    If you don't need the shape to move...
    1. Cut the part of the clip you want to "filter"
    2. Create a black and white matte of the shape you want to filter - you can do this in the Titler, Paint, or whatever you want as long as the result is a format EDIUS can read and the result is the same dimensions as the source clip.
    3. Select both the matte and the (partial) clip in the Bin
    4. Right-click one of them and choose Convert | Alphamatte
    5. Choose the Luminance key and correct fill clip
    6. This will generate a new copy of your (partial) clip with an alpha channel.
    7. Now you can put this new clip over the original clip and apply a blur to just this clip.
    If you need the shape to move, then you'll have to use something that can generate a moving black/white video clip, again in the same resolution as the source clip.
    Rendering a keyed clip with "Show Key" option enabled is a good way to do this (though if you already could key the clip, then you shouldn't be going through this exercise).

    You really can't do that in Edius. There is no tool that would let you do shapes.

    Thanks for your reply, I don’t know exactly how I can do it in 3D PIP but as I said I don’t want geometric selection, I want freehand selection.
    Matt, how can I use custom alpha map in Edius? Would you please explain more?
    (I can't go to After Effect, it must be done in editing program)

    AFAIK, there is no simple way to do this in edius - but if your subject isn't moving much, I think you could do something with a custom alpha map?

    You best bet is to do it in After effects - Use the pen tool, draw your mask and animate it. Then feather it and ad blur to outside.

    Those 2 are the only options in 3D PIP. Usually if you use the elipse and then blur the edges you can get close to what you want.

    How can I blur define portion in video clip?

    Hi
    I have a question, can anybody help me?
    I want to blur around a person body, I want to know if I could select his body by region filter? (I don’t want rectangular or ellipse selection) If not, is there any way to do it?
    Thanks
Working...
