Controlling video transcoder performance

 

When FotoWeb is licensed with the optional Audio/Video module it is possible to configure the allocation of system resources to transcoding operations using the Operations Center. This allows you to control resource allocation and the quality of the video proxy files that are used for playback. Note that the transcoder process priority is set below normal, so even if you have configured the transcoder module to use all your system resources, the transcoding process will not be prioritized by Windows if other processes claim much CPU power.

Where to configure transcoder options?

These settings are configured in the Operations Center:

  • Click on the FotoWeb node and choose ConfigurationOpen to open the FotoWeb server settings. 
  • Next go to the Service options tab and highlight the Advanced node. Transcoder options are listed in the Media files section.

Transcoder settings

Each configurable setting is presented together with the corresponding trade-off in the following table:

Settings

Action

Positive effect

Negative effect

CPU cores Many cores Fast transcoding May slow down your FotoWeb site and affect disk performance
  Few cores No effect on performance for the FotoWeb sites Slow transcoding
Quality High number Fast transcoding, small file size, low bandwidth required Degraded quality
  Low number High quality Slow transcoding, large file size, high bandwidth required
Compression speed Increase speed Fast transcoding Large file size, high bandwidth required
  Decrease speed Small file size, low bandwidth required Slow transcoding

License Restrictions

The optional Audio/Video module license is required for these settings to be applied. A maximum of 8 cores can be used for transcoding with this license.
