Created attachment 179900 [details] pictures to illustrate the problem before and after using the "Custom effect" generated by the "Save Effect Stack" SUMMARY The duration values of fade in/out effects change after saving by "Save Effect Stack" option to the default durations of fades in the "Misc" window in "Configure Kdenlive" (in my case, 3 sec). I have included two pictures to illustrate the problem before and after using the "Custom effect" generated by the "Save Effect Stack". STEPS TO REPRODUCE 1. 2. 3. OBSERVED RESULT The duration values of fade in/out change to values other than I defined. EXPECTED RESULT The duration values of fade in/out must remain the same and not change to other values.
