For my first attempt I used a Flip Ultra 3rd Gen pocket camcorder, attached it to my bike, aimed it sideways cycling around London and then slowed the footage down using Twixtor. This time I used a Kodak Playsport ZX5 instead. While the Flip Ultra 3rd Gen records 720p at 50fps, the Playsport ZX5 can record 720p at 60fps. I found the extra 10fps really helped avoid blurring and gave much better results.
METHOD: I used two methods. As the Playsport has a plastic tripod thread and a curved base I found it wobbled when attached to my bike, so for the first method I just cycled with one hand on the handlebars and held the playsport with the other hand aiming it at whatever looked interesting. It worked ok.
For the second method I just picked a good spot and spun around 360 with the camera. I wanted the camera to move fast so when I slowed the footage down it would look like the camera was moving at walking pace while everyone else was frozen'ish. So spinning on the spot seemed ideal.
N.B. I know there's some warping in places. As too many things were moving there wasn't a clearly defined foreground to separate out motion for a matte surface. I actually quite like the warping in some places though.
LOCATIONS: first clip is outside a pub off Tottenham Court Road, then along Parliament Bridge, then along the Mall by Buckingham Palace, then by Liverpool Street station, along Marylebone road, and the final clip is the beginning of a charity race near St Paul's Cathedral.
I just took loads of footage and compiled them together. I actually ended up not using a lot of material I really like, particularly around Brick Lane, Covent Garden and Speakers Corner. As the video's already far too long I couldn't include them.
MUSIC: I made the piano piece to go with the video. A big raggedy but I think it works.
