Video Compositing: How to Work With Alpha Mattes and Alpha Channels
If you’ve spent any time working with green screens or green-screen footage, you’re aware of how much you can do when you have an isolated subject to work with. This goes doubly for clips with alpha mattes or alpha channels, because you don’t need to worry about keying out or removing anything (as it’s removed already), finishing part of your work before you even put it into your project.
But how is it removed? The key is in the channels. Three main channels contain all the color information: red, green, and blue (RGB). There is also a fourth channel that’s invisible and contains transparency information, called the alpha channel.
This allows you to have transparent information that doesn’t affect any of the colors in the video. Here is an example of a clip with an alpha channel. Note the checkered background, indicating that it’s transparent:
Dragon Flying and Breathing Fire, Looped Clip with Alpha Channel by Zuxela
(Alpha) mattes, on the other hand, are layers that tell the software which layer or area within a layer is where the transparent parts are. Many mattes are displayed as black and white, with black being the transparent area and white being the opaque area. A lot of times, the alpha channel is the matte, but not always — that’s why I put “alpha” in parenthesis. You can make a matte in place of the alpha channel in situations where a matte works better, or if the file doesn’t actually have an alpha channel built in. Here’s an example of a clip with an alpha matte. Note the black and white section in the back half, which tells your editing software which area is transparent:
4K Money: Slow Motion Scattering on White, Alpha Matte by Arsgera
There are many image-file types that contain alpha channels (EPS, PNG, TIFF, TGA, PSD, AI, etc.), and a few video codecs that contain an alpha channel, like PNG, ProRes 4444, Animation, AVI, and certain Quicktime options. If you see the bit depth has a 32-bit option, then you can usually check a box or select the option to include an alpha channel.
Working with Alpha Channels and Mattes
Now that I’ve described roughly what’s going on, it’s time to move on to how to work with these types of items. The good news is, if you’re working with an item with an alpha channel, most of your work is done for you. You can really just import the file into your editing software (or VFX software), move it to the desired spot, and voila! Here’s another example of a clip with an alpha channel:
Cartoon Cheetah Running, Animation Cyclical by AlphaNature
When you start working with mattes, things get a little more tricky, but they’re still relatively simple to use.
The first thing you need to do is find an item with an alpha matte, which you can specifically choose in the advanced search on Pond5.
For my own composite, I’m going to use this glass breaking clip:
Cracked And Shattered Black Glass with Slow Motion by Arsgera
I’m putting it into my project(s), first with Premiere and then with After Effects, so you can see how it works with both.

Light Leaks, Explosions, and More: Creative Uses for Stock Media
Working in Premiere
Place the file in your canvas or drag it onto your timeline/sequence, and splice/edit the clip where the matte starts. Most clips are cut perfectly in half, so if the two halves don’t line up, check your edit point and try again. Place the matte (black-and-white section) on V1 (or V2, it’s not super important, and you’ll see why in a second), then place the “regular” footage on V3 or any higher layer than your alpha matte.
Now place your footage (or whatever you want to be revealed) under the “regular” clip, on V1 or V2. It can be above or below the matte, but it can’t be under the regular clip. Go to your effects panel and find the effect “Set Matte.” Place it on your regular clip on V3, then set the “Take Matte From Layer” to whichever layer has the matte on it (in this case, it’s V1).
Set the “Use for Matte” to “Luminance,” since it’s black and white, (or “grayscale”), then turn off the matte layer with the eyeball tool.
The reason you turn off the layer is because the effect just needs to use the clip’s information for the matte, and V1 doesn’t need to actually be visible.
Scrub through your timeline to make sure it works the way you want, and presto! Final result:
vimeo.com/video/186325208?&api=1&player_id=player665″ frameborder=”0″ webkitallowfullscreen=”” mozallowfullscreen=”” allowfullscreen=””/>
Working in After Effects
Drag your clip into your sequence, cut it at the correct moment, and place the alpha clip on layer 1, with the regular clip on layer 2. Then place your footage layer on layer 3.
Make sure your “Modes” column is visible, then on layer 2, click on the “TrkMat” dropdown. Select layer 1 as a “Luma Matte” (again, since it’s black and white), and you’re already done! Scrub through to make sure it looks the way you want, and you’re all set.
Getting a basic understanding of mattes and alpha channels is a great entry point into the world of compositing, which can open up many new ways to create. You can utilize these techniques to blend real footage and VFX together, helping to keep your projects fresh and interesting, while improving your skills.

Storm sewage
Storm sewerage is designed to collect and treat surface water and transport it to the main system, reservoirs or back to the water supply system for reuse.
The scale of the project, the list of constituent elements is determined individually, according to the wishes of the customer, budget and technical conditions.
KNS
KNS – complete pumping stations operating completely autonomously, can be designed to create a sewage system, a fire extinguishing system or reverse cleaning.Also, such a solution will increase the water pressure in the system with a weak pressure. The capacity of the complex can be up to 12,000 m3 / hour.
Tank equipment
Tank equipment includes fire, fuel, chemical and other tanks. They are made of fiberglass, so they do not corrode, do not emit toxic substances and have a long service life – several dozen are not.The volume, dimensions, the presence of additional layers and other parameters are selected taking into account the nature of the installation and technological requirements.
Domestic wastewater treatment
Domestic wastewater, both fecal and gray, from sinks, kitchens and bathtubs is easier and more efficient to clean and dispose of with our complete fiberglass system. The filtering elements are then cleaned of solid particles, ensure its disinfection, destroying all harmful microorganisms with the help of ultraviolet lamps.At the same time, the composition of the water remains safe, since chlorination is not used.
Industrial wastewater
It is difficult to dispose of industrial waste water, but this task is within the reach of the equipment
from Alfa-Composite. The multi-level system is designed taking into account the customer’s requirements, legislation and sanitary and hygienic standards. Cleaning is carried out from toxins, microorganisms and putrefactive bacteria, fats and products of oil refining, as well as solid suspension.The purchase and installation costs of the complex are minimal, and the filtration efficiency is very high.
Grease traps
Grease traps are filtration systems that allow you to purify wastewater from animal and vegetable fats, reducing their content to 50, and in some cases to 20 mg / l. Such indicators make it possible to discharge effluents from the main sewerage system or natural reservoirs. Grease traps have a high flow capacity, are easy to install and maintain, and have a long service life.
Wells
Wells are designed for maintenance and repair work, flow distribution, as well as for sampling wastewater. Fiberglass is used as the main material, which is not afraid of mechanical abrasion, exposure to an aggressive outdoor environment, and temperature extremes. Wells can be completed with a hatch, ladder and distribution inserts-trays.
Fiberglass roofing
The Alfa-Composite company has developed and launched into production an innovative and unparalleled in the world fiberglass roofing material “Adinol”.
Control cabinets
Automation systems, which complement the proposed complexes, allow making the functioning of the system completely autonomous. A modern, high-tech cabinet with diagnostic equipment will allow you to quickly respond to malfunctions. And the control elements will make it possible to centrally correct the operation of the system, turn on or off the pumps, and close the valves.

First of all, the septic tank “Crystal” is chosen because of its high degree of sewage treatment. As you know, anaerobic septic tanks do not fully cope with them, but only clean them by 30 percent. That is why the contaminated soil must be constantly removed so that the work of the anaerobic septic tank continues.
Whereas the degree of purification of VOCs “Crystal” from “Alpha-Composite” reaches 98 percent, which makes it possible to drain the industrial water obtained in this way into a rainstorm, use it for irrigating a garden or a backyard, and also release it into a nearby reservoir with the condition of preliminary use disinfectant.
Accordingly, the benefit in this case is quite understandable and obvious. Users of VOC “Crystal” from “Alfa-Composite” use the services of sewers only once a year, or even twice, which depends on year-round or seasonal residence on the site. And this leads to tangible material savings.
The service life of VOC Crystal from Alfa-Composite is at least 50 years, while an anaerobic septic tank lasts about 10 years. And the reason is that the Kristall body is made of high-quality, durable fiberglass, which is absolutely not afraid of external loads from the ground.That is why there is a separate guarantee for it.
In addition, users of the Kristall septic tank noted its ease of use. Each of them confirmed that the septic tank is not clogged, because its inlet and outlet reaches 110 mm. And also does not exude any unpleasant odors, which many anaerobic septic tanks “sin” for.
Undoubtedly, the cost of VOC “Kristall” can be called one of the main arguments in its favor, since at the moment it is extremely affordable when comparing prices at stations of this type.

python – Alpha Composite of an Image with OpenCV
I want to implement these steps:
Here is my code:
import cv2
from skimage.io import *
import numpy as np
imA = cv2.imread ('C.jpg')
kernel = np.ones ((3, 3), np.uint8)
imA = cv2.cvtColor (imA, cv2.COLOR_BGR2GRAY)
ret, mask = cv2.threshold (imA, 5, 255, cv2.THRESH_BINARY)
opening = cv2.morphologyEx (mask, cv2.MORPH_OPEN, kernel)
imshow (opening)
show ()
imF = cv2.imread ('157969651.jpg')
imF = cv2.cvtColor (imF, cv2.COLOR_BGR2RGBA)
imB = cv2.imread ('images.jpg')
imB = cv2.cvtColor (imB, cv2.COLOR_BGR2RGBA)
imF [:,:, 0] * = opening
imF [:,:, 1] * = opening
imF [:,:, 2] * = opening
imF [:,:, 3] * = opening
imB [:,:, 0] * = (1 - opening)
imB [:,:, 1] * = (1 - opening)
imB [:,:, 2] * = (1 - opening)
imB [:,:, 3] * = (1 - opening)
res = imF + imB
imshow (res)
show ()
Result:
I don’t know what is wrong with this code. Can anyone see what is wrong with my steps?

Alpha is not a channel, it is a mask.
My solution:
import cv2
import numpy as np
foreground = cv2.imread ('foreground.jpg')
background = cv2.imread ('background.jpg')
kernel = np.ones ((5, 5), np.uint8)
foreground_gray = cv2.cvtColor (foreground, cv2.COLOR_BGR2GRAY)
ret, mask = cv2.threshold (foreground_gray, 240, 255, cv2.THRESH_BINARY)
opening = cv2.morphologyEx (mask, cv2.MORPH_OPEN, kernel)
output = np.zeros (foreground.shape, dtype = foreground.dtype)
for i in range (3):
output [:,:, i] = background [:,:, i] * (opening / 255) + foreground [:,:, i] * (1-opening / 255)
cv2.
imshow ("img", output)
cv2.waitKey (0)
imshow ("img", output)
cv2.waitKey (0)
foreground.jpg
background.jpg
Output:

Check your mask in the range 0-1, not 0-255.

Review of the Crystal septic tank.
Advantages :
installation 1 day, customer support, clear consultations, the septic tank is strong and durable, works and filters very well, you don’t smell the smell
Disadvantages :
I did not notice anything like that for myself
My acquaintance with Alpha- Composite and a septic tank Crystal began last year, when I finally seriously planned to make an autonomous sewage system in my dacha.The construction of the house was completed and the question arose about the choice of a septic tank. Since I know very little about these things, I decided to seek professional advice. Alfa-Composite is far from the last company where I contacted, but I returned to them because they gave me clear explanations about septic tanks as to what would suit me, what would be better to take, and not just selling what was more expensive. Secondly, their prices turned out to be adequately lower than those of others.
Now about the septic tank itself. I immediately warned that I often go to the dacha with my mother (in the summer we stay there to live), and my children often visit, so it should be designed for at least 4 people.Plus, I needed something reliable, so as not to bother with cleaning, so that it would stand for a long time, since I was already spending such an amount.
Well, again, at a price not more than 100 thousand, it was just a ceiling. I was advised by Crystal 5. The septic tank is designed for a salvo discharge of 300 liters, and this, believe me, is a lot. Made, as I was told, of super-strong plastic, which is not afraid of impacts from the ground. And the Crystal has a peculiar shape, which further improves the stability of the septic tank after installation (well, that’s how I understood it).
Looking ahead, I will say that the septic tank has been in use for a little more than 4 months, I freely use the kitchen, bathroom, toilet, the septic tank filters all this, there have never been any blockages. They also assured me that there could not be any, since the inlet and outlet openings are about 11 cm, which is enough to prevent the same blockages. I will only note that I am careful with cleaning chemicals and do not use chlorine-containing products.
In order not to stretch my story at all, I will briefly tell you about the work of the company and installation.Initially, a measurer came to me, we discussed everything with him and agreed on the installation date for mid-June. On this day, the workers arrived early, dug, installed, set up all this miracle until evening. When we completed the check, we left. I still use it and not a single comment. I believe that Alfa-Composite has done an excellent job with the task.
I hope I got a review. I really tried to describe in as much detail as possible and wanted to express my gratitude to the firm itself.
