Thank you for the heads-up.

So what was the bottom line? That it can overheat when shooting 120p video for a long time?

Please, which sane person shoots 120p for a long time ?

Matt Irwin posted as well -- similar tests but using power delivery. Here is a summary of the results from the 2 vids:







As I and so many others have posted many many more Z8 will be in folks hands starting this time next week -- since both Ricci and Matt Irwin posted the the details of the tests they ran each of us could take the time to replicate a few of these tests and validate their results -- this is the scientific approach. THEN we can pick our own real world scenarios for how we wish to shoot, with the cards, lenses, supports we will use and see what the results are.

For me Matt Irwin's tests were close to how I will use the Z8 for VID in a rig -- but NO ONE I know would plan to just shoot with a single long recording. So Ricci's tests where he formatted the card are close to real world where we shoot and swap out cards and batteries after each set up to allow footage to be off-loaded and backed up.

Some folk have to shoot in high ambient temps -- these are the plague for digital CINE bodies -- which have large heat sinks, active cooling AND Red Shooters remember having to use cold gel packs as well. I would not surprise me that like any camera without active cooling any very high res/fps data demanding format/codex will overheat both card and body quite quickly. SO bring multiple bodies to set or plan for cool down between set ups.

OR apply cooling solutions as well -- It is easy to add a quiet fan into a rig -- would this help YES -- by how much -- it needs to be tested. I agree with Matt I - using a d-tap to a V or gold battery will reduce the heat generated from an internal battery - many use a dummy battery and deliver power this way anyway. Now with the Z8 we have an extra port.

Ricci says honestly he worked only at low 21 °C and without intensive AF with long lenses or any other conditions leading to push up internal temperature.

So he deals only with what M Granger araised : the maximum duration of capturing video and forgot that the main uissue is not there : the game is not only at duration of clips which is only unconfortable but of the excessive and repeated heat itself.

I.e. push up ambiant temperature up to a contiuous air 36°C in mean and 45° to 50° in direct sun light add a continuous work of the CPU with AF active and using long telelenses so the issue to anticipate becomes not only selecting memory cards but what is the highest temp that the electronic of the camera and particularly the image stacked sensor can acept before dammages.

We really need more significant testing in real hot conditions to tell us the limits of such a middle class camera.

Are you doing wildlife videos? How many people are doing the sort of videos you're suggesting?

I watched most of Ricci's video and the answer was it's mostly a non issue. He used small cards that are likely to run hotter than larger ones. Formatting them in camera like he did is also likely creating more heat than actually recording.

Nobody is doing an hour to a small card like Ricci did. Test it to a large fast card if you want

Thanks for the detailed summary!

All I can say is this makes me feel good about angelbird being solid cards for the money.

Not that I plan on running them that hot but good info to have.

"Middle Class Camera" -- what do you mean ? a camera with the capabilities of a Z8 must surely be considered above average -- upper middle class or even upper class should you need to use such a classification.

But yes we need more folk to perform tests to repeat the Ricci/Matt tests and then go on to their own situations. BUT please be very explicit about your set up, the cards you use, ambient temps and the shooting parameters you are using -- all of them -- eg High Quality -vs- Normal quality 8.3k 60p N-RAW N-LOG uses 60% more storage and appears to have the highest data use requirements. It makes a large difference. So does the High Heat and Normal heat cut off setting.

Let us all collect robust data and present it in a way that others can replicate the tests, validate the results and then design ad conduct their own tests in ways that let others do the same.

I think in the end, everyone's experience will vary slightly, and these should just be taken as guides as what you can expect. Some people might get an extra minute or two, some might only get 10 minutes. I think what people are mistakening here is the recording time that Nikon advertised (up to 90 minutes) as a promise (when in fact in their footnotes and documentation say "possible" and "up to") implying that you could get that, but you may not, based on your conditions (and those conditions obviously being ambiet temperature, power source and/or memory card used).

Just how many car mfrs may advertise a top power output of say 220 HP, but most people will never be able to achieve that (partially due to laws and regulations, among other things). But according to their tests, the engine can hit 220 HP at its peak.
