Marie Campbell has been describing for over 20 years and is the lead trainer in Red Bee Media’s Audio Description team. She started out in London, helping to set up the BBC’s first ever AD department, where she developed editorial guidelines and new bespoke software while integrating the service into the wider, well-established broadcast chain. Marie has described for the majority of UK broadcasters, overseen the describing of 200 films on the theme of disability for the British Film Institute and been part of the pre-recorded AD team during the Winter and Summer Paralympics. She continues to be at the forefront of AD excellence, developing guidelines and using her expertise to train new scriptwriters and voicers in the UK, USA and Australia, tailoring the service to different English-speaking countries, while integrating workflows, maximising collaboration and providing ongoing support to new AD teams. Marie is currently looking at how e-learning can be used to facilitate AD training.
