Hey,
Was wondering if anyone could give me a crash course in low budget blue screen before thursday?
I basically have this weird idea of blueing out a window in the in the mastershoot and then in the edit suite having something happen outside that window which i will layer over the top.
I am using avid HD and was wondering if this is 1. possible 2. easy and 3. how do you do it?
Please please help!?!?!?!?
Cheers
Salvo

It's easy to do. But you will need an editing programme like Adobe Premiere Pro to make it work.
Firstly, whatever you are bluescreening has to bee VERY EVENLY LIT. This is important, cos if any of the blue is picked up as grey or black on camera, you're shafted. I would suggest lighting the screen and the actor SEPERATELY.
Also keep a few feet between the actor and the screen, and try and avoid shadows on the blue screen.
Do plenty of takes on this as well - trust me on this part.
As far as blueing in Adobe, it's easy once you figure it out - but I'd suggest you get hold of a manual. Search the net, cos if I explain it properly, I'd be here all night. But you must use a filter on your footage of the blue screen - which removes all the blue in the shot, and then in seperate time line, have the replacement footage.
I learnt how to do it for my first feature, but it took a few goes.
If you're blocking out a window, make sure you seal the edges of the window tightly with blue and you use a wooden board or something that won't let the light through. Bin bags are a flexible substitute. Shooting at night will also hide a multitude of sins.
Key elements then are: light well, position actor right and shoot lots. If you do get stuck in the edit, give me a buzz. I can email you the full crack on how to do it in Adobe Premiere Pro. And shooting HD - you have to get the shot tight, cos it'll pick up those mistakes.
Cheers - Tom.

follow all of tom's tips for shooting they're spot on.
as for the editing, i only know how to do it on final cut pro. i don't know how it works on avid, but you'll need to give the clip a filter to rid of all the blue (or green) and then have what you want in the blue, underneath it on a seperate timeline. i'm sure you can work it out if you have a look through the filters.
hope you get it done mate. i did some experimentation with green screen ages ago, but i just wore a green t shirt, and it worked to an extent, but because of shadows etc, it was never com-pletely see through. i'll try get it edited and put it up in the short film making forum.
