| Description | QuickTime File Format (QTFF) is a computer file format used natively by the QuickTime framework. The International Organization for Standardization approved the QuickTime file format as the basis of the MPEG-4 file format. Because both the QuickTime and MP4 container formats can use the same MPEG-4 formats, they are mostly interchangeable in a QuickTime-only environment. | OGV file is video file that uses the Xiph.Org's open source Ogg container format; may contain video streams that use one or more different codecs, such as Theora. Theora is a free lossy video compression format. It is distributed without licensing fees. |
| Technical details | The format specifies a multimedia container file that contains one or more tracks, each of which stores a particular type of data: audio, video, or text (e.g. for subtitles). Each track either contains a digitally-encoded media stream (using a specific format) or a data reference to the media stream located in another file. | The Theora video-compression format is essentially compatible with the VP3 video-compression format, consisting of a backward-compatible superset. Theora is a superset of VP3, and VP3 streams can be converted into Theora streams without recompression. |
