Forms Data Format is defined in the PDF specification (since PDF 1.2). The Forms Data Format can be used when submitting form data to a ...
An XDP can also package a PDF file, along with XML form and template data. [3] When the XFA (XML Forms Architecture) grammars used for an XFA form are moved from one application to another, they must be packaged as an XML Data Package. [2] The format of an XFA resource in PDF is described by the XML Data Package Specification. [4]
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 ...
Adobe Systems introduced the F4V file format for Flash Video in 2007 and said it is based on the ISO base media file format.

Sharable Content Object Reference Model (SCORM) is a collection of standards and specifications for web-based electronic educational technology (also called e-learning).

MXF, when used in the form of "Operational Pattern OP1A" or "OPAtom", can be used as a container, wrapper or reference file format which supports a number of different streams of coded "essence", encoded in any of a variety of video and audio compression formats, together with a metadata wrapper which describes the material contained within the MXF file.
M2TS supports Digital 3D as multiple files in a specific file structure for encoding stereoscopic video: MVC stereoscopic data is in .ssif files in the /BDMV/STREAM/SSIF/ directory and require a respective base .m2ts file. Digital 3D in QTFF and ASF is possible, but not standard. MP4 only supports Digital 3D at the video format level. [44]
