.png animation files... how to import keeping alpha channel please!

My graphics man has buit me a animation on white swirly things on his system
and given me them as sequential files.
On gfx without alpha I open then in quicktime, open a sequential files then export to dv.
Now of course dv will not keep alpha channels so any help on how to take this animation alpha .png and get it into my fcp time line would be much appreciated,
regards

Apple Animation is a high quality video codec that can support an alpha channel.
While there are other formats that also support alpha channel, Apple Animation is the codec of choice on the Mac because it lets us transfer files between different software packages without any hassle.
For instance, you could export a 3D scene from Maya, manipulate it further in After Effects then drop it into the FCP Timeline, all without converting it to something else at each stage.

  • 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.

  • How to Validate Transparent Alpha Channel in .mov File?

    I'm trying to create transparent flv files to embed in Abobe Captivate.
    I shot and keyed some test greenscreen (yes, I have the checkerboard in the canvas) and have tried exporting it a number of ways (rendered/unrendered, recompressed all frames/not, etc, etc) and converted it to flv a number of ways (change mov to flv, encoding software), but when I embed it and play it back I have a black background.
    How can I validate that my .mov file contains the alpha channel and it's transparent?
    Second, when the .mov is correct, will changing .mov to .flv keep the transparent alpha channel or do I need us encoding software with a codec that supports transparent alpha, e.g., On2 V6?
    I'm pulling my hair out here...

    Hi - To validate your exported (Animation codec, Millions of Colors+ ?) Qt movie has the alpha quickly, re-import the exported movie back into FCP and load it to the viewer with the viewer set to display checkerboard as a background.
    Can't help with the rest.

    You've successfully rendered the alpha channel. Alpha information is not displayed as expected in some players. IN QT Player, your alpha is transparent but the player has no background so it defaults to black. Check the playback operations and settings/prefs for QT Player, there may be a way to tell it to show alpha information.

  • LR import with alpha channel

    <Lightroom novice> Can I import a tif image with a alpha channel in it? It seems as though LR will accept the image and allow development but when I export it as tif or psd it goes out as RGB only - the alpha channel is gone. I don't really "need" to do anything with this channel in LR but I can't have it disappear either. Maybe a import/export setting issue - I hope so...

    TLL... wrote:
    "All file "edits" are kept in LR's catalog, which should be backed up along with the unmodified "original" files."
    OK, got that too. We probably won't save this once the exported images are approved and backed up.
    It sounds like you don't need LR's database tools for organizing, adding metadata, or the various Export modules. You could still use LR to expedite Development editing of the RGB image. One possible solution is to Export the LR edited RGB images full size to a separate folder with the same bit depth and colorspace as the original files. Then use a PS Script to Batch Merge the LR export image to a new layer in the original file, something similar to this one:
    http://forums.adobe.com/thread/546727
    This way you still have the original RGB image backed up as a layer, which can also be unselected in the merge script.
    TLL... wrote:
    "At a later date the Alpha Channel information can be applied "non-destructively" in PS using editing layers to "blend" the IR image data."
    This is where I'm getting lost. Are you talking about stripping the 'original' alpha channel from the pre-LR image and inserting it into the LR processed RGB image via PS batch/script? That's my thinking as an one approach.
    "These PS modified files can be re-opened in LR and will now show the applied Alpha channel editing layers. Make any further edits you desire in LR and use the most appropriate LR module to "tailor" the output for your specific usage."
    No they won't, or do these steps involve only psd files w/alpha channels? The alpha channel (IR data) is still ignored by LR, I have no way to even just keep that information once inside LR nor can I "taylor" a way to save an image with 4 channels of color information inside LR.
    I have no idea what you will be doing with the Alpha channel IR image data, but I was suggesting to convert the Alpha channel to a layer mask in PS with 'Blending.' This leaves the Alpha channel as a backup of the IR data. Here's a simulated example using a an IR layer mask I created using LR's B&W IR Develop preset:
    You can use PS actions with the Batch processor and/or build scripts to do just about anything. In LR you can create Develop presets to apply adjustments across 1,000s of images with a couple of mouse clicks, but no Actions or scripting capability. Like I said, PS & LR are complimentary, but different. I'm not sure which processing methodology is best for your image "end-use" but I hope this gives you some more ideas.

  • What codec to convert .MXF and MP4 files into to use with alpha channels in Ae and Pr CS6?

    When I import .mxf File, shot on a Canon C300, into after effects, the alpha channel options are greyed out, when I look in, interpret footage, main. This also is the case importing .MP4 files, shot on a Gopro hero 3. I used to use final cut and using compressor convert the files to pro res 4444 or 422. What's my new workflow for preparing files with alpha channels to use in After Effect and Premiere and do I use Media Encoder to do it?

    When I import .mxf File, shot on a Canon C300, into after effects, the alpha channel options are greyed out, when I look in, interpret footage, main. This also is the case importing .MP4 files, shot on a Gopro hero 3.
    Better question: Where do you expect that Alpha channel to come from and contain any useful info for transparency? You're making a fuss over a non-issue. Unless you apply keying or other methods of creating transparency, even if there were an Alpha channel it would be fully opaque and then what's the point?

  • How to use the alpha channel

    I am using the video editing software "Magix Video deluxe 2008 Pro". Is it correct that after buying Quicktime Pro I can use all features from the Pro version via the export window of my video editing software (which is already offering me Quicktime export with the free QT-version)?
    I have a movie made with greenscreen and in my video editing software I have already seperated the person in front from the greenscreen. Now, how do I tell Quicktime, which parts should be transparent, so that Quicktime "knows" what information to write in the alpha channel?
    Thanks a lot!
    Nils

    I don't know about the software you used. If it made the "alpha" channel then you can enable it in QuickTime Pro by following these steps:
    Open the file and then open the Movie Properties window.
    Highlight the "Video" track and click the Visual Settings tab.
    In the lower left corner is a pull down menu for "Transparency". Set it to Straight Alpha and use Save As to make a new file leaving your original untouched for further editing.

  • How can I dispaly alpha Channels to proxy and show transparency correctly?

    Hi all! I have a problem. Please help me. Thank you very much.
    I want to display alpha Channels to proxy and show transparency correctly. I have get the datas of alpha Channels and RGB color. Following are the codes:

    (gFilterRecord->displayPixels)(&pixels, &pixels.bounds, 0, 0, (void *)hdc);
    delete[] overlay;
    But there is a problem.The image of alpha Channels in proxy is not clear, because overlay[i].opacity = 50 * 2.55.
    It looks like  diffrent from displaying in photoshop.I do not know how to use pixels.mat and pixels.masks.
    Thanks!

    I run the plugin. But It can not show alpha channels. Can you show the code in your example clearly.Thanks! Following are the frames.

  • BitmapData masking: how to merge 2 alpha channels?

    How can I apply an alpha mask from one bitmapdata to another? In other words, I want to merge the alphas, not simply copy one alpha channel to another bitmap.
    Here's an illustration:
    Notice that both the triangle and the ellipse have alpha channels, and the result is an intersection of these alpha channels. The RGB channels from the second image are used, and discarded from the first.
    I've looked into using BitmapData/merge(), draw(), copyChannel(), but they don't seem to do what I want. Anyone?
    Cheers.
    -Aaron

    Aha, looks like the answer was right under my nose: copyPixels() can do exactly this:
    If you include the alphaBitmap and alphaPoint parameters, you can use a secondary image as an alpha source for the source image. If the source image has alpha data, both sets of alpha data are used to composite pixels from the source image to the destination image. ThealphaPoint parameter is the point in the alpha image that corresponds to the upper-left corner of the source rectangle. Any pixels outside the intersection of the source image and alpha image are not copied to the destination image.
    Cheers.

  • How to use multiple alpha channels

    Hi there. I'm using Cinema4D for some 3D animation. I'm using an object buffer compositing tag to isolate certain elements in my scene. (C4D can create an alpha channel for each object). This is then rendered out as a multi-layered PSD sequence. However C4D puts the extra channel info (z-depth, object ID, etc) into alpha channels. But AFAIK, AE only reads the first alpha channel.
    Is there a way to read extra alpha channels?

    This topic came up about two years ago, you might try searching the forum.
    IIRC, the conversation was enlightening for several of us old timers who had never even heard of multiple alphas.
    Closest I've ever gotten was using the four separate color channels to hold unrelated grayscale movies. Each was used to drive a different 3d parameter of Card Dance.

  • Missing (or un-recognized) files - how do I fix this? PLEASE

    I  imported a number of old jpgs into my catalog (into seperate folders labled by year) but lightroom is not showing them in the library.
    IE: The folder for 2006 siys it has 583 files in it in the library.
         But when I navigate to the same folder using the finder (MAC OS10.6) there are 3047 files in it.
    I have 'optimized' the catalog.
    I have tried to 're-import' the files (add - 'do not import duplicates', in the import dialog) and lightroom shows no new fils to import!
    If I search for a specific file by name it does not show up in the Library. But if I try to re-import the same file it 'says' that it is a duplicate.
    Does anyone know what I should do to get correct access to the 'missing' files?
    LR4
    MAC OS10.6.8

    I'm not wanting to get in the way here, but before you go to the point of starting over with a new empty catalog, there is one thing you could try first. The problem may be similar to one that has been seem a few times before, and as I said earlier it usually centres around a problem with case sensitivity. For example a user may have his photos all stored in the path "HD/USERS/jonas/Pictures/ALL PHOTOS", but then either rebuilds existing system or moves to a new system...but in doing so sets up his user account name as Jonas, not jonas. Thus the path for new images in Lightroom becomes "HD/USERS/Jonas/Pictures/ALL PHOTOS", but it still has existing images linked to "HD/USERS/jonas/Pictures/ALL PHOTOS". This "dual path" happens because Lightroom is case sensitive, wheras the OS isn't. Lightroom records new images outside of the "ALL PHOTOS" structure, i.e. if you import into "Photos 2006", Lightroom creates a new sub-folder....but when it tells the OS to put the images into HD/USERS/Jonas/Pictures/ALL PHOTOS/Photos 2006 they get stored in the one and only physical sub-folder. Only Lightroom thinks there are now two paths, the OS still sees only one.
    Typically this can be discovered by doing the "Add Parent Folder" thing, that then shows which of the "two" paths that Lightroom sees needs to be corrected, but in your case you're getting that error message. So my suggestion would be to try the "fix" on all of the top-level folders currently showing to see if that can resolve the problem. That would be done like this:
    1. Take a catalog backup.....if this fix goes wrong you'd just trash the catalog and restore this backup.
    2. Outside of Lightroom, create 3 temporary folders at the root level of your HD (i.e. NOT inside your User path), call them "Dummy Import", "Dummy All", and "Dummy 2006".
    3. Back in Lightroom, using the Folders Panel, ctrl-click on "-IMPORT" and select "Update Folder Location". In the resulting file browser, browse to and select the "Dummy Import" folder. This will change the reference in the Folder Panel.
    4. Do the same on "ALL PHOTOS", relink to "Dummy All". In the Folders Panel "ALL PHOTOS" will change to "Dummy All" and all the sub-folders below will have the '?' mark to indicate they are now missing. Do not concern yourself with that at this stage.
    5. Finally, do the same with the "Photos 2006" folder which currently lies outside the "ALL PHOTOS/Dummy All" folder, relinking it to "Dummy 2006".
    6 The "Photos Pre 2006" folder outside of "ALL PHOTOS/Dummy All" has a zero photo count, so just ctrl-click on it and select "Remove".
    7 Now starts the phase of putting everything back together. First I would (using Finder), rename that "-IMPORT" folder to get rid of the hyphen, i.e. rename it to "IMPORT".
    8. Back in Lightroom's Folder Panel, ctrl-click first on "Dummy All", select "Update Folder Location", browse to and select the real "ALL PHOTOS" folder in your user/pictures folder....that should update the name in the Folder Panel and restore all the sub-folders.
    9. Now ctrl-click on the "Dummy Import" folder, select "Update Folder Location", browse to and select the "IMPORT" folder which is inside the "ALL PHOTOS" folder on the hard drive. "Dummy Import" should disappear from the Folders Panel, and "IMPORT" should appear under the "ALL PHOTOS" parent folder.
    10. Finally, ctrl-click on "Dummy 2006", select "Update Folder Location" then browse to and select the "Photos 2006" sub-folder which is inside the "ALL PHOTOS" folder on the hard drive. At this stage, you should receive a warning that the folder you have selected already exists, and gives you the option to merge them, Select "Merge" and "Dummy 2006" should disappear and the photo count for the "Photos 2006" sub-folder under "ALL PHOTOS" should increment by 755.
    What this procedure does is it allows you to correct any path irregularities caused by this case sensitivity issue, by moving the objects to a different temporary path, then putting them back to the one correct path (i.e. it gets rid of the dual paths that Lightroom sees). Bit of a kludge, but it might work out OK.
    And that should do it (takes less to do it than it's taken me to type the instructions)....but if anything fails along the way it may suggest that the problem is worse than I thought....let me know what happens if you decide to try it (no harm in trying it, provided you've got that backup done first).

  • How to use an alpha channel or transparency?

    I'm trying to make a game and I want to have a background and on top of that sprites. But the sprites need to be transparant in some parts. I have tried with gif's and png's but nothing works. Can anybody help me?
    this is my code, I don't use paint because I render actively in fullscreen exclusive mode
    private void initResources() {
    Image img;
    gc = getGraphicsConfiguration();
    try {
    img = ImageIO.read( new File("c:\\test.png") );
    sprite = gc.createCompatibleImage(100, 100, Transparency.TRANSLUCENT);
    if ( img != null && sprite != null )
    ((Graphics2D)sprite.getGraphics()).drawImage( img, null, null );
    catch ( IOException ioe ) {
    System.err.println(ioe.toString());
    private void renderFrame(Graphics2D g2) {

    g2.drawImage( sprite, 0, 0, null );
    g2.dispose();
    }

    Hm, seems like I found a partial solution myself using an AlphaComposite. Problem now is that it only works with gif's and not with a png.
    private void renderFrame(Graphics2D g2) {
    g2.setPaint( Color.BLACK );
    g2.fillRect(0,0,800,600);
    g2.setComposite( AlphaComposite.getInstance( AlphaComposite.SRC_OVER ) );
    g2.drawImage( sprite, 0, 0, null );
    g2.dispose();

  • Inconsistant alpha channel import on .mov files

    I am creating a movie using animation I create in Maya which is then composed in Shake with some alpha masks and exported using the animation codec to a .mov file into Motion. In reviewing my workflow (I'm about midway through things) I recognized I had an error in my screen sizes from one tool to the next and while it was not too noticeable, I thought it best to correct. This is where I should have left dead dogs lie.....
    Anyway, this is best described with the flow I show below:
    Motion Project Setup on ALL file types
    720x480, 8bit, NTSC D1/DV
    Lower First (Even)
    29.97 Fps
    Background Color - Black
    Background - Transparent
    Case 1:
    Maya__->_Shake___->Anim Codec_________>Motion 720x480
    720x486->720x486-->_Mil+_Col-->foo.mov-->File squished 6 pixels in Y
    but alpha is present
    Case 2:
    720x480->720x480-->_Mil+_Col-->foo2.mov->File is 8 pixels narrow in X
    alpha channel is not preset
    I open foo.mov and foo2.mov in shake and look at the files and the
    size is as follows:
    foo.mov - 720x486
    foo2.mov - 720x480
    BOTH .mov files have the alpha channel present and the data is correct.
    Just for grins, I output a file sequence of .tif files from shake of the
    foo2.mov files and verified that the alpha channel was present in
    photoshop and then did an import into motion with the same results of
    foo2.mov. Size is shrunk by 8 pixels in X and no alpha channel.
    It appears at least that Motion is making decisions based upon the screen
    size and importing or not importing the alpha channel.
    Any thoughts would be very much appreciated.

    Well, it is strange. Shake says it is 720 and for that matter so does Motion in the Media tab. Motion says it is 720x480 as does shake but when the clip is overlayed against the black background you can see 4 pixels on each side of the clip. The motion project file says it is 720x480 too.
    UPDATE....
    I just checked the motion file and deleted all of the media clips, but when I went to the media tab there was still one copy of the old 720x486 clip there. Every time and method I tried to delete it, it would crash motion. So, I copied all of the other text data I was using motion to generate, created a new motion project and pasted the text in. When I import the 720x480 file into the new project it lines up perfect. This must be a "feature mode" I must have gotten motion into.
    Anyway, problem solved. Thanks much for your help Andy. I kept looking at this and not seeing the forest for the trees.
    Much appreciated.
