New Media Import and Export Features for DPX Files

• Upon import of a DPX file, the frame rate box now has an option called “file FCM” which will

detect and use any existing frame rate information in the DPX file to create the clip.

• Upon import of DPX, Wavefront, or Softimage images, the aspect ratio data is now read

correctly from the files.

• DPX files can now be exported as 12-bit clips.

• When exporting or publishing a DPX file, the application will now write “Autodesk” instead

of “Discreet” in the manufacturer field of the DPX file header.

• When you disable the Resize button during import/export operations, the aspect ratio of the

clip reverts to default.

• Background I/O now continues to completion even after you exit the application.

• Video clips can now be resized when exported in the Background.

DPX Transfer Characteristics

When exporting DPX files, you now have the option of choosing a DPX Transfer Characteristic

from the Transfer Characteristics option box. A DPX Transfer Characteristic is an information

flag that is stored in the DPX image file header. It identifies the attributes associated with a

particular film or video format, such as resolution, frame rate, and colour space.

Setting a Transfer Characteristic in no way changes the image information stored in the DPX

file. The Transfer Characteristic is simply a flag that is used to indicate the attributes of the DPX

file to another device or application. Some devices or applications may take advantage of this

information to improve workflow. For example, selecting Logarithmic can allow a film recorder

to adjust its parameters to print film-originated DPX files with the correct densities.

Although the SMPTE 268M standard defines a number of DPX Transfer Characteristics, it does

not provide usage specifications for them. As a result, most of these Transfer Characteristics are

not generally used in the industry. The table below explains the known and commonly used

Transfer Characteristics.
