17-530: MXF or mxf may refer to: Material Exchange Format , a container format for professional digital video and audio media MXF, the IATA and FAA LID code for Maxwell Air Force Base , Alabama, United States mxf, the ISO 639-3 code for Malgbe language , Cameroon and Chad Topics referred to by the same term [REDACTED] This disambiguation page lists articles associated with
34-514: 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 . Other "Operational Patterns" can contain or reference multiple materials, just like a simple timeline of a video editing program. MXF has full timecode and metadata support and
51-423: A non-linear editing (NLE) system. The advantage of non-linear editing is the ability to edit scenes out of order, thereby making creative changes at will. This flexibility facilitates carefully shaping the film in a thoughtful, meaningful way for emotional effect. Once the production team is satisfied with the picture editing, the editing is said to be locked . At this point the turnover process begins, in which
68-408: A certain range of image editing operations to the raw image format provided by a photographer or an image bank. There is a range of proprietary and free and open-source software, running on a range of operating systems available to do this work. The first of post-production usually requires loading the raw images into the post-production software. If there is more than one image, and they belong to
85-496: A set, ideally post-producers try to equalize the images before loading them. After that, if necessary, the next step would be to cut the objects in the images with the Pen Tool for a perfect and clean cut. The next stage would be cleaning the image using tools such as the healing tool, clone tool, and patch tool. The next stages depend on what the client ordered. If it is a photo montage, the post-producers would usually start assembling
102-501: Is "mxf ", including a trailing space. This list represents some examples of free and open source products that support the MXF standard: SMPTE's top standards page has information, for the ordering of CD-ROMs, which would hold formal copy of the SMPTE standards. Judging by SMPTE's index, all of the standards, referenced above, would be contained on those CD-ROMs, as available from SMPTE . IRT Test Center contains up-to-date information on
119-489: Is a container format for professional digital video and audio media defined by a set of SMPTE standards. A typical example of its use is for delivering advertisements to TV stations and tapeless archiving of broadcast TV programs. It is also used as part of the Digital Cinema Package for delivering movies to commercial theaters. MXF, when used in the form of "Operational Pattern OP1A" or "OPAtom", can be used as
136-440: Is associated with a cold atmosphere. The choice of music and sound increases the effect of the scenes shown to the audience. In television, the phases of post-production include: editing, video editing, color correction, assembly, sound editing, re-recording, animation and visual effects insertions, combining separately edited audio and video tracks back together and delivery for broadcast. Professional post-producers usually apply
153-566: Is intended as a platform-agnostic stable standard for future professional video and audio applications. MXF was developed to carry a subset of the Advanced Authoring Format (AAF) data model, under a policy known as the Zero Divergence Directive (ZDD). This theoretically enables MXF/AAF workflows between non-linear editing (NLE) systems using AAF and cameras, servers, and other devices using MXF. From 2004 onwards, MXF
170-514: The MXF file extension. Without advanced tools, it was impossible to distinguish these incompatible formats. Some of the incompatibilities were addressed and ratified in the 2009 version of the standard. MXF is used as the audio and video packaging format for Digital Cinema Package (DCP). It is also used in the STANAG specification documents. The file extension for MXF files is ".mxf". The Macintosh File Type Code registered with Apple for MXF files
187-411: The complete editing, color correction, and the addition of music and sound. The process of editing a movie is also seen as the second directing, because through post-production it is possible to change the intention of the movie. Furthermore, through the use of color grading tools and the addition of music and sound, the atmosphere of the movie can be heavily influenced. For instance, a blue-tinted movie

#1732852529443204-502: The different images into the final document, and start to integrate the images with the background. In advertising, it usually requires assembling several images together in a photo composition. Types of work usually done: Techniques used in music post-production include comping (short for compositing, or compiling the best portions of multiple takes into a single composite take), timing and pitch correction (perhaps through beat quantization ), and adding effects . This process
221-585: The eVTR, Avid NLE systems, and broadcast servers using MXF in coordination with AAF are now possible. Long- GOP MPEG-2 material interchange between video servers is possible, as broadcasters develop application specifications they expect their vendors to implement. As of autumn 2005, there were major interoperability problems with MXF in broadcast post-production use. The two data-recording camera systems which produced MXF at that time, Sony 's XDCAM and Panasonic's DVCPRO P2 , produced mutually incompatible files due to opaque sub-format options obscured behind
238-450: The picture is prepared for lab and color finishing, and the sound is spotted and turned over to the composer and sound designers for sound design, composing, and sound mixing. Post-production consists of many different processes grouped under one name. These typically include: The post-production phase of creating a film usually takes longer than the actual shooting of the film. It can take several months to complete, because it includes
255-490: The status of the SMPTE documents. Post-production Post-production is part of the process of filmmaking , video production , audio production , and photography . Post-production includes all stages of production occurring after principal photography or recording individual program segments. The traditional first part of the post-production process, non-linear (analog) film editing, has mostly been replaced by digital or video editing software , which operates as

289-463: Was in the process of evolving from standard to deployment. The breadth of the standard was subject to lead to interoperability problems, as vendors implement different parts of the standard or interpret misleading parts of the standard differently. MXF is fairly effective at the interchange of D10 (IMX) material, mainly because of the success of the Sony eVTR and Sony's eVTR RDD to SMPTE. Workflows combining
