|The item proxying feature requires a dedicated license.|
Select the "Enable Network Proxy Caching option" checkbox for quick and safe rundown broadcasting. If this option is selected, only the most recent items will be played directly from the Cinegy Archive media server, and the rest of the rundown items will be played from the proxy server.
To set proxy configuration, you should:
Set the proxy folder path.
Set the proxy folder size limit.
|Leave at least 25% free space on volume for proxy to ensure stable work and smooth performance.|
The following settings are available here:
Proxy rendering preset – choose one of the following proxy rendering presets: Best performance, High quality or Uncompressed.
Read threads – define the number of proxy threads from 1 to 32.
Buffers – define the number of proxy buffers from 1 to 16.
The \"Throttle speed to <number>% of realtime" option is used to set the proxy speed limit. As a result CPU usage will be decreased by increasing proxy time.
|Please note that if the proxy speed does not exceed the defined limit, throttling will not work.|
The real time value depends on the current TV format frame rate. For example, PAL format frame rate is 25 fps. If you set the 1000% speed limit (250 fps) and the engine attempts to proxy the material at a speed over 250 fps, the time breaks will be added to the proxy process.
The minimal time of one chunk proxying for PAL format is:
100% of real time is 1000/25 = 40000 ms
200% of real time is 1000/50 = 20000 ms
A clip may contain media in three qualities: high, medium, and low. Only high media quality is used for proxying. If for some reason the high quality becomes unavailable, proxy files are not created for this clip. If the "Enable quality degradation" option is selected, the highest available quality (medium or low) of the clip will be proxied.
Press the "Reset to defaults" button to restore the default proxy settings.
To find out whether Cinegy Playout is playing the original media or its proxy copy, you can stamp the frames once they are rendered by creating a "StampProxyFrames" parameter with value set to "1" in the following Windows registry key:
if Instance 0 is used – HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Cinegy LLC\PlayOutEx
if Instance 1 is used – HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Cinegy LLC\PlayOutEx.1
Frames being read from the proxy folder are marked with color boxes:
