Setting Image Generation Properties and Formats

Each of the image generating tools has a common UI area where properties can be applied.

The following table lists the common property controls and their function.

Property	Description
Format	Provides a selection of film formats.
Image Width/Height	Sets the width and height of the image produced by the generator node.
Image Aspect Ratio	Sets the image aspect ratio of the image produced by the generator mode.
Pixel Aspect Ratio	Sets the pixel aspect ratio of the image produced by the generator mode.
Rate	Sets the rate of the stream produced by the generator node.
Channels	Sets the number of channels of the images produced by the generator node. Possible channel combinations are: A RGB RGBA
Depth	Sets the depth per channel (in bits) of the images produced by the generator node. Possible image depths are: 8-bit 16-bit 32-bit
Repeat	Determines how the generator node outputs its result outside its source time range. Possible modes are: No Repeat: There is no repetition at all, the generator outputs black frames outside its time range. Hold: First and last frames are repeated. Loop: Repeats the entire sequence. Ping-Pong: Repeats the sequence from beginning to end, to beginning, and so on.
Mark in/Mark out	Defines the total number of frames the node generates for the image.
Start Time/End Time/Offset	Defines the time range (and any offset required) where the generator node is to output a result. It follows global time.
Lock Duration	Locks the Start/End time values.

NoteHeight and Width are animatable attributes—see Setting Keys Manually and Validating and Applying the Expression String.
