Only talking head / moving powerpoint / music soundtrack only - no worthwhile commentary
Some combination of moving footage, interview, powerpoint and soundtrack. Voice over is clearly reading off or more music than voice over.
Good combination of moving footage, clips from the internet, powerpoint slides. Well edited, pleasing on the ear and eye.
Excellent video. Well edited, interesting graphics, very good soundtrack combined with professional voice over - not merely reading off notes. Evidence of own ideas coming through.
