Il cinema al rallentatore

Multimedia   31.07.20  

In questo episodio di Vox Almanac, Phil Edwards esplora l'effetto slow motion e di come sia diventato parte della produzione cinematografica cinema.
La storia del rallentatore inizia agli albori della fotografia con i pionieri Étienne-Jules Marey e Eadweard Muybridge e i loro esperimenti sulla cronofotografia per arivare all'invenzione dello slow motion per opera del sacerdote August Musger nei primi anni del XX secolo.
Il rallentatore è stato fondamentale sino dai giorni del cinema muto, fino a diventare onnipresente nel cinema moderno e in televisione: dagli eventi sportivi ai musical, dai Sette Samurai a Bonnie e Clyde.

La stazione in slow motion

Wow   28.11.10  

Come sfondare con un video virale su YouTube. Una Casio Exilim FH20 e slow motion a volontà.

Both glides were filmed by sticking a – relatively cheap – digital camera out of the window of a train as it arrived at a station. The 'trick' is the camera collects images at a rate of 210 per second – but the film is played back at 30 frames per second. So, every seven seconds of footage that you watch corresponds to 1 real second. At least at the start, one real second is plenty of time for someone to move into, then out of, the camera's field of view, but isn't enough time for them to really do much: hence, the frozen effect. It breaks down towards the end not because I’m doing something clever with the frame rates (captured or replayed), but simply because the train was stopping! Thus, as it decelerated, any given person would be in view for longer, and have more time to point an arm, take a few steps along the platform, or maybe even notice me at the window. Any such action captured is still slowed down seven-fold during playback, just as with my usual static captures.
