You might have noticed that, when you post a video, you get to choose how you want to copyright it: standard license, or creative commons. You’ve also probably noticed that when you looking for royalty-free music or stock footage a lot of it is licensed through creative commons.
So, what exactly are creative commons ?
To hold the copyright to a creative work means that you own it, and anybody who wants to use your work for anything (i.e. uses a song you composed in their YouTube video) has to do so on your terms. When you license your work through creative commons you do not give up your rights to your creative work (a common misconception).
When you use a creative commons license you are outlining the terms under which other creators are allowed to use your creations in their projects for free if they credit you for your work.
If you do not want anyone using your work for free in any context, you stick to traditional copyrighting.
But if you’ve created a piece of music, a photograph, or a clip that you wouldn’t mind other people using, potentially as a way to get your name out there, you might want to consider creative commons.
There are 6 different creative commons licenses. Which is right for you will depend on your answers to these two questions:
Are you okay with a creator making money off of something they create using your work?
Are you okay with a creator producing a derivative of your work?
To say ‘no derivatives’ is to say ‘I’m okay with people using it, so long as they don’t change it’. One example of a derivative is a techno remix of a song. If you are alright with other creators making derivatives of your work, you may also want to require them to ‘ShareAlike’. ShareAlike means that the creator of that techno remix of your song has to use the same creative commons license you used for your original to distribute the remix.
An example of a derivative someone might make of a YouTube video would be auto-tuning it to make a song or cutting up your video to make one that’s just ‘the funny parts’.
Here are the 6 creative commons licenses, and a chart you can use as a quick reference tool.
Attribution – CC BY
If you’re using music or other media with this license, all you need to do is credit the artist.
If you license your video this way, people can do whatever they like with any element of it (video or sound) so long as they credit you. I.e. if someone wanted to mute your clips and use you as stock footage in a bigger project, they could.
Attribution-ShareAlike – CC BY-SA
If you use music, photos, or any other media licensed this way, then you must both credit the artist and license your video this same way. Meaning, you can’t use YouTube’s standard license and must instead allow for others to use your work the way you are using the licensed media.
If you apply this license to your video, you’re saying you don’t mind people using all or portions of your video for their project so long as they allow others to use their work in the same way.
Attribution-NoDerivs – CC BY-ND
This one can get tricky.
Essentially, you can use media licensed this way so long as you don’t alter it or create a different version. For example, you can’t take a song licensed this way and use it in a mashup with another song. That part is clear. Where it gets tricky is when you want to use a song in your video.
Under normal copyright rules, using a royalty-free song in the background of your video would not count as creating a derivative. The definition of derivative according to creative commons is a bit broader and includes ‘syncing’. This means you can’t take an ‘Attribution-NoDerivs’ song and create any kind of music video for it.
For example, you can’t edit clips of yourself snowboarding so that they’re in sync with a song that has this license.
Whether or not you can play the song in the background of your vlog while you are speaking can be a bit of a grey area. In theory, it shouldn’t be a problem, but if you’re accessing the music through a social site like SoundCloud then it might be best to ask the artist first.
There’s no reason to license your YouTube videos this way. If people cannot alter your video, all that’s left is for them to repost it. Even though they’d also be crediting you, they’d still essentially be stealing views and ad revenue from your original video.
Attribution-NonCommercial – CC BY-NC
If you’re using stock footage, music, or stock photos licensed this way then you should still be able to monetize your video. YouTube monetization and commercial use are different things. However, there is a lot of confusion about this issue, and chances are the rights holder intends for this license to mean ‘no monetization’.
What you definitely could not do with a NonCommercial license is to use the song/other media in an actual commercial for a product, including product placement that a brand is paying you for.
If you license your video this way, people can use it in whatever way they like so long as they credit you and don’t try to make money off of it. Once again, that doesn’t mean they can’t use it in a YouTube video which they monetize because, technically, they’d be making money off of the ad that ran ahead of the video and not the video itself.
The thing to be careful of with this license is that it’s not ‘ShareAlike’. So, if you license your video this way somebody could use your clips as stock footage and then provide them - as part of their project – for free to a third person to use in a project they were making money off of.
Attribution-NonCommercial-ShareAlike – CC BY-NC-SA
Music and other media with an ‘Attribution-NonCommercial-ShareAlike’ license can be used in and altered for your videos, so long as you aren’t making money off those videos. You must also use this same license for the video you create using elements licensed this way.
If you license your video this way, people can use it or a portion of it in their project if they credit you. They must also use this same license for their video if they do. This protects you from the situation where a third person who never licensed your original content is making money off of it.
Attribution-NonCommercial-NoDerivs – CC BY-NC-ND
There aren’t many situations where you would be using media licensed this way in your YouTube videos. You can’t alter it, sync videos to it, or make money from any video that uses it.
You also probably shouldn’t use this license for your videos. ‘NoDerivs’ means there are not many ways people could use your content, except to repost full videos and steal your views.

Pro Tips for Utilizing Green Screen Effects Professionally
The world of video-making owes much of its magic to small leaps of innovation. One of these leaps is the use of the chroma key background, which most people know by the more colloquial term—green screen.
Chroma key, also known as green screen or blue screen, is a cool hack for seamless visual storytelling, allowing content creators to replace backgrounds with any image or video they want. This technique is widely embraced in film, television, and online content, and has opened the door to limitless creative possibilities. Aside from its ability to maximize creativity, it is also cheap to employ and convenient to set up, which has made it a staple for everyone who works with visuals.
In this simple guide, we’ll delve into the fundamentals of the chroma key effect, how it is used for video making, and how to leverage that as you perfect your visual content.

How Does Chroma Key Work?
Chroma Keying is done by singling out a specific color (usually green or blue) from the foreground, removing it, and replacing it with a different background (for example, a sunset). This process typically follows a series of steps:
- Background Selection:
A solid, single-color background, often green or blue, that contrasts well with the subject must be used. The color chosen should not be present in the subject or any props in the camera field to avoid unintentional transparency.
- Color Keying:
This requires the use of specialized visual effects software to key out the chosen color. The green or blue background is designated as transparent, making everything of that color see-through. The software distinguishes between the keyed color and the subject, creating a mask for the transparent areas.
- Foreground Filming:
This involves filming the subject against the live chroma key background. During filming, the chosen background color (green or blue) won’t appear in the final result due to its transparency. The subject is captured as if separately from the isolated background.
- Post-Processing:
In post-production processing, the editor takes the keyed-out color and replaces it with the new background of their choice. This step creates the illusion that the subject is in a different setting or environment. The transparent areas become filled with the chosen background which, if done right, results in a cohesive and visually appealing composition.
Why Green?
Theoretically, the chroma key background can be any solid color. However, the most commonly used colors are studio blue and bright green, with the latter far more common.
The choice of background color depends on the specific requirements of the production and the colors present in the scenes being filmed.

Contrast
The less similar your chosen background color is to natural skin tones, the easier to isolate and replace in your footage. Bright green provides a strong contrast to most human skin tones and is less likely to be present in costumes or natural surroundings, making it easier to isolate subjects during the color separation.
Luminance
The color green emits light with greater intensity than blue, allowing for far more effective isolation by cameras during filming. This also means that blue screens demand increased lighting for proper exposure compared to green. This situation may be less than ideal if you lack powerful lighting or you don’t have the big bucks for them.
Digital Sensors
Many digital cameras and sensors are more sensitive to green wavelengths, resulting in cleaner and more accurate color keying during post-processing. Modern technology has also evolved to optimize for a green background, making it a more practical choice for the chroma key effect.
Wardrobe and Set Design
Bright green occurs less naturally in costumes and set designs than other colors, making green the optimal choice for reducing the likelihood of color spill and keying issues. However, if you know your scene will have lots of green, it is probably best to film with a blue screen, so there’s less risk of color spill and less post-production work.
Setting up Your Own Chroma Key Studio
Setting up your chroma key is convenient and straightforward, but there are some key factors to consider while setting up to ensure maximal performance.
Choosing the Right Background Color
The first step in the chroma key setup is selecting the right background color to be keyed out. This choice determines your effective color separation and ensures a smooth keying process during editing. Choosing a chroma-key background color that contrasts distinctly with the subject’s colors is essential for effective color separation. This prevents unintentional transparency, color spill, and ensures a polished final result.
Lighting Considerations
Lighting is an important part of the chroma-keying process. Bold, uniform, and consistent lighting on both the subject and the background makes it easy to delineate one from the other fully. This minimizes shadows and variations in color, creating a smooth and seamless keying process. Multiple diffuse lights from different angles are often used to illuminate the green screen evenly.
Positioning/Camera
Proper subject and camera placement are necessary to ensure an even color-keying process during post-production. To prevent shadow interference, the green screen should be smooth, tense, and without wrinkles or shadows.
High-quality cameras are essential every time, especially for chroma keying. Images with better definition are easier to key, so camera quality significantly affects the outcome. Even if your camera isn’t the best, merely shooting well can ensure a clean color-keying process during editing, resulting in professional-looking visuals.
Recording Tips for Chroma Key
- Proper Lighting
Maintaining uniform and well-defined lighting during recording is essential for a successful chroma-keying process. This consistency ensures a seamless keying process during post-production.
- Keep Distance from the Green Screen
The optimal distance between the subject and the green screen minimizes color spill and allows for natural movements. Proper distance between subject and background allows for easier isolation of the background and much smoother post-editing. A recommended starting point for the issue is around 6 to 10 feet from the background.
- Subjects and Clothing
As mentioned before, the choice of costume for Selecting appropriate clothing that doesn’t match the chroma key color prevents transparency issues. Subjects also have to be positioned in such a way that there is minimal light interference and reflection. These contribute to a flawless chroma key outcome.
/a>3 Basic Troubleshooting Strategies
- Color Spill
Sometimes, reflected light from your green background can be cast on your subject and may remain so when the background light is keyed out. This phenomenon is known as a color spill. It is usually because of uneven lighting or shooting around reflecting surfaces. Avoiding spill can differentiate between good and lousy chroma key aftereffects.
Human hair is one area where color spill can show up unsuspectingly. Due to the translucency of hair, it is common for some unintended light to seep through. This allows some background visibility, which you do not want with a chroma key. This is especially notable with lighter hair colors like blond hair.
There are ways to account for this. Many video-editing software have features such as spill suppression and screen matte adjustments that can enhance the final footage. Specialized plugins also go a long way in ensuring minimizing spill. Addressing spill correction tackles unwanted green artifacts and ensures a clean keying process.
- Poor Lighting
Suboptimal green screen lighting can lead to inconsistencies in keying and editing, undermining your product. One way to avoid this is to light the screen and subject separately. Another tip, although expensive, is using multiple diffuse light sources and trying to maintain even lighting across every square foot of your scene. Super bright or dark spots can ruin your output, so it’s worth the extra effort if you don’t want to deal with problematic post-production.
- Poorly Refined Edges
Chroma keying should leave your videos with crisp, defined, natural-looking edges. But post-production editing can make all the difference if it doesn’t come out to your taste. Softening and refining edges make a smoother transition between the foreground object and the new background. Light adjustments to edge thickness and screen matte settings can also help enhance overall visual quality and add finesse to your work.

How Does Chroma Key Work?
Chroma Keying is done by singling out a specific color (usually green or blue) from the foreground, removing it, and replacing it with a different background (for example, a sunset). This process typically follows a series of steps:
- Background Selection:
A solid, single-color background, often green or blue, that contrasts well with the subject must be used. The color chosen should not be present in the subject or any props in the camera field to avoid unintentional transparency.
- Color Keying:
This requires the use of specialized visual effects software to key out the chosen color. The green or blue background is designated as transparent, making everything of that color see-through. The software distinguishes between the keyed color and the subject, creating a mask for the transparent areas.
- Foreground Filming:
This involves filming the subject against the live chroma key background. During filming, the chosen background color (green or blue) won’t appear in the final result due to its transparency. The subject is captured as if separately from the isolated background.
- Post-Processing:
In post-production processing, the editor takes the keyed-out color and replaces it with the new background of their choice. This step creates the illusion that the subject is in a different setting or environment. The transparent areas become filled with the chosen background which, if done right, results in a cohesive and visually appealing composition.

Why Green?
Theoretically, the chroma key background can be any solid color. However, the most commonly used colors are studio blue and bright green, with the latter far more common.
The choice of background color depends on the specific requirements of the production and the colors present in the scenes being filmed.

Contrast
The less similar your chosen background color is to natural skin tones, the easier to isolate and replace in your footage. Bright green provides a strong contrast to most human skin tones and is less likely to be present in costumes or natural surroundings, making it easier to isolate subjects during the color separation.
Luminance
The color green emits light with greater intensity than blue, allowing for far more effective isolation by cameras during filming. This also means that blue screens demand increased lighting for proper exposure compared to green. This situation may be less than ideal if you lack powerful lighting or you don’t have the big bucks for them.
Digital Sensors
Many digital cameras and sensors are more sensitive to green wavelengths, resulting in cleaner and more accurate color keying during post-processing. Modern technology has also evolved to optimize for a green background, making it a more practical choice for the chroma key effect.
Wardrobe and Set Design
Bright green occurs less naturally in costumes and set designs than other colors, making green the optimal choice for reducing the likelihood of color spill and keying issues. However, if you know your scene will have lots of green, it is probably best to film with a blue screen, so there’s less risk of color spill and less post-production work.

Setting up your chroma key is convenient and straightforward, but there are some key factors to consider while setting up to ensure maximal performance.
Choosing the Right Background Color
The first step in the chroma key setup is selecting the right background color to be keyed out. This choice determines your effective color separation and ensures a smooth keying process during editing. Choosing a chroma-key background color that contrasts distinctly with the subject’s colors is essential for effective color separation. This prevents unintentional transparency, color spill, and ensures a polished final result.
Lighting Considerations
Lighting is an important part of the chroma-keying process. Bold, uniform, and consistent lighting on both the subject and the background makes it easy to delineate one from the other fully. This minimizes shadows and variations in color, creating a smooth and seamless keying process. Multiple diffuse lights from different angles are often used to illuminate the green screen evenly.
Positioning/Camera
Proper subject and camera placement are necessary to ensure an even color-keying process during post-production. To prevent shadow interference, the green screen should be smooth, tense, and without wrinkles or shadows.
High-quality cameras are essential every time, especially for chroma keying. Images with better definition are easier to key, so camera quality significantly affects the outcome. Even if your camera isn’t the best, merely shooting well can ensure a clean color-keying process during editing, resulting in professional-looking visuals.

- Proper Lighting
Maintaining uniform and well-defined lighting during recording is essential for a successful chroma-keying process. This consistency ensures a seamless keying process during post-production.
- Keep Distance from the Green Screen
The optimal distance between the subject and the green screen minimizes color spill and allows for natural movements. Proper distance between subject and background allows for easier isolation of the background and much smoother post-editing. A recommended starting point for the issue is around 6 to 10 feet from the background.
- Subjects and Clothing
As mentioned before, the choice of costume for Selecting appropriate clothing that doesn’t match the chroma key color prevents transparency issues. Subjects also have to be positioned in such a way that there is minimal light interference and reflection. These contribute to a flawless chroma key outcome.
3 Basic Troubleshooting Strategies
- Color Spill
Sometimes, reflected light from your green background can be cast on your subject and may remain so when the background light is keyed out. This phenomenon is known as a color spill. It is usually because of uneven lighting or shooting around reflecting surfaces. Avoiding spill can differentiate between good and lousy chroma key aftereffects.
Human hair is one area where color spill can show up unsuspectingly. Due to the translucency of hair, it is common for some unintended light to seep through. This allows some background visibility, which you do not want with a chroma key. This is especially notable with lighter hair colors like blond hair.
There are ways to account for this. Many video-editing software have features such as spill suppression and screen matte adjustments that can enhance the final footage. Specialized plugins also go a long way in ensuring minimizing spill. Addressing spill correction tackles unwanted green artifacts and ensures a clean keying process.
- Poor Lighting
Suboptimal green screen lighting can lead to inconsistencies in keying and editing, undermining your product. One way to avoid this is to light the screen and subject separately. Another tip, although expensive, is using multiple diffuse light sources and trying to maintain even lighting across every square foot of your scene. Super bright or dark spots can ruin your output, so it’s worth the extra effort if you don’t want to deal with problematic post-production.
- Poorly Refined Edges
Chroma keying should leave your videos with crisp, defined, natural-looking edges. But post-production editing can make all the difference if it doesn’t come out to your taste. Softening and refining edges make a smoother transition between the foreground object and the new background. Light adjustments to edge thickness and screen matte settings can also help enhance overall visual quality and add finesse to your work.
