sambient

One of the things I've seen in other's videos is an effect where characters

are moving through a scene , either having a translucency or they are whited

out. First I'm wondering if there is a name for this type of effect. Then,

is it done via an alpha channel and or green / blue screen ? I'm not sure

how to even approach it and googling with vague words didn't seem to help.

maybe post a picture of what you are talking about? if you mean "ghost in a room" type effect ("my god, he's walking right thru the bed!!"), then it could be simply the room shot empty, composited with the room shot with a bed in it and a person passing thru. Chromakey could work well, too.
