Don’t have a GL2 but I do have a GL1, and with the switch not in frame mode, it captures 60i. Setting interlace mode to blend will do just that, but gives you kind of a double image, which makes the video look smoother if your subject is moving fast. If your video has no fast moving parts in it, try interpolate. It gives you a clearer picture but can look jumpy during fast moving video. Hope this helps, Danny Hays
