Has anyone used the Proxy editing feature in SVP 13.

I tried to, and am confused by the results.

Apparently the proxy feature should create smaller files, but from the attached image you'll see that it has created a file 3 x the size of the original at a higher (!!!) bitrate.
The play length has also doubled because the original was a 50fps video, and the proxy has reduced it to a 24fps rate.


There are no settings to alter the way the proxy creation works.

Has anyone any ideas what the problem might be??
