@ JulzMighty:

The way I visualized what Phemox was talking about was refering to hardcoding each cutscene specificly, meaning in functions setting each property individually, like a line by line script execution. Therefore, what your doing lies at the other end of the spectrum, and if you've got your own system for "interpolating" recorded waypoints, then that is exactly the same as keyframes, and:
if A==(recorder + playback) + fileexport(loaded for playback,interpolation))
then you are using keyframes and {A = cutscene_editor.}
