Prior to the discussion based on the segregation of the best chroma key software available in the market which would assist live streaming, let us analyze closely what a chroma key is. Chroma key is a video conglomerating procedure backed by video broadcaster software. Grafting two live video streams into a sole portrait array is the principal job of this key. Interweaving two streams which are running abreast to each other can be blended into one image sequence. Also referred as color-separating overlay by BBC, this approach is one of its kinds which is dictating and will continue doing so in the world of live video broadcasting.
This combining scheme of the chroma key is basically used to locate a dynamic object adjacent to the backdrop which is totally a made up one and the object is not present at the location which appears in the scrim. Fundamentally speaking, two images of the commodity and the scenery are being merged together to create a single frame. This phenomenon can be carried out post the endeavors with the camera and also in the middle of the stream. A green screen is set up behind the object in front of the camera, for example a person might have a different background when the broadcast is appearing in front of spectators. Certain visual effects and making the imagery impeccable are being popularized. Chroma keying can be carried out with backdrop of any hue which is consistent and apparent. However, it is advisable to use colors such as blue or green since the human skin tone is nowhere close to these two pigments. Used in weather forecasts broadcasted on news channels, movies and video games the technique of chroma keying is applicable in day to day life in this era.
Let us now discuss the chroma key software used for live streaming:
Above we have already had a detailed discussion as to what exactly is a chroma key. Since discussions about how to implement a green screen or a blue are over, thus we must advance on to the software which is being used to encode such an enthralling imagery. The back office of the chroma key implementation is exceptional and must be acknowledge without commotion. Before the advent of computers and contemporary technology even the thought of such a feature was impassable. However, with the commencement of automation, dreams turned into realty. Chroma key software abundant in the marketplace redefines the visions of broadcasters and film makers.
Let encoding software be the focal point here. Live streaming is completely dependent upon the chroma key as the key is directly subordinated by broadcaster software. Here we will also spotlight the points where the major functionality of a chroma key can be discussed. In the beginning, this procedure was matured for videos that have been preserved. The beginning takes us to the age where digital way of like was unthinkable and analog machinery was in use. Live broadcast software these days grants you the permission to use chroma key and live broadcasting spontaneously.
Adobe being the harbinger of visual effects studio work has introduced “Adobe Flash Media Encoder” as the most widely used and primary software for encoding the live stream. Unluckily, this video broadcaster software lacks the aspect of the chroma key and live stream running side by side and is subsequently disregarded for further use. This complimentary software was last refurbished in the year 2009. But this feature is abundant in some of the other recognized encoding software such as:
WIRECAST
In Wirecast, chroma key compositing is carried out inside the shot redactor setting. This operation can be executed in the middle of a live broadcast even when the broadcast is on air.
Right clicking on the point of supply of the camera would open a list which lets you select “Edit Shot” from the menu.
Down below flashes an icon with that of the photo of a person. From the editor list, click on this very icon which is also the chroma key features button.
A submenu pops up and leaves you with a critical choice of whether to add a static image or a live video broadcast as a reinstatement for the “chroma key screen”.
Select the “use chrome key” button and get ready to pursue the project.
With the vision of making things more appealing, in essence arrangements and a set of pragmatic templates allow you to assimilate your backdrop theme into a calculated setup for general broadcasting aspirations. These patterns add a convenient forefront in certain cases, which makes the person look as if he is standing or seated behind a counter or a platform. Every template has numerous amounts of layers which complicates the elementary chroma key operation. Click on the “Go” button once you are ready to initiate the broadcast.
OBS
OBS or Open Broadcaster Software has limited resources to offer. Premeditated designed buzzers and blares are scanty but every complicated is curtained with this encoder software.
Navigating to camera properties will be a priority since it is the site which contains your screen content.
The “Use Chroma Key” box can only be empowered by clicking on it since the default settings keep it in a semi-paralyzed state.
The color case; once clicked upon brings forth a list or a palette like menu from which the background color can be verified and put to effect.
Set the “Similarity”, “blend” and the “Spill reduction” within a range of 1-1000. Ideally, this segregation defines the spectrum of colors from the lot.
Setting the similarity at an insurmountable range such as 800 is well-considered by some users, whereas it has been factually stated that if the person behind the camera is well equipped and the photographer is adept, a similarity of 100 will be more than splendid. Experts even advocate halting the use of “eye dropper” procedure in vMix. As soon as the chroma key kicks off, the backdrop must be set up and be previewed as to how it would look in real life.
vMix
Having discussed one feature of “eye dropper” you are certainly wondering as to what exactly is vMix. vMix needs bequeathing and fidgeting but is as simple as Wirecast when being implemented. The chroma key software here introduces some steps which have to be abided by:
Below the primary façade you can witness a small windows screen. Clicking on the “Add Input” button for the window on the left side which will help you summate your stream on the forefront.
This also must incorporate the green screen. Double clicking on the portrait opens a pop of menu from where you need to select “Color Key”. Tapping on the “eye-dropper” image helps you select the accurate color.
“Auto Chroma Key” is also available in case someone requires a black backdrop in place of the previously set scrim.
To increase exquisiteness of a content calibration options are available.
Clicking on the “Add Input” button once again allows you to add a backdrop of your choice or even choose one from the preinstalled imagery on vMix.
The “Set-up” button must be clicked once background framing is complete to initiate layer selection process in a stream. The “talent” layer provides you with different camera angles and effects which would spruce up your content.
Xsplit
This chroma key software was designed keeping online game broadcasting in mind. Chroma key commodities suit this encoder well since the keying is crucial here.
Layers are relevant to set up so that the forefront broadcaster has a superior layer than the background simulcast. The lower left portion of the screen with the source illumination initiates this process.
A right-click on the stream which is in front and not the background brings forth a menu, which has the “Color” tab waiting to be clicked upon.
Clicking the radio knob mobilizes the chroma key.
A submenu aids in the segregation of key color, “threshold” and other aspects.
VidBlaster
Here, the chroma key is being controlled by the addition of a development system. Capturing, recording and streaming sports events are at the tip of your hands.
The “Module” menu must be clicked upon initiation, followed by the selection of “Add” and then the “Effect” option must be put into use.
A module case is opened which contains drop downs with lists to choose from.
“Chroma Key” must be selected from the topmost part of the list.
The menu case to the left picks the forefront source while the one to the right selects the backdrop source.
Updates versions of VidBlaster with foolproof video broadcaster software has also incorporated an “Advanced Settings” option for the betterment of the application.
Again, the points discussed above pertaining to the best chroma key software for live streaming is subjective. There lies other chroma key software which might capture your attention. Easy to arrange and organize, this is dependent on a lot of other factors such as the aspects and traits of the photographer and the equipments being assimilated in such a venture.
Setting up a live stream is a straightforward affair, as long as you have all your elements in place. With technologies such as StreamNow making the rounds in tech circles, live streaming is proving to be more affordable and relevant for companies across the board. That said, it can often be daunting for a novice to procure the necessary live streaming equipment, technology and content to set up a streaming platform. If you just felt a twinge of recognition, this guide is for you. Here, we walk you through the video broadcasting equipment you’ll need to establish your very own live streaming service.
Live Video Streaming Equipment
1. Camera:
You already knew this, but what you may not know is that you needn’t invest in obscenely expensive live streaming camera equipment to set up a streaming platform. You can use your smartphone or a budget webcam just as well. Of course, if you are inclined towards rendering your stream professionally, an HD camera is your best bet. There are hundreds of models that you can choose from, and if you’re especially strapped for cash, it’s worthwhile to wait for a sale to clinch a great price.
2. Microphone:
If you’re tempted to settle for a cheap microphone, think again. A good quality microphone can take your stream from good to fabulous, lending a certain continuity and voice to your delivery. Granted, your camera most likely comes with a microphone inbuilt, but go for an external microphone if you’re seeking superior voice quality. This way, you can cut out the noise and channel sound effectively. Again, there are a host of microphones available in the market and waiting to catch a discounted price is a good idea. If you’d rather pick now, Micro Boya BY-M1 and Micro Audio-Technica AT2020 are favorable options.
3. Encoder:
An encoder forms the confluence of your audio and your video, meshing your sound and your images together. There are two types of encoders you could consider.
Physical Encoders:
A physical encoder is a cuboidal device that contains jacks for your camera and your microphone. It can be connected to the web, allowing for a stream to be transmitted in real time. Here, it is important to note that a wired connection between an encoder and a device works best; alternatives like Bluetooth and Wi-Fi can create lags, as can a shared internet link. If you’re conflicted about which encoder may work best for you, look at models by Vbrick, Tricaster or Matrox.
Encoding Softwares:
If you’d rather avoid the hassle of purchasing a physical encoder and would prefer to take a less expensive, yet just as effective route, an encoding software is your answer. While some come free, the more sophisticated ones come with a price tag. The catch here, though, is that a streaming software is intrinsically tethered to your computer, and you must carry your computer with you wherever you go in order to stream. Your microphone and camera, too, must be connected to your computer. Keep in mind that an encoding software requires a resilient, powerful computer, so if you have a limited RAM or have a computer with a low processor, this option may not be for you. Some good options as far as encoding software’s go, are Adobe Flash, Xsplit and Open Broadcaster.
4. Internet Link:
Without a strong internet connection, you may as well kiss farewell to your live streaming service. Make sure you pick an internet connection adequate enough to support content in HD or 4K. An upload speed of 2.5 Mbps is a good starting point, and to make sure that your bandwidth remains consistent, protect your internet link from others. To know your bandwidth speed, take a speed test online on speedtest.net. Another point to consider is getting a rock-solid wired connection. A wired internet link is far more sturdy than a wireless one and will offer you a lower latency in comparison. If your streams are captured on the move, then a wireless connection may be your only option, but even here, make sure that you don’t share access with other users to maintain optimal internet speeds.
5. Live Streaming Software:
Typically, setting up a live streaming service would entail dozens of man hours of coding, designing and developing, in addition to various other resources. Luckily, the advent of turnkey frameworks has made setting up a live stream easier for businesses. StreamNow, a product developed by parent company StreamHash, is a welcome innovation for tech entrepreneurs. The framework fits easily into a company’s existing technology stack, offering it a real-time interface with customers.
When it comes to live streaming, it is important that you build your infrastructural ecosystem to be robust, especially if you plan to broadcast streams on the go. As you set sail on your new broadcasting adventure, make sure that you have all the right equipment for live streaming. This way, the winds will always be in your favor.
The most hackneyed and clichéd question that people often ask me is- What is the best webcam for streaming? It doesn’t take long enough for me to reply with an essential banality- There are no easy answers. Truth is that cameras are equipped with cutting edge technology. But that’s not the big story. The big story is that they vary in price, quality, specifications and other details. The apocryphal stories of people making certain live streaming camera commitments have little truth. Selection of the right camera is just a procession. The following questions should be answered with alacrity:
What is my budget?
Do I want to stream only live?
Can the camera get along with my laptop/desktop hardware?
What are the flexibility options to be considered?
Answer all the questions mentioned above. Let us now discuss the types of cameras for live streaming:
Webcams
IP Cameras
Professional Quality cameras
Webcams for Streaming:
The word ‘Webcam’ stands for a web camera. Webcams are digital cameras capable of sending live pictures from one location (where it is connected) to another location via internet. Latest desktops and laptops are configured with a built-in camera. Certain desktops do not have a built-in camera. Some webcams can be connected to the computer via USB or via Wi-Fi. Be informed that webcams do not have their own internet addresses. For all intents and purposes, a laptop/desktop computer is mandatory to connect to a network. In the absence of a computer, webcams cannot process images.
Advantages are manifold. Simplicity is too strong an advantage to be not quoted. Ease of use is yet another plus point. You do not require any dedicated capture cards to control the functionality of webcams. Also, external power sources are not required. Webcams are affordable. For 100$, a good quality webcam can be obtained. As far as software is concerned, no additional software is required for the smooth functioning of webcams. It is assumed that you have all the software required to stream video content.
People often ask me this question- Can webcams generate high-quality images? No, they do not generate high-quality images. Moreover, they do not have any dedicated storage space to store images. Hence, they cannot be used as separate entities. They have to be used in liaison with computers.
Most of the webcams come with built-in microphones. However, the sound quality may not be professional. If you are looking for professional sound quality, a separate mic and sound channel are necessary. Webcams do not have sophisticated controls. As a result, features such as variable focus and zoom capability are absent. Another important feature that enables users to customize images is also absent. Well, the importance of such features depends on the purpose of the webcam. If you are looking to address a conference or deliver a lecture, a webcam with normal specifications should suffice. If you are looking for professional quality video and audio, do consider other options as well.
Before delving into further details, here is a quick rundown on what other features a typical webcam possesses:
Sensors: Sensors are capable of detecting movements. The moment they detect any movement, they will start recording.
Microphone: Microphone is an electrical equipment which is capable of converting sound into electrical signals.
Light: Light lets you know if the camera is in use or not.
IP Cameras for live Streaming:
As the name suggests, an IP camera has an IP address associated with it. This clearly implies that IP cameras have the ability to connect to the internet. They are independent of computers. Advantages are many. Versatility is not hyperbole. Thanks to POE (Power over Ethernet) capacity, it is easy to run IP cameras for 24 hours round-the-clock. If you are looking for live video streaming, IP cameras are ideal.
IP cameras are costlier than webcams. A good IP camera can cost you around $800 or more. Prices vary. IP cameras have sophisticated and advanced specifications. The protocols that these cameras use are not suitable for live streaming. Hence, you require an encoder to facilitate IP camera live streaming. Video encoders convert videos in one format to another format. IP cameras offer better flexibility. Their location is relative to the location of computers. In many aspects, IP cameras are better than webcams.
Professional Quality Cameras:
Both HDMI and SDI cameras are capable of pulling off miraculous live video streams. HDMI and SDI cameras are costlier than IP cameras. And yes, a separate capture card is required to set the live streaming tone. Capture cards are nothing but devices which are capable of converting video signals into usable formats. Capture cards are of two types-
Internal capture cards
External capture cards
Internal capture cards offer advanced functions and are cheaper than external capture cards. External capture cards are plug-and-play devices. Not all capture cards can work with analog video signals. Some capture cards work with digital video signals. Some cards are designed to work with both analog and digital video signals. Before making any purchases, it is important to check the particulars and specifications of the card. Professional SDI camera is the best camera for live streaming.
In professional HDMI and SDI cameras, you can expect utmost flexibility. Apart from changing and upgrading the lenses, you can do a lot of things such as widening the focus angle, you can change zoom and produce polished productions. Portability is good but not as great as IP cameras or webcams. HDMI and SDI cameras are heavier than IP and webcams. Let me not lie- Professional cameras aren’t that easy to handle. You should have prior experience and a fair bit of expertise to produce professional quality live video streams by using professional cameras. Unless and until you have a good learning curve, ‘ease of use’ doesn’t go hand-in-hand with versatility.
Again, professional HDMI and SDI cameras are not gift wrapped entities. They cost you around $800 or perhaps more than a thousand dollars. Be ready to incur additional expenses for a super quality capture card.
If you have any doubts or concerns, feel free to drop a line or two in the comments section. I will be happy to help you. Keep watching this space for insights on live streaming and cameras for live streaming. My best wishes are with you and your live streaming venture. Cheers!
