Mirillis-Action, also known as Action!, is a video capture tool optimised for use by gamers. Designed and released by Mirillis Ltd, the software makes it quick and easy to share and upload gameplay videos to friends, social media and even to YouTube.

The program boasts sleek black graphics that gives even the most amateurish videos a slick professional finish, and is intuitively easy to use with a little practise. Among the facilities are the ability to capture and stream live action gaming, record music and sounds, capture and stream web player videos, capture screenshots and even remotely access the PC. The latter features also enables player to access their PC games through an Android device, ideal for bored moments when out and about, away from the computer desk. Captured screenshots are saved as .jpg files to make them easier to share.

Videos can be enhanced with the addition of music or a personalised commentary using the PC's microphone. These sounds can be easily integrated into the video footage to create a complete and professional-looking piece of video. It is even possible to add-in slow motion highlights for dramatic or humorous effect.

The record facility is excellent, and capture continues, even if the player switches between screens or programs briefly, ensuring that every action-packed moment or high score is preserved for posterity.

Video capture can be translated to a multitude of formats, so that the video can be screened on a range of platforms and devices. Each piece of footage can be compressed for ease of transfer, unpacking smoothly and seamlessly once it has been uploaded or sent to a new viewer. Mirillis-Action not only optimises speed of transfer, it also uses power in an ergonomic and efficient way so as to not abuse resources.

The video captured can be, if the equipment is so geared, in full HD, up to and including 4K Ultra HD.

There are three different capture modes: Game, Desktop and Fragment, which are selectable with one click. Other settings such as video duration, frames per second and the size of the video amongst others (some optional, others mandatory) can then be chosen to customise the video to the desired specifications. Once the video recording is complete it, and the other recording that have been made, are visible on the left-hand side of the interface so they can easily be selected and sent to social media or uploaded to YouTube or other video channels.
