CobraVision, Cobra Beer's short film competition, is introducing a new format in its third year.

For the past two years, CobraVision had screened slots of 10 five-second films during advertising breaks on itv2, itv3 and itv4.

From May 1, the five-second slots will be replaced with a 50-second film playing before films on itv4.

Prizes in the competition include software and a cash prize of £10,000 and competition details can be found at www.cobravision.co.uk.
