FMP: Green Screen Tests (Break Free)

Green Screen Tests for Break Free

Photographed by  Chloe Lowe

These tests were to have a bit of fun and practice with the lighting. The difference between these tests and other that I have done before, is that we have used a green flooring as well, to allow more movement and create a wide shot that can be green screened. This really helps when you want your actor to be walking in a completely make belief world. I was watching a tutorial on YouTube about Matte Painting with people within a scene and gave it ago myself.

I have not posted the final outcome on here and posted them into the hand in folder instead. This was because I used a real claims number at the time but it was not made to be shown further than tests. Therefore, I would rather not post it on this post to be safe.

However, I can explain what I did to get to that stage. I have lost some of the tests I had done with the catwalk but I have placed the original footage in here anyway. I had done this for multiple tests, including the one with an actor jumping through a portal.

Firstly, I masked around the area where the actor moved so their whole body was always in the shot but the lights and other studio surroundings had been cut out.

I then used the key light as I usually do, and played with the setting so that the background was completely gone. Usually to get the best result, I change my view screen to matte black and white. Then I make the whole of the foreground white and background black to separate the image much more clearly.

Then I add in the background and any extra lighting where I think it works best. Followed by any graphics I want to add on.

Here are a couple of original clips. They do contain swearing. However, they did turn on well in the edit suite.

This portal test was done using the same green screen set up as above.

Professional Studies: How Does IMDb Work?

As part of my professional studies research, I have researched into how IMDB works and how to be credited for your own work for an online presence.

Firstly, IMDB stands for, Internet Movie Data Base, giving you the vague idea of what can be found within the website.You are able to find any creditable movie and much information about the movie you are looking for. As for non-commercial use, the website is free to use. To sign up a paid membership, you can use the IMDb Pro Website for a monthly price of $20 or if you pay annually, $12.50 ($149.99 a year). A registration in order to rate movies and write reviews is completely free.

Although any member is able to change and add information, similar to wikipedia, the website has consistent checks to ensure it has as accurate information as possible. If you add information to the website, it doesn't become public until staff has processed and checked the information given.The IMDb site claims that their source of information includes on screen credits, press kits, official bios, autobiographies, and interviews. 

Gods Among Us: Green Screening Research and Experiments (FMP)

Throughout my Minor Project, I began by researching further into the background of green-screening. Then also experimented with some green-screening. Since 'Gods Among Us' has some heavy CGI, I will be able to use the knowledge of green screening and key framing/animating movement as well as editing the main story.

Minimal Lighting Test with Green Screen

Minimal Lighting Test

This test included very little lighting. The idea was to see how bad the quality of the content is when you do not have good lighting. The image is even darker than the original because there is black video behind the image and it is seeking through all the particles in the video, due to bad quality of the lighting. When playing it back, the video has became extremely grainy.

The screen color needs to be as opposite to the persons skin colour and also balanced with light. Otherwise, it isn't going to work. Therefore, the screen needs to be lit so it is a bright green. However, you still need to be careful of over exposing it.

Too Much Lighting/Over Exposure

When taking out the green from the image, you can still see when too much light is hitting the back of the screen. This then becomes difficult to change the screen gain. To make the background you are about to place in look solid, the whole of the background behind the subject should be completely black in the image above. This is becomes a struggles because of the bad lighting.

When I take out more screen gain to reduce the background, the more the subject loses quality.

This is when I would add more screen balance so the subject is not merging into the background. In this image, I am losing too much of the subject and that will create the subject to become slightly transparent causing them to merge into the background.

Applying this to 'Gods Among Us' (Now Mercy)

Green screen was going to be needed for Gods Among Us to create an Egyptian setting.

Post Credits Animated Background

In my research, I have spent some time looking into particle effects. For a test, I decided to create a background that could be used for the credits on the children's project we are doing, currently by the name of 'Break Free' and toying with the name 'Beyond the Story'.

This is a creation using the particle effects in After Effects. By adjusting the psychics and producer, I was able to make the stars look like they were coming towards the screen, before adding in a camera that created a more 3D feel as if we are moving through the stars.

The colours were chosen to be pale, so they were not in your face but also they are very child like to suit the genre of the film.

I think it would be good if we are able to get a small animation of the unicorn, Taffy, from the film and play it within the credits.

Gods Among Us: Blue Screen Experiment Issues

I have been given some footage from the rest of my crew to test some blue screens. It was recorded on the black magic in the university film studio. In my experimentation, these are my main issues:

• Too much shadow casted on the actor as they move. Depends on what the background is like and where the light source is coming from but I wasn't given backgrounds to work with. I just found something from google images for test purposes only.

Image 2

• The actors arms have a lot of shadows but I am unsure if this is meant to be deliberate to work with the background. However, no backgrounds have been given, just foregrounds. With this being recorded from the Black Magic, I have enhanced a lot of colour. The photo shown above is just a before image. The blue was enhanced reasonably well without effecting the actor.

• As opposed to the above, another clip I tried to work with had better lighting on the actor than it did on the blue screen. This meant that it was really difficult to key out the background from the foreground. The blue wasn't bright enough and when enhanced, it also had an affect on the actor.

• In image 3 shows the clip mentioned in the above point. The background is far too dark. Image 4 shows when I attempted to enhance the colour.

• The colour on the actors face and body is changed a lot. I intend to experiment some more with the colour balance but it might help/take less time up if the lighting in the background was lit a little bit more.

My Castle VS Harry Potter Castle

Harry Potter images are found here

Hogwarts Castle Model

After looking at the Harry Potter castle, I imagine this would have had some painting added to it. Therefore, I thought I would look into it a little further. I found images on a newspaper article that shows the model of the Harry Potter exterior castle.

Philosophers Stone, CGI 

In the image to the right, this is what the model would look like once it was taken through post production. It would seem that the background, water and actors were added into this scene with the model of the castle

I attempted to do something inspired by this as one of my first attempts. Unfortunately, I lack the skills of making a model castle, therefore, I used stock images. However, this was filmed on Seaton Carew beach and changed later in post production. This was the best I could do on a make do attempt. It would still be effective in an actual film production.

Speed Paint of Digital Matte Paint (After Effects)

This is a speeded up recording of what I produced in After Effects. The final Paint.

1. Colour Correction

The main tools I used in this process are Masking, Colour Correction, 3D Layers and Lighting. I began by colour grading it and making it look a little less dull. In simple terms, I bumped the saturation up and changed the colour balance, masking around certain areas when, for example sand, needed changing separate to the rest.

2. Masking

A lot of this process included the same techniques of masking around individual images, In this video, the first time I begin to mask is on the first image I bring into the compostion. I depict a rock from the image and use the CC Toner in the colour correction selection to adjust the colour to match the rest of the image.

3. 3D Layers

I also spend a lot of time moving the masked images around the composition, as well as changind the size and orientation to manipulate the same image to look different as a fast and effective way of adding to the image. I also did this to all the shadows as well. I also spent a lot of time attempting to create shadows by doing this. To start with I was trying to do it with drop shadows but it wasn't working well so I made my own shadow by using the pen tool to create a shape, adding a directional blur it and turning down the opacity.

4. Lighting

Lighting was a new tool withing after effects that I used in this matte paint. I feel like this really helped to bring all the stock images look as if they are actually there. It was also nice to add in a sunset/rise feel.
