Hi,
I'm new to CompositeLab, I've tried it for some time and I find it is generally very powerful and easy to learn.
I have only a problem with garbage matte view.
In order to make precise/complex compositing work, I'd need to view the underlying layer while I'm drawing and moving the mask on the foreground. In CompositeLab, instead, garbage mattes appear filled in red and opaque when I'm in edit mode, and reveal the corresponding portion of the background layer only when I switch to the playback mode.
If I need to apply mattes to a very small portion of the frame- for instance, a person's eye- this turns the whole job harder, and unless I need animated freehand mattes it almost makes me regret the 'Track Matte' effect in Sony Vegas. The info bar menu, enabling to choose the view mode, is disabled when I work with garbage mattes. Is there a workaround?
Thank you

It sounds like you should be using masks, instead of garbage mattes. If anything on other layers is a factor in where the matte goes, then masks would be the proper tool to use.

More information about the difference between garbage mattes and masks can be found in this knowledgebase article.

OK,
now I understand the difference between masks and garbage mattes, but even using masks I can't view the underlying layer while I'm editing the shape.

Sure you can. Masks are applied in Project Overview mode, so you can see everything. There is a Track View available for them as well, so double-check the Canvas View Menu to make sure you are in Project Overview, but I'm pretty sure Project Overview is the default mode for applying masks.

The whole point of masks is to simulate interaction between layers, so it is necessary that you have the ability to see all layers when working with masks.

If you aren't able to see the other layers, you might still be in the Matte Toolset; what method did you use to apply the mask?

I can see the underlying layer while I'm moving the cursor in the timeline, but the shape goes opaque again when I select its track to move it. The default mode is Project Overview, I'm no longer using mattes.

Sorry, if you can provide a link to a screenshot of what you are talking about it would be helpful. I'm not following you.

A Mask is a transparent red shape of whatever shape you make it. Even If you have it set to Opaque Mask, you can still see through it somewhat, but if its set to Transparent mask you can see through it very well.

I'm not sure at this point if you are just expecting different behavior than the program offers, or if you are doing something incorrectly. The knowledgebase article I linked to earlier shows masks at the end, where you can clearly see the tower through the red area of the mask. Are you not geting that behavior from your mask, or are you expecting something else?

I don't get that behavior from my mask, although all params seem to be set correctly. Here is a screenshot of what I get.

OK, thanks for the pic. That looks to me like you are applying the mask to the lowest layer on the timeline. Since there are no layers beneath it, you would see through the red to the canvas background color (black by default). Is there in fact another layer below the layer you are masking that should be visible? And if so, are you sure the visibility of that layer is turned on?

I'm applying the mask to the forefront layer of the timeline, and all the layers are turned on.

Odd. How many layers do you have, and what are they? (video, effects, still image?) By forefront you mean the layer closest to the top of the screen on the timeline, yes?

What version of VisionLab are you running?

Are you talking about the color inside the matte? Go to the triangle in the upper left corner and turn transparency down to zero. Sorry, if that's not what you are talking about.

Rockfilmers - 0% transparent is the same as 100% opaque. 100% transparency is what you want for it to be see-through.

Axeman- I've tried both with video and still images. Does it make any difference? Yes, by forefront layer I mean the layer closest to the top of the screen.
'What version of Visionlab are you using?'
As I specified in the first post of this thread, I don't use Visionlab but CompositeLab, and maybe this is the point, as all video tutorials in the help area assume you have Visionlab. Is there any significant difference between CompositeLab and Visionlab for masking features?
I've realized right-clicking the mask makes it see-thru,but doesn't allow me to edit and move it. Remember, I'm not saying I can't see the transparency at all, I'm just saying I can't see the transparency in the red shape while it's selected for editing. When I select the video/still image layer I can see the mask transparency effect, but of course I'm unable to edit the mask itself.
I'm using CompositeLab on a Windows Vista machine, maybe this is the point. Are FXHome products tested on Vista?

Rockfilmers- mask transparency is already set to 100% by default, I didn't change this parameter and however it affects the final output not the red shape.

Sorry, I only mentioned VisionLab by mistake. The masking in VisionLab and CompositeLab is identical. The more pertinent part of my question was actually "What version are you using?"

What I was hoping to get was a list of your layers, and what type each of the is. The issue here, as far as I can tell, has to be with the way the project is set up. If things are set up correctly, then moving the transparency slider will absolutely have an effect on the red shape while you are editing. Either that, or perhaps you are running an older version of the program.

Yes, lots of people use the Lab products on Vista, they have been tested.

Rockfilmers is correct. He wasn't referring to the transparency slider in the toolbox, but the shapes menu up on the toolbox, which allows you to change the interface appearance of masks on the canvas. You can turn off the red 'fill' colour here.
