How to make chromeak do it yourself
Want to feel yourself a character of a Hollywood movie? Take the instrument "Chromacia"! Together with him, you quickly understand how to replace the background on video and you can combine several layers of video in one frame. From this article, you will learn how to create a chromium with your own hands, properly organize the removal process and competently mount the material later using the video editor.
Learn to replace the background in the video! Look at a short lesson:
Production of chromaque at home
To create a video with the ability to replace the background, you will surely need a monochrome blue or green background. You can buy ready for several thousand rubles or save this money and make the background yourself. You can use green or blue paper or cloth as a material.
In the first version, everything is simple: you just need to gently glue the sheets. If you decide to work with a cloth, then when choosing a material, make sure that it is matte. To create Chroma Key for streaming and during other filming, it is best to use a gabardine or other dense fabric.
It is extremely recommended to choose materials with a "brilliant" surface, since it will reflect the light and as a result, when processing the captured video, you will have problems with the separation background. Make sure that after installing Bluskrin or Grinskrin, it was smooth without folds and beggars.
Before shooting, pay attention to the lighting setting. It must be uniform: this can be achieved by setting two light sources on the sides and one in front and behind.
How to make a chromacy effect: post-processing
Do not hurry to download a complex software that is used by professional installations: all the necessary tools can be found in the Russian-speaking program for editing the video "video formation".
The process of replacing the background in the editor is thought out to the easiest things, so you can quickly cope with the task. Follow the prompts: Sequentially perform a few simple steps and save the processed material in a convenient form. You can download "Video editing" with chromaker on our website.
Step 1. Run the program. In the start menu, click on the "Chromacia" button. Load the roller to the workspace you want to edit. Do not forget that this video should be removed on a monochrome background! Otherwise, replace the background is simply not possible.
Step 2. Add a new background. After the software, will offer to upload a file that will continue as a new substrate. It can be any video or image from PC.
Step 3. Select a color to replace. Just click on the background, the program will remember your choice and automatically remove the one-photon substrate when moving to the next step. Do not panic if it is randomly identified not the same color - just select a new one.
Step 4. Configure the layer connection process. You have almost learned how to make chromassed yourself - it remains only to adjust the position of the video. You can move it left, right, down or up, and even increase or decrease. If a previously removed green background is visible around the cut out figure, then experiment with the parameters "tolerance" and "mixing" on the left pane.
Step 5. Improve the material. The background is replaced! Video editing is also a convenient video for cutting video! Further, if you wish, you can adjust the duration by cutting out extra scenes at the beginning and end: just designate new boundaries using black markers and click "Next". The program will automatically save the changes.
You can also replace sound in video or add background music. Load any track from your computer or select a suitable ringtone from the built-in collection of collection, and then adjust the volume and go to the last, sixth, step.
Step 6. Save the video. You were able to make homely chromium, it remains only to export the processed material from the program in a convenient way to you. You can create an HD video or video in AVI format, prepare a video file for viewing from screens of phones and players or adapt it to download to popular video hosting: YouTube, Yandex.Video, Vimeo and others.
After you can open a video in the editor and improve it with the help of other tools provided in the "video edge". Add text and graphics on top of the video detector, use effects to roller or improve quality manually, accelerate the video taken, glue with other files and add impressive transitions between them, replace the sound.
Now you know how to remove the green background and replace it on any other. Take advantage of the knowledge gained in practice and mount a high-quality film with Hollywood effects right at home!
Chromaey, if anyone else has heard, is a special technology that allows you to replace the background and some items captured on video. Without her, by the way, no modern fighter or fiction is done (did you really think that the actors actually fly on dragons and go into open space? 😉).
To date, the chromake technology can not only use professional film director, but also the usual PC users. You can also sit at your computer (for example) to be somewhere in another country, in the jungle among dangerous snakes!
Moreover, if people who will show their videos, not very sophisticated PC users, most likely they will simply figure them out!
2 Examples of the use of chromacea (now it is clear what is we talking about?)
To get started, it is not necessary to start a lot: a monophotional canvas of paper or tissue (usually used green, but you can also be any other), some camera (you can use the phone, consulting it in a tripod) and specials. BY.
Below I will show all the specifics on the example ...
Example of using chromakes (by steps)
When creating and processing a video file
In order to be able to replace the background - it should be monophonic. Typically use green (or blue) color, because There is no such color on the skin and human hair (i.e., a clear line should be visible between the background and object). To start acquaintance with the chromaque technology (for home video), in principle, any paper or tissue canvas.
By the way! You can buy a green canvas in Chinese online stores. Question price for a small canvase 500-1000 rubles.
An example of a record with a chromaker
Main conditions :
- It is necessary to ensure that the cloth is behind you and "climb" fully in the frame (so that later you have had to cut the edges of the video);
- It is extremely desirable that the canvas be evenly illuminated without glare;
- The canvas should be smooth, without folds and dents.
The canvas completely in the frame
In general, video shooting is a whole "science", and not one book is dedicated to this. Therefore, I don't stop here anymore ...
We will assume that the video you still followed (or somewhere downloaded ready-made video, and want to change it).
Selection of software creation
To start working with the chromaker and the rapid change of the background - would recommend to try the program "Video Installation" (I will show your example in it). It is very simple, effective and allows you to get enough high-quality video.
Advantages (within our task):
- The presence of a simple step-by-step master (running through the screenshots of this article - you can easily make sure of it);
- The ability to detailed adjustment when replacing the background (position, scale, transparency, sharpness, etc.);
- Fully Russian interface;
- Support for all popular video formats (AVI, MPG, MP4, WMV, etc.).
After installing and starting the program, the window will be presented with a proposal to create a new project. Immediately select Option "Chromacey" (See Example below).
Choose tool Chromacia
Select video to replace the background
Now you need to specify a detached video with a monophonic background. In my case, it will be a running girl (by the way, it is not necessary to cut it up to the length - this can be done in the following steps).
After click "Further" . Example below.
Selection of video with monophonic color
Specifying a new background
Then you need to specify a new background: a picture or video (it will be displayed instead of green cloth). In my example, I took an image from space.
Choosing a new background
Help the program to find the background to change
In this step, you need to specify the color of the web on the video (in my example it is green) - for this it is enough to simply click on any free place of the canvas. See Example below.
Indicate the color of the background
Now the most important step, here you need:
- Using the scaling tools, set the size of the object on the video and its location (see screen below, the girl was moved to the right);
- Shift sliders "Tolerance" и "Mixing" For the maximum quality replacement background (Settings are configured for each video individually) . It is these regulators that allow you to completely remove all the green "accommodation" that may remain after automatic combination.
Position, tolerance and mixing
Trimming video to the desired duration
In this step, you can manually specify from what minute (seconds) and what kind of video you need. For example, at the beginning and end of the video, small flaws can be observed, it is desirable to cut these parts from the main content ...
Duration of video
If you wish in the video, you can insert add. Music, change effects, and see how it all will look after saving the finished video.
Format selection to save video
Next, the program will ask you to specify the video format in which you want to compress and save the finished project. In most cases, it is recommended to select AVI option to view videos on PCs and video players.
Selection of compression format
After you can specify a codec, permission (frame size), quality (bit rate) and proceed to the compression procedure (saving).
The compression time depends on the quality of the source video, the characteristics of your device, selected codecs, etc.
To immediately, the difference was noticeable, I combined the screenshots from the source video and processed (after chromaque). As you can see, even at home, you can easily and quickly use various special effects that allow us to do chromium.
What we had and what happened (the video is open in the player)
When conversations on the network (replacement of the background online)
I note that the quality of the replacement of the background with online conversations - often leaves much to be desired (especially if you are specials. I did not prepare a one-photon cloth for your back).
Nevertheless, why not try?! 😉
Regarding new versions of Skype, it was possible to change the back background to the picture you need. Moreover, it is not at all necessary, so that you have a monophonic green color - the program allows you to change even the usual home furnishings.
This is just done : just open the program settings and go to the section "Sound and Video" . It will only remain choose the desired Camera And specify Picture (You can add something yours, if you do not like anything from the basic set of the program).

In ZOOM, such an option is hidden in the section "Virtual Background" In the main section of the settings. I note that for personal feelings in ZOOM, this feature works a little worse than in Skype (at least on my PC).

This method is suitable to change the background from the video from a webcam for any application! This is achieved by a simple scheme:
- Sets specials. app, say 👉 Manycam - It gets an image from a webcam and changes it "on the fly" (for example, add a new background 👇);
- After Manycam creates a virtual chamber that gives a modified image;
- Any other program (let's say, Skype) - gets this image from a virtual camera and transmits it to your interlocutor! 👌 And the quality is very high, which pleases!

Studio Chromaey do it yourself in and in their room - yes Easy!
For this, just a canvas itself, several illuminators (you can simple lamps) and a little smelting.)
Now we will analyze everything in steps:
1) Pick up the zone in your room so that you have in the reserve of the meter three in the width and meter three in length
Figure with a zone under household chromium
2) You will also need lighting lamps.
•At best, of course, there can be a soft boxes, but in the absence of anything you can do and simple lamps that are at hand.
•But an important point - it is necessary that very bright paws and preferably LED minimum and brightness are screwed into these lamps - 4000 Lumen
If there is a financial opportunity, then do not suck out to purchase this kind of searchlight:

He and the price is not too expensive, and the quality of the lighting is very high.
3) It is also necessary to purchase chromium for a home studio.
• Today on the Internet, many information that chromium can be made from anything, but it is not quite so. The fact is that the quality of shooting video will be very strong to suffer in the video will be ripples and the error that is then not corrected. For this, make an emphasis on the background for the video.
4) make a good focus on the camera
• Today, the viewer is very demanding and he needs the quality of video or even the photos with high resolution, it is desirable to take care of the purchase or acquisition of a high-quality camera with a minimum of 2500 pixels, and at best with a resolution of 4 K - this standard will still be very long Time is popular for this, believe the excess will not definitely.

You probably have seen how films on a green background are removed. The heroes do something, run, jump, and then we see how they do it in space or in some other fantastic environment. The process of replacing the background is called King, and the technique of combining two or more pictures is a chromaker (from English. Chroma Key - "Color Key"). I'll tell you how to make
Chromaee do it yourself
As you already understood, we will need background, light and program for replacing the background.
The background for chromakes is called Greencreen (from English. Green Screen is a green screen) or bluskrine (from the English. Blue Screen - blue screen), depending on the color. Suitable background can be bought at a price of $ 200 (the price is affected by the size of the background, the presence of racks and quality of the fabric). But since the article is called "Chromaei with your own hands", I will tell you how I did a background for chromaque.
- Like everyone, I knew that the fabric should be green, or rather a salad. But searched all the stores of the fabric in the city, I realized that I would not find the right shade. Therefore, so as not to throw out money for the wind, I bought a blue fabric, which is also great for chromacea.
- Why only blue and green?
As you already guessed, in the last stage of King, we will choose the color of the background "Pipette" and "Delete" this color from the picture. If the background color is, for example, red, then the face of actors will disappear with the background. And the blue and green, as it turned out - these are the most opposite colors of the skin.
As a person who has shot the chromium on a blue screen for several years, I can say the following: 2On the blue background, it is impossible to shoot blue things - for me it was a problem when I realized that half of my things - blue;
If your Actor is black, it is better to use a green screen.
What to do screen
My first screen was out of paper. I had no money for the fabric, and even more so on the professional screen. Therefore, I decided to buy paper of the format A4 of a salad color and glue it with a scotch. I did not find gas paper, so I bought white paper and salad markers. Oh yes, I was a persistent guy! In a few days, I painted with markers in a weapon color of paper with a total area of 3 m
. And it raised this work on a wooden frame. In general, the background turned out to be good, but the scotch, which I crossed the sheets among myself, threw the glare, which remained white points on the video. For some time I deleted them by hand, and then threw it this case and made a different background.
The second background was blue, and it would be of the fabric. I bought 6 meters of blue fabric, which was cut in half and sewed between him. As a result, I had a blue canvas 3mx2,8m. This screen I hung in my room over the curtains - the problem with racks was solved.
The first thing you understand when working with a chromaker: you need a lot of light. You must have a separate set of light for the screen so that there are no shadows on it. You should also have a shooting object away from the screen so that its shadow does not fall on the screen. You must ensure that the screen on the video looks as many times as possible. Make sure that there is neither too grooved areas or darkened. This will help make better King.
As for the illumination of the shooting object, think about the final result. Where are you moving your hero? What light sources will shine on it in a virtual environment? Accordingly, it is necessary to illuminate your hero, so that when replacing the background, random glare or shadows did not cause questions. Also, if it is possible and corresponds to the estimated surrounding, highlight the object of shooting by the backlight (the light is located on the camera and highlights the "invisible" side of the object) - so you make a picture more volume and better separate your hero from the background.
Follow the edges of the frame!
First, your green (or blue) screen must reach the edges of the frame so that you can cut the subject, even if it is on the edge of the frame.
Secondly, if you take off the person, make sure that he will not wave a lot of hands. If the frames of the frame will dry up his hands, you will not be able to move it on the frame, when replace the background.
IV. Replacement background.
I make a replacement background in Adobe After Effect. There is a very good effect called Keylight. With this effect, you can make a very high-quality clipping. I learned this from Andrew Kramer, which you can always find on VideoOcopilot.net. On the Internet there is it a video tutorial on chroma in After Effect. I suggest you to see it (the lesson starts at 2:30).
Perhaps this is all on the topic "Chromaci do it yourself". Now nothing holds back to build your film studio at home or in the garage. Throw in the comments links to what you have happened. This is what I once did:
Here, the general rule is the more, the better, but in moderation. Of course you can shoot and on the patch 2 * 2 meters, putting a mobile chromium chromium chromium, but what can you fit into the frame except the "talking head"? Yes, and with the light will be problems. On the other hand, to shoot the same speaker in the pavilion with the size of the hangar - also not entirely appropriate. It is desirable that in the room or at least in the chromium zone there was no windows, because the sun does not ask the shooting schedule. Or you have to close the windows with plywood shields with painted black paint. Black paint is desirable to paint the ceiling. Mobile chromacia Talking head in close room It is too close to a person to the background, does not have a context light and throws the shadow Therefore, decide for what filming you need a chromium zone and do not skimp on meters. The minimum necessary for shooting one or two static actors into growth will be acceptable 5 * 4 meters. And 3 height, and better than 4 meters. These sizes will allow to shoot
with two cameras And place light devices from above. The lack of shooting space creates additional problems that will subsequently have to deal with POSTOPALKSHNA . In order not to create an extra problem, it is necessary to equip such a space in which it would be comfortable to work.
* Distance from green background to object
did not discard the shadows on the background
And so that the parasitic reflex (green reflection of the background) did not get on the clothes. And also it was possible to put the filling and control light so that the devices were not in the frame.
⊗* The distance between the camera and the object should be such that it was possible to comfortably arrange the instruments of the filling, drawing, antyrflex light, so that they do not fall into the frame.
Proportions and trains for work and illumination of chromium in defective spaces
In most cases, a green color is used for chromium, since it is a smaller statistic present in the clothes of people and skin shades. But sometimes a blue background is used, in cases where the clothes of the heroes have green colors. A green color on a green background will simply proceed - that is, it will disappear along with the background. Cycllorian chromium chromium

Tissue The background is more convenient and more practical, although more expensive. He is the most universal. The fabric background is compactly folded, erased, strokes, it is perfectly stitched to create a chromaker of large sizes. The width of the canvas is 6 meters and more, attached at least nails on the wall - the main thing to the folds there are no bags (from practice - it is better to top and bottom often touching a narrow strip of plywood or rake and then fasten this design - it will hang smoothly and stretched). The disadvantage of the fabric is that on it, no matter how hard they try to pull it and disappear - there are always pleats .... With folds, you can work, but what is less than them, the evenly the background is stretched, the more uniform is highlighted and the peeling occurs without additional manipulations on the post-sales. Fabric background can be hung in a smooth bend in the corner.
Fabric chromayaca background in studio
A very good option for the floor, as practice has shown - the usual "soft floor" from EVA material (foam) used in children's rooms. Tiles of green color perfectly hide and wash if someone stained with dirty shoes (although the shoes should be exclusively replaceable or medical boots in the chromium zone). Includes there is a side to hide the transition to the wall. The only minus is no heels and legs of chairs, and tables. Penka is pushing. Soft floor for children
- Good consumable material, but not at all cheap. Also, not every green paint is suitable. The main thing - the paint should not be picked up. Therefore, they use special expensive compositions of green, less often blue, for example covered with chromium cycloras in Moscow - they do not give glare. The paint is convenient when you need to quickly paint or when it is not possible to cover the fabric. The furniture is also successfully painted in the color of chromium. Paint and additional designs: stairs, cubes, tables, chairs - paint in order to replace the painted objects to replace the painted objects on the designed 3D models.

Probably the main criterion of high-quality and successful video shooting, where to start shooting on a chromium - it is

If it is not possible to purchase a suspension lighting system, you will have to hang appliances on the ceiling fixedly, which is much less convenient or use the devices on the racks (if not allowed the height of the room).

To shoot a dynamic scene, it is also necessary to use a dynamically changing lighting of the moving object. If a person moves in a frame, it comes out of the lighting zone of the content light, from the zone of the suppression of the parasitic reflex, from the frontal fill zone - goes into the shadow or in the Peresvet. To solve the problem there are two ways:
* Lighting devices for the displacement zone or group of people so that the lighting at different points of the scene has the same result. In the conditions of a close studio, and even more so just a chromium zone, for a group of people to achieve the desired result is almost impossible. * Lighting and move the necessary lighting devices simultaneously with the movement of a person or a group of people, so that in all points on the stage the result was uniform. This is the most commonly used way to work on chromaeee in closer conditions in the studio or with group filming.
