I'm using Kdenlive 0.8 installed on debian via apt. (binary .deb, not compiled version)
I'm not able to properly use the volume effect on audio tracks: It seems that all the values inferior to 100% are considered as 0%.
If I set the volume of an audio track to 50% no sound is played.
In a similar way if I smoothly decrease the volume to 100% to 50% the volume decreases 'till it reaches 0.
Has anybody ever experienced a similar behavior?
