Silver-screen audio trick can smooth jerky videos on cellphones

London, Nov 3 (ANI): Researchers suggest that an effect used since the early days of cinema to make the action appear smoother can actually help in improving our perception of jerky videos sent to cellphones.

Earlier, fast music helped to create an illusion of motion in movies that could make the action appear smoother.

The research team led by Salvador Soto Faraco at the University of Barcelona, Spain recruited 15 people and showed them films of flashing discs of light that increased or decreased in size.

When the discs flashed rapidly, they appeared to move forwards or recede.

At lower flash rates, they only appeared to move when accompanied with beeps that increased or decreased in volume, reports New Scientist magazine.

The researchers insist this shows sounds can fool the brain into seeing motion even without visual cues.

This trick can make low-frame-rate video footage transmitted over a low bandwidth seem less jumpy. (ANI)
