Fast Tip: Mastering Green Screen Techniques

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.

• 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.

Conclusion

Green screen photography produces excellent results, and its ease of use makes it indispensable for videographers of all levels. In this guide, we’ve discussed chroma key technology, its role in the industry, and how to apply it to your craft to elevate visual content.

Maximizing Impact: 5 Secrets for Increasing Your Video’ Writes

5 Tips to Get More Views with YouTube Optimization [Free Checklist]

We all want our videos to get a lot of views, and in turn, lead to more subscribers. In order to do so, we have to prepare it for success. If you are hoping to optimize a video after it has already been published to YouTube, then you aren’t going to get the best result, because much of optimization is done before the video is even shot.a

In this article, we will give you a checklist , which you should have with you at the very beginning of creating a YouTube video: the ideation stage. As you go through your process, check off each task. By doing so, you can ensure that you have given the video the best chance to rank high and be discovered.

How to Optimize Your Video to Rank Higher on YouTube?

1. Keep Your Audience’s Attention
2. Do Keyword Research
3. Engage Your Audience
4. Upload YouTube Video in Proper Length

1. Keep Your Audience’s Attention:

Even though your view count is going up, it doesn’t mean your audience is watching your video. And if they are not, then YouTube is going to consider your video less valuable and therefore, lowering its rank.

Audience Retention is an important metric to keep an eye on after every video you’ve published.

Before you start your next project, take a look back at the Audience Retention of your previous videos.

1. Enter YouTube Studio in your channel
2. Access to Analytics
3. Select the video you want to review
4. Click into engagement
5. See where a dip in watch time

What is Good Audience Retention?

If you want to see how your Audience Retention is performing, the Average Percentage Viewed will give you a broad perspective. The higher the percentage, the more people are watching your entire video.

If you get above 60% Average Percentage Viewed, you should feel very proud. In our modern world with our short attention span, that is considered good retention.

In the example above, we see that on average, a viewer will only see 44% of the video. For the video below, we see that it only has 30% of the video viewed. Overall, the first video is performing better.

There is also a dip that happens at the beginning in the second example, which indicates that viewers are skipping forward and about 20% then deciding it’s not worth continuing. It’s good data to help you improve your introduction and the hook.

If there is important information that you are presenting at a given point and in the Audience Retention you see that only a small percentage of your viewers actually see it, then for the next video, you might want to position the details in a different point in the video.

How to Improve Audience Retention

Here are a few ways you can retain your audience’s attention if you noticed a drop in viewership:

- Film a hook (introduce your video to let the audience know what to expect)

- Add b-roll (having supplemental footage to cut to makes your video more interesting to watch)

- Have a co-host (Having someone on screen gives the video more dynamic interactions)

- Edit out the unimportant stuff

- Write a conclusion (having a conclusion prepared will allow you to transition from the content of the video to the call to action without the audience even knowing) See this example by PolyMatter below and notice how seamless their ending is.

If you have a video that is doing a good job retaining the audience, then replicate it. If there isn’t, keep experimenting with new structures. Improving audience retention is not simply important for your ranking, but it will affirm that you are building quality videos.

Knowing how to structure your video will allow you to be strategic as you build out your content.

2. Do Keyword Research:

Many viewers find YouTube videos via search, and if you aren’t using the appropriate keywords, then YouTube won’t be able to identify your content and display it for your viewers.

Where Do Keywords Appear on YouTube?

- Title: Have keywords at the beginning of the title and limit them up to approximately 60 characters so it appears in full in search.

- Tags: Include 10-15 tags from general keywords to more specific.

- Descriptions: Put important information and keywords at the beginning of the description so both searcher and the search engine understands what the video is about.

Why Keywords Matter

keyword arrangement is an integral part of YouTube optimization because the robots behind YouTube don’t associate the value of the actual video content with what the viewer is actually seeking. You should pay attention to the relevance of keywords.

Even when you add closed captions, it doesn’t mean the best keywords are present to the Youtube search engine when we speak.

That is why it is important to know your audience and what words and phrases they are going to use to search for your video.

Here is how you can see what keywords were used to find your video:

1. Enter YouTube Studio in your channel
2. Access Analytics
3. Select Reach
4. Click into Traffic Source
5. Click Traffic Source: YouTube Search

If you want to find some new keywords for your upcoming video, you will need to do some research.

1. Enter Keywords You Want to Rank for In YouTube Search: This allows you to see what the most popular phrases are in the YouTube search engine.

2. Study the Competitors: See which videos are ranking high for your search term. Use a tool called VidIQ to see the keywords that the top videos are performing.

3. Search for Related Keywords and Evaluate Relevancy: A tool called Ubersuggest can help you find related keywords and allow you to identify the search volume, cost per click (aka CPC is used for determining the budget for paid search), and the competitiveness of the word or phrase.

Search volume: The number of searches with that particular keyword. The higher the number the more popular it is. You should aim to use keywords with a high search volume.

Keyword competition score: This score is usually indicated by a number and it represents how difficult it is for a keyword to rank due to other pages already ranking for that word or phrase. You want to find a keyword with a low competition score.

Pro tip: The best combination is high search volume and low competition score. But if you can’t get that perfect mix, go for the low competitive score, as it will give you a better chance to rank, even if it isn’t searched as often.

4. Come Up With Content Related to Those Keywords: To come up with topic ideas around a keyword, you can use a tool called Answer the Public , which gives you all the most popular questions searched online.

3. Engage Your Audience:

It’s been highly discussed on forums all over the Internet, and there appears to be a strong correlation between YouTube video ranking and the number of likes, dislikes, and comments the video received.

While YouTube itself might not be using the number of likes and comments to determine where your video rank, having high engagement allows your video to be discovered through other means.

Here is an example of how it would work:

- A YouTuber with 100,000 subscribers views your video and likes it

- Then your video might be visible to a fraction of those 100,000 subscribers.

- Boom! Domino effect!

- More people will see your video and like it, increasing your network of viewers and your watch time, which is one of the main factors that YouTube takes into consideration.

Get engagements with a call to action:

- Don’t be afraid to ask for an engagement at the beginning of the video to avoid fall off on retention.

- Encourage them to leave a comment or start a discussion by asking a question at the end of your video.

- Monitor comments and responds to them so you can build a relationship with your audience over time.

It’s all about creating a community and that is what YouTube encourages.

4. Upload YouTube Video in Proper Length:

YouTube puts a lot of weight on watch time, and in addition to that, it puts more weight on session watch time.

Session watch time is counted when people watch your video and then continue to watch others, it doesn’t have to be your own. The more time people spend watching YouTube videos, as a result of your content, the more likely YouTube will increase your ranking.

Since YouTube puts importance on time spent watching videos, the length of your video will play a key role.

If you have 5 videos and all of them are a minute long, a 100% watch through will only get you 5 minutes total.

However, if you have 1 video that is 20 minutes, and an average viewer only watches half of it, then you have an average watch time of over 10 minutes. That’s more than double what your five short videos can do. This longer video is worth more. However, if that 20-minute video is really boring and people drop off in the first minute, then it’s not any better than 1 of the 5 short videos.

If your format allows, go for a longer video instead of a shorter one. But the most important thing is that you can keep people watching your videos: so use end screen and playlist links to keep them engaged.

End screen: Pick related videos for your audience, so they know exactly what they should watch next. You can even create a background template for your end screens .

Playlist: If you have multiple videos that fit a specific topic, add them to a playlist so the viewer can enjoy them all in one viewing.

Key Takeaways:

1. Use Audience Retention to better understand how to structure your video for the best results.
2. Perform Keyword Research to find the keywords that your competitors are using and your audience is searching for.
3. Increasing Subscribers gets your video in front of more people the moment it is published.
4. Encourage Comments and respond to establish a relationship with your viewers.
5. Ensure that Viewers Continue Watching videos on YouTube after they finish watching yours.

Other Things That Affects Your YouTube Ranking

Except for the above-mentioned factors, there are also other issues that affect the ranking of your YouTube video. YouTube has stated that the number of subscribers doesn’t play a key role in your video ranking.

For example, if a YouTuber has a million subscribers and then overnight they lose 100 thousand, a video they had ranking number 1 will still be ranked number 1.

However, the number of subscribers has a lot of indirect effects on your channel.

- Subscribers know the moment your video is published

- Subscribers will watch your video in the first week (YouTube will rank your video higher if they see a lift in the first week of publishing)

- YouTube put a higher value on subscribers than views and social shares, because it’s harder to fake subscribers

Growing subscribers take time and effort, and even though it shouldn’t be your main focus, there are tactics you can do to gain more subscribers .
