The number of transforms and transforms_smooth is 2 less than the total number of frames.

for(int i = 1; i < n_frames-1; i++)

When writing out the frames, the loop is using n_frames as the count, so accessing transforms_smooth[i] will overrun the array when i == n_frames - 2.

for( int i = 0; i < n_frames-1; i++) { ... transforms_smooth[i].getTransform(T);
