I am hosting a blacksmithing demonstration for about 50 ppl in a few weeks, and would like to video and project on a screen so they can see up close better as they are watching live from the "bleacher" setup they are viewing from. What would the cheapest(most reasonable) equipment available be to do this ( approx. cost?). I know this is a fairly vague question but I do not know much about this equipment. Is there a short reasonable answer? it'll be about 4 hours worth of demonstrations worth that I would like to actually record and project at the same time - is this possible? - Jeremy Knippel - Thank You for any advice.
