Shiny's Green Screen BEST
Filmmakers and videographers looking for an easy way to expand their shoots need to understand how to use green screens. With a good green screen, you can more easily create special effects, simulate locations, and build virtual sets. Green screen shoots can be inexpensive and there are plenty of software tools to help with keying out the green in post.
Shiny's Green Screen
In some situations, a green screen will be painted on a flat wall, but often green screens are hung using a green fabric material. In these instances especially, make sure to pull the screen tight on all sides.
This will help to eliminate shadows that your foreground elements might cast on the green screen. Just like creases and folds in the screen, shadows cast by the foreground elements will cause problems when you are trying to pull a clean key.
One of the easiest things to overlook when setting up shots for green screen is green reflections. Sometimes shiny objects or items like eyeglasses will pick up reflections of the green screen, which often get missed and are problematic later.
Shoot in at least 422, but most probably raw. Raw has a whole separate channel for the green screen, so you can avoid color contamination, or chroma sub-sampling that will mess up the edges of your key.
The most important aspect of keying is to ensure that the background screen can be easily separated from the foreground subject. You want your screen to be as different to your subject in color as possible.
Some digital cameras also have a tendency to retain more green data than blue, so if you are in a position to freely use either green or blue it is generally advisable to choose green. Blue screen was the best option for the optical keying processed used for handling film, but the different methods used for digital processing favor green. Either color is still capable of excellent results.
Green screen and blue screen photography has a few unique factors you will want to bear in mind while planning your shoot. Taking a little more time during setup to ensure everything is set up properly can save you a huge amount of time when you get on the computer, and ensure the best possible results.
A totally green background is not always facially friendly and can leave actors looking pale. Be sure to adjust your makeup to accommodate the lights and green screen background to avoid that washed out look.
Avoid any clothing that contains green tones of any kind, this is not limited to just the same shade as our green screen is painted but applies to all shades, even pastels or even green parts of a patterned material.
Also avoid wearing anything shiny or reflective, this applies to silk like or sequined materials, jewellery, and glossy belts or shoes. Glasses should also be removed where possible as the glass will reflect the green or the lighting in the studio
White shirts can cause issues with reflecting the green from the floor onto your cuffs and other parts of the shirt. Even when worn under a dark suit. A coloured or darker shirt such as blue or back will look much better on camera.

According to the IPCC's most recent report,4 the building sector is a relatively small contributor of greenhouse gas (GHG) emissions, releasing only 6.4% of all GHG direct emissions in 2010, but it was the largest end-consumer of total energy that year, being responsible for 32% of final energy use.5 Relatedly, the energy supply sector was the single biggest contributor of GHG direct emissions, releasing a quarter of all GHG direct emissions that year.
From Hollywood blockbusters to news broadcasting, green screens are a powerful tool every filmmaker should know how to use. Green screens allow filmmakers to separate a subject from the background in post-production. Once the filmmakers have taken out the background, they can replace the green screen with whatever footage they wish. For your next project, apply these practical green screen tips to take your production to the next level.
In post-production, a process called chroma key eliminates the solid green background from your subject. Chroma keying is a form of composting, a post-production term for editing in layers. Once you select the solid green color you are trying to key out, the subject and a transparent background remain.
Now you can add in a new layer of footage that will take the place of where the green screen once was. Make sure the subject layer (what you would like to see in the foreground) is above the background layer in the sequence. When done well, a proper chroma key can add substantial production value to your content.
Among green screen tips, this is the most important. If the green background is not a solid color, then the chroma key software will have difficulty distinguishing the darker greens from the lighter ones.
Do not wear green, as you will blend into the background, and the chroma key will make whatever green article of clothing you are wearing disappear. Have your subject wear colors on the other side of the color wheel to help avoid any potential mistakes.
If your subject is standing right in front of the green screen background, it will be impossible to keep the screen evenly lit behind your subject. Several feet of separation will allow you to place lights behind the subject to light your green screen background.
With several feet of separation between your subject and the green screen, if your subject is sharp in focus, then the green screen appears softer in the background. Soft focus smooths out the green screen to blend it into a more uniform color.
Blue screens also have less of a spill around the edges of your key than a green screen. Sometimes a hairline can be difficult to key out when using green screens due to this spill. Make a judgment of what color you believe will work best for your production.
You get the picture (or rather, the green screen!) Peerspace has similarly well-equipped and professionally managed studios in cities across North America and even across the pond. Spaces are easy to book and provide just what you need to one your craft.
The use of a green screen is more common than one would think, and these green screen tips demonstrate how using one is not too challenging. Green screens open up a whole new world of creative filmmaking, from VFX to allowing talent to perform driving scenes safely in a parked car. When you key out subjects properly, the viewer should never suspect there was a key in the first place.
And remember, if you a creator looking to test out these green screen tips in new surroundings, then check out Peerspace. We offer access to thousands of photo and film production studios fully equipped with green screens and other professional gear.
Video streaming is the most integral component of virtual conferences and I had a chance to take control of this aspect of the conference over two entire days, apart from the posters session that I will discuss separately. We used YouTube, and OBS for video compositing. I organized the content in advance for each day (Tuesday and Friday) in a linear fashion, where each scene represented a separate event or a possible transition screen. Not all scenes were used, since we often went directly from the welcome speech into the Keynote, but, nevertheless, I prepared additional scenes just to be sure. You can see a screenshot below.
Transitions between different scenes were done through the OBS studio mode which allows a few quick changes to be made before showing the scene on screen. Overall, that helped to fix some misalignments in the window capture cropping, so it is a very useful feature.
We relied on Zoom to arrange the actual callers and also for screen sharing presentations. Initially, we used maximized view of Zoom, but I had enough monitors in my setup to dedicate an entire monitor for Zoom (2 regular + 1 wide), so on Friday I actually used fullscreen Zoom. One thing to pay attention in OBS is that the regions might get moved in the prepared in advance scenes between application restarts. Fullscreen mode also allows you to have the chat and participants on a separate screen which leads to more optimal use of your monitor setup and greater video quality.
I made a very simple green screening setup at home. I had a Blue Yeti microphone attached on a boom arm which I kept just away enough from my face to easily remove it in post. The camera was mounted on Manfrotto 190 Aluminium 4 Section Tripod with Manfrotto 496RC2 Ball Head. I owned both for quite awhile and they served me really well and survived moves across three countries. I optimized their placement to allow me to use a long lens. I already owned a pretty big 65" Sony X800G TV which I used as a backlit green screen. One thing to keep in mind is that you might get some reflection of your key lights, so you want to place them in a way that avoids showing them on frame, i.e. the reflection is behind you or off-screen. To crop only the green screen part, I used a Laowa 60mm manual focus lens set at f/2.8. The video was shot at 1/60s exposure time and whatever ISO setting made sense depending on the illumination. My camera is a Nikon D7500 that I connect as a virtual camera using Sparkocam. In the future, I might consider spending some money on a proper video capture card or dongle because the virtual camera setup consumes way too much precious CPU time. I used a clicker and my laptop running PowerPoint as a teleprompter. Green screening and video editing was done in DaVinci Resolve, shown below.
On Wednesday, we had a short tutorial as part of the welcome session. Sheldon was streaming in this case and I did my tutorial by screen sharing a projected window in OBS. I had my keyboard and mouse input overlaid using NohBoard-ReWrite version 1.3.0 in window capture with chroma keying enabled. I used joao7yt / fps / outlined-black_normal-white layout for the mouse and keyboard. Below I show the entire setup. 041b061a72
