YouTube quality issue ?

YouTube quality issue ?
Yes the ad free experience is a plus, but until years ago I browsed Vimeo finding video and interesting content, something like YT, now I use it mostly to share my work with my buddies on our projects. They can even download the original file while on YT you can't. Before the "switch" I could upload 5GB per week and during the years I uploaded tons of video. Now they changed policy: they removed the 5GB weekly limit and added a global 260GB limit. But they didn't reset the counter. I fiound myself half full but I know of users that found themselves immediately without space so basically forced to delete a lot of material, upgrade or leave. IDK if I will renew it. In the meantimecopied all my public videos on YT.

Yes buy I couldn't care less while I pay 100 USD per year for a service. I pay the same as an American member. Moreover they didn't communicate anything before the switch. I received some vague update announcement but nothing explicit. Thousand of customers discovered it later by themselves. Imagine that if I use Vimeo for my work, I cannot see most of my overseas customers profiles. Unbelievable. So IMHO stay away from them

YouTube quality issue ?
As Chris wrote, YouTube adapter the bitrate based on your connection and preferences. On the phone and on desktop you can change that ar various degrees. On the phone, by default without wifi it uses a low resolution. You can change it on the fly or on the app preferences but basically you have low/high while on desktop you can choose resolution. Sometimes the auto function doesn't work so you have to force the correct resolution. I've been a Vimeo Plusmember since 2007 and the service has gotten much worse over the years. The company that owns it changed many times, and they've had several legal fights with copyright owners. In recent years, they've completely given up on being a choice instead of YouTube. They've focused on giving services to people who use it for work. The last big problem happened a few months ago. Because of copyrightrproblems, it seems they failed complying with EU privacy and copyright rules, they completely separated users in many European countries from the rest of the world. Now, I can't see what my friends around the world are doing anymore. They did this by lying to users and without telling them. Even though I pay 100 dollars a year, when I asked why, they told me they aren't allowed to tell me. Forget them! It's shameful. And it's done badly, very badly. Think about it: in the app, I still get messages about video uploads from people I follow, but I can't watch them neitther Incan ses their profiles, and the search doesn't work. Darn them! 100 dollars a year. At the end of the year, I won't pay for it again because of this.

How to best store images on long trips in the world of 4k?
Yes, absolutely true! Usually I would grab the first cable I find at home but actually most of them are cheap cables designed mainly as power cord. hence some real data transfer cable is paramount.

Yes, take in account that your "speed" will be capped to the lowest device of the chain. So regardless of your lightning SSD NVME, if you have a slow usb/thunderbolt interface, you will stick to it

[documentary] Underdogs - National geographic
Yesterday I watched a new five-part series titled "UNDERDOGS," narrated by Ryan Reynolds, This five-part series, a collaboration between Reynolds' Maximum Effort and Wildstar Films, is set to shine a spotlight on the often-overlooked creatures of the natural world. It promises to reveal the unique survival tricks, bizarre mating strategies, and surprising superpowers of these "unsung heroes." Expect never-before-filmed scenes and stunning cinematography.

Canon R5 Overheat / Nauticam Housing
Did you set Auto Power Off Temperature: high? Set Overheat Control function to “ON” (default). IDK if 4K@60p in CLOG IPB can be recorded on a class A SD card. Usually CFExpress cards overheat more than SD.

Canon R5 Overheat / Nauticam Housing
Let's be serious, the R5 is a fantastic camera, even used in big-budget productions. I'll buy it 😉 Many scenes from Ballesta's latest documentary about the mysterious circles in Corsica were shot with Roberto Rinaldi's R5, and he even records in RAW. Of course, the water temperatures are around 15 degrees Celsius there, but I know several people who use it professionally for land-based shoots, and since Canon released the updates, they've never had issues. Just search on the net. Just out of curiosity, how long are your uninterrupted clips?

AA Battery : wich are the best for strobe
hahaha On al lighter note, you reminded me that about twenty years ago, I worked for a while at a greyhound track (I maintained some accounting software). What always made me laugh was that when I went in through the back entrance, for the staff, the sign on the door said: "Beware of the dog." 🤣

List of Underwater Monitors
I realized that I mixed data from O.G. Shinobi and Shinobi II and Nauticam housing. The "old" Nauticam housing is not available anymore. The Shinobi II is 30% thinner and lighter so the whole housing becomes 80g positive. It's worth highlighting the features of this new Shinobi II monitor. It has 1500 nits compared to the previous model's 1000, but the best part (and almost unbelievable to me) is that through its USB-C port, it can show all the camera's main settings and even control the camera completely from the monitor. Plus, it can charge the camera using the same cable. It uses a beefy Sony NPF battery Amazing, right? Okay, now pretend you didn't read that, because underwater, the monitor only connects via an HDMI cable. So, none of those cool features work. It's a shame Nauticam didn't try to figure out a dual cable solution (maybe through the M24 port) to use these features. I guess I'm just a naive dreamer 😇 Ultimately, if you want to save some money, you can buy the less powerful version, the Shinobi GO. It has everything except the remote control via USB. Ciao

Canon R5 Overheat / Nauticam Housing
That's really strange. Also, the aluminum housing should transfer heat almost right away, even if 28 degrees isn't cool. I see you're using an ALL-I (Intra-frame) codec. This method compresses each frame one by one. You won't get small file sizes like with other methods, but the files are super easy to edit because they're not compressed much. "Classic" codecs are all IPB, meaning the algorithm saves and looks at one frame (a picture) every so many frames. For the frames in between, it only keeps the differences, which saves a lot of space. The files you get are much smaller, Then, depending on how many predicted frames (the rebuilt ones) are in between, it's called Long GOP. When you edit, the software has to do the opposite process and rebuild all the frames. It's a power consuming process done by your GPU. It depends on you editing system. here a simple explanation between them. Going back to your ALL-I codec and files, the problem is that they're huge and put a lot of stress on your entire camera I/O system, from the processor to the CFexpress card. Try to film some minutes and immediately remove the card. You can barely touch it, it's hot as hell! Long story short, what I'm trying to say is this: the difference in bitrate (how much data is used) and the stress it puts on your card and how much heat it creates, between ALL-I and IPB, are not small at all. From Canon's website for the R5, I found these numbers: 4K (59.94p/50.00p) ALL-I: around 1000 Mbps 4K (59.94p/50.00p) IPB: around 340 Mbps 4K (59.94p/50.00p) IPB (Light): around 170 Mbps IDK you use case, but I would immediately try switching to the IPB codec at 340 Mbps. That's one-third of what you're using now. Even on my vintage GH5M2, I have ALL-I codecs, but I've never used them because I'd always be buying storage. On the other hand, I've never felt the need for them because the IPB codecs are excellent. If you use CLOG, you directly get compressed H.265 10-bit 422 files. Ciao

AA Battery : wich are the best for strobe
The comments in this thread made me curious about the difference between the two types of batteries. Since I don't feel like doing anything this century, I asked ChatGPT 😝 I'm not responsible for errors or omissions 😇 Both Eneloop white and Eneloop Pro black AA rechargeable batteries are high-quality NiMH (nickel-metal hydride) cells, but they’re designed for different usage profiles. Here’s a quick summary followed by a more detailed comparison: Feature Eneloop (White) Eneloop Pro (Black) Typical Capacity 1900 mAh 2500 mAh Recharge Cycles Up to 2100 cycles Up to 500 cycles Self-Discharge 70% charge retained after 10 years 85% charge retained after 1 year Continuous Discharge Current ~1–2 A without rapid degradation Up to 3 A or more for high loads Min Operating Temp -20 °C -20 °C Price More affordable More expensive 1. Eneloop White (Standard)Typical capacity: 1900 mAh Excellent cycle life: up to 2100 charge/discharge cycles Very low self-discharge: can retain charge for years in storage Best for low to medium drain devices, such as: remote controls, wireless mice and keyboards LED lights, alarm clocks, basic sensors 2. Eneloop Pro BlackHigher capacity: 2500 mAh Lower cycle count: up to 500 cycles Slightly higher self-discharge (but still excellent for NiMH) Designed to handle higher discharge currents, ideal for: camera flashes, gaming controllers, motorized toys high-drain LED lights, professional audio gear Discharge Current (your key interest)Both are solid performers, but: Eneloop Pro cells are built to handle higher continuous and peak discharge currents — they’re better for power-hungry devices or short bursts of high current (e.g., camera flashes). Standard Eneloop (white) cells can’t deliver as much peak power but are more than sufficient for most everyday devices. ConclusionChoose Eneloop White if you want longevity, reliability, and a lower price — ideal for general-purpose use. Choose Eneloop Pro Black if you need more power and higher current output, even if it means fewer charge cycles and a higher cost.

Canon R5 Overheat / Nauticam Housing
I know that the well-known overheating problems with the R5 were fixed with firmware updates. They basically removed most of the first limits. It was quite embarrassing for them. Here in the Mediterranean, I know people who use it only for video and have never had problems. What temperature is the water? What resolution and codec do you use?
