Foreword
Alhamdulillahirobbilalamin, all praise be to Allah Lord of the Universe for all the blessings, grace, Taufik, and His guidance so that I can complete the task with the title "How to Make Green Screen Tutorial - Chroma Key Backgrounds Movie Effects Change".
In the preparation of this task, the author gained a lot of support from other parties. I would like to thank Mr. HENRY P, IR, MM, M. Kom, as the professor who has provided guidance and direction so that I can accomplish this task, and both parents, my extended family, and fellow students who STMIK AMIKOM YOGYAKARTA always pray and give me motivation.
I realize that this task there are still many shortcomings. Therefore, I expect criticism and constructive suggestions that this task can be even better. Final words I hope the terms of reference of this task can provide insight and knowledge to the common reader and the writer in particular,
Description of Duties
Green screen is a great addition to video production. Film of the green screen provides the ability to film was shot in a room outside the room, and replace the background with any outside elements that want to do during the final editing process. Film scenes hiking in the living room, and replace the background with Mount Everest later
Instructions
What you need
1.Greencloth
2.PVC pipe
3.Drill
4.4 bungee cords or strong rubber bands
1. Buy you a green screen material. Ensure that all types of non-reflective green material, felt, feathers or even kapasakan work. Buy a larger size, 10 feet should be plenty.
2. piece your desired fabric. Clean up a large space in the room filming and clear it of debris all. Measure the space before cutting your green screen material. Cut the material for the measurement of filming the room cleaned you.
3.fabric shops to the wall cloth if you plan to shoot in space at any time. If you need a portable green screen, building frames.
4.buy pipes PVC from your local stores. Purchase enough to make your frame slightly larger than your green screen material is cut. If your material is 4 feet by 6 feet, you need a 5-foot by 7-foot frame.
5.piece hole in your fabric of each leg. Borlubang in your PVC to match it, and then loop material for pipe loop with bungee cords or strong rubber bands.
Process
The process of making a video or image using the chroma key technique is the subject to be photographed standing in front of the background with one color, or a bit of color composition. Commonly used color is green or blue because these colors are considered at least kulit.Porsi color resembles the color green or blue in the background belakangakan replaced with another image. This process is known as keying, keying out, or just key.
Currently the most commonly used color green than other colors, for receiving the image sensor in a digital video camera is the most sensitive to green color. This is consistent with Bayer Pattern that allocates more pixels kesaluran green, mimicking the human eye sensitivity is increased terhadapc ahayahijau.Oleh therefore, the green camera channel experience less interference and produces the most jernih.Tambahan key again, the less light needed to illuminate green color, green color due to the sensitivity of the sensor image over the bright green tinggi.Warna also favored because the bias so the blue background color to resemble the subject's eyes or clothing.
The blue color was used before the widespread use of digital keying, because blue is required for the optical process, but requires more radiation than the color green. Nevertheless, the blue color has the advantage that in the visual spectrum, the color blue more than red, which is the main color of the skin manusia.Faktor most important key is the separation between the foreground color (the subject) with a background color (the screen). The blue screen will be used if the primary color of green dalah subjeka (eg if the subject of a plant), although the camera is more sensitive to green color.
In the analog color television, color is represented by the phase of the chroma subcarrier relative to osilatorrujukan.Kunci chroma is generated by comparing the phase of the video denganfase corresponding with the previously selected color. Video portion is replaced with another video in the background.
Digital television in color, the image is represented by three numbers (red, green, blue). Chroma key is generated by a simple numerical comparison between the video with the previous color selected colors on the screen corresponding suatutempat (exactly, or the like), then the video in place will be replaced with another background video.
Clothing
Chroma key subject must not wear clothing with colors that resemble the color of the chroma key (warnalatar), because the color of clothes can be replaced with a video background, unless deliberate demikian.Contoh deliberate use is when the actor wearing a green or blue bodies to make it visible in the final shot. This technique can be used to produce an effect similar to the effects of invisibility cloak that used in the movie Harry Potter. The actor can also be recorded against the background of the chroma key and background shot put with a distortion effect with the aim of creating a garment that can be detected fine. The problem arises when the costumes used to be colored blue and hijau.Misalnya, in Spider-Man movie in 2002, the scene where Spider-Mandan fight in the air Green Goblin, Spider-man should be recorded in front of a green screen for ya kostumn blue and red. While the Green Goblin should be recorded on a blue screen, because the fully-colored costumes worn hijau.Jika depanlayar both recorded at the same time, makasalah one character is removed from the shot.
Background
The blue color is generally used for weather maps and special effects, because these colors to complement with manusia.Penggunaan color blue is also related to the fact that the film emulsion layer has a crystal blue of the purest and therefore has good detail and minimal grain, compared with emulsion color red and green. However, in the digital world, the color green to the color of your favorite digital cameras for storing more detail in the green channel, green danwarna also need less light than the color biru.Hijau not only has a higher value than blue light, but also in the initial digital format, the green channel as an example two times more frequently than the blue channel, green is more familiar to use. Actual choice of color depends on the artist effects (effects artist) and kebutuhanakan particular shot. In the past decade, the use of green to be dominant in movie special effects. Green background is also preferable from the blue when filming done in the open, because the blue sky into the frame bias and inadvertently replaced participate in the chroma key process.
Although green and blue is the color commonly used, but in fact almost all the color magenta screens used digunakan.Adakalanya bias, magenta or fuschia nilaiwarna called a magic pink key.
Along with improved pictures and equipment, many companies avoid the confusion that is often experienced by weather presenters cuaca.Dahulu presenter should watch yourself on the monitor to melihatgambar shown behind them, kinigambar projected kelayar thin green / blue. It inimembuat the presenter is able to accurately indicate a place and look at the map without having looked at the monitor.
Newer technique is to use curtains retroreflektif (retrore flective curtain), in the background, along with circular LED (Light Emitting Diode) that light around the lens kamera.Dengan this way, there should be no light to illuminate the background, in addition to the LED just need a bit of power and place, not like a big stage lights. In addition it also does not require rigging LED (light mounting). Possible by advances in the practical temukannya blue LED in the 1990's. The same goes for emerald green LED.
There is also bentukcolor keying using invisible light spectrum of people, called Thermo-Key key.Thermo using infra red as its color key, which can not be replaced by the background image post-processing.
Conclusion
Green screen is a great addition to video production. Film of the green screen provides the ability to film was shot in a room outside the room, and replace the background with any outside elements that want to do during the final editing process
Suggestion
Quite well in because of the color green has become a favorite color.
Cover
Thus we can describe the material that becomes subject to this task, of course, still many shortcomings and weaknesses, because of the limited knowledge and lack of referral or reference that has to do with this job title.
I much hope that the reader can provide constructive criticism and suggestions to me for this job perfectly and the writing task at the opportunity - the next opportunity.
This task may be useful for me in particular, also the general reader.
