Only some bug fixes. No new features like auto iso in M for video or exposure values visible in video recording. http://av.jpn.support.panasonic.com/support/global/cs/dsc/download/fts/dl/gh4.html

New TVs can play 10bit 4k HEVC videos easily, even at 60P. HDR and 4k bluray is coming. I have watched 10bit 4k 60P video files with my 65 Inch Panasonic TV from SD card and the quality is something I have never seen. Very wide gamut, contrast and clarity and absolutely no banding even with...

I made a quick test. All 4 videos with same exposure and with tripod and the same lightning. Iso 200, NR -5, 4k down sampled to fullhd, no iDynamic or curves or other than profile and contrast settings. 0-255 levels and captures of full levels and uncompressed frames to Photoshop. I adjusted...

What do you think about GH4 noise reduction? I have a comparison of the same clip with NR -5 and NR 0. Other settings were iso3200, natural contrast -5, color 0, sharpness 0. iDynamic was standard and there is heavy underexposing. I think NR-5 is much better. Image is 100% center crops of 4k...

[Anamorphic(4:3)] mode is available which optimizes the settings for 3328x2496 video recording with a 4:3 anamorphic lens.* To convert the footage to a cinemascope aspect for playback, corresponding software and device are required. 1/16000 sec shutter speed can be selected manually when using...

How can I see them? I see only file icons without thumbnail image with 100Mbs files. Windows Media Player cant play them and says "missing codec". I have not installed GH4 cd.

I am having problems with 100-300mm autofocus. My first copy of that lens AF died after one year of use and I got new one from warranty. Now after 1.5 years of use I have the same issue with the new one. When powering on the camera the lens AF sticks and does nothing. If I shake the lens during...

Here is the difference between GH4: 1. 8bit 4:2:0 video ----- 2. 8bit 4:2:2 JPG photo ---- 3. 10bit 4:4:4 RAW photo ---- and perfect photo, downsampled from very big photo

Can I have 4:4:4 1080P ETC if I use 4k and 2x digital zoom? Chroma is then recorded 4:2:0 4k which is the same as 1080P 4:4:4 and the image size is the same as ETC.

If you have that lens you should contact Panasonic service. We may have a FW fix if many people complains. I have heard that Panasonic knows the issue but I am not sure if they are doing something. I have tested 2 copies of that lens with 3 bodies (GH3,GH4) and the OIS vibration is exactly the...

-auto iso in M for video with EV control (EV control for photos too) -auto iso limiter or range for video -every menu item programmable to every Fn (at least video AF, maybe not format) -play- button to right side (FN 2/3/4-option) -AE/AF lock on-off-on-off usage during video recording...

I have thousands of clips which needs stabilization. How can I do it?

Loop recording is interesting. It is now a time machine. AF performance in video recording may be good too. 1:1 4k video for anamorphic - 2880pix vertical res! No raw or better customizing options. http://panasonic.jp/support/global/cs/dsc/download/fts/index2.html

I have GH4 and 14-140 II lens. When I shoot video handheld and try to keep it stationary and steady the OIS is generating rapid vibration or jitter. It shows clearly in 2k and is bad in 4k. I have seen that jitter also with 12-35mm and 35-100mm POWER OIS lenses in Youtube or Vimeo. All my MEGA...
