Hey everyone, it’s Derek with Nerd or Die. And In this video I’m going to show you how to use filters to modify your sources inside of OBS Studio. This will allow you to do things like cropping, green screen effects, and even delay different sources.
The thing you need to realize about filters, is that they can be added to every source individually. 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. 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. We’ll touch more on this in a future video, about setting up our scenes. Another thing I’d like to quickly mention is that there are two types of filters: Audio/Video Filters and Effects Filters. We’re going to start by going through each effect filter first.
Let’s move on to an easier to understand filter, crop. Add it just like we did for the Image Mask/Blend filter, and we’ll see a familiar set up. Leave Relative check marked. Let’s pretend that our webcam has a bit too much showing on the left side and top. We can use the arrows on the right to slowly adjust the amount to crop by simply clicking and holding.
The scroll filter can actually be used in some interesting ways. First, it’s very useful to make text sources move from left to right, if they’re too long. Next, let’s say you have a repeatable pattern, or maybe a static image that you’d like to see move a bit, you can use scroll to make it move horizontally or vertically. To do so, just adjust the sliders with the speed of each direction you’d like to have it move. OBS will automatically make the source sort of repeat itself.
Let’s go ahead and move on to our next filter, the Color Key, but let’s actually talk about Chroma key as well. So, you might have tried each of these out yourself, and you may be wondering “what’s the difference”? Well, I’m going to make it quite simple for you. If you want to filter out or hide a green screen, use the Chroma Key. From what I’ve read and seen before, Chroma key is what more streamers will want to use. A color key can be useful with graphics with a specific color you’d like removed.
Anyways, I’m going to actually add in an image as an example of a green screen, and show you what the settings do inside of these filters. Let’s work with the chroma key. We can work from the preset colors under Key Color Type, or we can pick a color of our own. Fro green screens, this is generally the best idea, to select the closest color to your screen possible. So, with Custom Color selected, let’s hit select color. Here, we can select colors in various ways, or we can actually use “Pick Screen Color” to pull up a sort of eye dropper that will match the color we’re hovering over. Go to your source and select the most common color shade you see in it, that you’d like to key out. Simply click it and you’ll have the color you need. You can hit Add to custom colors, to save this color selection, and then Okay. If you’re using a green screen, you might already see some good results, if not, don’t worry, we can do some tweaking to the options.
First, if you plan on using a green screen, I can’t recommend anything better than properly lighting it. Having a more consistent color of green screen will produce the best results. Ideally the entire screen is the exact same color/shade. But, in reality this isn’t possible. So, let’s talk about what each option does.
