Not only does a stream look more professional with a green screen, but it helps the audience see more of the game, or immerse them further in the action. The most significant selling point on a green screen is how smooth it makes everything in a stream look. Then, set the color as a chroma key in OBS. (Looping is optional.) You can jump to any frame in your movie by dragging or typing in the Jump to Frame number box. OBS is free established software for video recording and live streaming. You can also hit the spacebar anytime to play your video clip from the beginning. And if you're going to be a big focus on the screen in a broadcast, then a green screen is the best way to make the background go away. Like editing software, Chroma Key Live uses the J,K and L keys for backwards, pause, and forwards. Plenty of people stream without the use of one and do just fine, but the addition of a green screen is a good way of upgrading your streaming experience without doing too much. Using a green screen isn't exactly necessary to stream, but it certainly couldn't hurt. Start by adding a new layer to any graphics overlay channel. Many video editing software such as Adobe Premiere Pro, Final Cut Pro, HitFilm Express, and Apple iMovie allow you to work with green screen for Chroma Key. Chroma key is done through the graphics module. When it comes to pricing options, many of the more expensive choices out there simply offer more convenient ways of displaying or setting up a green screen. Livestream Studio includes chroma key, giving users the ability to remove a color from the video source, typically a background color to replace with an image such as a virtual set. Thankfully, the differences in many screens are minimal, with many only offering either anti-gloss features or more of a "standard" screen. Do you need a green screen?Īs you begin researching various green screens, it may be a bit alarming to see there are so many options out there. Today though, you can use green screen software for live streaming and replace your background in seconds. In the past, it was primarily used during the post-production or editing process. But if you're just looking to have a good looking stream and save some cash, they're well worth a look. Chroma keying works by 'keying out' or digitally removing a solid color (usually green) background from behind a person or an object. It can also use either GPU or CPU encoding, so if you have a monstrous CPU with resources to spare you'll be able to tap into that.īoth of these aren't quite as good as a proper green screen, and if you're looking to do professional broadcast work then neither is a true replacement. One of the most popular is XSplit VCam which is free to download but does have a paid element to get the most from it.įeature-wise it's very similar to NVIDIA Broadcast, offering a choice of background tools including blur, removal and replacement. If you don't use an NVIDIA GPU there are options out there, still. If you want to cut just a couple of cameras and overlay titles, then the mx10 and 12 are pretty good bets if you can find one.Source: XSplit (Image credit: Source: XSplit) How to apply Chroma key visual effect Choose a background image from your gallery or take a new one. Most edit software has keying built in, although off-line software dedicated to this kind of this worls better, especially vector keying which is kind of like chromakey, but lets you have shadows, and key through things like glasses of water, which are really problematic normally. DV colour compression means that green as a key colour is better than blue. Panasonic mixers, and others have reasonably decent chroma and luma keys on the 50/70 ranges, but the old MX10 that often pops up on ebay could do pretty good simple luma keys for graphics, titles, mono logos etc.Ĭhromakey from live sources, even composite isn't normally a problem - as long as the lighting on the background is even. software that can do chroma keying on the fly AND record the result or the live feed (in that case we add the graphics in post production) - and a capture card/device that will take hdmi (from the NEX-VG10) and show as a capturable device in the chroma key program in Windows 7. You can use chroma key - and either select the key colour as your background graphic colour or change the graphic background layer to a suitable key colour. This light will help to separate you from the green screen and add depth to the shot. Position the back light behind you, pointing towards the green screen. For chroma blue, it should read at about 25-30 IRE. For chroma green, the line should be at about 40-45 IRE on the waveform. The line should rest at the proper level of brightness. This light should be dimmer and will help to fill in any shadows on the your face and body. A good, well-lit background should show a straight, tight, horizontal band on the waveform. You don't chroma graphics normally, just a simple luma key does the trick. Position the fill light on the opposite side of the key light.
