Alpha channel from photoshop changes on import to FCP

I'm new to alpha channels. I have an image, to which I added an alpha channel in Photoshop, which now gives me a cut-out of the image. I imported the psd of this into FCP 5.0.4 (I was not allowed by FCP to import a tiff with an alpha channel.) However, the alpha channel on the clip in FCP has now become the whole rectangle of the image area, not just the mask area as it was in Photoshop, so when selected, the whole image is masked. Changing the alpha type, or reversing it, does not make any improvement. Is there a solution to this?
Many thanks
John

David,
I just had a breakthrough with this. The original file was CMYK. Creating an alpha channel and importing it into FCP gave me the problem. Converting it to RGB first, then creating the alpha channel and importing it, solved the problem. Doh!
Your line "sounds like you didn't create one" gave me the clue. Many thanks.

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.

Alpha channel from Quicktime into AE - broken?

This has been driving me nuts for some time. I am generating an animation w/alpha channel from my 3D software (FormZ.) It creates a proprietary .fan file containing the animation frames, which is then converted to Quicktime. I am using the animation codec, max quality, millions+ colors. When I import the QT file into Aftereffects, I get the alpha channel pop-up - so it apparently recognizes that something is there - but whether I choose straight or premultiplied, I just get black for the alpha channel with jaggy edges.
This is on OSX 10.5.5, QT 7.6, Adobe CS4. I have had the issue dating back a year or two, I had thought it was a bug that would be fixed by now - the same process used to work fine with older versions of AE and QT.
Now - the kicker - when I boot into Windows XP and do the QT (7.5.5) conversion there - then take it back to OSX for import into AE - THE ALPHA CHANNEL WORKS PERFECTLY.
I have talked with FormZ in the past, they recognize and have duplicated the problem. However, it is apparently a Quicktime issue so there is not much they can do about it.
This seems like a pretty fundamental issue that I can't believe it would go uncorrected for so long. Why would the Mac version behave differently from the Windows version? Am I completely missing something in the Mac QT? I have played with the various transparency settings under Movie Properties (QT Pro) - but all I get is a dithered mess when I try to change those settings and bring it into AE. I can't even find much discussion of it - I found a reference to Quicktime 7.1.5 breaking alpha channels, but nothing very specific.

Welcome to the discussions, austinpike.
Normally, QuickTime should work the same on both systems. However, there are some deep differences in how the OS's work that mean the code isn't fully transportable, so there's a chance some things might get missed, or changed, etc.
What you should do is go here.
http://www.apple.com/quicktime/feedback
And enter your details that you specified here. It could very well be that no one has reported this as an issue yet. I know I'd been perturbed by something in QuickTime I thought would just "get fixed" but a few versions after sending my bug, it was finally resolved. Hopefully, sending the feedback may put the wheels into motion to get it resolved for you.

AppleScript copy alpha channel from one document to a second document

I have two documents. One with Alpha Channels, the other with none. I am trying to copy the alpha channels from one document into the second.
When I use the following in PS 6, the action duplicates the channels in the same document, not in the second document. I am using PS 6 with both documents open in tabs. Any help appreciated.
tell application "Adobe Photoshop CS6"
set x to document 1
set y to document 2
set cc to number of channel of current document
repeat with i from 5 to cc
duplicate channel i of x to y
end repeat
end tell

I can now copy-paste text frames and linked graphics from one document to another using snippets, but embedded images still don't work.
If I embed an image from a pdf file it works but not for jpeg images. When I open the new document (for which I placed the snippet) in InDesign, there is a frame (with a dark grey background and a diagonal cross) shown, but no contents. The place() method did not throw an exception. What am I doing wrong?

How do I save a PNG file with an alpha channel in Photoshop CS5?

I have a PNG file created in Photoshop and I need to save it with an alpha channel for web purposes. I tried 'Save for Web & Devices' and selecting the Transparent box. Then, after saving, when I select 'get info' for the file it says there is no alpha channel. I'm stumped I can't seem to create an alpha channel from within Photoshop while I'm editing. Help!

If you save as a 24bit png with transparent checked photoshop will save the png with transparent background (ie alpha transparency). The png will appear transparent in a web browser.

Copying an alpha channel from one comp to another?

I've created a green screen key using Primatte in one comp, and I want to use that same key in another comp, but where the background has since been replaced and rendered out with an effect I want to keep on the foreground subject. I bet it's something simple...
Actually I bet that explanantion's confusing.
Subject X is against green in a video in comp A.
X was extracted using a key and rendered with an effect and a new background to creat video B.
I want to extract subject X from B (and keep the new effect) using the alpha channel created in comp A.
So how do I copy and paste the alpha channel from comp A to a new comp with video B in it?
Cheers!

Pre-compose, use as a matte layer.

Alpha Channels in Photoshop CS4 not working

I'm not an expert at using alpha channels, but I was trying to clip someone from a background. I followed the directions according to a tutorial I found (choose which color channel looks best, then Alt-click on New Channel). My alpha channel always looks black. Anyone else have this problem?

I thought there was a way, using the channels palette, to create an
alpha channel from one of the RGB layers and use levels to blacken out
a background.
Yes there, are two ways - to use the clipboard: copy and paste the RGB layer into the alpha channel - making sure that full color composite view is visible, and the correct layer is highlighted, when you copy - and ONLY the alpha channel is selected in the channels palette when you paste.
Another way, which you may have heard ages ago, is to load the RGB grayscale - command clicking the RGB composite channel. Then create a new alpha channel from this selection- if the channel is the wrong way round invert it (command I)

InDesign CS5 will not import Alpha Channels from images saved in Photoshop CS6

Just searched through the forums to find this thread in the (now-Read Only) Photoshop CS6 Beta forum:
http://forums.adobe.com/message/4310886
Which is exactly the same issue I'm having. I just cropped about a 1000 images with alphas originally created in PS5 and resaved using PS6.
My client still uses CS5 and the images won't recognize the alpha channels in inDesign5.
I see in this thread that it said a fix for older versions of inDesign was being worked on, this was back in April.
Any news on these fixes? (before I open PS5 and resave all these files)

Hi Peter,
The images in question all use alpha channels to mask out the image backgrounds (usually white) in InDesign layouts.
I opened the images in PS6 to crop out excess background (to get file size down) and saved the new files.
When I go to import the images one by one into InDesign 5 (via Cmd-D, Import options ticked) the Alpha Channel pull down menu is greyed out and I'm unable to select the Alpha Channel.
If I open the image in PS5 and resave, I'm then able to access the Alpha channels in ID5... but that's a lot of images to go back through to fix.
I also tried opening the layout in ID6 (where the alpha channels do work) and saving down to the idml format. When opening up in ID5 the alpha channel is no longer recognized and the background of the image that was masked out is now visible.
Cheers,
Alan

How to import an alpha channel from .PSD file?

I have a photoshop file (.psd) with an alpha channel. When I import this file into AE, I do not see the alpha being available or perhaps I don't know how to find it. I've followed this instruction but nothing happens afterwards. Okay, so my question is, when I drop the .psd file into my comp, how or where do I enble the alpha channel?

I am not sure this a bug.
It could be. But note that I can produce an identical case in which this behavior is not a bug.
The thing is, in the world of video applications, Alpha Channel means "fourth channel used to store transparency values".
In Photoshop, it normally means the same thing, but it can also mean "arbitrary channel created and stored for whichever reason the user may want it on the future". Typically, to save a selection so that it can be retrieved later. In fact, you can have many of these arbitrary channels.
So, imagine this scenario:
1. User makes a selection of the outline of the house.
2. Instead of cutting the pixels outside the house, or creating a layer mask, the user goes to the Channels panel and hits the "Save selection as channel" button (or equivalent menu command).
Photoshop creates a fourth channel (or even a fifth or a sixth if there were additional channels already), which is called "Alpha" but the user never did anything to make the information in that channel produce transparency.
If after making the selection, the user would have cutted pixels or created a layer mask, then that operation would be relfected on what we normally consider as Alpha channel.
In this case, what you can do is go to channels pannel, control click the thumbnail so that the channel is loaded as selection, then create a layer mask (Layer > Layer Mask > Current selection) from that selection. That's it.

Best Codec for exporting animations with alpha channel from FCP timeline

Whats the best codec for exporting animations (hopefully using loseless compression) that will retain alpha channel, and use the current sequence settings for fps and size?
Currently Im exporting image sequences, but I'd prefer a wrapper.. I don't know much about the 'Animation' export codec.. I did notice that set to current size had some funky value of 753x450 or something.. instead of my current project size of 1920x1080...
Anyhow.. Just seeing what others are doing..
basically Im reading out some titles that I'll end up dropping over video later.. but since they render out so slowly (**** lower 3rds is slow) Im trying to get a jump on the process..
Tx..

PNG should do it. I think PNG is lossless (that's what they say, anyway). But realistically, if you use PNG, Animation, or JPG2000 set on highest quality, I'd dare you to tell a difference.
I use PNG because it's supposedly lossless, renders twice as fast as Animation in a FCP timeline, and is usually about half the size.
If you use "Export Using Quicktime Conversion", you will need to check all of the settings manually to make sure they match your sequence settings. This is always true, no matter what codec you use.
If that sounds risky, your other option is to go into your sequence settings and change the codec to the one you want to render to (this will probably turn your whole timeline red), and then choose Export -> Quicktime movie.

How come AE cannot interpret Alpha Channel from ProRes4444 ?

Hi there,
I exported a video clip using Final Cut Pro X with alpha channel using the ProRes4444 codec.
I have tested his alpha channel works & it works in FInal Cut Pro X when I import it back to Final Cut Pro X to test it.
However, when I bring this file to After Effects CS5, it cannot recognize the alpha channel because the transparent part are all in solid black.
How do I make AE interpret the ProRes4444 file as transparent with alpha channel ?
Thanks

Q2. I am using AE CS5. Is it bcos you are using AE CS5.5 that you never have problem with ProRes4444 ?
Q1. This is part of the basics. Select the file you want to interpret in the Project Panel then either right click or go to the menu File>Interpret Footage>Main or use the keyboard shortcut Alt/Option + Ctrl/Cmnd + G
Q2. Nope... It's always worked. There were some gamma problems for a while, and a few other bugs here and there with ProRez, but if you're Mac is up to date you should have no problems with the alpha channel.
Thanks Rick for your help, I really appreciate it as I am not quite familiar with AE.
Q1. I did the steps you taught me & a new screen pop out. But under the "Main Options" tab, the section under Alpha, there are 4 choices (Ignore, Straight-Unmatted, Premutliplied-Matted with color, Invert Alpha). But all these was all greyed out. Any idea why ?
Q2. I am using Mac & I just checked my AE CS5 is Version 10.0. I am a student and i bought the Student Edition. Student Edition not allowed to update, right ?
Thanks

Alpha Channel in Photoshop for iWeb instant Alpha?

Hi,
Recently i wish to Make a Picture's Background to transperence.
I try to use a ODD color (green screen's GREEN) as background color so that it'll be easy to delete the background when apply the instant alpha function...but i relize that it doesn't really make sense at all...Most of the parts doesn't process well...
Question:~
+ What s'ld i do in Photoshop before i bring the picture file into iWeb for instant alpha?Alpha Channel and save as .psd?
+ Do any other useful way to solve the issue above?
Thanks!!

Here's what I do:
1 - open the file, double click on the background layer in the Layer pane to unlock it and add a second layer below the original layer.
2 - using your tool of choice delete the background you want removed. If the background is a single color I use the Magic Wand tool. You may have to work with the Tolerence number if there's any gradiants. Other wise I use the Quick Selection tool (again you may have to set the Tolerence level)
3 - When he background is removed you then use the File->Save for Web and Devices option.
4 - in the next window select PNG8 under Preset and check the Transparency box. Colors is set to 256, Dither at 200% and Web Snap 0% (these are all the defaults the first time I used it).
5 - The background should show transparent. It it doesn't click on the color that you want transparent in the Color Table and then click on the far left box in the toolbar directly below the color chart. You can add additional colors if desired.
6 - Save and you're done.

Making a alpha channel in photoshop elements 5.0

hello so I am making this spray or icon I guess you could call it for counter strike source which is a game I play. But I want to make it so that it has no background and apparently I have been told that I need to make an alpha channel so that I can do that. But every tutorial I can find on the internet is for previous versions which have a channel tab in the layers tab.
How ever elements 5.0 does not that have. Can someone help me with this it is driving me crazy lol I have tried just saving it as a targa file in 32 bit nut it still had that white background :(

Colin 1 and 2, thanks. I enjoy your web sites and learn alot from them and your comments here. I am using selections here mostly as cutouts, I'm not sure of my terminology in this forum yet. I never used photo shop and would not know an alpha channel if it bite me. I have spent much time making a selection/cutout and want to save it. I thought save selection would send it some place like copy command saves in note pad. I now believe I have to save the image with it's multiple layers if I want to use that selection/cutout in another image.
Only if you want to do the same selection into other images at other times do you need to save the selection. Then just drag and drop it across. Colin#2
