Cutting bvh Files

Hi Guys,

Is there a way to actually cut bvh Files in Blender?
I got a 7000frame long animation with several movement, that I want to reduce to a specific frame area, because exporting as an fbx file simply takes too long.

so is there a way to simply delete all of the unneeded frames in order to just have a bvh animation that is 30frames long, which would also reduce the size of my file?
