A video file format is a type of file format for storing digital video data on a computer system. Video is almost always stored using lossy compression to reduce the file size. A video file normally consists of a container (e.g. in the Matroska format) containing visual (video without audio) data in a video coding format (e.g. VP9 ) alongside ...
Raw MPEG-4 Visual bitstreams are named .m4v but this extension is also sometimes used for video in MP4 container format [21] or in the M4V container format. Mobile phones used to use 3GP , an implementation of MPEG-4 Part 12 (a.k.a. MPEG-4/JPEG2000 ISO Base Media file format), similar to MP4.

Each 10-minute episode starts with a logo of the studio (Soyuzmultfilm in episodes 1-18, Studio 13 in episodes 17 and 18, and Christmas Films in episodes 19 and 20), after which a prologue begins. The prologue is a separate short story, approximately 2 minutes long, at the end of which the Wolf shouts "Well, [rabbit], just you wait!".
A video coding format [a] (or sometimes video compression format) is a content representation format of digital video content, such as in a data file or bitstream. It typically uses a standardized video compression algorithm, most commonly based on discrete cosine transform (DCT) coding and motion compensation .
MPEG-4 Part 17, or MPEG-4 Timed Text (MP4TT), or MPEG-4 Streaming text format is the text-based subtitle format for MPEG-4, published as ISO/IEC 14496-17 in 2006.
