svg SVG or Scalable Vector Graphic File is a graphical format for images which are bi-dimensional and XML-based providing support to animations and various interactive elements. The SVG file format was developed with the open standards created in 1999 by the W3C (Worldwide Web Consortium). Adobe Corporation held the significant role towards the development of this file format, and it is considered to be the industry standard for viewing vector graphics on web networks. SVG images can be created, edited, and recreated in any of the text editing tools and drawing or illustration software. Additionally, SVG can be compressed, searched, scripted, and indexed.
mtv The .mtv filename extension is the second filename extension that refers to the proprietary video file format container AMV. AMV is a video container modified from the AVI video format and is primarily associated with video enabled Chinese portable MP4 players. Video stream files with either the .amv or .mtv filename extension can be played back on these devices. To maintain a relatively low cost, these MP4/MTV players rely on this video format and inexpensive hardware rather than more common but expensive proprietary video playback formats.
