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!

Title:
  No transparency on animated titles

Status in OpenShot Video Editor:
  Confirmed

Bug description:
  This seems to be around for a while but I couldn't find a way to fix
  it: When creating animated titles, they always have a gray background,
  whatever "alpha" settings I use. Instead of being transparent, the
  title totally obstructs the underlying video track. I *have* read that
  there was (?) a bug concerning using SKY vs. TRANSPARENT settings for
  Blender somwehen, but it appears not to have been fixed.

  I observe this on two machines:
  1. Ubuntu Studio 14.04 (64-bit), OpenShot 1.4.3 (versions *should* be same as below but cannot check right now)
  2. Linux Mint 17 (Cinnamon, 64-bit), OpenShot 1.4.3-1.1 and Blender 2.69-4ubuntu2, MLT & melt 0.9.0-3,  libavcodec54 6:9.16-0ubuntu0.14 (versions as Synaptic shows them)

  Both are the versions installed by the distro's software centers,
  respectively. I didn't risk messing up things by trying to add ppas or
  compiling myself, being a Linux newbie, more or less.
