Fading Out An Image Mask

I've got aproject I'm working on where I want to do a reveal for a logo as the camera flys through a cloud.
I have been playing around with a few things to do this and have finally come down to using the Smoke Cloud generator as an image mask and this works pretty good.
The problem is that when I'm out of the cloud I want the image mask to gently go away but it isn't working as smothly as I would like it.
I've tried offsetting the mask and a few other things but basically I just want to lower the opacity of the effect out or fade it out so it's a smooth removal but there's no options for that in the mask options and it won't let me apply any behaviors to it.
Any ideas? Also, any ideas of easier or better ways to do that reveal?
thanks

I think I recreated your setup. The Smoke Cloud works quite nice as a mask. Neat trick.
The problem is there are almost no controls for the Image Mask. So try working on the emitter.
In the Smoke Cloud emitter, ramp up Scale, under Master Controls, until the edges of the image aren't being affected by the smoke. You have fine control to ease that as much as you want, and create a nice fade. It works in the demo project I just created.
Another way I've dealt with trying to fade in/out masks:
Duplicate your logo layer, which has the smoke mask. Delete the mask. Then fade out the first one, and fade in the second one (without mask) to make that transition. In this case, you probably want the second logo underneath the first to sell the illusion of the smoke.

Gallery image not fading out

Hi
I have two galleries. One using spry 1.4 code and one 1.6.1. The 1.4 gallery fades out an image before fading the new one in. This is what I want.
But the 1.6.1 gallery the image does not fade out. It just goes to white (or opacity 0) No fading occurs. The it fades in the nex image.
Can some one explain what is wrong with the code in the 1.6.1 gallery?

Hi.
Never mind. I found a post about the bug in gallery.js
gBehaviorsArray["mainImage"] = new Spry.Effect.Opacity(img, Spry.Effect.getOpacity(img), 0, { duration: 400,
finish: function()
should be ...
gBehaviorsArray["mainImage"] = new Spry.Effect.Opacity(img, parseFloat(Spry.Effect.getOpacity(img)), 0, { duration: 400,

How to fade in/out multiple images before image faded

Hi all,
I plan to do multiple images fade in/out using UIImageView just like Flicker iphone app.
Here are the steps:
1. Load pic1.
2. pic1 move from left to right.
3. pic1 will slowly turn to become transparent while still moving.
4. Same time pic2 is moving from right to left.
I am managed to have the pic1 slowly fading out after it stop moving and pic2 move in at the same time. However what i want is to have the pic1 slowly fading out while it is still moving.
Can anybody help me to look at my code below: Thanks.
- (void)viewDidLoad {
[super viewDidLoad];
CGPoint newLeftCenter = CGPointMake(180, 240);
[UIView beginAnimations:@"move1" context:NULL];
[UIView setAnimationDuration:6.0f];
[UIView setAnimationCurve:UIViewAnimationTransitionFlipFromRight];
[UIView setAnimationBeginsFromCurrentState:YES];
[UIView setAnimationDelegate:self];
[UIView setAnimationDidStopSelector:@selector(movingStop:finished:context:)];
pic1.center = newLeftCenter;
[UIView commitAnimations];
- (void)movingStop:(NSString*)animationID finished:(BOOL)finished context:(void *)context {
if ( [animationID isEqualToString:@"move1"] ) {
CGPoint newLeftCenter = CGPointMake(200, 260);
[UIView setAnimationBeginsFromCurrentState:YES];
[UIView setAnimationCurve:UIViewAnimationTransitionFlipFromLeft];
[UIView setAnimationDuration:3.0];
pic2.alpha = 1.0;
pic2.center = newLeftCenter;
[UIView setAnimationDelegate:self];
[UIView setAnimationDidStopSelector:selector(movingStop:finished:context:)];
[UIView commitAnimations];
}

I'd need to write a test bed to get this right for you, but as a first approximation, I think you'll want to do something like this:
- (void)viewDidLoad {
[super viewDidLoad];
// assume pic1 is now visible at its left starting position at full alpha
// and pic2 is at it's starting position to the right, either on or off screen
[UIView beginAnimations:@"move1" context:NULL];
[UIView setAnimationDuration:6.0f];
// --> this isn't an animation curve; just use the default for now:
// [UIView setAnimationCurve:UIViewAnimationTransitionFlipFromRight];
// --> leave this out for now:
// [UIView setAnimationBeginsFromCurrentState:YES];
// --> doesn't look like you need a stop method so leave these out for now:
// [UIView setAnimationDelegate:self];
// [UIView setAnimationDidStopSelector:@selector(movingStop:finished:context:)];
pic1.center = CGPointMake(180, 240);
pic1.alpha = 0.0;
pic2.center = CGPointMake(200, 260);
// I don't think you said whether pic2 is fading in, but if so, add this line as well:
pic2.alpha = 1.0;
[UIView commitAnimations];
Again, the above is only an outline, not working code. If you need more help I might have time to make it work this evening, ok?

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.

Faded-Out / Trimmed DDL's Selected Text in Adobe Reader X(10)

Hi folks,
My PDF form look good in all the preceding versions of Adobe Reader, but after upgrading to Adobe Reader X(10), the drop-down list box's selected text is getting faded-out/trimmed from it's right-side as you can see in the enclosed image.
By the way, the text is in Hebrew.
Any idea why this is happend and what can I do?
Thanks,
Yair

Tow conclusions about my problem:
1. The problem occurs only in Dynamic saved PDFs.
2. It's about bad RTL support in Adobe Reader X(10) and this is a very good workaround: http://forums.adobe.com/message/2008415

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?

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.

How to disable fading on dragged images while still being able to drag the images themselves?

When you drag an image, it will be faded out from where your mouse was when you dragged it. I want to be able to see the whole picture, no fade. But I still need to be able to drag the image itself. I've looked at nglayout.enable_drag_images in the config, but it just stops me from being able to drag the image at all.

I'm sorry, but I don't think there is a way to do this... Most operating systems fade items when they are being dragged, and I don't know if there is a way to counteract that without custom code to handle drag and drop.

Image Mask doesn't import from FCPro to Motion?

I have some footage in final cut that i put an image mask on. The image mask was created in photoshop and knocks out a rectangular shape in my footage. Works great in FCPro.
I export it out as a .MOV with the animation CODEC set to millions of colors+. I read that codec is the only one that retains alpha channels.
I thought my image mask would create an alpha channel but when I import that into Motion, their is no alpha channel and the rectangular shape that should be invisible is now visible.
Any suggestions?

Check out the sequence settings of the FCP sequence you're exporting from.
If it's NOT animation millions +, then you'll need to export an UNrendered
sequence using Quicktime conversion to animation millions +
to get the alpha channel. If you render it before exporting,
you lose the alpha channel.
If the sequence settings are animation millions + , then it doesn't matter.
BTW, both JPEG2000 and PNG also support alpha channels.

Image Masks Not Downsampled

Hi,
We have a PDF that we want to reduce the file size. When we select reduce file size, we get a window that reads "document contained image masks that were not downsampled". What does this mean? The 20 page document contains a lot of cut and paste images of maps and site plans that were built in PowerPoint and InDesign. Using Acrobat 9.
What steps do we have to take to correct this so we can reduce the file size?
Thanks
Barb

It means that the images have a vector mask controlling which areas are visible (acting as a crop). These aren't affected by a RFS action as the vector data is as small as it can be, but the warning is shown because if the underlying bitmap image is resampled, there may be some issues around the edges of the mask (e.g. if the mask very accurately cuts out a shape from a background, some pixels of the background may appear if the image PPI is reduced).

Image Masks?

I've always gotten this warning after saving a PDF containing JPEGs. What is it, how does it affect my final PDF, and how can I fix it?
My main concern here is whether or not I could be getting smaller file sizes out of my final PDFs if this warning were "fixed".
"The PDF document contained image masks that were not downsampled."

See my explanation of image masks here: http://forums.adobe.com/message/4227572#4227572
It's not really something you need to "fix", it's only a warning because in some cases it might lead to strange visual effects around the edges of a masked image.

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.

Clipping path versus image mask?

I've been doing a lot of clipping paths lately and I'm considering purchasing PerfectMask 5 from onOne Software to make that process a little easier. It looks like PerfectMask creates image masks. What are the advantages and disadvantges of each?

If you've mastered the Pen tool, then stick with it. You will find it faster and more accurate ( in most cases ) than any "automated" masking tool / plugin. If you haven't mastered the pen tool, and you serious about being an expert in photoshop, then it's time to bit the bullet and master the pen tool.
With that said, I've used photoshops extract tool, Vertis Fluid Mask 3, OnOnes Mask Pro, and I still prefer the Pen tool for speed, accurate, and flexibility. I just moved to CS5 from CS3, I've heard the refine mask tool is excellent, tho I haven't had a chance to use it much yet. The other automated mask tools work good on things like smoke, hair, transparent, and objects where the pen tool can't be used because of the hard edge. Again, I've been told the new refine mask tool in photoshop CS5 really does a great job with these areas.
I found the automated programs had a learning curve. Not all that easy to learn. You don't just launch them, push a "mask my photo" button, and shazamm!! They do take time to learn, study tutorials, etc. OnOne Mask Pro I found easier for me to learn than Vertis Fluid Mask. Now if your going to use them, day-in, day-out, then I'd imagine you'd get very good at it. (just like the pen tool).
So don't be too quick to lay down your $$, both have free trials, so go there first and try them on you typical images to see what you think.
Maskerade and Primematte are two others.
Just my humble opinion
good luck.

Multiple Image Masks

How do I create three individual image masks on three separate videos (which I know how to do) and then be able to move the videos behind the masks without the masks themselves moving?...
...all I have used to date is the Image Mask filter with a white rectangle covering 1/3 of the screen...should I be using a different filter or effect?...

...my intent is to specify exactly where a clip will be shown having the screen split with different camera angles, while at the same time showing only a portion of the original clip, and being able to motion the video behind the 'mask' without the mask moving...
That's exactly why I suggested the use of masks that are separate clips and of the Make Transparent filter... I suggest you to check the filters instructions and to try it yourself. In any case it's quite simple to use:
- drag the mask clip (either a generator or an imported custom greyscale still) into the timeline on any track above your clip to be masked - now the mask completely hides the clip below
- drag the Make Transparent filter over the mask clip in the timeline: now the white areas of the mask will become transparent and will show the clip below (look at the canvas to see the result)
- apply any motion, cropping, distortion, etc. to your clip below the mask and the mask will not be affected.
Note that if you want 3 clips together on screen you have to repeat the above steps for each clip: at the end you'll have 3 clips, each with its own mask on top, stacked in 6 tracks of the timeline: the tricky part now is to change the Center, Scale and/or Crop for each clip and its own mask in order to lay them out in the frame as you need. But each clip may have a different mask shape and be modified without affecting its own mask.
Let me know if it works

Replicator as Image Mask?

When I export my movie, an image layer drops out of frames randomly. I'm thinking it has to do with its "Linear Dodge" blend mode and animations going on below it. Is there a more proper way of accomplishing this:
- Replicated shape with a gap between the tiles
- Image visible only where the replicated shapes are (not in the gap areas)
- Generator animation behind the replicator visible only between the replicator tiles (gap areas only)
What's the proper layer stacking and blend modes to achieve this? Thanks!

Here is how to use the Particle Emitter particles as an Image Mask, from a tutorial I just wrote for macProVideo.com/HUB
Blend Mode is not the way to do this.
You can replace "Replicaor" for "Particle Emitter" in this explination easily.
- Import or create background image.
- Import or create image to become the Particle Emitter particles.
- Create the Replicator.
- Right-click the background image and choose Add Image Mask.
- For that image mask in the Inspector, drop the Particle Emitter into its Mask Source well.
