I only make UHD videos with the GH5. I have 2 options in the Settings regarding Luminance: 0-255 or 16-235 for 50p and 8bit 0-1023 or 64-940 for 25p and 10bit Can you advise me which one you would use? But does anything change when watching video on TV? Thank you IIRC, these settings are related to if you plan to broadcast your video over TV. When TV stations process video they only have a range of values that are allowed, they're called "legal" values, and they're a little bit less than the full range of values that the camera can generate. The 16-235 and 64-940 ranges will be within those "legal" values. Computers and YouTube and other online services probably don't care about these things, so if your videos aren't going to be broadcast on TV then it probably doesn't matter. If your videos are being broadcast on TV then you should contact the person at the TV station that you are in contact with and ask them. They should be happy to tell you their requirements if that's important for them. Quote Link to comment Share on other sites More sharing options...

YouTube *does* care about these things, always submit an H264/265 stream with 16-235 setting, or else the video wont look right. kye 1 Quote Link to comment Share on other sites More sharing options...

That's interesting - do they scale the values back into legal, or clip them? I haven't heard that non-broadcast distribution cared about such things.

Chris777 Posted February 9, 2021 Share Posted February 9, 2021 Well I havent tried recently, but in the past they would be clipped because they are out-of-spec. You can check a video by opening it with vlc, it will look “wrong” if its out-of-spec. kye 1 Quote Link to comment Share on other sites More sharing options...
Aquilasfx Posted April 5, 2021 Share Posted April 5, 2021 If I use 4K longGOP 10bit in vlog- l internally, it will save the file as rec709 color space? It will save FULL or limited (video)? I need to know in order to use properly DaVinci resolve color space transform. It ask me color space source and gamut source. Thanks Quote Link to comment Share on other sites More sharing options...

Thanks Unfortunately, the V-LOG L of the GH5 / GH5S cameras is not the actual full V-LOG that the color space transform (CST) was designed to work with in resolve. You might be better off using a Technical LUT to convert the footage to REC 709 in Resolve. Quote Link to comment Share on other sites More sharing options...
webrunner5 Posted July 13, 2022 Share Posted July 13, 2022 Well 4 shots from today on the GH5. Boat House 14-140mm, last 3 300mm f2.8 L FD lens. The one of the Lodge had to be a nearly 1/4 mile away. The Geese one was maybe 200 feet away, people fishing probably 300 feet away. This looks to be a damn good copy. I can see I need a better tripod for this lens. Had a nice carbon fiber one but it weighed a freaking ton, should have kept it I guess. Camera, lens shot with my iPhone 6s plus. Pretty satisfied on my fist real outing with it. Well, it looks like the photos are switch for bottom to top but you get the idea. Have to figure the 300 is actually a 600 on the GH5. newfoundmass and mercer 2 Quote Link to comment Share on other sites More sharing options...
webrunner5 Posted July 13, 2022 Share Posted July 13, 2022 What sort of sucks is the iPhone straight out of the phone is probably the best looking shot lol. And it is a 7 year old phone! Sigh. They are pretty amazing for what they can do. The 14-140 didn't do too bad though.😬 Quote Link to comment Share on other sites More sharing options...
webrunner5 Posted July 13, 2022 Share Posted July 13, 2022 This shot was taken with my 12-32mm Panny lens today. I am telling you for the money you can buy one for they are a real sleeper. And they have OIS in them and are small and light as heck. Like having a 24-70 in your pocket. The Raw looked even better. mercer and kye 2 Quote Link to comment Share on other sites More sharing options...
kye Posted July 15, 2022 Share Posted July 15, 2022 @webrunner5 Nice shots! Getting sharp images of far-away objects is likely to be heavily dependent on the weather - I've spent a lot of time using my FD 70-200mm to shoot the sunset, and when I put it on a 1.4x teleconverter and use the 2x crop mode all you see is heat shimmer. If I use the same setup to focus on a close subject then the image is crisp, so it's not the optics, it's the distance. The combination of 200mm with 1.4x and 2x crop gives an equivalent of 1120mm, which is all kinds of fun to get steady video with. This setup was using the 4K mode so I could stabilise in post because even in this setup there was image shake and I had to stabilise in post - the image shake was coming from the ground through the limestone pillar! webrunner5 1 Quote Link to comment Share on other sites More sharing options...
kye Posted July 15, 2022 Share Posted July 15, 2022 These aren't from the same night as the above, but I'm guessing that these were similar setups, but taking images as a timelapse. Quote Link to comment Share on other sites More sharing options...

Yes, you make very valid points. I always use a tripod with a hook on the bottom and I hang a 1 Gallon plastic jug of water on the hook to help stabilize the shot, and when you are done just empty the water for weight savings., camera bag works also, and lock down every knob there is on the tripod and ball head or fluid head. But that does not help haze or heat waves. A UV filter, or haze filter does help though. People that make a living shooting stuff like that have crazy expensive tripods, heads and so on. But yes, there are times weather wise you are better off staying home no doubt lol. kye 1 Quote Link to comment Share on other sites More sharing options...
