Layer Mask/Alpha Channel. Visual bug when moving or transforming

Open test file.
Add solid color Adjustment Layer.
Paint a big "X" on its Layer Mask.
Option(alt)+click on the mask icon to see its Alpha Channel.
Now select Move tool and move mask around.
Alpha channel does not display properly when moved or transformed.

Right Jeanne, should have realized.
A good workaround for this, if you want to see the mask as you move or transform, is to just hit the backslash key to see the rubylith of the alpha channel. That displays correctly.

Is there a way to control brush parameters by special layer mask or channel?

Is there a way to control brush parameters by special layer mask or channel? Maybe there is some plug-in for mask controlled brushes? Or channel controlled brushes?

You are not understanding how masks work. If you look closely at the first six brush tip options in the brush panel, either of the first two will give you a fixed size stroke regardless of pen pressure
To control the appearance, or masking of specific colours, you would use a Hue/Saturation adjustment layer, and use the RGB drop down to select the colour you want to affect. Without know _exactly_ what you are trying to achieve, no one can do more than guess, but from what you have written so far, I suspect you are going to be out of luck.
What tablet are you using? And you did not answer my question about what version of Photoshop? You need to be a _lot_ more specific about what you want to do if you want keep my fast failing interest in this thread.

LPX: Environment-mixer layer bug when moving channel strips

Please test if you experience the same bug on your system: Open a LP9 song in LPX - go to Environment / Mixer layer - move a few channel strips a little. I tested on two computers and the channel strips jump to random locations. It doesn't happen with all of them right away, so you might have to move a few of them initially. But eventually (after a minute max) most if not all exhibit this behavior.
I also had this happen in new LPX songs.
Please let me know if you are able to reproduce this.

Moving a layer's alpha channel into layer mask

(CS3)
I have a raster layer that has some semi-transparent pixels. I'd like to make the layer itself fully opaque, and move the contents of its alpha channel into a layer mask. How would I go about doing this? (If possible, merging the alpha channel with what I have already placed into the layer mask.)
Thanks!

Copy the alpha channel into your clipboard, then paste it into the mask. To paste into a layer's mask, alt click the mask to make the mask the focus then ctrl v to paste. To remove focus, alt click on the mask again or click on another layer. As to how to mix the two, you could probably do it using calculations.

I'm creating a lower third in Motion and importing into FCP X, but the alpha channel is gone when I import into FCP. What am I doing wring?

I'm trying to export from Motion 5 with an alpha channel, but in FCP X the alpha is gone. What do I do?

if you're exporting video animation out of Motion and you need transparency, then you need to make sure that the codec used is ProRes 4444. There are no other options. From the Share > Export dialog, the default Export option is usually "Same as Source." In Motion, that *should* be PR4x4. You can double check that setting by clicking the summary button and reading the last line.
You also need to make sure under the Render section that Color + Alpha is selected (that should also be the default setting.)
However, most of all, you're really wasting your time going about it this way. If you started a Title project in Motion, all you have to do is Save and give the project a Name; pick a category or create a new one. In FCPX, in the Titles browser, look for the category you used and find the project name and drag it onto the storyline.
You have the option of picking parameters in your motion project that you can "publish" to FCPX (things like the lower third background color, text color, positioning, etc... almost every parameter is publishable to FCPX allowing you to customize the project *inside* FCPX.) Any parameter you publish in Motion will be in the Title Inspector in FCPX. You do not have to "bake" your lower third in Motion before using it in FCPX. You can pretty much turn your project into an FCPX plugin.
If you didn't start a Title project, you can still build your lower third as an FCPX Generator. Go to the File menu and Publish Template... In the dialog box, make sure you check Publish As Final Cut Generator. Give the project a Name and select a category (you'll need to wait a few seconds until the Categories update to the FCPX categories...) You can create a custom category if you like and save the project. In FCPX, instead of the Titles browser, look for your template/plugin in the Generators > WhateverCategory > YourLowerThird.

Extract layer with alpha channel or with whole layer size?

First of all.Sorry about my English.But I'll try my best to describe what I mean.
The text with transform:
The extract window of text:
Is any possible make the extract given whold layer size result ?
What I except:

But that's a lot of layer i need to extract
Almost like ... 21 layers and i need another scaled level "x/2" "x/4"
21 * 4 = 84 I must do 84 save as. thats not good.

How copy an alpha channel mask to an adjustment layer?

I can copy an alpha channel mask to an image layer by Ctrl+Clicking the alpha channel then clicking the Add Layer Mask icon in Photoshop CC but this does not work for an adjustment layer. How can I copy the mask from an alpha channel to the layer mask for an adjustment layer? Thanks.

I am using Photoshop CC as I stated in my question. All updates have been installed.
I am running on Win 7 Pro 64 bit with all updates installed.
I am editing a photograph.
I have an alpha channel with a grey scale mask.
If I Ctrl+Click the alpha channel then click the Add Layer Mask button to add a layer mask to an image layer the alpha channel mask is added to the image layer.
If I delete the layer mask from an adjustment layer and follow the same steps a solid white mas is added to the adjustment layer.
Several others in the camera club I belong to have tried this with the same result so the problem is not unique to my system.
Hope this helps.

Procedure for Integrating Alpha Channel when saving as .dds file

Hello,
I'll try to keep this brief but that may be tough...
One project I use Photoshop CS4 for is painting aircraft used with Microsoft Flight Simulator X (FSX). Here is some background for folks who aren't familiar with this.
Each aircraft is downloaded as a "Paint Kit". The kits look much like the "trees" that plastic aircraft model kit pieces come attached to (see picture below).
I paint and add layers onto the kit until the aircraft resembles the design I chose. The paint kit includes a background, base parts usually in white, and an assortment of layers adding physical wear, shading, lines and rivets you see on actual aircraft.
Additionally, the kit includes an RGB Alpha Channel and Specular Maps. In this application, the Alpha channel provides the reflectivity or gloss on the aircraft paint. The Specular maps provide a sheen much like the subtle reflections you see from a metal flake paint job when the sun hits it directly.
Once all painting and manipulation is complete, the kit is "cut" into specific sizes. Once the kit is cut, each section is saved as a DDS file using NVidia tools. The resulting DDS files are placed into folders within the main FSX program folder. The FSX program "assembles" the sections and processes the different layers and channels resulting in aircraft that are incredibly detailed and realistic.
My problem is I don't know how to properly integrate and preserve the Alpha channel during the "Flatten Image" and when saving the file as a dds file. As you can see in the "Layers" section in the picture, the Alpha channel is already made. I just don't know what to do with it to preserve it and ensure the reflectivity it provides is visible in the final product.
Any help is appreciated - what I need to know isn't what the alpha does, but how to properly integrate it into the final product. I've searched for this info for the last several days, but I've had no luck in finding specific information on how to do that. I believe it's one of those procedures that is so simple, everyone knows how to do it. I guess I'm the only idiot on the planet that doesn't know how... .
The paint kit can be downloaded at http://library.flight1.net/wp-content/plugins/download-monitor/download.php?id=1467 if you need it to answer my question or if you're just curious about it.
Thanks for your time and consideration.
Mark

I know nothing about Nvidia DDS file format or 3D. From you screen capture you have no Alpha Channel. You do have a normal layer named Alpha Channel with its visibility turn off. Why are you flatting ? When I use Save As and use the file type pull-down and select DDS format to save I get the Nvidia DDS save Dialog that I do not know how to use or understand the buttons options or pull-down menu items. The file instruction and its background make no does not seem to match up with the parts.
I think you have to read the documentation for the Nvidia DDS plug-in. and the normal map plug-in https://developer.nvidia.com/nvidia-texture-tools-adobe-photoshop

Export PNG images with alpha channel from flash

Hi,
I have this FLA with animation and when played, the animation has alpha channel. I can’t understand why when I look in the library I see the frames without the alpha channel and also when I try to export/extract the image again the image don’t have alpha channel.
How is it that in flash this image has alpha channel and how to get it out like that into PNG?
Here is the link to download the FLA:
http://download759.mediafire.com/nb749r29220g/e0636ab0ru6ouoa/Untitled-1.fla

"when played, the animation has alpha channel"
how are you playing the animation? control/enter in Flash, Publishing to a Web page or what?
How can you tell that the animation has the alpha channel? What exactly are you seeing?
What is the aniimation? a series of images, one image moving? Are teweens imvolved?
" when I try to export/extract the image again the image don’t have alpha channel"
How are you exporting the image? is it a single image? or a series of frames that makes up an animation?
What was the file format of the original image? you brought that image into Flash and animated it? Now you want to export as a .png with transparency?
Have you ever tried to export a simple .png before so that you see and understand the dialog box that pops up during export? are you chosing "24 bit with alpha channel" in the "Colors" choice?
For those of us who may not want to download your file, please provide a more detailed describtion of everything related to this question.

I can't get Layer Masks to work with PScc but works fine with CS6

When I create a layer mask it shows up properly but doesn't work at all. I have the correct layer selected and I'm painting in black (and nothing happens in white either) and there is no problem when doing exactly the same thing with CS6 so I thought there might be a difference in my settings but I can't see any. My masks are NOT disabled in properties. Nothing shows up on the image nor on the mask. I can however, use the eraser tool as normal. Any ideas?
Thanks!

PLease could you help me too. I have been onto support through several emails and online helps and they do not understand the problem correctly and have not resolved it. I have photoshopcc 2014. If I click on add layer mask icon I get a white thumbnail. That seems ok. I then select a brush - set to normal etc. all ok. Then I attempt to either brush in or out on my photo to reveal or hide bits of layer below and it no longer works.
Weirdly, I noticed it was not selected in channels. So I checked the layer mask in channels and then back in layers it works except now it works by painting on a rubylith (which it did not do before 2014 version) then when I am done if I click apply mask everything works ok and it is done. It just does not work unless I select in channels.
This also happens if I apply an adjustment layer. The adjustment comes into the thumbnails with a mask and the mask is unselected in channels, I have to select and it paints a ruby lith.
If I go to layers in the menu however and select layer mask hide all or reveal all then select my brush it works fine and as it normally did before.
I have tried re installing etc. and every bit of normal advice but nothing works. Can you help or do you know anyone who can. As I am desperate here is my email: [email protected]
thank you

Brush Tool is not working with Layer Mask

Working with Windows platform, using Photoshop CS4, Brush Tool is not working with Layer Mask, how can I resolve this challenge?

Also, do you have any Selections active - maybe hidden?
When you have your Layer Mask's Channel active, do your Colors change to black and white?
Good luck,

Using video with alpha channel

I purchased a video clip from istock, the video clip is an .mov and has a alpha channel included. The video clip is santa clause over a black background and tagged at the end is a white solid of the video (I assume this is the alpha channel) How do I use the alpha channel to help key out the vidoe clip that I need. here is a link to the actual video clip I purchased. http://www.istockphoto.com/stock-video-11011749-santa-claus-with-alpha-channel-ntsc.php
Thanks Ja

As Szalam said, the b/w image can be used as a luma matte.
Also check if the actual piece of footage has an embedded alpha channel, i.e when you import it AE should know there is an alpha channel and let you know in the top of the project window when you select the element (or "interpret footage").
Alternatively just drag the footage to a comp and enable the checkerboard background to see if there is transparency. These three approaches are the same...just different ways of finding out about the alpha channel.

How do I add a new alpha channel in pse9?

where would I find the channel tab for pse3? I would like to use a black, white gradient and the lens blur to give a picture depth. I would like to make things in the background look farther away with a gradual blending effect of the lese blur. thank you in advance!

You make a selection, then save it as a new selection.
However, I'm not at all clear as to why you need to do this. For what you described in your first post, grouped/clipped layers would work better.
I myself only make alpha channels per se when other programs require them. (If you load the saved selection, then save the file with the selection active, it will be seen as an alpha channel by many programs).

Enabling alpha channel for PNG file

I want to include a logo with a transparent background in an iMovie video, but when I import a PNG file with a transparent background, the background turns black. I think this is because the PNG needs to have alpha channel enabled.
When I attempt to save the file as a new version, the "alpha channel" option is greyed out. How can I save the file with the alpha channel enabled?

Hi,
You might want to visit this thread for more info on iMovie's handling of transparency:
http://discussions.apple.com/thread.jspa?messageID=13123097
It sounds like iMovie converts the PNG to a JPG internally for some cases (fit, crop, Ken Burns effect).

Exporting Quicktime with alpha channel

Hi,
I'm currently editing a piece full of talking heads that will eventually be converted to flash to be used on a website. The heads were shot on DVCPRO 50 on green screen and keyed using advant edge. I am using DVCPRO 50 timelines. I need to export quicktime movies including the aplha channel so that the resulting flash movies (which are to be encoded by another company) appear without the background on the website. When I look at my files on the screen they appear over the checkerboard background. I exported using animation codec set to million of colors +. Just as a test to see if that would work I encoded a flash movie from the quicktime file using the new Flash 8 "encode alpha channel" option. When I viewed the file it was over a black background. As a further check I imported the quicktime movie I had made into a new sequence set to animation millions +. It also appeared over a black background. Did I lose my alpha channel somehow? When I view the format info on the quicktime file, it lists the alpha channel as being "straight", which I assume means that an alpha channel is present. Can anyone help me out?
G5 Quad PPC Mac OS X (10.4.6) 2 GB Ram, Aja Card

OK I changed the sequence settings to animation millions + (as they were previously set to DVCPRO 50). When I did this all of the files became unrendered, which was the desired effect. I exported a 5 second piece animation millions +. It had a black background in quicktime, but when I imported the quicktime movie into flash encoder my subject appeared over the white default flash background. We have a winner! Now my only problem lies in export times. It took nearly 8 minutes on my quad to export that 5 second clip, and I have 34 clips that are at least 30 seconds apiece. I think I'm best off setting uyp a batch export to run over the weekend. Thanks again for all the help guys! I would have never figured out that the files had to remain unrendered in order for this to work.
