The transition dialog is a little bit picky ;-) Reproducible: Always Steps to Reproduce: 1. Have a video with two tracks and clips using a dissolve transition 2. Double click on the transition 3. The duration dialog opens 4. Enter "7" as the value for seconds Actual Results: The duration doesn't change. You have to use "07" as the value instead. Expected Results: Duration should be changed even when no leading zeros are provided by the user. Kdenlive 16.04.1
