Comment 3 for bug 1365851

Hello,

there is a workaround, you can read on http://www.mp-development.de/blog/18-openshot-blender-titelanimation-transparenz-fehler (german language)

you have to edit the phython-script files which controls the blender rendering in /usr/share/pyshared/openshot/blender/scripts/

1) search for:
            'color' : [0.8,0.8,0.8],
            'alpha' : 1.0,

and add the line:
            'alpha_mode' : 'TRANSPARENT',

2) search for:
except:
    bpy.context.scene.render.image_settings.file_format = params["file_format"]
    bpy.context.scene.render.image_settings.color_mode = params["color_mode"]

and add the lines:
try:
    bpy.context.scene.render.alpha_mode = params["alpha_mode"]
except:
    pass

Please fix the scripts. without the transparency working directly, this function is completely useless!
