    Vertical rolling lines with DSLR and projector

    I_don't_believe_it! Level 1

      I used a DSLR (EOS 60D) as a B camera for wide shot on a shoot in a dark lecture room the other day.  Vertical rolling lines were evident across the whole frame.  Whilst similar to scan lines on a CRT the lines were not restricted to the projection display.  I assume this is related to the shutter speed, but whatever speed was selected I could not get rid of the artefact.

       

      Are there any post production solutions for this?  Forunately I used another camera ( a proper video camera ) for the A roll and had much more control over the shutter speed.  The B-roll is not crucial but would be useful.

       

      TIA
