24 Chapter 2 Using the Xsan Tuner Application
Understanding Final Cut Pro Test Results
The Final Cut Pro Read and Final Cut Pro Write tests performed by Xsan Tuner compare
the data rates possible through a specific Final Cut Pro codec against the throughput
needed to stream that data without dropping frames.
A frame drop message, shown below, indicates that the required throughput can’t be
sustained by the SAN in its current configuration:
Adjusting the Result for Audio Streams
Because the video streams generated by the Xsan Tuner Final Cut Pro read and write
tests do not include audio content, you should adjust the test results downward if your
clients will be working with audio.
If the client computer you are testing will be processing both audio and video, subtract
one stream from the Xsan Tuner results to estimate how many video streams can be
supported.
For example, if Xsan Tuner shows that the SAN can support four video streams for a
client, the actual number of sustainable streams is more likely to be three if the streams
include audio.
The white line marks the
minimum required data rate
for the specified streams.
