Our test with Adobe Premiere Elements 2.0 is performed with a raw two hour AVI file. It is then compressed into DivX format using the latest version codec. We measure the time it takes to encode and then record CPU usage.
Due to only 1GB of memory being available to the Reaper HPC kit, it falls down a little here as there is too much swap file usage with less than 2GB of memory for the encode process.
