• Problem with cs6 and alpha channel AND updates...

  I converted just of CS5 at CS6.  Files that work in CS5 are no longer works.  CS6 seems to skip a lot of alpha channels.

  I tried to re - import a film - image (ignore alpha offshore) interpretation and update to Cs6.01, but the update will fail with Error Code: U44M1I200.

• Problem with cs6 and alpha channel

  Help

  I upgraded from 5.0 to 6.0 CS cs Production.  I have several commercails with links to AE.mov files with alpha (codec animation million +).  I did this for more than 10 years, so this should be pretty basic.

  Cs6.0 documents do not take into account of alpha.  CS5.0 sees the fine.  I re - importing .mov files, reinterpreted the files (ignore alpha offshore) and rebooted the machine.

  I tried to install the 6.01 update, and the update could not be installed.

  Any have any ideas on body CS6.0 don't know why alpha in my publishing channels?  iMac i7, 3.4 12 GB of ram, OSX 10.7.4.

• I installed on a computer with lightroom lightroom cc 4.  When I start lightroom cc he wants to combine old images and I want to have this new version without old images.

  Don't want old lightroom 4 images imported again lightroom cc

  You can use the menu file-> new catalog command; or simply say Lightroom CC do not update the catalogue Lightroom 4.

  If I could give some advice, normally the best procedure is to have all your photos in a single catalog, rather than starting a new catalog to an arbitrary point in time when you buy a new version of Lightroom. A catalog has many advantages, including the ability to find and make use of all your photos and almost no disadvantages. Several catalogs average you can't find and make use of a few photos that are in your new catalog and a few photos that are in your old catalog.

• Create alpha channels that are premultiplied with png and other formats

  Hello

  I am in the process of manufacturing assets for Unity3D engine and I do the transparent PNG with alpha channels that are premultiplied with black. My questions:

  1. To this day I use superPNG plugin to add an alpha channel, because it was really hard to find the opportunity to do this in the menu Save under... . Today very very accidentally, I found Export-> video renderer where I choose PNG and premultiplication. I do something wrong or is this the right way to Photoshop to export png via the video function? It seems really hidden!
  2. I can do the same thing for TIFF, PICT (I guess no pict for me because its pure mac?) and tga with a layer of black format and checking box of Alpha channels, but its somehow greyed out for PNG? Why is this?

  I think its a kind of contradiction, or am I missing something?

  Thank you for your time,

  Peter

  PNG, standard format, does not support alpha channels, only a single transparency channel.

  PNG allows only 4 channels, and that the fourth channel is transparency.

  Some video software packages use PNG and treat as premultiplied, even though the spec file says that it must be of the right color.

  You could save yourself a lot of trouble by jumping alpha channels simply recording your PNG after step 1.

  Yes, if you messed with the color values and alpha channel you might have ended up with a file that looks like values premultiplied (since you wrote all the zeros in the layer of color, but has no need of).

• Combination of alpha channel selection

  I made 6 individual selections on a photo and recorded each selection.  I have 6 alpha channels representing selections.  I have creative cloud, using a PC with Windows & and try to combine the 6 selections in one.  When I go to select > load selection, I select one alpha channels and make my new selection.  The marching ants that appear on my image.  But when I try to add 5 other alpha channels (select > load selection, choose the channel and choose Add to the selection, click OK), nothing happens.  Mobile dotted have not been added to the first selection.  Am I missing a step, something wrong, or do I have some sort of bug in the program?

  Try this: after loading of Alpha One as a new selection, load the others using subtract from selection.

• combining alpha channels?

  Miss me something really obvious here, but what is?

  
  

  
  

  I want to have a topic casting shadow on a background of moving clouds. Here's the clip up to now using a method that does not work well enough:

  
  

  
  

  
  

  
  

  The shadow does not work on the darker parts of the cloud. This really isn't so much of a prob in 2D, but it is a stereo 3D project and have the shadows disappear intermittently seems odd.

  
  

  
  

  For example, to create a shadow that I can then insert between the two Images, I need to combine two video alpha channels (the one created using green as a key, the other the blue of the sky).

  
  

  
  

  How do I do that? I bet it's really obvious!

  Currently using CS5

  Use effect channel juggler or things like change the channel to expose several channels and merge them differently. Or you could use a demo that has duplicates of your stuff and then use matte and stencil blending modes. It's really just a matter of using each other and combining them intelligently...

• keep an a 1 bit image alpha channel

  Greetings!

  I do a lot of pre-press and the restoration work for printing, mostly working with equipment that requires released as a 1 bit image - very fine line work and mechanical tones that will break or cause the moire if printed with dithering.

  For this reason, when you work with commercial printers I've out usually images with superior typical resolutions - 1 bit 2400 ppi files, i.e. the same their imagesetter resolution works.

  I have a request current a client that involves, at their request, to place images with transparency in Indesign rather than manipulate raster images in Photoshop and just out of the final 1 bit image and placing in Indesign.

  So, I was playing with alpha channels to try to find a solution to this. Is there any image format that will support two channels - one for a piece of mono ppi (1 bit) 2400 line drawings and the other for an alpha channel that will be used to hit transparent sections in Indesign after the fact? Is this possible?

  I COULD simply threshold - adjust my image to make pseudo-1-bit and then place the file in Indesign. But it's a big waste of space (the file resulting in dozens of times larger) AND it makes it more likely that someone will accidentally mixed the image during the RIP to print, thus defeating the objective of providing a high resolution 1-bit image in the first place.

  Please, please, anyone out there have any advice for me?

  Best,

  Well, the next day-

  I read some more about how little coding works on different file formats. There is no place for the information/alpha channel for transparency on image 1 bit because, well, there is only a single bit, i.e. two States - on (ink) or disable (paper). If the shutdown state is managed like a white by Indesign, or the stop State is managed as paper and is presented in a transparent manner.

  So what I really need, is a 2-bit image format. A PNG. While there are four States - on (ink), (off-white) and another way for transparency.

  So I have 'threshold' converted by alpha channel and my channel of the image, then to export--> save for Web (inheritance) and selected 4 color PNG. Voila! Perfect bitmap 1-bit with transparency.

  Now, if he is a pretty good solution for my printer and their Raster image processor, we get to see!

• How to add an image to the alpha channels

  I want to add an image in black and white in this layer alpha https://gyazo.com/f3507eaa453f720bf7257ed9f7725404

  But I can't get a picture on it. Any help appreciated.

  1) press A ctrl or cmd - A on a Mac to select the content of your layer or simply select all from the menu bar.

  2 in your layers panel, select your alpha channel and then issue - special paste - paste in Place

  The contents of the layer doesn't have to be black and white as it will be converted to grayscale, but depends on the type of mask you're trying to do.

  Hope that helps

• I need to create combinations of text and images for the web. How to do this in elements or do I need Photoshop for this feature?

  You can do in PSE.

  1. Do the math to see how much space you'll need on your canvas to the image and text.
  2. Navigate to the file queue > new.blank. Enter the width & height, background color, resolution 72 px / in. It is your canvas, and in the layers palette will be the background layer.
  3. Copy and paste the image. It turns on a separate layer
  4. Activate the tool move, position the image and resize if necessary
  5. Activate the text tool, and then type your text. It will be on a separate so layer
  6. Position the text.
  7. Flatten layers and go to file > save for web. I'm usually on the long side about 800 px. Don't forget to check "constrain proportions". Adjust the quality slider to suit. You will probably want the type of JPEG file for web work.

• How to use a black and white AVI as an alpha channel?

  Brand new first CC 2015 user here (actually just a user first brand new total), with what is probably a very simple question:

  How can I take a clip in black and white and get the Premiere Pro to use as a mask in alpha channel?

  Basically, I got three items I want to composite together, each of them their own separate AVI:

  (1) a coin of spinning

  (2) a silhouette of the spinning coin

  (3) a movement background

  The animations of the rotation of the piece were made by Bryce 7.1, if this can help, a program that does not know how to incorporate animations alpha channel masks.  I call the "silhouette" as such because it is a completely white room version, turning on a totally black background - perfect for use as an alpha channel, but without the alpha channel information incorporated.  And no matter what I do, I'm not the first to recognize it as such.  Any help would be appreciated.

  Put the background on the V1.

  Thread the room spinning V2, directly above him.

  Put the Silhouette of the coin spinning on V3, just above (and in sync with) V2.

  Go to the control panel effects and go to Video Effects > Keying and select the overlay Cache Track effect. Drag it to and apply it to the room turns on V2.

  A once applied, click the clip on V2 to select and go in the effect controls panel.

  Click the triangle next to the overlay track matte value using Composite matte Luma and the Matte of Video 3. Check the box opposite if necessary to invert the matte.

• No conservation of alpha channels when using Image Processor Dr.Brown Pro.

  Version: Photoshop CS5

  Platform: PC

  Tool/Script: Dr.Brown Image Pro processor

  Question:

  When you use this tool to save the .psd or .tga as .tga files files, .tga file does not retain the alpha channel...  Which means that the source file has an alpha channel works, but it is not present in the file generated by Image Processor Pro.  I have been by ticking the 'Alpha channel' on the interface of the IPP and tried various permutations of the other settings (I of course fully understand).  I don't know what else to try, so I hope someone here can offer some insight.

  Context:

  I develop a game to a Publisher that requires the .tga file format (must be 32 bits/pixel) for images independently.  I created all the .psd and files later .tga I need, but it turns out that given the amount of image files, I need to resize to reduce the overall size of the game (and the alpha channel must be maintained, in order to facilitate the transparency of the image).  Since there are hundreds of images to perform this task to, I'd really like to avoid do manually, because I left the ~ 1 week before my deadline for the demo and want to focus on other aspects of the game.

  Thanks for reading, any help is greatly appreciated.

  Now, I've added an if statement around line 3805 see if it works for you...

  case "tga": {}

  saveOpts.alphaChannels = toBoolean (fsOpts.tgaAlphaChannels);

  If (saveOpts.alphaChannels) {saveOpts.resolution = TargaBitsPerPixels.THIRTYTWO ;}

  saveOpts.rleCompression = toBoolean (fsOpts.tgaRLECompression);

  saveOpts._flatten = true;

  break;

• Bad Alpha channels and different levels of opacity in CS6

  I try to use a low 3rd stock animated and noticed that if I put it on any video clip, the alpha channel has not been completely transparent, but if I put it right on the timeline by itself, it went well.  It is very sensitive at the beginning and end of the clip, because it comes out making it unusable.  It looks the same when I go out.  I use H.264 with HD 720 p 29.97 preset

  On what I assume is a tied note, opacities in my titles look the same on the timeline as they do when I'm changing them.  Really noticeable with the sample black on black below...

  It renders as it appears on the timeline, which is in fact them incorrect. 90% should be much darker than that.

  In addition, it does when I use SD (avi, mov and mpg2 similar) images on a HD timeline.  When previewing, it does only when in pause, but it makes this way unless I have crops...

• Image resizing loses alpha channel

  If I open a file with an alpha channel .psd and resize it via the size of the Image to a smaller version and then save it again, the alpha channel is no longer detected in the new .psd file. I tried to delete the alpha channel and recreate but it just seems not recognized as having the alpha transparency when I open it in other software (for example, an excerpt on OS X). Can someone test this (Note: I'm using CS5) and tell me if they you encounter the same problem? It is specifically only passes through a resizing using the size of the Image and not by the size of the canvas.

  Ah Ah! I solved it.

  I forgot that if the sum of the image layer contains even a tiny part of the transparency, it will use for transparency rather than the alpha channel information. In this case, due to resizing the background layer must have a transparent pixel slightly somewhere on the edge. Fill the entire layer of bg correctly done.

• Images added to the timeline lost their alpha channel

  Hello

  I use first elements 11.0 and added a few png-imags chronology (in another channel the film imported). Each image has a completely opaque pixels and a part with completely transparent pixels. Initially, he appeared fine exactly as I wanted it. But when I added the fourth table, or so, all transparent pixels in black images.

  Images look exactly the same source. I tried to save their new with Photoshop and Paint.NET. I tried to delete a photo and add it again. I tried the first Elements of closing and opening it again. Somehow, nothing worked.

  I checked him 'interpret' the film - window and there is no check mark in front of 'Ignore Alpha Channel' for one of the images.

  I hope someone here can help me ;-).

  Thank you

  Why workded the first several of PNG, but has stopped working, is a mystery to me. The only thing I can think of would be if the pixel x pixel size of those of PNG is large, there may be a problem of resources, when enough are added to the timeline. What are pixel x pixel size of PNG?

  The film and all the images have a resolution of 1920 x 1080. I use Windows 7 Professional x 64 with 8 GB of RAM on an SSD. All project files are found on my HARD drive (internal).

  In the meantime, it is good that you have the solution to workaround to use PSD with transparency, to get your project done, but I am surprised by the behavior of your exposed PNG. A riddle for me.

  That's what I did: I opened the png files in Photoshop CS 6 and saved once again that the psd files. Then, I used 'Replace the sequences' in Premiere Elements to swap files png to psd files. It did not work, the transparent pixels in fact everything went black.

  I wrote that I had success with a new psd file - not with the images I actually wanted to use.

  I don't really know why, but I had to recreate the images from scratch again once (Fortunately, it wasn't that difficult or time-consuming). I saved them as png again files (because I do not really see any reason why that should not work) and imported. This time it worked as it was supposed to. But I can assure you that the new images had exactly the same as the 'old' pixel data.

  I guess it was some cache error. I said not a part of the story, because I thought it was irrelevant. When I had five of my pictures working properly, I used a png on the source files compressor (I had a backup of them). It compresses a third of the original size - but also replaced the transparent pixels to whites (must have used the wrong settings or so). Premiere Elements noticed the changed files and show them in the project now. I copied the backup files to the wrong files and now the files returned to their original state in Premiere Elements. The problem started when I added the following image to the project.

  I managed to finish the small project as planned, but I still wonder about this strange thing. Thanks for your reply though. How to mark this issue as resolved? That I have to take a "good response" (but then I don't know which one to choose)?
