You really need to ask them at the station. Especially if it's something special that they want to run.
(As for me...
When I send in news items in to our local station(s). I send the video to YouTube and they run with that... easier on me... faster for them to get... and they don't care that it came from YouTube. I just put a comment in the comment box that gives them the ok to use it. I also send an email to them that states that they can use the video.
I bet I have had over 50 videos aired... I get '15 seconds' of fame. And that's the one reason I don't kill myself sending them videos.)
