Green Screen Soliloquy

For this assignment we were shown 3 cameras; Black Magic, Canon & JVC which were available for us to use.

The Black Magic is a lovely camera, quite heavy but feels such a sturdy piece of equipment. Very streamline with only a few buttons and a fairly straightforward menu system to use. It is a digital film camera, it has a really wide dynamic range of 12 stops which will give you quality footage preserving the extreme highlights and lowlights. It also has three lens mounts, MFT, EF & PL which gives you a huge choice of lenses that can be used with it. The main downside is the size of the files, when shooting in native 4K Raw you will get every bit of data straight from the sensor or you can shoot in ProRes and get high quality video files and both will use up a massive amount of space.  So not only do you need a powerful SSD card you would also need a computer with enough power to process such large files so this was something I was concerned about for this assignment, but I would like to have a good play with it to see its potential at some point.

The Canon 650D is an 18 megapixel digital camera. It has a LCD touchscreen, it can shoot up to 1080p and has an EF/EF-s Lens mount. It was definitely the most easiest to use out of the three, setting the aperture, shutter speed and ISO was straightforward and once switching it to Video Mode and Manual, zooming in using the zoom button on the back of the camera to view the subject close up on the LCD screen so we were able to focus manually with the lens to get as accurate as we could the camera was set up to use.

So out of the two, depending on where your footage is destined for then the Canon 650d at  around £300 is definitely the cheaper easier to use option, the Black Magic costs just under £2000 so it’s a lot more expensive and is suited much for larger projects.

The JVC was actually the one that I was most wary of using because it is like nothing I have used before but once I was I got familiar with where everything was I quite liked it.

A fully digital interface provides all of the camera’s viewfinder indications: safety markers, focus assist, power and clip management.

In lessons Steve had shown us how to use the grid lighting this would be good for larger projects and if you were needing an even light across the floor as well as the backdrop. The grid has to be lowered to adjust the angle of the lights and move into different positions then raised and if its not right it has to be lowered and fixed. This was the reason i chose not to use it because it seemed more work than was necessary for lighting just one person and i planned to film from the waist up only so there was no need for floor lighting.

The ARRI floor lights were much easier to use and quick to move around to adjust the strength of light. It was important for us to be aware not to overload the (……..) and to only plug them in once they were all attached

WRITE SOME RESEARCH ON GREENSCREEN

We were given the chance to have a dry run at setting up our lights and camera and within my group we decided to use the JVC as this was what we were all looking to use. With Tasha as our actor we set up a 4 point lighting system with 2 ARRI 650’s on the green backdrop and 2 ARRI 300’s on Tasha one as the key and one as the fill and we played around with the distances of the lights until we were happy with the way she was lit and the backdrop was an even key as well.

On the day of my assessment i set everything up in a similar way to our dry run. I lit the backdrop with 2x ARRI 650’s, both at an equal distance from the backdrop, this set up gave me an even light all over the area behind where my actress Kamila would be standing.

The allyway clip i had chosen was a tight shot with the background gently out of focus and this was more suited for an up close shot so with this in mind i didn’t need to worry about having the floor lit to match the backdrop . Also the clip was quite dark with a few areas of light which showed a warm spill onto surrounding walls. So i decided to use an orange gel to create a similar warm glow on Kamila. I used this on the key light ARRI 300 which was closest to her and the other ARRI 300 was placed on the opposite side of her and a little further away to act as the fill light. It wasn’t even lighting in the clip so i tried to create this with my set up as it caused some shadow areas on her face.

I filmed her from 3 different distances so that i had some options to choose from in post and it turned out the closest version from the chest up was definitely the best in relation to the background.

Apart from struggling to get the battery out of the charging pack when i first started i didn’t encounter any issues and everything went to plan. When we did the dry run of this Tasha was stood in front of one of the seams on the backdrop and when we tried to key the background we found it hard to get rid of that line. Being aware of that i made sure that Kamila was nowhere near it.

Adobe Premier was my choice of editing software because i have used this previously editing our short films and am getting used to the basic controls. I was happy to see that i had lit the backdrop evenly enough to get a perfect key and didn’t need to get rid of any bad areas. There was a slight green tint to a few of the edge areas of her hair which could possibly of been avoided if i had used backlight to counteract the spill of green onto her hair.

Once i was happy with her size and position on top of the clip i adjusted the pedestal, brightness & contrast and tweaked the colour a little to balance her tones to the background. To remove the background hiss from her audio i used (denoise) and took it to 50% and this removed it.
