> In fact, the functionality you're asking for was different from the

> need for this functionality is there too! I think we have to dissect two
> use cases here:
> 1) For preparing animation work and doing quick annotations the current
> tool is awesome already - we use it in our studio often and are very
> satisfied with it!
> 2) For doing some motion graphics stuff (like drawing frame by frame and
> then exporting it as an image sequence / having it as a seperate render
> pass) it could be equally awesome - every bit is there, but it's too
> cumbersome to work with. I already talked with Sergey about this feature a
> while back - but my lack of time made it impossible to tackle the
> implementation. I'll append some information about how and why this second
> use case would be useful - and how we are doing it at our studio at the
> moment (btw.: we could use AE for it but we love Blender too much to use AE
> ;) )

> Our use case
> -------------------
> Say we got a video file with an actress in front of a green screen. She
> moves her finger to the music and I want to draw the outlines of the finger
> as an overlay like on traditional 2d animation. I can do all this perfectly
> with the current system (onion mode, strokes persisting only one frame..)
> but when it comes to rendering we're almost lost... What we would need is a
> GP layer that would contain only the strokes and an alpha mask. Then we
> could easily compose them over a footage and alter it when needed.
>
> That's exactly the effect in AE http://youtu.be/rAhFDMDwzl0?t=4m26s
>
> How are we doing it atm
> -----------------------------------
> We're doing it by stroking with the GP first, then deleting all objects,
> assigning this GP Datablock to the scene, set the "transparency" setting on
> the render Tab to "transparent" and render out an OpenGL animation (that
> contains only the drawing) through the camera. Then I import it back into
> the compositor and add it to my footage... hope you see how useful it could
> be and how cumbersome it is atm - too much importing - exporting to be
> quick and easy..
