What's wrong with this effects? Speed effect is missing, crop/scale doesn't work - bring only black screen. Actual kdenlive on actual archlinux 64 bit

Speed is applied by right-clicking on the clip -> change speed.
You'll have to be more specific on what doesn't work on the crop/scale.

Thank You for speed effect solution, crop/scale work lke this: https://drive.google.com/file/d/0Bxp2UM ... p=drivesdk

Sometimes black screen, sometimes nothing, but work nothing
