Hello XPression Users

I would like to register the attached video file as a material in XPression and apply refraction to create a transition effect.
(plz check the attached video file)

However, I want to use the black area of the video as an alpha channel to reveal the layer behind it. 

Is this possible within XPression?

I'd apperciate it if you coluld check it and give us any advice on this matter.

Thank you.

Only because I know it is a really busy time for all Ross staff with NAB happening in America, I wanted to get you a response.  What you are asking for is possible.  You will have to change blending modes in the material manager to make this video file an alpha. - Then if you want to wipe inside of a scene, you probably not only need to bring the video into your project as a material, but you also need to bring that video file into a scene director.

I tried to use an alpha mask on my own but it didn't work out, so I'm writing again. 
Where should I add the alpha mask to apply it? 
I created an alpha mask using the layer object. Is my method correct? 
Could you please explain briefly how to use the alpha mask?
Thank you.

Hi DK-Han,

incase you just want to use your black and white video as a reveal or transition you need:
1. have the black and white information in the alpha channel of your video - video tutorial B124 
Merging two Videos to Create an XPression Video with an Alpha Channel - Ross Video
or possible in After Effects with having the material as a luminanz alpha

2. just ad material -> then mask -> then video
It actually does nothing else then setting all the blending modes automaticly like in the pic. above. 

3. Create a layer in the scene and put your video mask and the material etc. you want to reveal in the layer  - be aware of Z-achsis or position above or under with the mask to work. 

The mask video can be draged in the scene director or have a start automaticly - all works.

From what I got above I think you had the black and white informatin only in the fill and not in the key (alpha) of the video.

Attached a example - incase I understood what you want to do wrong just mail me directly what you mean.

Cheers Nicole

Hi Pixmaniac

Thank you for your kind advice. Thanks to you, I'm getting the hang of it, but this task is still difficult for me and I haven't been able to solve it yet.

I want to create an effect similar to the attached video file.
(This video was created using Adobe Premiere Pro.) 

From the tutorial you provided, if I want to create a transition effect like the one I'm trying to achieve, should I register the video source in the brush transition in the Xpression Video Codec and register the desired video image in the alpha source?

Please check the second video file attached. 
What I want is for the second video to appear with a brush transition effect applied when transitioning from the first video.

Thank you :)

Hi DK-Han,

sorry I just figured that in the video coder (I used 9.7) with the mp4 format of your files you could not use "The Alpha from Video fill" and the Alpha from RGB did not work eather with what you needed.

So what you need is first just the video mask - and for that a Xpression AVI with the Alpha Channel having the black and white information. 
Do you have  After Effects?  Do you know how to do that?
None of your pictures need to be the fill (source) in this case the fill does not matter because you use just the alpha as the mask information.
 
Then to archive what you want there are 2 ways:
1. build a scene that has the transition - means the mask video in a layer and the picture quad published with material. Then in the sequncer you have to put them always a layer higher - so bothe scenes will be onair the one with the old picture and the one with the new picture - once the new scene is onair then take the scene before offline. Not very practicle handlingwise  but o.k. for just a few pics.

or better:
1 scene with 2 pictures - the old and the new both published. The old picture is always the one from the scene before.

Demoprojekt attached and later I will make a little explanation how to archive a different alpha in After Effects.

Only because I know it is a really busy time for all Ross staff with NAB happening in America, I wanted to get you a response.  What you are asking for is possible.  You will have to change blending modes in the material manager to make this video file an alpha. - Then if you want to wipe inside of a scene, you probably not only need to bring the video into your project as a material, but you also need to bring that video file into a scene director.

Hello XPression Users

I would like to register the attached video file as a material in XPression and apply refraction to create a transition effect.
(plz check the attached video file)

However, I want to use the black area of the video as an alpha channel to reveal the layer behind it. 

Is this possible within XPression?

I'd apperciate it if you coluld check it and give us any advice on this matter.

Thank you.

Hi Pixmaniac

Thank you for your kind advice. Thanks to you, I'm getting the hang of it, but this task is still difficult for me and I haven't been able to solve it yet.

I want to create an effect similar to the attached video file.
(This video was created using Adobe Premiere Pro.) 

From the tutorial you provided, if I want to create a transition effect like the one I'm trying to achieve, should I register the video source in the brush transition in the Xpression Video Codec and register the desired video image in the alpha source?

Please check the second video file attached. 
What I want is for the second video to appear with a brush transition effect applied when transitioning from the first video.

Thank you :)

Hi DK-Han,

incase you just want to use your black and white video as a reveal or transition you need:
1. have the black and white information in the alpha channel of your video - video tutorial B124 
Merging two Videos to Create an XPression Video with an Alpha Channel - Ross Video
or possible in After Effects with having the material as a luminanz alpha

2. just ad material -> then mask -> then video
It actually does nothing else then setting all the blending modes automaticly like in the pic. above. 

3. Create a layer in the scene and put your video mask and the material etc. you want to reveal in the layer  - be aware of Z-achsis or position above or under with the mask to work. 

The mask video can be draged in the scene director or have a start automaticly - all works.

From what I got above I think you had the black and white informatin only in the fill and not in the key (alpha) of the video.

Attached a example - incase I understood what you want to do wrong just mail me directly what you mean.

Cheers Nicole

I tried to use an alpha mask on my own but it didn't work out, so I'm writing again. 
Where should I add the alpha mask to apply it? 
I created an alpha mask using the layer object. Is my method correct? 
Could you please explain briefly how to use the alpha mask?
Thank you.

Alpha Mask is what you need.

I forgot that it's NAB season. Thank you for your response.
What blending mode should I change in the material manager?
Thank you.
