# Video Editing, Is there a way to make the speed value animated?

I added a Speed Control filter onto a clip inside the Video Sequence Editor. When I tried to make the Multiply Speed value of this filter animated, both by making it a key frame and by making it dependent from a driver, I got the error message: Multiply Speed cannot be animated.

• Am I doing something wrong?
• Why is this value not able to be animated?
• Is there a way, for instance an add-on to make it work?

My goal is to make a movie play at first very fast but then drop the speed continously until it is played in slow motion.

• I've added picture. If you go to properties of strip. Select speed effect strip, (open properties panel if not open yet), find "Effect Strip" section and deselect Use as speed. Then you should get Frame number which you can animate as any other normal property. – elmo May 8 '17 at 16:25
