IIRC GU started to give importance to overheating just recently.

https://artlist.io/voice-over Imagine the blow the voice-over community receives. Then I keep reading comments like: yes but the human voice is inimitable and there will always be room for those who want that unmistakable touch. Bullshit

GU covers you 😉

Sony practically doesn't give a shit about overheating. In fact, it is now a trademark. It seems here in Italy in the summer you can't use the camera at home.

The names of these cameras are chosen by Satan himself. Damn them!

Are these manual focus shots? 😉

I'll have a tattoo with this link 🙂

On a underwater image forum we are debating on this. On YT there are countless tutorial and examples on its use for underwater photography but zero for underwater video. So far nobody showed up with some feedback...

I see a lot of wildlife photographers use it successfully. Could you point me at some example? No polemic at all, I'm trying to understand its use underwater. I've seen some video of Mark Smith that could be nearly impossible to film without such AF. Of course none of us knows what the hit/miss ratio is...

There are some video examples too

I partially agree. As I just wrote, the difference in the very latest generations is the deep learning algorithm and the dataset it is trained with. Recognition of dogs cats trains and motorbikes has nothing to do with CDAF and PDAF. Probably Sony and Canon were more advanced in their implementations or their algorithms were better suited to work with PDAF/DPAF. Unfortunately I find very few videos on the capabilities of animal eye detection on video (not photo)

Yet there are hundreds of videos showing how animal eye AF on land works smoothly on Canon and Sony cameras. But this has nothing to do with CDAF and PDAF, it depends on the data the algorithm was trained with. AFAIK algorithm deep learning data are embedded in HW so it is not possible to improve recognition via firmware update.

One last consideration for underwater use and then I won't bother with underwater any more. I am very curious to try continuous autofocus with the PDAF in water. All these videos always refer to Face Detect (and cats dogs birds). The algorithms are trained on these subjects by machine learning. What happens with fish? There are plenty of videos on Sony, Canon and Nikon in which they use the animal eye AF function without any problems and it seems to work perfectly. but these are all photographic tests. I'm very curious to try it out on video.

The scenarios can be very different. If I have the camera on a gimbal I have always tried to be hyperfocal, never attempted to use CAF with the cameras I have had (all contrast based). There is always a moment when you can lose focus and you are screwed. Maybe with PDAF it's different and you can be safe. In other more static scenarios I have always used single AF and then worked manually with focus peaking. If you then have a manual lens with a nice soft dial, it's fun and just takes a bit of practice. In fact I hate Lumix lenses with focus by wire. Only in the latest lumix cameras and only with some lumix lenses you can set up linear rotation otherwise it's a nightmare. Underwater you work hyperfocal as much as possible or in manual via focus peaking. But the cases in which it is possible to do this are very few. Only cinema cameras and cinema housings allow you to work with manual focus reliably, but we are talking about kits that exceed 20K euros. Normally the focus ring on the housing demultiplies the revolutions of the lens focus ring. You turn the focus ring three times and the lens moves the focus by 1 cm. impossible to use it outside macro shooting.

I am beginning to develop an allergy and even hatred toward everything I see on YouTube. What a bullshit title. People who have never filmed shit other than cats or begonias in the backyard. I, with my GH5, am delighted with its performance underwater and on land.

Guys I'm with you but a BBC doc is not "run & gun". Quite the opposite.

I don't remember, maybe "text". This is the screen

Just to slightly derail this thread... https://vmi.tv/blog/learn-help/is-4k-or-6k-enough-do-we-even-need-8k-or-more/ Long and wise article. Excellent final mention of BCC documentarians who is a particular case that seems to contradict the rest and confirms the small reign of Red cameras (although in some BBC behind-the-scenes I have seen Sony popping up...)

I realized that also mediainfo gives this info. I was using the wrong visualization. Everything is inside the Panasonic Semi-Pro Metadata Xml tag and based on the visualization I get a cluttered or more clear view. I discovered I have ISO too. Very useful.

On DFD cameras single AF it's the only reliable method to aquire focus and then manual or hiperfocal.

Other than "see it" or opening in Resolve, is there a program that allows you to tell from the metadata of the file if the clip is in vlog? I was opening vlog clips with the stainless MediaInfo and in the metadata I can't find anything. In fact I only find rec.709.

And from what little I've been able to see and hear, at least here in Europe, DoPs who work exclusively in film are some of the most reactionary and traditionalist people out there. That is why these over-excitements about GH7's ARRI-certified LUT make me smile a lot. It is something that will not touch real film productions at all. Maybe I expect some real use for high end advertising and TV productions and of course all the wannabes but real film environment is pretty much "watertight" In that sense, even Red acquisition supposed motivation to put a foot in the movie business is a gamble

Yes, all new cameras have IBIS. I think we should wait until they complete the renovation of their entire line to see a more specialised camera as the GH5S has been

Joking aside, it will get really interesting if (and when) Pana introduces an ARRI-certified LUT in the next S1II or S2.

The best part was the ball scratching at 1:36" 😄
