MemoryApplication 400
Working with 4K 12-bit Film
Even with the recommended amount of RAM, working with 4K 12-bit film puts great demands on memory
management. Set the RAM allocated for buffering frames to between 2000 and 4000.
The ability to mix different resolutions in a 4K 12-bit film project increases memory requirements even
further. Even with an override of the default memory management configuration, working at this resolution
may not support some advanced features that require a large amount of memory such as the Colour Warper
™
.
Cannot Allocate Memory Buffer Messages
“Cannot allocate memory buffer” messages indicate a shortage of memory allocated to frame buffering, so
uncommenting the MemoryApplication keyword and defining an amount of memory for frame buffers can
resolve this problem. The amount to set in this case depends on how much RAM your system has: start with
400 MB for Finishing applications or 700 MB for Visual Effects applications. Allocate more memory to frame
buffers in increments of 50 MB as required.
Memory Panic
A memory panic indicates the system is running out of heap memory. Heap memory is memory allocated
for use by applications and the operating system. Make sure no other applications are running. If memory
panic still occurs, lower the amount of memory allocated to frame buffers.
Remember that overriding the default memory management configuration is only required under these
specific conditions. If your system experiences problems related to memory management under normal
conditions, contact Customer Support.
Video
The Video keyword initialises the video device and specifies the video input type.
Video device The video input devices supported are AJA_OEMLH, and AJA_OEM2K.
Default video input format The default video input format that corresponds to the input configuration of
the video card. This setting is overridden by the video input formats specified by the lines you uncomment
for each VTR under the Vtr keyword heading.
The Video keyword uses the following syntax
Video <video_device>, <default_video_format>
Is:Where:
The video card used by your workstation. It can take the following values:
AJA_OEMLH for the AJA OEMLH card used in SD configurations on HP

AJA_OEM2K for the AJA OEM2K card used in HD/2K configurations on HP
platforms.
