The show reel i have created and most would if putting in a Trailer, would be of mixed projects.
Their own stuff and also maybe lets say- Trailers been re-made.
Sometimes a lot of editors are discredited when someone see their work, because of the actual quality of the footage they have used, coming from a cheap camera as apposed to using multi million dollar equipment to capture the clips as lets say Hollywood does, and editing that.
Doing a trailer from their footage captured is just away of making the person watching it stop looking at the actual footage and start looking at how it was edited.
To answer what you said about the trailers being good enough why edit them(along those lines)
Half the trailers made for these big productions are total junk
Take a movie called Wolf Creek (don't know if that movie was big over there)
but it simply had some of the best cinematography your's ever going to see of the Australian outback, some of the best shots I've ever seen in movie making alround actually
HOWEVER, when they put some of the trailers together for this movie, in my opinion
(and it is only my opinion)
for all the footage they could have chosen to use/to entice people to come watch this film, they seemed to compile only the craap of it, and use that
(I'm not saying there's not plenty worst jobs done on trailers than wolf creek, but that's just one that comes straight to mind)
If given good footage to work with, i think i could do better than half those production companies when it come to at least making their trailers for them.
so end conclusion, - if you do re-do a trailer, and it turns out better than the original which they pay separate companies big dollars for, then i think a perspective employee will stop and take notice
Anyway all that aside, thanks for all your help, it's much appreciated
All knowledge is good knowledge, so what you've said is well taken on board, thanks
