I'll be the first to agree that dclouds images aren't quite the test I'd hoped for, but in terms of being "flawed" the only issue is that the iris is set a bit too low on the ISO5000 results. That will not affect the relative noise levels in the blacks between the ISO levels, and you could draw conclusions about such even if the camera was capped!OK, well Im not here to convince you. I'd suggest that you use the camera and see for yourself, before basing it on flawed images.
But that's not what is being seen. We're seeing the base noise level increase substantially more than 1dB with upping the ISO - just as may be expected with any comparable camera. So no big deal at all. Up the ISO, and the noise comes up as well if everything else stays the same.
Noel, you've been loaned the camera by Panasonic and put a lot of effort into making lengthy tests. You've claimed "native Dual ISO" as one of it's main plus points. It's not just me you are presumably hoping to convince, so if you do think dclouds images are "flawed" then surely it is in yours and Panasonics interests to do such a test (up the ISO to 5000, close the aperture 3 stops, leave all else the same) to your satisfaction?
And now - and, by now, I mean, September, 2015 - with C300 MK II being out and delivering a similar performance for $16,000, one has to wonder about Varicam finding its niche.
If the spec sheet delivers the visual equivalent of a higher end equipment - and we've seen the performance of digital video improve from next to nothing in the late'90's to a 65mm film quality of today - then it's inevitable for some higher priced models to be squeezed out. I'd bring up the audio example again. In the era immediately preceding the electronic, a hybrid pro guitar like a Gibson L5 from that era was beautiful from every aspect - from sound it produced to craftsmanship that produced it. Then a cheap Fender Telecaster comes out along with cheap Fender guitar amp and, within a decade, jazz is out and rock is in and four guys playing some cheesy English* audio products conquer the world. (* they used the US made guitars too)I think everyone on this forum knows how much I've enjoyed working with C300's over the past 3 years and am very much looking forward to taking the MKII for a spin, however - its not aimed at the same environment, different workflows etc etc - theres a lot more to a camera than the spec sheet.

I think if anything they've been pushing the "hype" marketing too much, without getting solid information out. It may work at a more consumer level, but for the market it's aimed at I believe such is counter-productive. As just one example, what Steve posted earlier in this thread - http://www.dvxuser.com/V6/showthrea...ricing&p=1986488764&viewfull=1#post1986488764panasonic needs to get their act together and push this cam in marketing. Especially with well established cameras slowly eating away their lunch
Anyone seriously interested in a camera in the Varicam class is pretty certain to well know that a 4K Bayer chip won't - can't - deBayer to give full 4K resolution. It's nonsense. There is nothing wrong with a 4096x2160 chip per se - but claiming this camera is doing the impossible is wrong, and arguably counter-productive. It just gives rise to what I believe the police etc call the "and what else ....?" feeling, where if they start to find inconsistencies in an statement - even if seemingly inconsequential in themselves - it gives them cause to ask "and what else" may be false about it.I asked about resolution and he told me that the chip has a surplus of photosites so that after debayer it gives exactly 4k resolution, not 3.5, not 3.7 but 4k. How, I don't know.......
And to Steve's point about HFR at 4K, it's not quite that simple though, is it? At the very least I believe it's only achievable with the Codex RAW back, and it's my understanding that the 120fps 4K mode is only to RAW recording. And since RAW and the Varicam means uncompressed only, then at 120fps we are now talking about truly phenomenal data rates..... So it may indeed do the 120fps, but apart from the Codex cost it means a massive workflow hit.
Eh, I don't recall a single slow motion clip in "Godfather".4x greater frame rate on the Varicam at 4k - that puts it into a completely different league.

Canon lists C300 MK II as having 1,800 lines, making it it ... eh, 3,200 x 1,800?Anyone seriously interested in a camera in the Varicam class is pretty certain to well know that a 4K Bayer chip won't - can't - deBayer to give full 4K resolution.

Something in the 80 Mbps range?I'd always assumed it would do 120fps internally AVC Ultra - otherwise it really would be an over-priced piece of kit!!! This site http://pro-av.panasonic.net/en/varicam/35/workflow.html has a table listing it as doing 120fps in AVC-Intra 4kLT - whatever that is! Steve

Slo-mo is fine for action films, which are largely beyond the scope of middle of the range cameras. And, for wild life, one can find suitable equipment also. (and, btw, I love wild life .... for about 10 minutes at a time)?????????????????
Interesting - I found this ( http://www.redsharknews.com/product...-35-gets-a-dramatic-boost-via-firmware-update ) via a bit of googling. I was originally told by a dealer that the 120fps was only available in RAW via Codex. It seems that was true when he said it, but this mode is new via a firmware update.I'd always assumed it would do 120fps internally AVC Ultra - otherwise it really would be an over-priced piece of kit!!!

The normal quoted rule of thumb for a Bayer sensor is that it will give luminance resolution of up to 80% of the basic sensor dimension. Other sources say 75% is a better figure, the 80% being where it's tailed away to nothing - but let's not split hairs.DLD said:Canon lists C300 MK II as having 1,800 lines, making it it ... eh, 3,200 x 1,800?
The question now is what exactly "AVC-Intra 4kLT" is! It seems to be more heavily compressed, and as yet unsupported by NLEs etc - and I couldn't even find it on Panasonics official AVC-Ultra page!
.
Having both iso800 and 5000 is veryuseful. I would attest iso5000 is really good.V
And that's partly why I find this business of the dual ISO odd to put it mildly. I've learnt over the years that if something seems too good to be true, it normally is, and this seems to fall into this category. I'd just like to get to the bottom of it. If the performance really is as stated it just begs so many questions, and not least is why even bother with any ISO800 mode if the ISO5000 mode is just as clean?

It's far more complicated than that, and Panasonic have changed the nomenclature meaning at least twice. Barry clarified many aspects a while back and you may like to read what was put then - http://www.dvxuser.com/V6/showthrea...camera&p=1986296922&viewfull=1#post1986296922 - and the following posts.I thought the new higher bit rate update of AVC Intra was going to be AVC Ultra??? I'm lost....as, unfortunately, is Panny I think![]()
Firstly, I completely agree with your second sentence. I've said from the start that I see the Varicam as pretty good in it's own right - but just not deserving of some of the overhyped remarks that have been made about it. I maintain that OVERALL it's roughly comparable to an F5, with both advantages and disadvantages compared to that. That's no problem, it shouldn't be seen as negative - it's just saying the glass contains 50% rather than it's half empty. I'm saying the Varicam and F5 are both pretty good, but neither as good as (say) an Alexa or an F65.dcloud said:i know you need to be skeptical before you could believe its claims but why be sooo negative?
The only disadvantage they have is the really steep price
I make it about 160Mbs? The number of seconds must be 1340/24, which would give a file size of 160*1340/24 Mb, and divide by 8 to get MB - so would give about 1,117MB - pretty close to 1.13 GB.dcloud said:1340 frames @ 24p is 1.13 GB
i cant do the math![]()
