A game's movie file: an ordinary ASF/WMV video whose first 12 header bytes were overwritten by the game's own wrapper (eight zero bytes and the whole file size), leaving every other ASF structure intact. Filestar restores the missing header bytes and converts the video.
An MP4 file is a multimedia file commonly used to store a movie or video clip, but may also contain subtitles or images. MP4 is short for MPEG-4 Part 14, which is a container format based on the QuickTime File Format (QTFF) used by .MOV and .QT files.
