I shoot really long form video learning classes. I'd love to have a way to add markers live into the footage as we shoot, so that when I import my footage into Adobe Premiere, I have markers to help me find the points in the class that needed to be edited.
Sounds like a feature request for Sony, because as far as I know, there's no feature that allows markers to be set in real time. In any case, the MXF format (the FS7's native video wrapper) doesn't allow embedded markers; that's why the camera produces those XMP sidecar files. .MOV allows this, so you'd have to be shooting to a Quicktime wrapper.
