Please take care when using your DSLRs for video. Often the sensors are not adequately cooled for long term usage as a video camera (>30m). You have the potential to damage the sensor if it is not designed for continuous use and doesn't have proper thermal protection. Newer cameras will shut down if they get too hot, or have limits to how long you can run in video mode. Stackoverflow discussion: https://video.stackex…

It is the actual recording mode that generates the heat. Transcoding, putting stuff in the buffer, saving to storage, etc. With the HDMI-out, you are just sharing the viewfinder and offloading all those tasks to your computer, so heat is not really an issue unless your room is extremely hot to begin with.

The sony a5100 is really popular with twitch streamers right now because it will run all day in this mode and you can turn off all of the UI elements to get a 'clean' output. You don't get all the cool cinema features but you do get a camera that is better than just about any webcam.

Switching to a "real" camera has been such a huge, huge improvement for me on video calls all day, I machined a custom vesa mounting arm to hold my camera in just the right spot. https://lightroom.adobe.com/shares/088254b7439745b982784c0a4...

Thanks for documenting that; 'twas a real joy to go through.

Am I the only one with strong objections to using Zoom as a verb? Putting aside the fact that it's already a verb, which courses plenty of confusion, I can go along with using Photoshop as a verb, because it is objectively the most powerful and widely used tool with a very long legacy. But Zoom is a clunky insecure mess with impressive, but not nearly leading market share. Is this really who we want to be gifting the…

I think you have to accept it. Zoom was in the right place at the right time. Now it's a verb. The good news is that once a brand becomes a word, it doesn't really mean much about the company itself. I blow my nose into CVS brand Kleenex. I have a Xerox machine made by Canon. I've captured many a "Kodak moment" with my iPhone's camera. Windows users routinely "Google it" by asking Cortana, which actually uses Bing. A…

You are right, Zoom was a right place right time thing. Doesn’t bother me other people saying it, but I’ve never used Zoom once, nor do I have any plans to, so I don’t see it making it into my vocabulary.

I don’t get it either, but Animal crossing was already one of the most beloved and best selling franchises in Nintendo history, so the pandemic didn’t really do much there, except give people more time at home to play and crack the code faster!

Could you elaborate on how it's been an improvement? I always thought it'd be overkill for regular business calls.

In a word: bokeh. I'm running a 50mm f/1.8 lens on a full-frame sensor. My job requires me to interact with external customers, sometimes in a pre-sales role. Appearances shouldn't matter, but they do. Anything I can use to present a more professional and "expert" image is a win for me.

“Let’s zoom” means just that; let’s get on Zoom and have a meeting. I’ve never had somebody say, “Let’s Zoom,” and contact me on FaceTime, Google Meet, WebEx, or another service.

It works(ish) but worked better before most of the major players locked virtual cameras out with updates. Issues with unsigned code, so then some folks started unsigning apps smh. Still works with Chrome based version of several tools, and it’s cool when it works, but definitely a bit on the fragile side. The Canon software has the same limitations and just lets you use software from a perhaps more trusted source dep…

And what is/was the point of locking out the virtual cameras?

Making it a touch harder to use Snap Camera and other silliness, as well as Xsplit, OBS or other video produced sources, for “Zoom bombing”.

Correct me if I'm wrong, but the 30m limit is due to some taxes or regulations on "video cameras", right? Edit: Yup. https://petapixel.com/2012/05/21/30-minute-video-limit-in-di... > At present [2012], digital cameras' video cuts off after 30 minutes to avoid them being classified as video cameras (which attract 5.4% duty because they are considered to be video recorders

Reminds me of those light trucks that get ripped apart to create passenger cars. EDIT: I had it backwards. The tax is on trucks and it gets circumvented by importing them as passenger cars: https://en.wikipedia.org/wiki/Chicken_tax

Nah, light trucks are in a whole other category (or exempt, I don't know) in "CAFE" standards, so that's why you see so many SUV's in America.

Old wives tale. Even the stackoverflow answers say as much. Most of the thermal ramping occurs in the first five minutes and then stabilizes after cache is exhausted. As all these dslr’s allow you to record 29m50s videos back to back all day long it’s also indicative that it’s not a big enough issue in returns to warrant addressing in their firmware. As you’re not writing to the SD card, hdmi passthrough should yield…

Economic Partnership Agreement between Japan and EU had signed that abolishes the video camera tax. Most camera brands are in Japan but I don't know how many cameras made in Japan.

This Japanese article describing the agreement especially for cameras. I can't find English articles like this.

This is the original agreement text that's too long didn't read.
