Britain In A Day: Creating a time capsule for future generations
Some of you may remember Video Nation in the 1990s - a really ground-breaking project where the BBC trained a group of people to use what were then cutting edge camcorders to record their lives on video for a BBC Two series.
The result was fascinating, intimate and raw, sometimes funny and often surprising but most importantly it gave the public a chance to tell their own stories - and it showed us what life was really like for people from all walks of life living in Britain at that time.
Flash forward two decades to 2011 and technology has moved on so much that everyday people all over the country are recording snippets of their lives on minicams, mobile phones and digital cameras.
Recording life in Britain has never been easier.
Whether it's personal family moments, footage of the royal wedding celebrations or shocking images of the summer riots, we're fast becoming a nation of amateur filmmakers.
And the great thing is that although the footage might be a bit wobbly and rough round the edges, for the first time ever, home videos are high enough quality for us to broadcast.
So for some time now, I've been trying to work out how to encourage this new found British talent and reinvent Video Nation for the present day to engage with people's hopes, fears and passions in this country on a scale that's never been possible before.
With the Olympics coming to London next year, I think we have the perfect excuse to create a snapshot of Britain and show the world all the variety and intimacy of people's lives here, whether it's a nurse working in A&E in Newcastle, a farmer living in the Welsh valleys or a student studying in Edinburgh.
Life In A Day used footage shot by ordinary people all over the globe to tell a story of one day on earth, to show future generations what it was like to be alive in 2010.
And it got us both thinking about how we could build on the experience and expertise he gained making the film, and make it work for the UK. Soon afterwards Britain In A Day was officially born.
There is no doubt we are living in interesting times in this country.
We're in the midst of the worst economic crisis since the 1930s with the gap between rich and poor ever widening, and we're also about to celebrate the Queen's Diamond Jubilee and play host to the Olympic Games.
So this is your chance to make history, get involved and help us create a definitive self portrait of the UK at an important moment in time.
On 12 November I want you to get out your camera and record something that captures the uniqueness of your life in the UK, whether it's something you're worried about, something that makes you happy, or something you particularly like or dislike about living in Britain.
You then need to upload the footage to the Britain In A Day channel on YouTube, where the director Morgan Matthews and his team will begin watching all the footage and cutting a selection of the clips together to make a feature-length film that will be shown on BBC Two next year ahead of the Olympics.
Britain In A Day is about more than just a film though. All the clips uploaded to YouTube will be kept in a permanent online archive - a sort of time capsule for future generations.
Think how fascinating it would have been if our grandparents and great-grandparents had filmed their day and told us what they thought of Britain, their hopes, their dreams and their fears?
I hope this is what the Britain In A Day archive will give to our grandchildren and great-grandchildren.
The success of this project relies on you, so I hope you will take this opportunity to show the world - and future generations - what life here is really like.
Morgan Matthews will be back here before the film is broadcast to let you know how we get on...
