With my webcam cropped how I’d like it, I can move it to anywhere in my scene. Let’s actually close the filters panel and take a look at what happened in the final result. So, after I get the left side cropped out as desired, I can just type in what I want for the top. We can also simply manually type in an amount, which is in pixels, to remove certain areas as well. So, if we start with left, we’ll notice that the left side is being removed from our source. We can use the arrows on the right to slowly adjust the amount to crop by simply clicking and holding. Let’s pretend that our webcam has a bit too much showing on the left side and top. Add it just like we did for the Image Mask/Blend filter, and we’ll see a familiar set up. Let’s move on to an easier to understand filter, crop. You can remove filters by selecting it and hitting the minus button. If not, don’t worry too much – as this is something that isn’t extremely important. If you’re familiar with Photoshop layer blends, this achieves the same effects as that. You can also use filters as blends, meaning you can take advantage of multiply, addition, and subtraction blends. Also, if I checkmark stretch image, you’ll see that the circle is stretched, so that the mask image I selected fits the entire source.
Grays will actually cause transparencies. The easiest way I remember how masks work, is that black hides and white reveals. If I select this image as my path file, and select Alpha Mask (Color Channel) you’ll see that my webcam will now have where the black areas are hidden. You’ll notice that around the edges the image is black, and in the middle is a white circle. To do this, let’s use a black and white image as an example. You can use a mask to hide certain areas of your webcam. Okay, so what does this mean? Let’s say you want to put your webcam in a circle shape. Stretch image (discard aspect ratio) will actually take your image that you selected to use as a mask or blend, and fit it to the entire source. Opacity can go from 0 to 100, where if you lower it from it’s default of 100, it will become more and more see through. Color you’ll generally want to leave on its default. Path will give you the ability to select a specific file to add as a mask or blend. You will first be able to select what type of mask or blend you would like to use. Image Mask/Blend might seem complicated as a new streamer, but let’s take it slow and hopefully you’ll understand what uses you can have with it. You’ll see that filters have the ability to be toggled on and off, just like sources as well. For Image Mask/Blend we just select it, name the filter, and hit okay. We’re going to notice that adding filters is pretty similar to adding new sources into OBS. Now, we can hit the plus, to add a filter. We can see our current selected source on the right. But again, let’s look at the Effects Filters on the bottom-left. If our source allows Audio/Video Filters, there will be a section for them at the top-left. To use a filter, let’s first click the source we want to apply it to, right click, and select Filters. We’re going to start by going through each effect filter first. Another thing I’d like to quickly mention is that there are two types of filters: Audio/Video Filters and Effects Filters. We’ll touch more on this in a future video, about setting up our scenes. This means that if you want to have different filters applied to the same source, you’d have to add that type of source in again, and then name it something different, such as image 2. However, if you apply filters to a source in one scene, they will carry over to any other scenes that your sources are used in. I am not in this business for commercial reason, but just from personal interest, I would be happy to sponsor work here with some small amount of money.The thing you need to realize about filters, is that they can be added to every source individually. I think demand for something like a Nvidia GPU is totally acceptable for something like this as well. Person B's head -> Plugin C could use it to "fuzz it out" for anonymization Person A's head -> Plugin B could use it to attach a text object showing brand of t-shirt So anything in the feed would be tagged in a way that other plugins could use. I think what would be very cool would be to get a general object classification system into obs.

This is a great start, but a bit unstable and unpredictable.
