UM:Application Preferences Rendering
The Rendering preference tab configures global settings used as defaults for various render parameters.
DPX Export Style
The default DPX image format used for DPX exports.
Values : |
Big endian, Little endian |
Default : |
Big endian |
• | Big endian ("cineon" format) |
• | Little endian ("OpenGL" format) |
A big endian DPX file has header magic SDPX (ascii). A little endian DPX file has header magic XPDS (ascii). This specifies the byte-order used in the file and has an impact on DPX compatibility. The default should be most compatible. |
DPX Export Colour Depth
This specifies the default bit depth and colour data format for exported DPX image files.
• | Current colour depth RGB - default. This sets the export bit-depth per channel as per the current output format, and uses RGB colour space. |
• | 12 bit RGB - use 12 bits per channel, RGB. |
• | 10 bit YUV - use 10 bits per channel, YUV. |
Render Tile/Frame Threads
These settings control how many frames we try to render in parallel, and how each frame may be split for further concurrency in the render process.
• | Render tile threads - this defines how each individual frame is split (tiled) for rendering in parallel across multiple CPU cores |
• | Render frame threads - this defines how many whole frames are rendered in parallel. |
These settings are dependent on the system type. See the Install and Configuration Guide for configuration settings for various supported systems. |
Image Memory
This setting defines a "pool" of memory the application will allocate for storing and rendering image sequences.
Cache Rendering Setup
These parameters setup some options on how cache renders are generated.
Cache preallocation frames
Values : |
text entry |
Default : |
20 |
This defines how many frames are preallocated for caches before the caches themselves are written to disk. This will help prevent caches getting fragmented.
Cache fragmentation test
Default : |
on |
If turned off, caches will not be tested for fragmentation and no fragmentation status will be displayed on the timeline.
