hi there

i am trying to build a live render cartoon caption patch
i have been trying to combine and image (the speech bubble) and some text files (the words) and then render it over a piece of live video
this is the stripped back patch

i have only been able to render the text by using the jit.op @op, and combining it with the speech bubble png,making a single image with the jit.alphablend but when i pop this into a plane i loose the alphachannel and it renders out as box (instead of the shape of the speech bubble)

jit.videoplane @blend enable 1 @depth enable 0 @transform reset 2 @layer 1

any help much appreciated (i’ve spent many hours trying to work out this problem)
