This is used a lot in shows and movies, but it has become more important since people have had to quickly pivot and record in less than ideal spaces.įor example, early COVID-19 related lockdowns required that large-scale events be recorded from home and other unusual locations. For example, the producer could use a green screen in the background of the recording setup to seamlessly add a different background of a design or a different location.
#Chroma key live broadcast professional
It’s something to consider when looking to begin building your audience.Chroma keying comes in handy for professional broadcasting.Ĭhroma keying, which is also referred to as “chroma key compositing,” is a cinematic technique that is used to blend two different media files together by picking up on color hues. There’s no right or wrong, plenty of streamers have had success both with and without green screens. The posters on your wall and the trinkets that you display on your shelves give you character and can even help streamers build a relationship with you more than a green screen ever can. Some of the most popular streamers around right now like Summit1g and TimTheTatman use their background as a way to visually express their interests to their viewers…Okay, and sure, also for some paid promotion, but that’s never hurt anybody. It also may be time to think about upgrading.Īnd lastly, a question for you to think on: Is a green screen truly what you want to use on your stream? I don’t mean to say it’s not a great thing to have, but for many streamers, their natural background becomes part of their presentation. Drops in framerate can be a stream-killer, so if using a green screen is putting your CPU into a lurch, then it may be wise to use your webcam without a green screen for the time being.
Implementing a green screen in OBS and SLOBS is very intensive on a CPU and can lead to dropped frames.If you’re using a webcam that uses Auto White Balance (AWB), I would suggest disabling that feature, as it can change the color of your green screen as it tries to balance out and cause problems through this whole process.If you’ve found a video online that features a green screen in the background, you’ll be able to apply the chroma key to that video and have only the talent of the video play on your stream. The ability to apply a chroma key within OBS and SLOBS isn’t just limited to webcams.As we’ve learned, OBS and SLOBS are set up to remove that color from the presentation, meaning you could be a floating head on stream if you’re wearing that same color. Always avoid wearing the color of your green screen or having it anywhere on your body whatsoever.Here are a few things to know and to think about before you head back out to the streaming sea. I hope you’ve got a big smile on your face right now because you should see only your talent laid against a background of your content and nothing else! Move your hands around to see what distance you have to work with and then prepare to show your stream the NEW YOU. Hitting Close will allow you to take in your newly created Chroma Key filter. The other options should be familiar to most streamers, but they really don’t need changing all that much.Know that a little green in the hair isn’t going to ruin your stream. If you’re noticing some green bouncing off the edges of your shirt or your head, move this slider to remove them. Spill Reduction applies to the edges of what the filter is and isn’t removing from the screen.Use it to hone in on the perfect amount of what’s left on the screen. You shouldn’t have to move this to a large degree. Smoothness works in tandem with Similarity in trying to make sure that the filter isn’t too harsh.Make sure not to increase this so much that some of your talent is being removed too. Adjusting this slider will allow OBS to grab more of the screen. This could be because those corners aren’t as well lit as the middle of the screen and OBS isn’t recognizing that it too needs to remove the corners. For example, in the darker corners of your preview, you may see that OBS isn’t removing some of the screen. Similarity is how close to the base color you want OBS to also remove.If you have anything besides an actual green colored screen, use this drop down to find the right base color.
