First of all im new to fxhome so be nice!
Basically i was thinking what would be a good way to make someone invisible without needing to use a greenscreen.So this is how i made a quite a realistic effect kind of like the one in heroes.
This is what we will be doing form 2:24 to 2:26http://www.youtube.com/watch?v=reGMDR9pxvM
Okay lets get started,
First of all have a background plate.
(you want to have it not moving so try to use a tripod)
Then have another plate of your actor like doing something to turn the, invisible.
Okay now make a mask in any shape and then click animate put it over your actor and then look down to transparcy. It will be on 100 but you want to move it down to 20. Then move to the next frame and move to 30 keep on going up in 10ns till 100 and there you go!
Hope this helps!

Maybe I'm just not understanding you correctly, but if I am:
1) So long as nothing in the background has moved, you shouldn't actually need to do any masking for this to work (just use the transparency slider on the track with your actor instead).
2) Wouldn't you only need two keyframes, one on the first frame of the effect (transparency=20) and one on the last (trans.=100, or vis versa) so long as you are just changing it in an increment of 10 (or whatever) each time?
This is certainly the right idea though.

First of all i dont understand how you would be able to make the person go tranparent without a mask. Also if you were looking to do a more complicated fade rather than the whole body just dissapering, For example in the clip the bottom two sides start to dissapear and then his upper then does. You would have to use about three masks. And for when he is going transparent you want to make a mask then turn it down to 10 then next frame 20 next frame 3o next frame 40 unitl youre up to 100.

Okay, I see what you're saying here now.

You could so long as you kept it simple and made the whole actor disappear at once (and assuming there are no other actors in the shot). This is what I thought you were trying to do at first. The track with the background plate and the actor both have the same background, so making the entire track (the one with the actor) transparent would make just the actor transparent (the rest of the shot is identical on both tracks, so you wouldn't actually see it change.

Since you are using even increments of ten per frame, you only need to set the first and last frames and the program will fill in the rest. That's how keyframing works. Maybe this will help: http://en.wikipedia.org/wiki/Keyframing

If you mean you want someone to disappear behind a blanket, you'll probably need to use a completely different approach. Sorry, I'm not sure what the best way to do this is.

Are you using EffectsLab or Vision Lab?

Then that's normal unfortunately. ELab doesn't have as many blend modes as VLab does, which causes this to happen.
Either get Vision Lab or Composite Lab, or if you can't afford that, export each layer individually from EffectsLab with an Alpha channel (see the "render-->render settings" box) and re-layer them in another program (such as your editing program). Yes, it is hard to see what you are doing this way, but ELab really isn't set up to composite things other than the effects engines.

ok thansk so much i got composite lab and it worked just 1 more thing can u help me..my video is like playin at 2x as fast as it should and i didnt touch nothing and its only playing about 3 seconds of it...
how do i fix that>??

Yeah, the 2x speed thing means one of two things:
1) your frame rate is set wrong
2) you have your progressive/interlaced settings set wrong
Both of these are set when you start a new project. Make sure they match the footage you are importing.
As for only playing 3 seconds, I'd check your in and out points. You can also go to "render-->auto in-out" (might be called something slightly different, I don't have ELab on this computer to check for sure) or somewhere there is a setting to either play just the in to out vs. the whole timeline.
If in and out points aren't your problem (aka only 3 seconds of video shows up on the timeline at all) then I have no clue.
