I want to use python to create a series of strips and group them into a meta-strip. I have noticed there are several new_ methods on scene.sequence_editor.sequences such as new_clip(), new_effect(), new_image(), new_mask(), new_movie(), new_scene(), new_sound() but there is not one for the meta-strip.
What is the proper API to use to create a meta strip from several other strips?
def make_meta(scn, strip_list):
# magic goes here
strip_list = make_parts(scn)
make_meta(scn, strip_list)
