Hello! I'm having a problem with Sony Vegas pro 9 - I added three tracks in a project, the middle one is set to "burn" and has a solid blue media generator on it. Then on the top track I have a clip with the transparency set to about 90%, and that track is set to default (source alpha). And the last track has a song on it and that's it. Whenever I try rendering it just comes out as a solid blue colour and the music playing in the background but I can't see the clip at all. Why is this happening? Can anyone help me please?
