Chroma is a player for movie files. It includes all necessary things like subtitle support, fullscreen play and playing DVDs.
Chroma supports most AVI formats like DivX/Xvid, QuickTime movies and online movies, and plays Windows Media, Matroska and Ogg Theora using standard QuickTime plug-ins. It supports most common subtitle formats, and uses the advanced text rendering in Mac OS X to render them. It presents DVDs in full scrub mode, can remove movie letterboxing and runs on all recent Macs.
