What is Stop Motion? Stop motion is an animated filmmaking technique in which objects are physically manipulated in small increments between individually photographed frames. When played in sequence, the objects appear to move independently. Dolls with movable joints or clay figures are often used because they are easy to reposition. Stop-motion animation using plasticine is called clay animation or claymation. However, stop motion isn't limited to figures or models. It can also involve humans, household items, or everyday objects—often used for comedic or creative effects. Sequential drawings can also be used, similar to traditional animation, like a flipbook. When stop motion involves human actors, it's referred to as pixilation or pixillated animation. Thanks for your support! Visit nitrio.com for more apps for your iOS devices.

 This app does not currently remove or key out green screens. It is a lighting tool created to help filmmakers properly illuminate their green screens for optimal chroma keying during post-production. Green screen removal is a planned feature for a future update, but it is not available in the current version. Please do not purchase this app expecting keying or background removal functionality at this time. Perfect Green Screen – Light It Right, Every Time Achieve flawless green screen lighting with ease. Perfect Green Screen is an essential tool for filmmakers aiming to master chroma keying by ensuring their green screens are lit to perfection. This app visually guides you through the process, helping you identify and correct uneven lighting using intuitive gray band overlays. Key Features: 1. Adjustable Precision
