If I import a chan file with baked camera data for every frame and if I export the cahnnels inside Houdini to the camera the keyframes in the file do not match to the frames in Houdini. My timeline goes from 0 to 149 but the values on frame 149 in Houdini corresponds to a value between 144 and 145 in the chan file. How can I fix that? Unfortunately it's not only a shift and a resample does brake the exact values.

Found it. Override the sample rate with $FPS and a strech afterwards.
