I ‘moved’ from stills to video some six or seven years ago and have never regretted it. Some aspects are more complicated, others are made simple by the move to video. It is, though expensive!
A good camera £500-600; good tripod (with a fluid head) and monopod £250; high spec computer (at least 2.33G processor) £600; editing and post production software £80; two external HDD for archiving £120.
Then the need to learn and gain experience for which a lot of patience is needed
