| − | __TOC__
| |
| − | === Compatibility with Previous Releases ===
| |
| − |
| |
| − | Projects and notes from previous releases (starting with release 2012.1) are compatible and supported in the latest version.
| |
| − |
| |
| − | {{M-Note|To use older projects (or notes), copy them into the appropriate project (or notes) folder.}}
| |
| − |
| |
| − | {{M-Alert|Projects and notes from the current release are not compatible in previous versions. Once opened in the latest release, you should not open a project in any older release (even the last) or project damage might result.}}
| |
| − |
| |
| − | === Memory Settings ===
| |
| − |
| |
| − | This release is 64 bit and can take advantage of all available memory on the system.
| |
| − |
| |
| − | Application memory usage is controlled using the preference setting <tt>memoryImagePoolMaxMB</tt> (in megabytes). New installations will set this parameter to TOTAL RAM - 6 GB by default but you may want to change this. You can change this through editing the preference file or in the GUI Preferences / Rendering : Image memory :
| |
| − |
| |
| − | {| width="40%" cellpadding="4" border="1" style="border-collapse: collapse;"
| |
| − | |- style="background-color: #dedede;"
| |
| − | |'''Parameter'''
| |
| − | |'''Default'''
| |
| − | |'''Alternative'''
| |
| − | |-
| |
| − | |<tt>memoryImagePoolMaxMB</tt>
| |
| − | |RAM - 6 GB
| |
| − | |RAM - 4 GB
| |
| − | |}
| |
| − |
| |
| − | Examples :
| |
| − |
| |
| − | {| width="40%" cellpadding="4" border="1" style="border-collapse: collapse;"
| |
| − | |- style="background-color: #dedede;"
| |
| − | |'''RAM'''

| |
| − | |}
| |
| − |
| |
| − | {{M-Note|You may need to experiment to determine best settings for your workload. Note that this discussion assumes no other application is running at the same time as ours. In particular, any external helper applications such as ''Apple Quicktime'' or ''Avid'' will also allocate and require their own memory areas. }}
| |
| − |
| |
| − | === Thread Settings ===
| |
| − |
| |
| − | There are two ''thread'' preference settings available. The recommended settings are :
| |
| − |
| |
| − | {| width="50%" cellpadding="4" border="1" style="border-collapse: collapse;"
| |
| − | |- style="background-color: #dedede;"
| |
| − | |'''Parameter'''
| |
| − | |'''Value'''
| |
| − | |-
| |
| − | |<tt>renderFrameThreads</tt>
| |
| − | |Number of CPU Cores (see below)
| |
| − | |-
| |
| − | |<tt>renderTileThreads</tt>
| |
| − | |1
| |
| − | |}
| |
| − |
| |
| − | These recommendations are set automatically on fresh new installs of the latest version where a preference file does not exist. If the preferences exist, the settings inside will be used. '''It is best to let the application create a brand new preference file by moving any existing one out of the way.'''
| |
| − |
| |
| − | The <tt>renderFrameThreads</tt> and <tt>renderTileThreads</tt> parameters are available in the preference file and via the GUI Preferences / Rendering section.
| |
| − |
| |
| − | {{M-Note|If the application starts running out of memory for rendering, one way to mitigate this is to try reducing the number of ''Frame'' threads.}}
| |
| − |
| |
| − | ==== Optimising Performance and Threading ====
| |
| − |
| |
| − | These thread settings may not be optimal for your specific workflow. For best performance, you should analyse and benchmark your workflow using a variety of thread settings and select the settings that work best for you.
| |
| − |
| |
| − | {{M-Note|Optimising threads can have a big impact on render speed so it is a good idea to undertake some tests before starting a job.}}
| |
| − |
| |
| − | {{M-Note|To determine the number of cores and an optimal value for <tt>renderFrameThreads</tt>, see the [[:Support:FAQ#cores|FAQ]].}}
| |
| − |
| |
| − | === DPX Compatibility ===
| |
| − |
| |
| − | There are some DPX specific compatibility settings you can add to the <tt>Clip.prefs</tt> file (in your [[Support:FAQ#rootfolder|ROOT]] folder) :
| |
| − | <pre>
| |
| − | DPX
| |
| − | {
| |
| − | luma10PadLines BOOLEAN
| |
| − | luma10MSBFirst BOOLEAN
| |
| − | RGB12as2011 BOOLEAN
| |
| − | }
| |
| − | </pre>
| |
| − | Where BOOLEAN can be "true" or "false" (without the quotes).
| |
| − |
| |
| − | {| width="70%" cellpadding="4" border="1" style="border-collapse: collapse;"
| |
| − | |- style="background-color: #dedede;"
| |
| − | |'''Parameter'''
| |
| − | |'''Note'''
| |
| − | |'''Default'''
| |
| − | |- style="vertical-align:top;"
| |
| − | |<tt>RGB12as2011</tt>
| |
| − | |Compatibility mode for 12 bit packed RGB DPX images. If set to "true", uses previous mechanism for creating these files (2011 and earlier).
| |
| − | |false
| |
| − | |- style="vertical-align:top;"
| |
| − | |<tt>luma10PadLines</tt>
| |
| − | |10 bit luma packing mode. If set to "true", pack luma scan lines to 32 bit boundaries.
| |
| − | |true
| |
| − | |- style="vertical-align:top;"
| |
| − | |<tt>luma10MSBFirst</tt>
| |
| − | |10 but luma packing style. Id set to "true", first pixel if placed in MSB (most significant bit) of the 32 bit word.
| |
| − | |false
| |
| − | |}
| |
| − |
| |
| − | {{M-Note|'''Compatibility with 2011.2'''
| |
| − |
| |
| − | For complete compatibility with version 2011.2 and earlier, you should set :
| |
| − | <pre>
| |
| − | DPX
| |
| − | {
| |
| − | luma10PadLines false
| |
| − | luma10MSBFirst true
| |
| − | RGB12as2011 true
| |
| − | }</pre>
