I'm probably the only one who didn't like the pre-recorded look at the news at the TOTH. There's no real reason why Charlotte can deliver that live.
Given the comparable length of the new opening sequence and the use of 'vox pops' and inserts from correspondents, it's more likely to get out of sync if it's not pre-recorded. It also allows her to move from the desk to the screen. They do a similar thing on Franceinfo starting the headline sequence in one place and ending in another, and you can often tell they're walking while reading - one newsreader recently got caught on camera not making it to her seat on time!
