[SOLVED] Pre-Post animation spline NOT constant?

This is kinda hard for me to explain, but I try...

Is there any way I can set a animation spline to interpolate before and after animation graph to maintain a slope/speed instead of a constant?

Pre, Post Animation graph?

in the picture, I have camera motion between frame 127-151. when I render the camera with motion blur(MB), the MB will look wrong because there is no before(frame 126) and after(frame152) animation to compute the correct MB.
I know I can manually create key frame to work around this, but shouldn't it be an option to set to have animation curve interpolate(Green Dash line) or Constant(Blue line)

Have you tried the pre-loop and loop options in the rightclick menu from the spline view?
I think that might help you out for this specific case.

Oh, Thank you. Sander de Regt
At first it is alway gray out, so I miss it. (so you have to select a spline first)
Imagine it would be some sort of option on the UI or menu. Like a global setting of some sort.
Now I understand, it is a setting per spline. which is good.

In addition to what Sander said,
RMB and selecting "Gradient Extrapolation" does a good job in this case as well.

Nice one. Thank you
