Animation is a hugely broad practice and has been around for many years. Fundamentally, animation is a method in which pictures are manipulated to appear as moving images.
Traditionally, animation involved images being drawn or painted by hand on transparent celluloid sheets. These were then photographed consecutively and made into a film. Now, most animations are made using Computer Generated Imagery (CGI). Stop-motion is also another animation technique for representing two and three-dimensional objects like puppets or clay figures.
At Polleni we commission animation from our network of trusted motion designers and digital animators, whose skill-set best reflect your brand. There are lots of different file formats we can use to represent this animation - broadly a 'file format' relates to how the data within an animation file is organised. A program that uses the data in a file must be able to recognise and possibly access data within the file.
Below is a glossary of some of the formats we work with.
- MP4: is a file format created by the Moving Picture Experts Group (MPEG) as a multimedia container format designed to store audiovisual data.
- MOV: is a multimedia container file format developed by Apple and compatible with both Macintosh and Windows platforms. It can contain multiple tracks that store different types of media data and is often used for saving movies and other video files.
- GIF: is an image encoded in Graphics Interchange Format (GIF) which contains a number of images or frames in a single file and is described by its own graphic control extension. The frames are presented in a specific order in order to convey animation. An animated GIF can loop endlessly or stop after a few sequences.
- Adobe After Effects: is a digital visual effects, motion graphics, and compositing application developed by Adobe Systems and used in the post-production process of film making and television production.It can be used for keying, tracking, compositing and animation.
- CSS (Cascading Style Sheets): make it possible to animate transitions from one CSS style configuration to another. We use these a lot in our Headless CMS websites. Essentially CSS animations consist of two components: a style describing the CSS animation and a set of keyframes that indicate the start and end states of the animation’s style, as well as possible intermediate waypoints.
We tend to lean to CSS animations on the websites we build, wherever possible. This is largely because:
- Letting the browser control the animation sequence lets the browser optimise performance and efficiency which ultimately leads to a better browsing experience. This can be done, for example, by reducing the update frequency of animations running in tabs that aren't currently visible.
