As we are all working on our rotoscoping projects using green screen, I wanted to give a little more information on what blue screen and green screen do and what they differ in.
The obvious reason for choosing one or the other is the object or person in front. So if you are filming Kermit, you probably don't want to use green screen and if you are filming a Smurf (they're real), you probably don't want a blue screen,
i found this video below to be super helpful in further understanding the difference and learning more about why we should use one or the other and when.
With talks of our third project, it has reminded me of some of my favourite YouTube videos. With a large viewer base, PistolShrimps have made quite a name for themselves through their "Harry Potter and the Outcasts of Hogwarts" series.
In these videos, the Pistol Shrimps duo appear alongside the cast of Harry Potter, in which they rework the meaning of many scenes. Edited together like a trailer, the two have green screened themselves into the well know films.
The first of their series
While the video above was clever, the actual placement looks alright. However in later videos, they really stepped up the quality, and quite convincingly put themselves into the world of Harry Potter.
One of their best Harry Potter videos
It seems the biggest improvement is in their lighting. I'd say they worked in a studio, and set up lights similar to what would've been used in the film. Lighting I think is one of the biggest keys to a successful chroma key, as it's extremely hard to mimic realistic shadows on a face in post. Here's a link to the full Harry Potter and the Outcasts of Hogwarts series.
Their latest video is also well worth a watch - some extremely talented compositing.
