Premium Member Peter J DeCrescenzo Posted March 29, 2009 Premium Member Share Posted March 29, 2009 UPDATE 6/10/2010: Vitaliy Kiselev's (AKA "Tester13") "PTool" firmware modification utility software for Panasonic Lumix Micro Four-Thirds cameras (AKA "the GH1 firmware hack") essentially transforms the DMC-GH1 into a whole new camera, image-wise. The improvement is _HUGE_. Plus, the hack adds useful new capabilities in addition to "merely" increasing the recording data-rate. Refer to post #53 for more info: http://www.cinematog...ndpost&p=325618 =========== =========== Panasonic's new Lumix DMC-GH1 Micro Four Thirds interchangeable lens digital camera will record 1080p24 HD and 720p60 HD video in the AVCHD format @ up to 17 megabits/sec VBR (and also Motion JPEG at 720p30), and of course digital stills, too. The GH1 has a 12MP 17.3x13mm sensor (about four times the area of a 2/3" video cam's sensors), full manual and auto exposure & focus controls (using the included kit zoom lens), an unusually high-res 1.44MP electronic viewfinder and a fully-articulated LCD screen, and 2-ch. audio w. ext. input. The GH1 began being sold in Japan on April 24, 2009. The cam sold in Japan has on-screen menus in the Japanese language only. Panasonic US has announced the GH1 will be available in the US by "early June" with a suggested list price of $1,499.95 US including a 14-140mm optically stabilized zoom lens. Panasonic Europe announced the GH1 will also be available there in "June". Here are some external links: http://www2.panasoni...000000000005702 http://panasonic.net.../gh1/index.html http://www.panasonic...6692/index.html http://panasonic.jp/dc/gh1/index.html Frame grab from a reduced/compressed sample video on Panasonic's Japanese website: http://panasonic.jp/...ographing2.html There are many other sample videos on Panasonic's websites. However, please note that most of these videos have been heavily compressed for web viewing and may not accurately represent the best quality video this cam is capable of recording. Videos on YouTube are generally even more heavily compressed & degraded compared to most of the video samples seen on Panasonic's websites. The GH1 records HD video in the AVCHD or MJPEG formats onto relatively inexpensive SDHC memory cards. Here's a link to a table of recording time limits depending on which of the cam's many digital still & motion video modes are in use: http://panasonic.net...y_card/gh1.html AVCHD is supported by a wide variety of modern video editing software -- such as iMovie, Final Cut, Premiere and many others -- running on appropriately-configured computers. Refer to the software developers' websites for information concerning recommended minimum system configurations. In general I'd recommend working with the software's most-current updated version. The GH1 has a HDMI HD video output port. Early users of the GH1 report that it's HDMI port does _not_ appear to support "live" HD video out when the cam is in preview or record mode. Instead, the GH1's HDMI port appears to be strictly a playback-only feature. Playback quality on HDMI-equipped monitors is reported to be very impressive. The GH1 also has a composite SD video output. Live SD video can be output from the cam both during preview and playback. However, the GH1 does _not_ appear to be able to output live composite SD video when the camera is in record mode. Obviously the GH1's lack of any live video output during recording rules out directly-connected external monitoring or outputting to an external recording device while the cam itself is in record mode. However, considering the GH1's relatively low price, its ability to both record relatively high quality HD video and take very nice quality stills, the relatively large size of its image sensor, its ability to use interchangeable lenses, it's hi-res viewfinder & LCD, and the cam's small size & weight, the GH1 seems promising for use in certain video production applications. Of course, the usual caveats apply. YMMV! Notes concerning the GH1's audio capabilities: The GH1 has a small built-in speaker for audio playback, but does not have a headphone jack. Audio can also be monitored during playback from a SDHC card if the GH1 is connected to an external monitor or amp, but not when the GH1 is in recording mode. Panasonic includes a special "USB-to-RCA" cable to get line level audio playback out of the camera, and to transfer data from a SDHC card in the camera to a computer. The GH1's built-in stereo mic is reported to deliver fairly good sound quality, with minimal mechanical sound picked-up from the cam's auto-focus, motion-compensating lens. It appears the audio levels are adjusted automatically by the camera, and early users report that this auto audio-gain feature can't be switched off to allow manual audio level control. The built-in mic will likely be best-suited for ambient sound recording and scratch/reference audio. The GH1 has a small 4-pin jack for connecting an external stereo mic or other 2-ch. audio source. Panasonic offers an option stereo mic for use with the GH1. It's possible a new BeachTek XLR interface may address issues caused by audio auto-gain, as it reportedly does when used with Canon's 5DM2 HD video-capable DSLR, but I don't know if it's been tested for use with a GH1: http://www.beachtek.com/dxa5d.html Other external audio gear might be used with the GH1, such as the Sound Devices MixPre field mixer, but in general they don't have the special AGC-Defeat feature offered by the specific model from BeachTek referenced above. However, like the BeachTek, most external audio interfaces/mixers enable connection of external audio sources via XLR connectors & a degree of manual audio level control: http://www.sounddevi...s/mx2master.htm Quote Link to comment Share on other sites More sharing options...
