Hello I have some problem with PFtrack

When I import cmd file into houdini, all is ok but one problem, There is no animation curve for FOCAL LENGHT in camera, what is big problem. So I try import clip. There is all ok, but I need change some keyes on focal lenght at the and of animation. How I could do it in chops? Is there some possibility how to bake keyes ready for manual changes? There is little hip file. Please look at it. Thanks a lot….BC…
