Quelle version de codec DnxHD pour quelle version de Sodt Avid ?
Depuis quelques temps les codecs DnxHD de Avid ont été mis à jour.
Vous trouverez ci dessous un point complet expliquant la compatibilité des diférentes versions codecs en fonction des différentes versions software Avid...
Q. What is the problem? What will happen if the codec is not updated? How will the problem manifest itself?
A. When VC-3 compliant DNxHD media is played in an Pre- Avid
Media Composer v4.x, Avid Symphony v4.x, Avid NewsCutter v8.x and Avid
DS v10.2 versions of the editor application, frames may be decompressed
incorrectly. This is characterized by only the top half of a frame
being decompressed with the bottom half of the image displaying either
black or green. Installing the updated codec in the earlier editor
applications, will result in correct decoding.
Q. What is Avid doing to fix this problem?
A. Avid will post codec updates for all older versions (Pre -
Avid Media Composer v4.x, Avid Symphony v4.x, Avid NewsCutter v8.x and
Avid DS v10.2) of the editors on the Avid Download center on September
25, 2009. At this time, we recommend that all customers update their
codec files to the latest version regardless of their workflow. The
individual downloads will contain information on the install procedures
for all released versions.
Q. What about customers using the new Avid Media Composer v4.x, Avid Symphony v4.x, Avid NewsCutter v8.x or Avid DS v10.2.x?
A. Avid Media Composer v4.x, Avid Symphony v4.x, Avid
NewsCutter v8.x and Avid DS v10.2.x software includes improvements to
Avid's DNxHD codec. The improvements were specifically implemented to
bring the codec into compliance with the SMPTE VC-3 specification.
These editor applications will decode any DNxHD media created by ANY
version of the editing application. No action is required.
Q. What about customers using any other version prior to Avid
Media Composer v4.x, Avid Symphony v4.x, Avid NewsCutter v8.x and Avid
DS v10.2.x:?
A. These editor applications WILL NOT be able to play back
media created with the new Avid Media Composer v4.x, Avid Symphony
v4.x, Avid NewsCutter v8.x or DS v10.2.x software. All earlier Avid
editor versions will require an updated codec if DNxHD media is used.
Below are the codec installers for previous verions of Avid editors
as far back as Avid Media Composer v2.2.x, Avid Symphony1.0.x, and Avid
NewsCutter 6.2.x. Please follow the installation instructions
carefully, which can be located in the corresponding ReadMe
If you are using Avid Xpress Pro or a version of Media Composer,
NewsCutter, or Symphony prior to the ones listed, and you have a need
to work with DNxHD media created in Media Composer 4.0, NewsCutter 8.0,
or Symphony 4.0 and higher, Avid recommends that you upgrade your
software to a version that supports the updated DNxHD codecs. For
information on upgrade paths, please visit our online store at http://store.avid.com or contact your local Avid Reseller or Avid Sales Office (http://www.avid.com/products/howtobuy/Index.aspx).
The Avid QuickTime Codecs have also been updated to support the new
DNxHD codecs. For more information on the QuickTime codecs, see the
