mode, you can get QuickTime Motion JPEG with 640×480, 320×240, 848×480, 1280×720, or AVCHD in 1920×1080 (24p, 60i or 50i), 1280×720 60p or 50p. The 60i and 60p are for NTSC, while 50i and 50p are for PAL.
While you face problem importing Lumix AVCHD and AVCHD Lite footage to iMovie 8, 9, 11 or FCE 4 for editing and creating your movie, you can use Aunsoft MTS/M2TS Covnerter for Mac as the best Lumix GH2 AVCHD to AIC converter.
