> The strange video you see at the top of this post was filmed with this setup. One that I actively recommended against to any fellow remoter. Particularly folks who aren’t into photography or videography. It’s cumbersome, complex, and requires constant fidgeting to keep the camera on, obtain a consistent color temperature, or prevent automatic focus hunting due to shallow depth of field.
This is a common theme among people with overly complicated setups: Looks and sounds great when it works, but they're fighting with their setup in every other meeting: Focus issues, automatic power off problems, photographic cameras overheating because they weren't designed for long streams, audio issues as they work to select the microphone they want instead of something else, and so on.
This page recommends two excellent webcam-style USB cameras that won't deliver the professional-looking blurred background images, but they will just work when you plug them in and they won't be full of surprises. That's more valuable than a blurred background or crisp 4K video through expensive lenses when you're just a small H.265 compressed square on someone's screen.
Initially, I've set up my DSLR, through purchased copy of SparkoCam. Continuous video ring light, green screen behind me, nice zoom for proper proportions of face and nice replaced background.
Insert months of tripping over cables, tripod, camera, green screen; dropping video because something on complex chain gave up; the laptop fan running like a jet airliner; and just general pain-in-the-kiester of it all. Now I have a logitech Brio in front of me. Nowhere near as nice, but more than good enough... and I haven't thought of it since I installed it :)
(I still have a small ring light, because lighting is important as the article indicates, for clarity of facial emotions and context )
They do, but you can't do video longer than (insert minutes) because otherwise it would be a video camera.

It's really frustrating, I also cared to set up a decent input, but all of Google Meet, Slack, and Zoom have terrible terrible compression.
Of course lighting is also really important as many cheap cams have sensors too small to do 30fps in low light. Let alone 60 which I think no current video conferencing product does.
The reason I suggest not starting with an SM7B is because this microphone is expensive at nearly $400, and requires high quality mic preamps to get a proper signal out of the mic (often people add a $150 cloudlifter) which adds to the expense.
The SM57 on the other hand is an excellent XLR dynamic microphone, used on countless recordings and live sound applications. It is super durable, and can be purchased used at around $50.
Plus Shure makes an optional $20 foam windscreen for the SM57 called the "A2WS" which helps filter out pops and plosives, and makes the mic look similar to a 7b.
There are many comparisons available on youtube to see if you can hear a $350 difference yourself, for example https://www.youtube.com/watch?v=PFba93OLLig
I'd avoid the super cheap Behringers, M-Audios, and the like. These will typically be noisy and have essentially no resale value in the future, while quality brands hold most of their value and can be re-sold later if/when upgrading.
My use case is remote guitar lessons. I need an instrument in and a microphone in. My Microphone is the Audio Technica ATR2100 I bought a few years back.
After doing a lot of research, I bought the behringer with the agreement that if I use it enough and it’s a limiting factor on what I’m doing, I will upgrade to the UA Volt II when it actually is on sale and not just pre-order. But the limiting factor in my signal chain is the compression on Skype… so I just went with a cheapie interface it gets the job done. There is some noise I pick up when monitoring with Sony MDR-V6’s and I need the volume up pretty high to get good direct monitoring levels, but overall testing has gone well.
Again, if I had a more important use case or I was recording, I’d spend for the focusrite or just wait for the UA Volt II. But this is “Streets Ahead” of just using a laptop mic with my electric guitar unplugged (or to my headphones) because my kid is sleeping. The other option I had was just to swap between microphone and guitar, but that made lessons awkward.
It's a different approach, and has more buttons/knobs, but provides a high quality and free solution supporting rooms and multiple participants. Can be incorporated into OBS as well for recording, streaming etc.
I've found it to be a useful tool for connecting with musicians remotely.
Rather than microphone quality, the differences between the samples are primarily attributable to microphone position and technique: specifically, being 10 cm from the mic produces something people like better than being 60 cm away. The main issue with the MacBook mic is that it's inconvenient to get close to it.
The advice to get a boom to make it easier to bring an outboard mic into optimal position without strain is excellent and highly practical, IMO.
The one big quality outlier is the Airpod Max sample, which exhibits compression artifacts and rolled off high end (and low end, but that matters less). It is substantially worse than all the other options. (It probably has worse latency, too.)
The iPad Pro sample isn't great either, probably because the mic is off-axis when speaking into it from a natural position. Again, the degradation is primarily a result of suboptimal microphone position and technique rather than component quality.
This made me wonder, apearantly I (I would say we, but you did not) can hear the distance something is recorded at, separately from the volume. How cool are our ears.
What's surprising to me is how good the laptop mic is, despite the hurdles working against it.
In my case, I live in a one room Studio Loft with my wife, who is in meetings all day and is quite a loud speaker. Pretty much any boom/desktop Mic I've tried is also really good at picking her up.
My current workaround is to use a unidirectional headset microphone[1], But would love other ideas, as cable management is a bit cumbersome.
The SM7B seems to be listed as Cardoid not Supercardoid?
Get the mic close, disable auto mic level in zoom, and set the gain on the mic to be loud enough only while youre speaking.
[https://www.sweetwater.com/store/detail/MV7K--shure-mv7-usb-...]
It's a bit better than my AT2020. But I find that in order to get my Gain down low enough so that my partner isn't too distracting, I have to be right on the Mic.
Which isn't a very attractive look over video....
The pickup pattern is going to be mostly right in front of the mic, with the best rejection from the rear. Keep in mind the mic will also pick up reflections if there is a wall close behind you.
So ideally you’d sit in front of the mic with no wall or a wall at an oblique angle behind you, and your wife across the room directly behind the mic.
Turns out we're moving to a new home, so I anticipate this issue will get solved with walls and doors in the future.
And generally every single mic recommendation I give in the linked post has a cardioid pickup pattern which is precisely what can help isolate stray noise in places with louder environments. Software like Zoom will do the rest of the work for you depending on how aggressive the noise control settings are. Zoom is surprisingly good at eliminating echo, feedback, and other non-speaker-voice noises from the mic signal.
Stray far and wide from omnidirectional pickup patterns in microphones because they will unfortunately be far too sensitive to environmental noise. This is also true with many noise-canceled mic/earbuds combos which cancel noise for the person wearing it but not for the people receiving the mic audio recorded in the noisy space.
Of course, if the author gets the North American salary instead of the European one, while living in Paris, then things might work out financially.
I moved in the deep suburbs of Paris because rent and apartment prices are a no go for a single income person, even in tech.
And as someone who never moved away from where he was born and also never lived in the really expensive part of the city, it might solve the problem of many more people just moving here to work, whereas they would prefer living more remotely. I would love to stay here, for example, not just because of work because I've lived here all my life and like it.
Also your (and the author's) mention of a studio confused me for quite a bit, we'd never call anything 30m2 a studio where I live :P

I lived in rural land before moving in the Paris suburbs in order to land a job. In some ways I am glad I had to. It opened me to so many new stuff. I would not imagine enjoying my twenties in rural land personally. The trade of housing space for commodities, almost car free living and infrastructure is currently worth it for me. Maybe I will go back rural in my 30's now that full remote is gaining traction. Or maybe not. I get your point though.

The nomenclature we use in France (IIRC) is studio for a single room, and then 1 bedroom, 2 bedroom, etc.. no matter the floor size. How would you call it? And where do you live so we have context in naming things? :)
I think you’re mixing two points I’m making. None of the point about offices in city centers and expensive neighborhoods relates to my personal experience. It was a general point about the futility of office-obsession on the part of companies, which was particularly bad even for startups in the Paris area back in 2015/2017. Hopefully it’s better now. But I remember people looking at me like I was mad for saying remote was non-negotiable.
May I ask the reason of work was not the one? I know I would not want to go back in the country side for now, given the limited public transportation and medical infrastructure out there.

Sorry if I misread or interpreted things too quickly. From what I am witnessing in the area, you currently can :
1 - Go full remote in the country side and have your pay reduced. Job security takes a hit too, because the job market is not "hot" like in the US. 2 - Agree to come to the office 2/3 times a week and go live in the suburbs (or stay in town if you can afford it and enjoy it)
I currently using option 2. Maybe I am missing g other options.
Do these three simple things to make your video better:
1. Get a laptop stand that raises your laptop so your eye level is towards the center of the screen. Not only does this improve ergonomics, it improves the positioning of the camera for video.
2. Get a lamp that you can move the head on and point it at the wall behind the laptop (assuming it's white-ish in color) to provide reflected back light at your face from behind the camera, and then add as much ambient light as possible in the room emanating from the corners (smaller rooms are easier to light). You don't need anything fancy, although yes a ring-light is probably "better" you can get by with cheap floor lamps from Walmart and some "daylight" color temperature bulbs.
3. Make sure all the lightbulbs in the room are the /same/ color temperature, whatever that happens to be, but preferring "daylight" if you can.
Just these changes will MASSIVELY improve video quality on conferences, and for most people wouldn't even necessarily require buying anything additional except possibly light bulbs (you can makeshift a laptop stand, and move lamps from other rooms if it's an especially important meeting / interview you are preparing for).
For audio, nothing beats a microphone on a boom, but any good quality USB headset with a built-in boom microphone will get pretty close, so don't sweat this so much. The main thing is that you should NEVER be taking a call using the built-in speakers and microphone in your laptop... it sounds horrible and picks up a lot of noise.
The only laptops I would never use the camera on are Dell laptops that inexplicably chose to put the camera near the keyboard so it's staring up the person's nose the entire time.
There's been a vacuum in high quality web cameras for a while, most of the market has just been junk.
A good microphone is totally worth it too. I'm not sure why after over a year of pandemic and remote work many are still using their 720p webcam in a dark (sometimes backlit) room with the crappy built-in mic. If you're making good money invest in a decent set up - with mostly remote comms, it matters more than you think.
2. Also the bandwidth of our video conferencing service (eg. Zoom)?
The camera quality is good (a little short but can be put on a riser), the audio quality is good. The noise cancellation is good.
Does someone know why this matters?
None of his samples show him with headphones, so what are they used for?
The A6000 is among the most reasonably priced and dependable mirrorless cameras that you can use but it’ll still set you back around $1000 new and you’ll need a lens, and an acquisition card (Elgato Cam Link), etc. This is why my post recommends against mirrorless cameras for a huge majority of even tech-savvy folks.
Specifically because A/V tech savviness and computer tech savviness are far from wide overlaps in expertise.
My idea is that I could also plug the mic directly into the camera. I like how the A6000 looks and I only need it for recording so I wonder if there’s some slightly cheaper mirrorless that can produce similar quality.
As for some of my learnings:
Cameras: Using an external camera is important, looking downward into a laptop camera isn't very flattering to begin with, and it makes me uncomfortable. As with an ill-fitting suit, it makes me less confident. So I tried using my Fujifilm X-T4 with a HDMI capture device, since I already had that; a Logitech StreamCam, a Logitech C920 (or C922, not sure), a Razer Kiyo Pro and several cheap 720p webcams. The X-T4 wins in the image quality department (unsurprisingly) hands-down, but you have to run the audio through it as well or use a super low-latency capture device or else the image may lag just a small-but-perceivable bit and make the result feel pretty uncanny-valley-ish. It's a big hassle to set up before every meeting and leaving it on a free-standing tripod is an expensive accident waiting to happen. Would not recommend unless you must have the very best quality you can get (and have compatible microphones and good lights).
I've found the Logitech Streamcam to be pretty solid in terms of image quality. Don't count on Logitech's software if you're on a Mac, because part of the functionality is outright missing or broken, another part is availably only through a virtual webcam the software creates that won't work with most apps, and the whole thing will eat CPU like crazy, I've uninstalled it pretty quickly. Instead I use Webcam Settings [1], which can set the most basic parameters (exposure, focus, pan/tilt/digital zoom, backlight comp, anti-flicker, white balance) directly on the camera, which works a lot better. I digitally zoom it on my head a bit as it's quite wide, and that doesn't seem to hurt the image quality meaningfully as far as Slack/Zoom/Teams calls are concerned (might be different if you stream to Youtube at full res, but I never do). All StreamCams I received mid-2020 had focus issues, but these can be fixed relatively easily by cracking them open and changing the pre-set focus manually (voiding the warranty of course), and they seem to have fixed their QC since anyway, so getting one of these should be a pretty safe bet.
The Razer Kiyo Pro is great as well, with a very nice image, but it's even wider, and last I checked there was no macOS software at all. It still works well on macOS, though, you just can't use anything that requires Razer software, but it's compatible with Webcam Settings, so I'm fine. Using it on the living room TV nowadays for calls with friends and family and it works really well in that function as it's really wide-angle, so I could imagine it would work well for small meeting rooms. It's pretty big (too big for my desk setup, actually) and the microphone isn't great (you definitely need an external one no matter what), but its image quality is really great, considering it's a webcam. Very good low-light performance as well, great colors, looks more like an actual digital camera than a generic webcam.
I didn't like the Logitech C92x I tried at all. Grainy, bad low light performance (not that important as I have lighting, but still), slow to react to lighting changes, ugly, washed-out colors even when lit properly, I sent that one back right away. It was from Amazon so it might have been a fake, and there seem to be several models that are near-identical but differ greatly in image quality, so your mileage may vary.
Next, lights. People are having quite a lot of success with ring lights, but I have my desk against a wall with shelves, so placing a ring lights at the proper distance doesn't work well, and I find they're eyesores. I currently use approx. six meters of Hue-compatible LED strips with warm/light diodes in addition to RGB hidden behind the monitor and shelves, at a press of a Hue switch all come alight and give me a lot of pretty clean, bright indirect light bounced of the wall, and it's essentially invisible unless turned on. Still working on synchronizing the light color and intensity with the outside light coming in through the window, but being Hue-compatible makes that pretty straightforward in theory.
People keep preaching that lights and microphone are the most important things to get right, and I guess it's true. Turning on those LED strips is like a 600% image quality boost even in a relatively well-lit room using a decent camera. If I were to re-do this with a free-standing desk, I'd probably look into using softboxes.
Finally, microphones. Especially when part of a grid of participants in a call, the part of you that gets to make the biggest impact is your voice. It's also a pretty visceral kind of impact; I think there was a piece on that on HN a few months, back, essentially describing how being hard to understand makes people viscerally like you less, so as with lights, nailing this goes a long way. I use an Elgato Wave 3 on a short horizontal arm at around face-height that I can rotate off to the side; since it has a built-in pop filter, it's a pretty compact package and it's fine to have it dangle around at head-height, and since it has a kidney characteristic, I can angle the part with the least sensitivity towards the keyboard to really reduces typing noise by a lot. Before the Wave 3, I used the much less expensive Behringer C1U as well, and while you might want a pop filter with it, it's just fine as well, no gripes with it. Almost any half-decent microphone is going to be a big improvement over webcam microphones, let alone bluetooth headsets, just make sure you decouple it from your desk (there are lots of inexpensive stands and arms that will do this).
If you need to get up and draw things on a whiteboard or the like, I find the Røde Wireless Go and the corresponding lavalier microphone work like a charm, but it picks up mechanical keyboards very well. For my Macbook, I had to add a USB sound interface (a cheap one worked fine) and one of these USB isolator thingies to get rid of a persistent whine when keeping the receiver plugged into USB-C for power. I tried cheaper chinese transmitters that had their max gain so low it was borderline unusable, but I find the Røde Wireless Go (I) to be very solid. Good range and battery life, too.
I'm still working on getting the background right. I can't rely on background removal functionality as I sometimes have to use software that doesn't have this, and there seem to be no standalone solutions that don't hog half the CPU. I've played around with OBS a bit, but it introduces a perceivable delay that I feel makes it a bit harder to take part in fast-paced discussions, so nowadays I try to avoid it. I can't place my desk so my actual background is nice, so I currently use a simple molton fabric backdrop on a rod of bamboo that can be attached magnetically to two little magnets dangling from the ceiling and can be set up and taken down really quickly, rolled up and stashed away out of sight. It works quite well, but it's an opaque white – some structure in there might be nice. As I said, still a work in progress.
Apart from this, I'm quite happy with my current setup, and I've received unsoliticed positive feedback as well, so I seem to have done a thing or two well enough. Not sure if the result is actually worth all the effort I've spent (probably not), but it's been a (more or less) fun rabbit hole/lockdown project.
