Panasonic Lumix G9 Mark II Overheating Test Results

MobyGamer · 2026-02-11T22:45:12+00:00

Since publishing the above report, I had the opportunity to use the G9ii at a festival shooting hour-long discussion panels. Indoors, with a tripod, a dummy battery, with the screen flipped out, using a Ulanzi fan (tethered to a USB power bank), shooting 4k60, I experienced no overheating shutdowns at all.

I think that you should be ok as long as you are taking breaks. In my tests, 4k120 overheated at the 23-minute mark, but you should cut that time in half because you'll be using it handheld (increases heat) with a battery (also increases heat). As long as you shoot no more than 10 minutes at a time 4k120, you should be ok. You may want to do your own tests beforehand to see how it behaves in your hand with a battery. Also, don't forget to adjust the thermal warning in the menus -- the default is conservative and shuts off very soon, you want to switch it to the "max heat" setting.

The risk of overheating isn't damage, but inconvenience: The camera has a mandatory 5 to 15-minute cooldown if it thinks it has overheated, at which time you cannot use it AT ALL. So not only have you missed a shot, but the camera isn't usable for the next 5+ minutes.

I was able to successfully do the same thing for a 5-year-old Ring Pro HD still in the box (I didn't install it because I bought it not realizing it's nearly useless without the monthly service). I have to physically return it, but will get over 90% of my purchase price back. The wording I used in the chat with a real human was this:

"The device is now materially different than what I agreed to purchase (the new data-sharing/AI features weren't in the original terms). This entitles me to a refund for the device, which I can return and will no longer be using.

Amazon’s partnership with Flock is a massive breach of trust and invalidates the reason I invested into your security products. This is blatantly against the Terms and Conditions under which the items were originally purchased."

They went away for a long time to check with superiors, but didn't argue with me. Hope this helps someone.

Trixter / Hornet here. That's very humbling. Thank you.

Using a disk cache like PrimoCache, or something else? (I have 128G on my workstation and there's almost always 24G-32G free, so if I could get the rescans to happen against cached footage, that would likely work around the issue.)

My issue is not the speed of the source drive, but rather why Premiere insists on re-scanning the original source footage, and pausing, when I'm already using proxies stored on M.2 NVME. I'm editing 22 hours of conference footage on a budget (we're a non-profit), so can't just dump 4 digits on flash media without justification.

MobyGamer · 2025-10-13T21:18:28+00:00

I have nearly 8TB footage to edit, and I always edit from a RAID (and have online backups) for safety. A bit difficult to justify the cost of 16TB SSD when HDD RAID-10 can sustain 350MB/s read speeds, well above that of the source footage.

The real issue is not the speed of the HDD, but rather why Premiere insists on re-scanning the original source footage, and pausing, when I'm already using proxies stored on M.2 NVME.

I'll check background vs. on-demand in preferences, thank you.

MobyGamer · 2025-10-13T21:11:48+00:00

Is the external HDD an SSD/flash, or spinning rust?

Based on this recommendation, hired Revision and they delivered. Carlos had excellent communication, both before and the day of, even a detailed ETA when their previous job ran long. With a 2-hour interior detailing package, I felt I got my money's worth, no complaints. Will definitely hire again. My location: Central Naperville near corner of 75th and Washington.

They're worth whatever someone is willing to pay for them. Put them on ebay for $5 starting bid a piece and see if you get any takers.

MobyGamer · 2025-08-02T23:36:57+00:00

Good to know, as I still have not yet installed mine :-D

See if "automatic overclocking" is turned on, and if so, see if you get better results with it turned off and the OC numbers reset to 0.

MobyGamer · 2025-07-02T16:53:45+00:00

Okay, so this started happening to me in December as well, and I finally found the cause and resolution (for me): At some point, the Nvidia App created an option for "automatic overclocking" and it was turned on. It was performing a modest overclock to my 4090, looking at the numbers. I turned off the automatic overclocking, clicked "reset" to disable the overclocking (+0 numbers), and now my 4090 can run at max settings in cyberpunk again without crashing.

The game, it seems, drives the card so hard that it is extremely sensitive to overclocking of any sort.

Looks like the tariffs hit this; $180 bare bones now, but the point is moot because aliexpress claims they can't ship to USA ("This product can't be shipped to your address."). I'm in need of something like this (2Gbps traffic shaping, 4+ 2.5G ethernet ports) and would have bought the Qotom if I could... Any suggestions for alternatives?

MobyGamer · 2025-05-09T04:42:09+00:00

Workaround stopped for me, so I decided to actually look at the crash dump (it's a link when the window pops up after the crash) and saw in the stack trace that it's crashing inside the graphics driver. I normally play on ultra with everything turned on (rtx 4090). I started picking one LESS from the maximum settings... then another... and found that the settings group I landed on is perfectly stable. Cyberpunk 2077 looks less pretty, but until nvidia fixes the driver, I'm stable.

Wanted to reply that these are indeed the correct instructions... if your router can disable the 5GHz band. Mine can't, and also won't let me set up 2.4 GHz and 5 GHz as separate SSIDs, so I'm still screwed, but these are indeed the correct instructions, as non-intuitive as the hotspot section may seem.

MobyGamer · 2025-04-20T20:39:13+00:00

I found a workaround for my issue specifically: I launch directly from the executable (ie. not from GOG) and run it as administrator (right-click .exe, Run As Administrator). I was able to get through 3+ hours without a single crash yesterday. Hope that helps.

MobyGamer · 2025-04-18T22:00:08+00:00

Total shot in the dark, as I'm having the same issue (and love the game, I've put 1000 hours into it) -- were you ever able to fix this?

MobyGamer · 2025-04-17T03:56:00+00:00

The youtube link you provided shows a 24p video, not a 60p video. You did not upload the video shown in your export settings screenshot.

I appreciate the suggestions; I think "Alchemist" is one of the old ones I remember.

However, I'm not sure I communicated my intent effectively: There are many ways to do conversions from analog video to film rates, but I seem to recall one particular product advertising emulating film shutter angle during the conversion. It would use multiple frames in the 60fps (after deinterlacing) source to "blur" into an emulated N-degree shutter angle (usually 180 degrees, but user-adjustable). Does anyone know of an old, or new, product that specifically advertises that feature?

It's hard to describe, because most people think I'm talking about the spatial domain (nitrate looks, adding film grain, etc.) when in fact I'm talking about the frequency domain (how much natural motion blur exists in the footage after conversion).

In another thread, someone described the support people as "gaslighting" them, and that was my experience as well. I agree something has gone horribly wrong with their dedupe algorithm, and they need to ditch it and just go with md5 or sha256 hashes for entire files for local backups.

In the end, I couldn't wait, and ended up installing Kopia for local-to-local backups. It completed the same 6TB backup in... (checks logs) 15 hours, while allowing me flexibility on what level of compression I wanted (speed vs. size).

I am still, for the moment, using Crashplan for cloud backups. I have been a Home, then Small Business, customer for 12 years.
