<p class=MsoNormal><span style='color:#1F497D'>As I've been doing some green
screen tests for something else I just did a quick test with a .flv
exported from Premiere. You have to select the encode alpha channel option as
detailed here http://blogs.adobe.com/premiereprotraining/2010/07/exporting_video_with_an_alpha.html
so that the .flv includes the alpha channel. The problem is if you're using
toolkits rather than xerte I doubt you can achieve what you want without
changing some code. A couple of issues I can see...<o:p></o:p></span></p>
<p class=MsoNormal><span style='color:#1F497D'><o:p> </o:p></span></p>
<p class=MsoNormal><span style='color:#1F497D'>1. if you import the .flv into
the video page type in toolkits it should import ok and retain the transparency
of the .flv but that page type has a white panel behind the clip so the benefit
of the green screen is lost. You can hide that with code or remove it
altogether by tweaking the model and to be honest I think wherever the white
panel is included in different XOT page types there should be an optional
property to hide it but I guess that could be something for a future release.<o:p></o:p></span></p>
<p class=MsoNormal><span style='color:#1F497D'><o:p> </o:p></span></p>
<p class=MsoNormal><span style='color:#1F497D'>2. In the video page type you
also get the controller by default with no option to turn it off so depending
on what you're trying to achieve that may not be desirable.<o:p></o:p></span></p>
<p class=MsoNormal><span style='color:#1F497D'><o:p> </o:p></span></p>
<p class=MsoNormal><span style='color:#1F497D'>3. Similar issues apply to swf's
containing transparency e.g. the flash animation page and image and sound page
contain the white panel. However you might be able to achieve what you want by
using the column navigator page with an optional image property added - that
also allows selection of a .swf but doesn't include the white panel so if the
swf is transparent it looks as it should.<o:p></o:p></span></p>
<p class=MsoNormal><span style='color:#1F497D'><o:p> </o:p></span></p>
<p class=MsoNormal><span style='color:#1F497D'>I guess to summarise both
toolkits and xerte support transparency in .swf .flv and of course .png but it
depends on what you're trying to achieve whether you can do this without
changing code or by using xerte rather than XOT.<o:p></o:p></span></p>
