No : In my experience every tool is not really replacable, especially good fluid heads and motorized sliders.
Yes : from time to time there are tools or techniques that become in fashion and are been overused for some time. There are videos that consist with 85% or more with drone shots, same when the cheap Konova's were in fashion a few years ago, gopro before that, you name it.
Sorry I wasn't clear - I meant replaceable for certain actions such as a long dolly shot in an interior where a gimball could do a better job than a short slider ( or even a track) and a motorised slow pan (depending on the gimball) may do a better job than a fluid head and be easier to operate by an inexperienced operator. To be honest I'm not too informed as to how much pan and tilt motion control you get with modern gimbal setups but theoretically they could do these moves. I do know how hard it is to get smooth and steady movements with even a good fluid head and that a good fluid head isn't cheap.

Yes.
Why?

Just now, Grimor said:
In fact, now with electronic gimbal, if you are in a hurry, you can fake a slider shot or a crane shot with very decent result.
Yes and you are not limited by the track length of a slider either. Also I believe they do very good panning shots as well. so a ( good) fluid head can be left at home.
-
Sliders - if you need one then make sure it's smooth. This in reality means either motorised control or some kind of motion control like a flywheel or Edelkrone's friction attachment. I think though the popularity of 'slider-shots' is on the decline which is not a bad thing as they were often used to add something of interest to a bad shot and have now become a cliche and as has been said by someone else their use in 'moving through a space' shots has been replaced by Gimbals.

Color science
In: Cameras
'Colour Science' is the systems used by manufacturers to interpolate missing colour information that their sensors can't capture. The Red Green and Blue colour filter arrays ( CFA's ) on sensors determine how accurate the colour capture can be on a sensor with stronger colour filters enabling better colour fidelity however stronger filters mean that less overall light is getting to the photo-sites which reduces sensitivity so manufacturers are always playing these 2 things off against each other. As photosite sensor size goes down due to smaller sensors and higher density's the situation is getting worse but obviously better algorithms are at work trying to interpolate missing colour information. On top of that if you are using an internal Y'CbCr codec where there is reduced colour information in the first place even with a 4.2.2 codec and worse a 4.2.0 codec you are left with not that much colour info to work with. RAW which is RGB is obviously better here. Now most people are not too bothered about differentiating between slightly different hues of green in foliage but our eyes and brains are programmed to be extremely sensitive to even the slightest changes in skin colour so getting interpolated colour decisions wrong in this area even by a very tiny amount will lead to huge apparent differences in skin tone quality and people liking or hating a particular brand's 'colour science'. Canon's approach seems to be one of it knows it can't get it accurate so let's make it pleasing and give everyone a nice suntan.

I have to work with too mutch tracks and clips and i get lagged with my cpu at 100% and my gpus practically do nothing lol.
Are you generating optimised media and using the render cache feature? If not then Resolve will not use the GPU much. Resolve uses the CPU for playback and it will struggle with highly compressed media.

Any intelligence is welcome As I have only just made the switch to resolve.
Depends on the individual setup as to what works best. Watch the resource monitor while it performs particular tasks but the key to Resolve performance in IME with H.264 and other highly compressed codecs is to generate optimised media and use cache rendering and for this you need a good GPU.

My GH3 had pretty mediocre resolution for an HD camera.

Smallrig cage preorder shipped today should be here Friday.
I ordered one last week - good quality products and very reasonable prices.

IBIS is not a panacea. It is different than lens IS or a tripod.
I like some lenses to have IS for run n gun and what not. It is very interesting that you suggest the cheap Tamron, how good is the IS? And the touch focus?
The NX 16-50S is 2-2.8f, so it is wider, equally fast in the same focal lengths and a lot more tele, while its stabilization is very very good. 18-35mm is very limited for run n gun.
IBiS can create weird warping effects at the frame edges with wide lenses. It's really a stills feature to prevent camera shake.

It's not 'that' hard to do a proper test using test targets that differentiate resolution from sharpness. From what I can see the Canon lacks the resolution of some other 4k cameras which may or may not be a bad thing but it doesn't try to compensate for this by adding sharpness you can't disable which is absolutely a bad thing. Has anyone heard of the Nyquist theorem which states ( if I can recall this properly) that you need 2x the sampling rate to create the final resolution so if a 4k sensor is sampling at 1:1 it can't be the same resolution as one that is down sampling from a larger number of pixels. We are too caught up in HD vs 4k etc based on just the pixel numbers but if we used a resolution based standard as I think some broadcast organisations do like the BBC we would find that many so called 4k capable cameras are not able to attain resolutions required of that standard. The Canon R, BMPCC4k, GH5s which all sample at 1:1 are highly unlikley to be able to do this but very likley to be able to create very good HD footage when resampled down. Obviously no one out there in the world of Youtube celeb testing culture is on to this at all and even the manufacturers are happy to say their cameras are 4k just by the number of pixels rather than any resolution measurement.....

Not sure that is correct. The Studio version can exploit multiple GPU's where the free version is limited to a single GPU.
A good article on hardware options for Resolve can be found here: https://www.pugetsystems.com/recommended/Recommended-Systems-for-DaVinci-Resolve-187/Hardware-Recommendations
And this for a good comparison of GPU's using real world video editing scenarios: https://www.pugetsystems.com/labs/articles/DaVinci-Resolve-14-NVIDIA-GeForce-vs-AMD-Radeon-Vega-1213/
If you're not bothered about Premiere, the AMD graphics cards are a little cheaper than the GTX series and still a good option.
Yes sorry I got confused with the OP asking for multiple GPU use. Resolve should use the GPU for rendering if it's configured correctly but I think playback is CPU based. I've spent ages optimising the various settings in Resolve to optimise performance while watching the resource monitor in Windows.

seems like we might have some new speedboosters coming soon as vigneting is pretty strong on all of them
Pretty insignificant to slight on all of them apart from the x64 I'd say - wouldn't call it strong at all. I'd not be in a hurry to change my EF-M2.

BATTERY JAM
I read this yesterday and have not had any issues with the battery jamming for the two weeks I've had the camera.
But last night, on the first real shoot that I've really used it on, the battery jams! And I couldn't get it out (battery also randomly died when it said 85%!) and missed some of the action. Luckily, I still had the GH5 and quickly swapped over my lenses and microphone and kept shooting. But man, not cool. Not when I was thinking of making this my A-Cam for all one-man-band documentary or lower budget commercial work.
Battery is still stuck in the compartment.
Andrew - seen any videos or reports of how to get the battery out once it is jammed in there? Definitely getting external power (the Tilta cages + power look fantastic), but still need the LP-E6 batteries to work. Obviously.
That's bad news. Just thinking aloud here - if the P4K draws too much power the battery may swell and fail even if not exhausted leading to these 2 problems.

Free version. Still wondering I should get studio version with a free p4k or try to fish for a code or dongle somewhere...would it make a difference?
Yeah I checked that first but if you go for their advice you quickly go into five digit territory....
Only the Studio version can exploit the GPU.

P4K, X-T3 or EOS R. I'm going crazy with this choice.
Or A7III, GH5, GH5s....

The photographers who buy a Z7 will change their white balance and other picture settings all the time.
Why would videographers be any more likely to change picture settings than photographers?
Most (serious) photographers will be shooting RAW so picture settings are irrelevant (apart from WB to ensure ETTR is accurate). Videographers need to get more right in-camera as there is less room for adjustment in post production with compressed codecs

do they have similar run times as the originals ?
I'll test them next week and report back

How about this;
Not strictly 'alternative' but I just got some Neewer brand (which work well on my GH5) LP-E6 batteries and they show the battery % and voltage on the P4k. They are also dirt cheap on Ebay at <£10 each!

Benro is good. Have been reliable for years.
The older E-Image were really crap, impressive for the money at starts, completely fallen apart after a year or two (depending the use). I am reading better reviews for the newer ones though.
I decided that my next one will be tue Sachtler Flowtech. I am pondering about the Ace XL head or the FSB6. I am not even sure I need something good as the FSB, but the Ace feels cheap to the feel, and use. It all depends on my next camera buy. If I am buying a bigger camera (C100mkIII) then I should go for the FSB, If I am buying just the pocket, then the Ace should do the job.
Edit: not friend of Manfrotto. Some are ok for the money though.
@IronFilm it is 133$, just buy it already!
On the other hand, I am just _ _ that close to bite the bullet for the CS-1M!!
I've got the Flowtech 75 and it's amazing. It's so quick to set up and adjust the height it changes the way you work and it's got incredible stiffness and torsional integrity for using with a fluid head. I've also got the FSB4 but although it's very well engineered it's fluid action is not the greatest and could do with another notch up of friction if you want to do smooth pans with longer focal lengths.

Yeah but this is not the only camera that has Dual ISO. The GH5s, the Varicam, EVA1 to name a few. Surely someone on here has experience using them to hint at what to expect on the "in between" ISO's?
Single or Dual ISO the same thing happens when you move off the base/native ISO - you loose DR. Look at any DXOmark DR test graph and see DR vs ISO. The strategy with a dual ISO is ( and has been widley reported) is it's often better to go straight up to the higher base ISO than push the lower base ISO. Also in stills ( RAW) it's also a strategy to keep the ISO at base and underexpose then push the file in the RAW developer.

Not editing 4K and also coming from the Stone Age but recently got a standard msi x299?!? 1080gtx and ryzen 2700 and only 16gb ram. My resolve system fine tuning seems to still lag but it is lighting fast rendering stuff (for that it hardly uses any gpu). It looks like you'll need gpu umpf for more nodes, nr, ... while scrubbing and live playback. other than that my gpu seems to be idle pretty much all the time.
Do you have Resolve Studio or the free version?
10 hours ago, thephoenix said:oh ok i thought it was to be the same gc, but if they can be different then even better yes.
do you know if all MB accept that ?
this guy is putting almost everything on hard drives
Some good advice there. Don't get hung up on his HD setup as he obviously needs a seriously large amount of storage for his work. Most MB's have provision for dual GPU's as this is a common gaming setup.

From the looks of it, shoot in nothing but 400 or 3200 ISO. Why even have those other ISOs available if they produce such gross looking highlights?
They only have gross looking highlights if you overexpose your footage by a ridiculous amount ( 3 stops in that test) as once you move off a base ISO your DR drops so clipping is inevitable. On any camera it is unwise to move off base ISO for this very reason but at least with the P4k you get dual base ISO!
-
Interesting and BTW I always use the 'overwrite' option in the formatting app as with the quick one I get write errors. It does take a long time to do as well so not ideal if you are in the middle of a shoot and need to rotate cards quickly and obviously no good if you don't have a laptop with you.
Panasonic GH5 - all is revealed!

Anybody used V60 cards to record with the 400mbps codec. Theoretically it should be fast enough but.......
