Here is my second report about the implementation of effects in Pitivi. I am going quite well with this project, and I now have almost everything ready to be able to add effects to videos. The dragging of effects to the timeline is almost ready, but I need to work on it a bit more to be able to show you a screen-cast! I hope it can be done next week.
Sorry for this kind of useless post, but I just wanted to tell you I make good progress, and I should be able to show you more soon!
You still can have a look at my git repository
