This same comment on G7 pops up left and right, whether related to them or not, sometimes twice in the same topic. Now, leave me out of your future contemplations and prayers, warrior.

I just opened the old project in Premiere and exported the frame from a timeline to JPEG and TIFF. GH4 got a FW update 2014 autumn which increased the 4k bitrate from 85Mbs to 100Mbs. Before that the banding was maybe more visible. Quote Link to comment Share on other sites More sharing options...

j_one Posted March 17, 2016 Share Posted March 17, 2016 Can I recommend you try editing in Edius if you experience major banding issues? Their pseudo 10-bit conversion actually helps smooth gradients in all my 8 bit footage, especially from my LX100. Danko 1 Quote Link to comment Share on other sites More sharing options...

Their pseudo 10-bit conversion actually helps smooth gradients in all my 8 bit footage, especially from my LX100. My issue is that I want to know if the GH4 fools with colors causing banding and is there some best settings to avoid that. I usually just look my clips without editing. Some players can add dithering to cure banding. I just wonder why GH4 videos has more banding than JPG photos. Is the luminance levels 0-255 but color levels 16-235 or what may causes the limited amount of colors? Is the YUV in general weaker to record gradients than RGB? Is the codec reducing colors to match 100Mbs in 4k? Quote Link to comment Share on other sites More sharing options...
bunk Posted March 17, 2016 Share Posted March 17, 2016 Could your ND filter be the culprit, or lens even. Might show in h.624 and not in raw. just a thought. Quote Link to comment Share on other sites More sharing options...
Vesku Posted March 18, 2016 Author Share Posted March 18, 2016 Maybe even GH4 iso200 looks little rough and noisy because it lacks colors between perfect gradients. Blurred areas are not smooth in GH4 video. Quote Link to comment Share on other sites More sharing options...
Vesku Posted March 19, 2016 Author Share Posted March 19, 2016 I think that Sony RX100 mk4 has less banding in sky in this example than my GH4: Quote Link to comment Share on other sites More sharing options...

Blurred areas are not smooth in GH4 video. For sure. ISO 200 I try to avoid. Same thing with the C100. If you go lower than the native 850 ISO you get banding everywhere. Walls, skies, shirts.

The little increase of noise, fading colors and breaking image is worse than little banding. The banding is not a big issue but I wonder why it is there.

Fredrik Lyhne Posted March 19, 2016 Share Posted March 19, 2016 What ISO do you recommend for the GH4? I think I read somewhere that 320 and 640 was recommended on GH3, is it the same? Quote Link to comment Share on other sites More sharing options...
AaronChicago Posted March 19, 2016 Share Posted March 19, 2016 I believe 400 is the native ISO Fredrik Lyhne 1 Quote Link to comment Share on other sites More sharing options...
mercer Posted March 19, 2016 Share Posted March 19, 2016 Sorry, a little OT, but how do you find out a camera's native ISO... Specifically the G7? Obviously, I have googled it but couldn't find anything. Quote Link to comment Share on other sites More sharing options...

Not sure officially which one it is. 400 looks cleaner though IMO. Quote Link to comment Share on other sites More sharing options...

I assume since the G7 shares its sensor with the GX8, I can search for the GX8's native ISO as well. Either way, I always try and stay below ISO 800 anyway.

I recommend iso200 for video, iso200 for JPG photos and iso100 for RAW photos if there is enough light. Fredrik Lyhne and mercer 2 Quote Link to comment Share on other sites More sharing options...
Vesku Posted March 21, 2016 Author Share Posted March 21, 2016 Here is an example of GH4 iso200 video with lots of skies (not mine). There is something like noise all the time in sky but it cant be noise at iso200 and bright sky. Why the sky is not clean? https://www.youtube.com/watch?v=LuTAF79Lbok Quote Link to comment Share on other sites More sharing options...
