HERE IS A BETTER SOLUTION THAT YOU SHOULD RECOMMEND YOU SUGGEST TO
USERS. Other than exporting out an image sequence.
The other way that I way i was able to do it and you
should use as a work around is as follows:
1Make a green file
(png or jpg)
2Import the image
into your scribe
3To make this a
background:
1Move it to be the first item in the timeline
2Right click and move it to the background (so everything else goes
over top of it)
3Set all of the Animate/Pause/Transition properties to 0 so it just
appears.
4Then export the
.mov movie. (this replaces your having to stitch the sequence back together in
a media program).
5Import to Final
Cut Pro/Premiere/AfterEffects and just key out the green. (NOTE: This is
the same outcome of your importing image sequence).
Here are the two videos:
1. Videoscribe exported as .mov with green background.

2. After Effects with keyed out videoscribe included as overlay.

Hi Dough,
Thanks for the tip, these methods actually will yield slightly different results. The reason we recommend a .PNG sequence is because there will then be nothing to chromakey out, this can make edges cleaner which is always a bonus when doing this sort of work.
However if you're happy to use the chromakey (green/blue screen) route then there is another way you can do this as well. By changing the paper to the clear paper type, you can then set the background colour to 00FF00 (green) or 0000FF (blue). This will save having an element appear instantly, and may make panning around the scribe a bit easier.
Thanks again,

That works too. As for the edging. Because it is type when keying you can really tighten the edging, so you won't lose any sharpness. But this is by far what video people would do over the png sequence. Cleaner and less possibilities of something going wrong.
Cheers,

@Elliott where is the colour setting I can't locate that?

To change the canvas colour, click the brush icon at the top of the screen and click the colour square in the resulting window.
