Instead of stretching the window, there's a crop filter just like the chroma key one, so you can crop out all the corners you don't want :) Very clever idea!
Brilliant tip! Building ideas with your audience instead of presenting finished concepts (ppt slides) is the best way to maintain audience engagement. It also improves note taking outcomes for those on the receiving end! Now we can do it magnificently with Surface! Thank you Scott and Rob for taking the time to share!
Being subbed to you is a gold mine of skill learning. Thank you Scott. Chroma-key on a PowerShell terminal is a decent use this tutorial made apparent.
Instead of removing the green with a chroma key you could remove the white or black background with a luma key... this way it wouldn't affect colors :)
A luma key? I will have to Google that. I am trying to do a similar thing with a PowerPoint presentation. I want some of it to be seen But the main back ground to be transparent

Just started to use OBS for teaching, this tip is absolute great
Did you see any tutorial for using OBS for teaching? I would love to include it on my classes!
3 года назад+1
@@Pameliux23 I saw some videos about how to use obs, not precisely one about how to teach. Mainly, I use obs to record my class, for example this ruclips.net/video/a6sd-X2OtXY/видео.html (sorry is in Spanish) but that's the idea
Very smart, and here's a pro tip : chroma key works by using contrasting subject and background colours. It is typically green since that is tthe opposite of human skin tones. In this case, using a black background and a white pen might look best. It also allows you to change blending mode instead of keying, therefore get cleaner outline with less processing power :)
Scott, you inspire me to be a better communicator/developer. Your videos are great and concise. This gives you more bullets to your arsenal and now mine! Thanks
Thanks for sharing this! Would love to do the lightboard but that's a static and serious investment so this helped a lot. You can do the same in OneNote (more green options) and as far as training goes, OneNote with presentations converted to PDF and then imported makes for a nice virtual training environment. Would be nice if WhiteBoard and OneNote had full custom color background options in future (you can dial it out with OBS I suppose). You can then also use the Virtual Camera addon for OBS to pipe this into Teams for example (so you have a virtual webcam and can then go between presenting your desktop sans webcam or webcam and this trick).
Scott, THANK YOU for this. Perfect demonsatration. I've been trying to work this out for hours; trawled so many videos. Just couldn't get how to superimpose over the top of the background.
Great video, thank you very much!.. If Microsoft Whiteboard introduced a "glass" (transparent) background, that would really simplify things, wouldn't it?
Keep you and get rid of the background, fab video, saw this last night at lightboard.info but it was many, many thousands for special glass etc. Great video. Brings it to the masses.
@shanselman love this! I tried and works great BUT there’s so much you can write on the surface screen. Do you have any tips on making yourself a bit smaller and giving more space for the screen content? I found myself limited by the MS surface screen size
LOL you just exposed my video secrets . I use Bandicam for writing directly on the video without having to extract the color and use my live camera capture.
Neat! I might try and have the presenter be “faded” in the background. Basically let the chroma key not be 100%. This should help the text be easier to see when writing over the speaker’s face, and the speaker be visible, but more so in the background. (Then maybe create another “scene” that I can toggle when I want the speaker to be more prominent.)
This is great, I have no experience with these methods. Is it possible to turn the background black like the light board videos so the pen is more visible?
Any idea of how to add virtual pencil📝 to looks like your drive you back of you screen? PS: the pencil may appear(zoom in) when you actually touch the screen.
Please, could you tell me how can I make the background blurred using this technique? When I talk about background I telling all things behind the virtual board, including you. Thanks in advance.
Well, actually there's an OBS script that allows you to do screen boarding without needing any other apps, called OBS Whiteboard Source. I had tried this scripts and it runs inside OBS by using windowed projector. The only drawback using this script are the feature which is may not be as good as using an external applications, but I think it was decent enough to do the work. Here's the source: obsproject.com/forum/resources/whiteboard-source-windows-only.919/
Quick question: Is this two participants in the same web conf (one your main PC, one the Surface)? Or are you using OBS for multiple inputs on the same web conference? If it's the latter, how do you get the surface and the main PC to work together in OBS? TIA.
It's cool that it's possible but I'm not quite sure of the use case of making it harder to read by being overlaid on top of your entire background vs just showing the screen itself
Hi, I was just wondering if you were using the Surface connected to another monitor as your main computer or if your were casting from the surface to another computer for this! Great video, thanks!
Instead of using screen capture use window capture instead and that will capture just the window of any program you select rather than the whole screen
Awesome video, you deserve more than 100k followers, i suggest doing more technical videos about frameworks, Software design, and best practices topics. if you haven't enough time to prepare rich content on these topics, you can invite people to your show.
Great video and explanation, been looking for something like this! Question when you were writing can you see your OBS screen on whatever you writing on? Would be good if you can just have an initial reference point and then when you write on the screen it will become easier and natural.
This is really cool! A question, since you mentioned you're using a Surface. I had been using OBS while teaching over Zoom, mostly with OneNote for presentation. I gave up because my Surface Pro 7 couldn't handle running Zoom, OBS, and OneNote at the same time! Have you been able to make it work? I've got the version with a Core i5 and 8 GB RAM because that's the best I can get on the budget my institution allows. I've been wondering if I just got a dud unit.
OBS has a built in 'virtual camera' that Zoom sees as a source. It works on the Mac. The issue with using OBS as a virtual cam in Zoom (besides performance with lots of sources/filters on older machines) is that Zoom sends out standard definition for video, unless you jump through a lot of hoops with them. So any fancy setups with screen/window captures of small text and details (demo-ing software for example) might be blurry for participants. Zoom Screen sharing uses a higher res (but a slower frame rate).
For a work setup, using Teams or Zoom, can you demo a 2 device setup? i.e.: Work laptop running Teams, screen share (showing VS, VSCode, SQL, etc) and an external Surface device (I have a Surface Book 2) in detached mode so it can be used as the clear whiteboard? Circle this section of code, point to inspector error detail, etc... Will OBS work with Teams/Zoom?
Yes I would do that with NDI Tools. So run NDI Scan Converter from ndi.tv/tools/ on the Surface, then use an NDI Source on the OBS machine to pull in the surface's screen!
Yes, I know of one way using third-party software. You can use XSplit Vcam with OBS. The free version has a watermark, so you would have to purchase the pro version to remove it unfortunately.
I strongly feel this should be a standard feature on Microsoft Whiteboard / Teams. I would feel overwhelmed if I had to manage Teams, Whiteboard, OBS (AND sometimes, Powerpoint) simultaneously while busy with a meeting or presentation. Cool hack (sincerely), but probably something that would not work for me.
Yes/no/not really/kind of. If you use window capture to capture their screen and feed it into OBS, you can annotate it this way and then send it back out as *your webcam*. This only works if you're using the gallery view so that their screen doesn't keep disappearing or moving while you're talking.
This is my pain point. Every video showing OBS for teams and setting up scenes never seems to go to the last step. When you are in a call with other people, your camera is now a small box and unreadable with all the other cameras. Which feature do you use so that Teams displays your full Virtual Camera screen full screen without auto zooming and face tracking. I tried “focus” on me so I was the primary but it would still zoom in or move around the image is I lean to the side.
This is so cool! I'm new to OBS, I'm using it on my next video. I could do this for double screens (no camera) right? to add notes on to a screen while explaining things Thanks for sharing this!
But my camera and my whiteboard application have to run on the same box, right? There's no way I can connect my tablet for whiteboarding to my 'broadcast' computer?
Hi have a look at NDI tools. you can broadcast over a network (has to be wired), they have screen capture tools and input drivers on the device where you broadcast from
You can crop screens with ALT and the box points. Easier than to stretch a screen outside the box.
Thanks!
You mean use alt in OBS to crop an element?
Instead of stretching the window, there's a crop filter just like the chroma key one, so you can crop out all the corners you don't want :)
Very clever idea!
Or you can crop the source by pressing Alt+dragging the borders
Brilliant tip! Building ideas with your audience instead of presenting finished concepts (ppt slides) is the best way to maintain audience engagement. It also improves note taking outcomes for those on the receiving end! Now we can do it magnificently with Surface! Thank you Scott and Rob for taking the time to share!
And if you want to get crazy... Share the whiteboard live with the audience and see what happens! 🤣😂🤣
Being subbed to you is a gold mine of skill learning. Thank you Scott. Chroma-key on a PowerShell terminal is a decent use this tutorial made apparent.
Every once in a while you see something in tech that makes you smile. This is one of those. I can't wait to do this next week. Thanks Scott.
You're the best kind of teacher 😄
Well explained, creative and showing other people's work and ideas 👍

Nice! You can also crop it by holding Alt+dragging the corners/Side you want to crop.
Hope Our professors are able to do that
Signs of a good developer, force yourself with every grain of power to use something off the shelf instead of coding it 🤣
But its soooo hard to do 😣

I like this. And the idea of punching a hole through other windows and graphics.
Thanks for sharing this trick, very much appreciated m thanks to you I'm now using OBS pretty regularly

You, sir gave me exactly what I was looking for for about 3 hours now. THANK YOU 👌👏🙏 you've got yourself a new sub from France :)
I was wondering for a week how to write on glass. Interesting and this video came. Awesome..
Thanks Scott, this is incredibly cool and something that I can definitely use with my Family Office clients!
Great video, thank you very much!.. If Microsoft Whiteboard introduced a "glass" (transparent) background, that would really simplify things, wouldn't it?
Really cool and simple way! Nice demonstration! Thank you
This is my new favorite channel. Subscribed, Liked and saved video for reference later.
This is coooool! thank for sharing this. It never occurred to me that this could be done :-)
Nice video - you can also crop an overlay with the alt key
Thank you for sharing, Scott - much appreciated!
Keep you and get rid of the background, fab video, saw this last night at lightboard.info but it was many, many thousands for special glass etc. Great video. Brings it to the masses.
That is a freaking cool idea. Thanks for point it out Scott.
The highlighters work better because they premultiply the background, which makes for better anti-aliasing
Hey Scott! Your videos are very useful, thanks for sharing 😀

Must try to use a remarkable 2 with live view. If thats work it would be great.
do you have a similar tutorial with iPad for example ?

Thanks for sharing, nice video. I'll try it
Just one word Thanks
Very nice liked it
This is All I wanted. Thankyou :)
Really cool!! 😍
is that a external camera connected to a surface or is the surface connected to a pc? can we know your setup?
This is awesome. Thanks for sharing

Very good idea,
AFAIK zoom does not accept obs output stream as a Webcam source especially on macos. Am I wrong?
OBS has a built in 'virtual camera' that Zoom sees as a source. It works on the Mac.

Zoom Screen sharing uses a higher res (but a slower frame rate).
Can this be done with only one screen or you need 2 screens?
Thank you for making a quality video
This is awesome! Thanks Scott!
Ingenious! Unfortunately, I don't have a surface. Any idea how to make use of this on a non-touch laptop?
You could buy a cheap drawing tablet, that's probably the best substitute.
@@lansraad6142 That's a great idea. Thank you.
@@ExtremeWays4Bourne Yes, and you can also draw on the screen with your mouse

Thanks for the tip Scott 👍
Superbbbb Scott 👌
Does work on laptop or do you require a surface?
Thats great. But, can a person with only one monitor do this?
Cool video !!! 👍👍👍👍👍👍
Hi is it work on Macbook with ipad as 2nd screen? thx
Any chance to have a background remover without owning a green screen? The same that we have with MS Teams?
Yes, I know of one way using third-party software. You can use XSplit Vcam with OBS. The free version has a watermark, so you would have to purchase the pro version to remove it unfortunately.
Alter you showed it, it is so obvious to do that 😁. Thanks for sharing!
I felt the same way! 😍
What device are you writing on? Surface tablet or directly to a touch screen monitor?
Was a surface laptop with touchscreen
So. Freakin. Cool!! Thanks for sharing!! 😍
I strongly feel this should be a standard feature on Microsoft Whiteboard / Teams. I would feel overwhelmed if I had to manage Teams, Whiteboard, OBS (AND sometimes, Powerpoint) simultaneously while busy with a meeting or presentation.

does this allow you to draw on someone else's screen in Teams like how you can annotate on zoom?

There was talk of introducing NDi into teams. It’s already in Skype and used by broadcasters
There is an ndi plugin for OBS now. So you just need the OBS input on the broadcast device.
Great Scott, thank you.
I did the same thing except with microsoft paint.
