OK. I'm stuck. I'm creating a project using HDV from two sources (Canon 60D & GoPro HD Hero2), as well as some still images and some HD video content from a Canon G12. All of these formats have different screen dimensions. In order to get them to display correctly it seems the best way is to make each source-type its own sequence. So far, so good. But when I playback the video, I want these different materials to be combined in the edit, so that the video can cut amongst them. This is what I can't figure out. How can I create a video that uses all these different varieties of source content? If I use sequences so they display correctly, how can I make the video switch between sequences on playback? Is there another way to go about it that I'm missing? Thanks so much for your support.
