If you want to put a title for the next piece, do it. But don't take any longer to label the piece than you would have used to just show black. Remember, viewers are fast forwarding through your tape. Reporters and anchors should use a montage first. Photographer resumes should show good visual storytelling.
Some news directors listen to the tapes first.
They listen for good writing and voice. Then they look at your appearance. Somehow get a copy of the newscast you might end up working on. Call friends, relatives, etc, to tape it for you. Some of you may be able to use club, sports or religious connections to get someone to tape it for you in the potential station's location.
