Replicate and image mask

Hi(Bonjour)!
Here's the problem:
I create a nice big white text and want to use it to restrict a replicator to the form of the text itsel.
When I drag the text layer into the source image mask well in replicator tab, the replicator doesn't seem to limit itself to the letter's shape.
I encountered this problem when trying to learn this tutorial in Motion 3:

Hi(Bonjour)!
After Motion project file exchange with SpecialCase, here's a follow up:
As I understand, my project file works on another computer but not on my system.
So I correctly followed all instructions on the tutorial pages, but my system cannot render the "effect" of maping replicator shape by an image (by the way I haven't more success with shape maping either for replicator and emitters.
The problem seems to be related to Alpha cutoff command: o% give me a full rectangle (as expected) and any value greater than o% occults the replicator image.
I use a PowerMac G5 dual 2.3 4.5 gig RAM, ATI radeon X1900Gt G5 edition 256 meg VRAM, MAC OS X 10.4.10, quicktime 7.1.6, Motion 3.0.1, fresh install of FCS 2, no previous versions.
All other commands in Motion are working, with very few stabilility problem (if I compare to posts on this forum).
So, If someone got success with this tutorial project:
http://www.motionsmarts.com/tutorials/pain/pain1.html
please write here your mac specifications to see if there is an issue with hardware/software for this function (image or shape maping for replicator or emitters).
Thank you.

Mask and Image Control Commands

I am not able to use either Mask or Image Control Commands. They are always grayed out no matter what the situation, document, etc. Can anyone help me? I am using Pagemaker 7.0 and Windows XP. Thank you.

Mask is very simple. Overlay a shape over an image, select both and click mask.

Can someone point me to a tutorial on image masking and alpha channels?

Can someone point me to a tutorial on image masking and alpha channels?
Goal is to make a picture in a picture frame become a moving image.
I am trying now to figure out how to make a hole in a video by subtracting a 16x9 sized rectangle.
Thanks.

hi
depending on how complicated your shot is, you may be able to get away with simply placing the image within the frame on top of the background shot. Then resize down to fit. You may then need to tweak its corners using the corner pin tool to get it to sit in the right perspective plane. You may find you need to soften the edges of the top layer image so its not so sharp and hard. For this you probably would need to add a mask and soften its edges. Then you might need to add some noise and/or colour correction to make it sit naturally with the background image. and finally if there are any shadows cast over the picture frame you will need to add them back over the new image. You can use a black shape, with its opacity cranked down with a blur filter on it.
The manual describes all of these process pretty well.

Cannot reduce file size in Acrobat X due to "image masks"

Occasionally, when I try to reduce the file size of a PDF file in Acrobat X, I am getting the error message that the file was not re-rendered because of "image masks".
What precisely does this mean? How are image masks created in the PDF production process and how do I avoid them going into the file?
In this case, it was a simple Word document including a text and two semi-transparent GIF images on top of each other placed behind the text.
Any help would be appreciated!

Try to flatten the pdfs that should get rid of the masks (use Preflight tools).

How to remove the "Image Mask" labels under the effects tab in the Inspector window

I'm still trying to find my way round Final Cut Pro X after using Final Cut Express for many years. I don't know how I have manage to finish up with two Image Masks being set under the effects tab in the Inspector window. The Image Mask effects are not active (the box adjacent to the label is not blue) How can I remove the Image Mask label from the Effects tab in the Inspector window?
Thanks JohnH

Image Mask Error Message when Reducing Size of PDF

With my Mac, I embed jpg images in Microsoft Word documents, save them as pdf's, and reduce them. Size reduction often fails, with the error message "The PDF document contained image masks that were not downsampled". Jpegs don't have masks, so I have no idea how to fix this problem, and an extensive google search was of no assistance.

Use PNG images instead use an application such as Graphics Converter, Fireworks to convert to .png from .jpg.
Will have much better images that do not degrade each time they are opened and most often they end up being same size than jpeg's
Jpeg unless you save as a special type is a Lossy format and each time is open (and decompressed) then closed (and then compressed) losses detail
Just open and magnify a jpeg after its been open 5-20 times you notice an out of focus halo looking similar looking to water spilled on paper wil pen ink on it. And it get progressively worse. PNG on the other hand is not lossy and if the original is saved as png never degrade even when reduced in size or or expand within reason in size. I've being dealing with photos screenshots, images and other for years. Despite what other may say on this list may say if you want an image with little trouble for years of service save as png.

Revolution Theme Background Shadows or Image Mask

Hello Again.
Despites wise advise of ¨just call me dude¨I obtain what I need, He oppens a new interrogative.
How to modify background´s image mask. It drops some kind of shadow at the upper right side of the image and become´s dark in that place.
That is great, but I am tryiong to find how to eliminate it or make it less dark.
I know this is a hard question, but I´ll give a chance to destiny to point me in the right path.
I checked the adress http://digitalproducer.digitalmedianet.com/articles/viewarticle.jsp?id=67633 and opened the file ThemeDescription7.plist and search into it with plistedit pro, but I have no idea where to find a clue on that, as I am not a English reader, I have no idea about the name of that effect who affects the image I drag into the sceene and to the background. I looked for shadow, but no changes, blur, but no blur at all.
Thank´s for your help
AH

Hello, Arturoherva,
I followed what you are asking. I downloaded Plistedit pro, and found the steps to modify the Reflections blurring in iDVD 6 themes. The same process does not work for iDVD 7 (08), because the Revolution theme is not organized in the source file in the same way. I could not locate a similar folder with the Resource option.
I think this may be able to be done, but not with the same steps as given in the example on the link you provided.
There probably is a command to lighten the background of the Revolution theme, but the steps listed for PlistEdit are for themes prior to iDVD 8.
Maybe you should contact PlistEdit and get instructions for use with iDVD 7(08), and post them back here

No luck with applying Image Mask!

Im trying to add an Image Mask to a video clip in Motion.
I added the Image Mask to the clip per the instructions then added one of the Brushstroke movies from the Content folder in the Library.
The dashboard shows me that the movie is in the well.
But Im seeing no masking going on.
No matter what blend or source setting I choose, I see no masking.
What am I doing wrong?

I happened to be mucking about with the brushstroke clip the other day. If you're looking to have the image appear as the brush drags across, you can simply drop the clip on top of the image layer and set the blend mode to silouhette luma. Ya get something like this:
http://homepage.mac.com/longstrider/iMovieTheater12.html
I tried to apply it as a mask also, but because the pbrush is positioned at the bottom of the frame, it didn't do the trick for me.
Hope this is helpful

Image mask problem - positioning

Sorry if this has been asked before. I really did try searching before posting.
I was trying to get a text mask to work for me in FCE 2 but I can't seem to figure it out. I can almost get the desired effect with a video layer, a text layer on top of that, and applying "Travel Matte-Luma". I can move around the text or the video, which is what I want to do. But the video that shows through the text is grayscale. So, I tried adding an image mask to the video clip. It worked and was in color, but I am unable to move the text over the desired part of the video. Does this make sense? Any ideas?

Thanks for the help. If I use alpha it just turns everything black except for the text. I was playing around with it some more and found that if I simply chose "reverse alpha" (without applying a matte) I achieved the desired effect, EXCEPT the outline of the text was still visible. What am I doing wrong?

Motion 5.2 Missing Image Mask?

I recently noticed (probably coincident with update to 5.2, but not sure) that when I add an Image Mask, I can only see it in the Timeline, not in the layers. In the picture below, you can see the group in both Layers and Timeline, but only in the Timeline does the Mask appear. It's there; you can see the effect of the transparency gradient in the Viewer. Anybody else experiencing this? Anybody have an idea why and/or a suggested solution? Much prefer to work with Layers with Timeline hidden. Thanks for any suggestions.

You need to click the show/hide masks button.

How to use local variables to pass an image mask correctly

I'm kind of new to labview but i'll try to explain the problem as best as i can: I'm trying to pass an image mask (basically an image) to the next iteration of a while loop using local variables. I think the image passes through the loop with the local variable but i can't read from it correctly for some reason. And I don't think the problem has to do with local variables because i've tried using shift registers and that didnt work either. I think the problem is that you need to do something to read the image correctly again, like using IMAQ copy or something (that didnt work tho), but i can't figure out what the problem is. Does anyone know what the problem is? I know this isnt a great explanation and if its too confusing i could send some snapshots of the program or something. Any help would be greatly appreciated though.
Thanks,
Will

So i attached 2 snapshots of the program to give a better idea of the problem. The first snapshot shows an image getting written to the local variable SavedMask. The second snapshot, which is run on the next iteration of a while loop, shows the local variable SavedMask being read to other image operations. When i run the program, the SavedMask image is always displayed correctly on the front panel, but i can't read from it for whatever reason. I think the problem could be like you said, that im only passing an imaq reference, and i think theres a certain way to extract the image data. Do you know the correct way to extract the image data or how to pass the image data and not just a reference to the data.

Which pdf has an image mask?

Hi guys,
I am making a document in InDesign with many linked pdf as graphics and charts. When i export the InDesign document to PDF it says it has some Image Mask that were not downsampled. How can i tell which of my PDF has an image mask?
Thanks for any info,
Cheers,

Hi,
placing an image wich is not entirely displayed in an image area cause an image mask.
See attached screengrab, the second picture (with the brown area) will create an image mask, in InDesign as in any other software.

Image mask

I am working on a custom sized video in FCPX. File size is 8150 x 1200. Everything seems to go on but image mask, when i load a same size png mask is appears stretched. I test it on a standard video size 4K and it works fine. Is image mask not working with custom files?
I often work on those kind of products and i should fix the problem
thank you for your help.
Aldo

I tried using the file you posted as an image mask on a 8150x1200 project and I got similar results as you did.
Although the image used as a mask is the same size as the project, it got stretched horizontally, producing "fat" people.
However, placing the same image on the timeline as a regular clip does not stretch it.
This suggests a workaround, that in my limited testing seems to work. (emphasis on workaround, since I believe it should not be necessary).
Connect your would-be-mask above the clip, and change its blend mode to stencil alpha.

Image Mask vs Modify Composite Travel Matte

I have about 30 different clips that I have recieved as RGB and Alpha separated QT movies. I can get the clips to pull the luma from the alpha movies with the Modify>Composite>Travel Matte technique, but that leaves me with a ton of files in the timeline. I would rather be able to use the Effect>Matte>Image Mask technique, but for some reason when I apply the alpha movies to the RGB movies the alpha that is created leaves the RGB transparent.
Does the Effect>Matte>Image Mask not work properly? Is that why the only technique I see in the forums discussed is the Modify>Composite>Travel Matte technique?
Thanks for any info.

If you are able to set the mask image as the movie file, then you should try setting the mask type to luma, rather than alpha - since the alpha movies are probably black and white images which actually do not contain an alpha channel.

Deleting image masks

PC, Windows XP, Acrobat Professional version 8. I have a PDF file of a map (132 x 36 and 7 MB in size) in which I am trying to reduce the PDF version it is saved in to Acrobat 1.5 (Acrobat 6.x). I choose Document/Reduce file size, select 'Acrobat 6.0 and later', and then click save. Upon clicking Save I get an error msg. 'The PDF document contained image masks that were not downsampled.' and then another error msg. saying 'Could not find the XObject named 'Im0'.'. The resulting file comes up either completely blank (literally white) or partially blank (white). Is there a way to delete the image masks so the entire map is visible?

Have you tried copy/pasting the elements from the other Motion projects (by opening them all at once) instead of importing?
