Reference Black and Reference White. Leave disabled when the deliverable is broadcast, and enabled when
you want to provide wider range for post-production processes like grading and visual effects work.
Automatically disabled when exporting using a QuickTime RGB codecs.
YUV Encoding box Select the clip's YUV colour space. The application uses this to translate native RGB
values into YUV ones. Use Auto to assign a colour space based on the resolution of the output clip: Rec.601
for clips smaller than HD, Rec.709 for HD and larger.
Smoke works in the RGB colour space: it needs to translate RGB information back into YUV. This setting
ensures that the right encoder is used for this. The Auto setting selects the colour encoder based on the
resolution of the clip: Rec. 601 for clips with a resolution lower than 720 lines, Rec. 709 for everything else.
Specifying the wrong colour space results in colours that are off. Per Recommendation BT. 2020, UHD media
should use the Rec. 2020 colour space. But this is rarely the case at the moment: UHD clips still use Rec.
709. The Rec. 2020 option is there is case you need the new standard.
Filename field Displays the result of the pattern displayed in the Filename Pattern field. Non-editable.
Filename Pattern field Displays how to name the exported media files. Build a dynamic naming scheme
using Add Token and characters normally allowed in a file name. Create folder structure using / . The file
extension is automatically appended. Add '#' to numerical tokens to define padding. Editable.
Add Token box Inserts a token in the Pattern field to build a dynamic filename.
Include Audio button Enable to include audio tracks within the exported file. Available only if Export
Type set to Movie.
Video Options tab
Video Format field Select the format for the exported media.
Compression box Select the image compression to apply to the exported file sequence. The available
compressions depend on the selected Video Format.
Link Original Media button Enable to hard link the published files to the original files if both the original
and exported files are located on the same filesystem. If not, the application creates soft links back to the
originals. Available for file sequences only.
This option saves disk space on export as files that remain unchanged by the export are not duplicated.
Unchanged in this context means they were not rendered not resized in anyway. For example, a file sequence
of 20 dpx are imported in Smoke. Of those 20, 12 are modified in some fashion. With Link Original Media
enabled, of the sequence of 20 dpx, only the modified 12 are actually created at export; the other 8 dpx are
just linked to from the export folder.
This option can be used even when the colour space of the timeline is different from that of the frames, for
example, when promoting 16-bit integer DPX files to a floating-point timeline (see
Converting Images
Between 12i or 16i and 16f Encodings
(page 1319)). Any frames that have a colour transform assigned in the
import settings, as well as the corresponding inverse colour transform assigned in the export settings, will
be linked if those frames are otherwise unchanged. If you are creating your own .ctf files, note that the
inverseOf attribute of the export transform must be properly set (see
ProcessList (page 1328)). Any frames that
do not have the inverse colour transforms applied on export are processed as usual.
DPX Transfer Characteristics box Select an option to identify the attributes associated with a particular
film or video format, such as resolution, frame rate, or colour space. Available when Video Format is set to
DPX.
When exporting DPX files, you can choose a DPX Transfer Characteristic. A DPX Transfer Characteristic is
information 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.
Setting a Transfer Characteristic in no way changes the image information stored in the DPX file. The Transfer
Characteristic simply indicates the attributes of the DPX file read by another device or application. Some
