Thanks guy
About Pencil i think it's a wonderfull free soft. Maybe it lacks some options.
For sample: if i select a number of frames i can't duplicate those (ex walkcycle). Maybe it's possible but i dont now how :p
Second sample: You cant modify the layers opacity.
An other thing: i have tryed to export my sequence in .mov but it doesn'n works. Any error window just clic and nothing

Have you an answer for that ?
To leave it, it's very nice soft!!
Next step for my animation the clean layer!
shut up and DRAW
