Maybe we need a topic for best camera and/or settings for run-and-gun ;)

@kendalloz I would love to hear those GH4 run n gun settings. I don't have that many camera wishes, but I am afraid the camera still does not exist: pro video (Nd filters), large sensor (DOF, low light) super stable, easy to work with, pro audio xlr)

@tommy There is an exposure mode available on the LCD screen when in MOVIE mode on the top dial. Use the appropriate function button on the back of the camera to bring up the settings display and you will find it. Choose auto exposure and the camera will do smooth exposure changes. I just tested the GH4 in this mode with continuous focus turned on and was pleasantly surprised at the results.

@caveport Please be more clear, because when top dial is set to M(movie), and the menu> exposure mode is >M, there is no auto ISO available (it starts at 200) The auto exposure is only available in A, P, S . But in S mode the aperture (steps, not gradually), so only A,P.

@tommy The M mode is manual photo mode. You need the movie camera icon on the top dial. You should then go to the main setup menu and choose page one of the movie settings and select Exposure Mode 'P'. Then use the 'Disp' function button on the rear of the camera to bring up the lcd display of frame rate and other settings. You will see a section for ISO. Use the touch screen to select ISO and the Auto option is available.

lumixmaxgh3 Sorry but, is my impression or the details and color of GH3 in low light is better than GH4? Someone they has both, have noticed something else that is better the gh3? lumixmaxgh3

This was my first impression as well, but the more I use the GH4 the more I like it better than the GH3

Interview on the GH4. Great info here on master pedestal vs the s curve.

@soulkeeper 1/200s will keep you closest to 180 degree shutter and so is usuall recommended. Seems to give the best sharpness.

@dckyoto which negates the easy opportunity to drop to 1/40th when shooting slow-moving scenes that need a bit more exposure.

@WalterH The shutter speed is still controled by the rear thumbwheel, it's just displayed in degrees not seconds. It's really good as you just set to 180 for most shots. Want more light? Increase shutter angle or vice-versa.

@Vesku An 8-bit H.264 file encodes luminance Y-values in the range of 16-235, regardless of whether the camera sensor outputs 12 or 14 bits of RGB data. (UV color data is handled similarly by the H.264 encoder.) Before encoding each frame, the GH4 applies tone curve settings and scales its sensor data to an 8-bit equivalent range, in either 16-235 or 0-255 scales. Many people assume that this 8-bit RGB scale should be the same as the 8-bit YUV scale used internally in H.264 files, but they are actually two different color spaces. It is the H.264 decoder's job to reconstruct the original 16-235 or 0-255 RGB color data from the 16-235 YUV data encoded in the H.264 file.

@Vesku DSLR's such as Canon and Nikon use the 0-255 range to encode H.264 video. Older camcorders use the 16-235 range. The GH4 gives you a choice, allowing you to match it to other cameras you may be using. With a modern 32-bit video editor, however, it makes no practical difference which scale you choose, as there are no significant rounding errors in mixing footage from differently scaled cameras.

@Vesku It's a subtle point, make sure to understand that the YUV values written into the H.264 files are not the same data as the RGB values read from the image sensor. They are two different color spaces, which may be scaled differently in each camera model.
