Show highest quality player in Kaltura player

Hi, I tried to flashvar , mediaProxy.preferedFlavorBR=7000 and disableBitrateCookie=true , to load the Highest quality video present as default but this setting does not seem to be working and loading videos only at 360p as default. I am using Kaltura 12.13.0. I also tried different bitrate like 2000 and 70,000. But still not working.
