I have recently bought a new Hp PAVILION laptop with windows 8. I imported video footage from a night I recorded for university. However the footage when put on my laptop tried to import to pictures instead of videos. This has resulted in a loss of visuals but not a loss of sound. Is there a way in which I can recover the lost visuals on my computer as the original footage was wiped by the university before I had a chance to realise the error.
