Bluescreening Without a Bluescreen

Hi,
I Know this has been asked many times before, but I think the topic has long gone.
I remember once seeing a tutorial that showed how to oick out the actors from normal footage without the need for a bluescreen.

Can anybody point me to a tutorial on this?

I think its called difference masking / keying.

Many Thanks

 

Have fun!

 

I think it's called Delta Masking. I remember seeing a tutorial somewhere, but don't remember. I would like to see this to.

EDIT: Woah, same thing at the same time.

 

Thanks a million!

 

garbage matting?

 

Oh yeah.
That too.

Have fun!

 

Bluescreening Without a Bluescreen?

I believe thats called using a Greenscreen

 

And to think I thought that I was all but forgotten
I just happen to get another tutorial up tonight. How to lightwrap in After Effects wihtout the plugin!
Lightwrap Cheat

 

We used yellow, and white screening on ADOTF.
I must say yellow worked flawlessly!

 

IS there a way of doing this with Ulead MSP.... this sounds very useful....and its all i got

 

Yup,
Right click you video on the timeline, select Overlay Mode... and set the type to Difference. This will get you started anyway. You'll need to adjust the Blend setting to see the effect.

You will use this to create a mask video between your action and background. Then you can output the mask to a separate file to be used in compositing in a new background.

I haven't used this feature yet myself. Needs to be toyed for a while to really make use of it.

Have fun.

 

Got a tutorial by any chance?

 

any way to do this in adobe premiere...?

 

No pressure, huh?
You know, I'm supposed to be packing .....

Oh, what the heck. I need to use this for my own film anyway.

Here you go:
Difference Key Compositing in Ulead Media Studio Pro Tutorial

(Sorry, can't help with Premiere. Maybe some of the same concepts will apply though.)

Have fun.

 

Thanks padawan, you've been alot of help to me on these boards.

 

Never ceases to amaze me man!
Nice tutorial!!!
I'm jealous
Trivia : The reason why I also called it Delta Keying was because it's quite similar to current video compression where only the differences between the images are stored (They're simply called Delta images).
Again, thanks goes out to a former TFN poster Nik who mentioned the theory of it on these boards in the first place...he was the inspiration this extreme form of garbage matting!
