I have a camera set up to move in one direction slowly, then gain speed over time. I figured I would just make a simple curve to make the camera pick up speed, but im having trouble with the curves. I made a curve for the two key frames involved. It should make the camera gain speed, then maintain that speed for the duration of the animation, but it eventually slows down for some reason. The pic I attached has the info on it. Thanks for the help! 7774_fcurves.jpg.zip
to keep moving the curve needs to keep rising. That starts slowly (gentle slope on the left) speeds up but just before 240-ish levels off (slowing down) and stops entirely (flat line after 240-ish).
You either have to move the camera further out in space for the keyframe around 490 so the curve is a straight rising line between them (constant speed) or get rid of position keyframes for the camera after 240 and in the timeline select the camera (or the Null the camera is in if you are key framing that as I'm guessing) then use Functions/Track After/Continue After - then you just adjust the handle of the keyframe at 240 to get the straight rising line.
