Hi all
Kdenlive 0.7 does not have a crossfade transition by default. You have to use a "composite" transition. For a discussion of this, please see this issue:

Very short: To get a crossfade transition, either use a luma transition that "looks right", or apply a composite transition, then add a keyframe to the transition at the and set its opacity to 0.
Feel free to chirp in with comments...
