Aspect Ratio field Enter the aspect ratio of the imported frames, as a Width:Height ratio. Enabled when the
Aspect Ratio box is set to Enter Aspect Ratio or Square Pixels.
YUV Decoding box Select the YUV colour space used by the clip to import. Because Smoke works in the
RGB colour space, it needs to translate YUV information into RGB. This setting ensures that the right decoder
is used for this. The Auto setting selects the colour decoder 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 use Rec. 709. The Rec. 2020 option is there is case you come upon a correctly
encoded UHD clip.
Include YUV Headroom button Enable to keep the YUV headroom information during clip import. Disabling
this option for clips that use the headroom (usually clips from cameras) results in clips with clamped black
and whites. Enabling this option for clips that do not use the headroom (usually clips from Final Cut Pro)
results in an imported clip with lowered contrast.
Scale to Full HD button Enable to have media with a 1280x1080 or 1440x1080 resolution display at a
standard 1920x1080 resolution. Disable to display the media at its native (1280x1080 or 1440x1080)
resolution.
Open Clip Format Settings - Import
Although there are no import options for an Open Clip, the media it references is still imported using that
media's Format Specific Options: a referenced .mov is imported using QuickTime settings, while a referenced
.dpx sequence is imported using DPX settings.
Working With Open Clip Files
About Open Clip Files
In its simplest form, an Open Clip file consists of two parts:
A .clip file
Media files
The media is any supported media files, from DPX sequences to RED files, including multi-channel OpenEXR
renders. The other component, the .clip file, is written in the XML format; you can open a .clip in any word
processor (kedit, notepad, TextEdit) and decipher its content.
In essence, the .clip file contains all the metadata and references to media that are required to define a source
and its versions. The .clip file does nothing by itself, but is essential to recreate the sources, similar to how
a wrapper works, whereas a source is similar to the essence of a P2 clip.
One of the strengths of the open .clip is that anyone can create .clip files. With one, you can manage media
outside of the Smoke application.
Using an Open Clip file, you can define many aspects of a clip, including:
Source information
Versioning
Multiple channels of media
Paths to media
