Video Converter with Alpha Channel support

Looking for a video converter (.mov to .flv) that supports alpha channels

The APNG app is available for free in the app store, you can use it to download a video in APNG format on the iPad. You would need to make the video with an alpha channel on the desktop, but then just type of URL into the URL at the top of the app and it should download and play. There is already support in the app for changing the background color that appears behind the video.

If you are making a custom iOS app, then have a look at the AVAnimator library, it is what the APNG app was made with:

  • SWF doesn't play with alpha channel

    I have a 500Kb FLV file that plays as a progressive download through a 12Kb SWF. This FLV was encoded using On2 VP6 codec to maintain alpha data. This is a logo animation for a website so it is essential that the video plays with alpha channel intact. Just to make sure my animation had an alpha channel, I brought it into After Effects to test with a colored background behind it and sure enough, the alpha channel was there, perfect!
    Now in Dreamweaver, when I tested, the FLV plays through the SWF, as it should. However, there is a white square around my video now and the alpha channel is lost.
    I even made sure to select Wmode "transparent" and double-checked my code and saw that I had the correct tag <param name="wmode" value="transparent"/>
    View my site at http://www.customchromefx.com
    I have played many embedded SWF's with alpha's before. I think the FLV still has the alpha, and the problem is in the SWF that plays the FLV that is giving me the white box? Is there a way around this, perhaps a transparent SWF player or something? Thank you for viewing...

    Okay, so I figured out a way to make my compressed FLV video play with alpha.
    I imported into Flash. Checked the box to "Embed FLV in SWF" and clicked next, and Finish. I made sure the stage area and FPS was set to the same settings as the FLV video.
    In publish settings I used Flash 9,then un-checked compress movie and Published. This new SWF maintained the same file size as the FLV, while also playing with the alpha channel.
    I then imported the SWF into Dreamweaver, and set Wmode to "transparent." 
    I now have a 45 second video (originally a 115Mb quicktime) squeezed down to a measly 500Kb SWF that also has an alpha channel. Sweet!

  • 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.

  • 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?

  • Saving out with Alpha channel intact to windows machine? (Motion v3)

    I am working with someone who does video on his windows machine using Premier, but I use Motion to add effects to thier video.
    They are sending me a wmv version of the video, which I convert into prorez to work on (keeping frame rate and video size intact) and send the video to Motion to add the effects. Once I'm done I turn off the layer with the original video and send back to FCP.
    I want to save out a quicktime video from FCP with alpha channel intact so I can send the FX-only layer back to my workmate so he can drop it into his timeline on his machine and have everything align properly.
    Any advice on how to do this?

    If you have Compressor 4, check and see if you have the Animation codec. If you do, send the Motion project to Compressor and select the Animation codec with the setting 'Million Colors+'. The + (plus) is the transparent setting for the codec.
    Open the Motion app and drop the Animation video on top of something to make sure you have the transparency.
    Motion has ProRes 4444 that can contain a transparent background. Unfortunately, Windows computers do not support the ProRes codec.
    BTW, a transparent background will look black (sometimes white).

  • Smooth conversion of SWF to AVI with Alpha Channel

    today i tried a program which claims the unique program in
    the world can convert
    SWF to AVI with alpha
    channel, i find that this is the best program which can
    synchronization audio and video, and there won't be watermark in
    the middle of your video, i can also use it to capture pictures
    when i play the swf file, it is a good function that i can put the
    picture in my phone

    Hi there Schumi-z!
    Well, it seems many poeple have the very same problem. Let me explain what I have got and what I look for.
    I am working on a simple video editor. This program is to take a video as input, read the video and "chop" it automatically. Taken certain frames to different new videos, from one to 10 or more, according to certain parameters of the frame analized.
    What I have got until today is a way of opening the video, reading it frame by frame, extracting a frame, analize it. But I'm yet to develop a way to write new videos taking a group of this previously separated frames.
    I would like to know, if you are trying to solve the same or similar problem which in any time it envolves writing a new video file, so we can work together and solve this problem as soon as possible.
    This work is also a part of my research to complete my thesis work. It would be an honor to have a quote mentioning someone from around the world.
    Well, I hope to hear from you soon.
    Have a nice day

  • Can no longer import QT files with alpha channel

    I have been using these client supplied QT with alpha channel files just fine for weeks, then all of a sudden, after a crash the other day, I was unable to open sequences with these files and exoprt them, the exporter would just freeze.  the clips played in the timeline, but VERY sluggish.
    On the reccomendation of a few posts around here, I removed the clips from the project, and now I cannot import them back in, I get a "the importer reported a generic error" message.  I am able to open in QT pro and export to a new file that will import to PPro, but I lose the alpha channel.
    As always, I'm up against a deadline and any help would be greatly appreciated.
    I have installed QT 7.07, no help.
    I'm on a windows 7 machine running CS master collection 5.0, Quad core AMD with 8 gig RAM.
    These files worked fine just days ago!!!!
    BTW, I just switched over to Premiere a few months ago and to honest I can't understand how anyone would stick with this buggy software, as a professional I've never used anything this bad before.

    Welcome to the forum.
    Try these.  Attempt to re-import after each one:
    Clean the media cache database via Edit | Preferences | Media
    If step 2 doesn't work, then find all the .qtindex, .mpgindex, .cfa and .pek files associated with the media that's supposed to be in your project and delete them.  Then clean the media cache database again.
    Launch Pr and while it's launching, hold down the Alt + Shift keys until the Welcome screen appears.  Alt resets your preferences and Shift resets the plug-in cache.
    To address the other issues you say you've been having with Pr, you should start a different thread (or threads).  Coming from other editors, there may be a difference in the way Pr does things that produce unexpected results that may be seen as bugs.  More serious issues, such as crashes, can often be caused by 3rd-party hardware like AJA, Matrox or BlackMagic and the associated drivers.  Outdated or incorrect drivers for audio and video cards can also cause problems.  I recommend that you start troubleshooting those areas first.
    Other issues may have workarounds.  If you have serious, reproducible problems that have no workaround, then please file bug reports here:

  • No Method of Batch Export for Clips with Alpha Channels?

    Good morning,
    As many a flustered editor has eventually discovered, in order for FCP to export sequences with alpha channels to a 32-bit format, the timeline has to be un-rendered at the time of export, or else the transparent parts will appear black in the outputted file. This sort-of makes sense if you know how FCP and render files work, but in a perfect world I think I'd have designed the export interface a bit differently. Now that I think about it, I'm actually working in an Animation (Millions of Colors +) sequence, so converting transparent areas to black makes no logical sense at all.
    Anyway, I have several sequences that I would like to export as 32-bit TGA QuickTime files, preserving their transparency. If I Export Using Compressor, the process results in pre-rendering of the sequence, turning the transparent areas black. The same problem occurs if I export QuickTime reference movies from FCP and open them directly with Compressor.
    Does anyone know of a way to avoid this silly phenomenon or am I stuck individually exporting each sequence from FCP, one...at.......a................time?
    Thanks,
    Zap

    Thanks, Andy, "Batch Export" eventually did the trick!
    I forgot about that tool because I've never actually had to use it before! After playing around with it for a while, I found that as long as the sequence settings for each sequence in the batch are set to a codec with an activated alpha channel, it works just fine.
    Thanks again,

  • ImageIO PNG Writing Slow With Alpha Channel

    I'm writing a project that generates images with alpha channels, which I want to save in PNG format. Currently I'm using javax.ImageIO to do this, using statements such as:
    ImageIO.write(image, "png", file);
    I'm using JDK 1.5.0_06, on Windows XP.
    The problem is that writing PNG files is very slow. It can take 9 or 10 seconds to write a 640x512 pixel image, ending up at around 300kb! I have read endless documentation and forum threads today, some of which detail similar problems. This would be an example:
    [http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6215304|http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6215304]
    This surely must be resolvable, but after much searching I've yet to find a solution. If it makes any difference, I ONLY want to write png image, and ONLY with an alpha channel (not ever without), in case there are optimisations that that makes possible.
    If anyone can tell me how to address this problem, I'd be very grateful.
    Many thanks, Robert Redwood.

    This isn't a solution, but rather a refinement of the issue.
    Some of the sources I was reading were implying that the long save time might be due to a CPU heavy conversion process that had to take place before the BufferedImage could be saved. I decided to investigate:
    I loaded back in one of the (slowly) saved PNG images using ImageIO.read(file). Sure enough, the BufferedImage returned differed from the BufferedImage I had created. The biggest difference was the color model, which was DirectColorModel on the image I was generating, and was ComponentColorModel on the image I was loading back in.
    So I decided to manually convert the image to be the same as how it seemed to end up anyway. I wrote the following code:
          * Takes a BufferedImage object, and if the color model is DirectColorModel,
          * converts it to be a ComponentColorModel suitable for fast PNG writing. If
          * the color model is any other color model than DirectColorModel, a
          * reference to the original image is simply returned.
          * @param source The source image.
          * @return The converted image.
         public static BufferedImage convertColorModelPNG(BufferedImage source)
              if (!(source.getColorModel() instanceof DirectColorModel))
                   return source;
              ICC_Profile newProfile = ICC_Profile.getInstance(ColorSpace.CS_sRGB);
              ICC_ColorSpace newSpace = new ICC_ColorSpace(newProfile);
              ComponentColorModel newModel = new ComponentColorModel(newSpace, true, false, ComponentColorModel.TRANSLUCENT, DataBuffer.TYPE_BYTE);
              PixelInterleavedSampleModel newSampleModel = new PixelInterleavedSampleModel(DataBuffer.TYPE_BYTE, source.getWidth(), source.getHeight(), 4, source.getWidth() * 4, new int[] { 0, 1, 2, 3 });
              DataBufferByte newDataBuffer = new DataBufferByte(source.getWidth() * source.getHeight() * 4);
              ByteInterleavedRaster newRaster = new ByteInterleavedRaster(newSampleModel, newDataBuffer, new Point(0, 0));
              BufferedImage dest = new BufferedImage(newModel, newRaster, false, new Hashtable());
              int[] srcData = ((DataBufferInt)source.getRaster().getDataBuffer()).getData();
              byte[] destData = newDataBuffer.getData();
              int j = 0;
              byte argb = 0;
              for (int i = 0; i < srcData.length; i++)
                   j = i * 4;
                   argb = (byte)(srcData[i] >> 24);
                   destData[j] = argb;
                   destData[j + 1] = 0;
                   destData[j + 2] = 0;
                   destData[j + 3] = 0;
              //Graphics2D g2 = dest.createGraphics();
              //g2.drawImage(source, 0, 0, null);
              //g2.dispose();
              return dest;
         }My apologies if that doesn't display correctly in the post.
    Basically, I create a BufferedImage the hard way, matching all the parameters of the image I get when I load in a PNG with alpha channel.
    The last bit, (for simplicity), just makes sure I copy over the alpha channel of old image to the new image, and assumes the color was black. This doesn't make any real speed difference.
    Now that runs lightning quick, but interestingly, see the bit I've commented out? The alternative to setting the ARGB values was to just draw the old image onto the new image. For a 640x512 image, this command (drawImage) took a whopping 36 SECONDS to complete! This may hint that the problem is to do with conversion.
    Anyhow, I got rather excited. The conversion went quickly. Here's the rub though, the image took 9 seconds to save using ImageIO.write, just the same as if I had never converted it. :(
    SOOOOOOOOOOOO... Why have I told you all this?
    Well, I guess I think it narrows dow the problem, but eliminates some solutions (to save people suggesting them).
    Bottom line, I still need to know why saving PNGs using ImageIO is so slow. Is there any other way to fix this, short of writing my own PNG writer, and indeed would THAT fix the issue?
    For the record, I have a piece of C code that does this in well under a second, so it can't JUST be a case of 'too much number-crunching'.
    I really would appreciate any help you can give on this. It's very frustrating.
    Thanks again. Robert Redwood.

  • Flash Player for FLV files with alpha channel encoded

    My goal is to play the the transparent background flash video on the bottom right hand corner similar to the video on this website : http://www.dropshipblueprint.com/
    I already have the FLV file with alpha channel encoded.  I was made to understand I will need a special flash player that can read alpha channel in the flv file to make the background transparent? Is this correct? If yes, then how to accomplish this or where do I get that player, maybe opensourece player?  If the player is not a solution then how do I accomplish my end objective taking into consideration I have the FLV file with the alpha channel encoded.  Thanks for your help. Sam

    Sam,
    Welcome to the forum.
    Where do you need to play this "sprite" (the name for such a Flash video)?
    If you need to add that to a Video, then there could be a few challenges in PrE.
    If you need to add it to a Web site, then Flash Player (free from Adobe) should be able to display that.
    Can you please give us just a bit more info, on how you wish to use the sprite?
    Good luck,

  • Automator or Applescript using png files with alpha channel

    I have hundred of png files with alpha channel.
    I want to suppress alpha channel.
    How can i do it using Automator or Applescript ?
    Thank you very much.

    You can use the free command line image processing tool ImageMagick in your Applescripts or Automator workflows, as well as from a Terminal shell.
    You can download ImageMagick from http://www.imagemagick.org, but Cactuslab has simplified installation by putting together an installer package. It’s available at  http://cactuslab.com/imagemagick/. Download the package and double-click on it. Follow the instructions to install. It will install ImageMagick into /opt/ImageMagick and add it to your $PATH by creating a file in /etc/paths.d/. Restart your computer for the changes to take effect.
    The two ImageMagick commands we’re concerned with are “convert” and “mogrify”. Convert is more efficient for multiple and piped operations on the same image file, and mogrify is more efficient for batch processing. Generally speaking, convert will output a file separate from the input file. Unless a path is specified, mogrify will overwrite the input file with the output file. An important distinction.
    You can perform various operations on the alpha channel using arguments after either the convert or mogrify command. Two of the available arguments are:
    -alpha off - Disables the image's transparency channel. Does not delete or change the existing data, just turns off the use of that data.
    -alpha remove - Composite the image over the background color.
    Also of use are the -flatten and -background options:
    -flatten - overlay all the image layers into a final image and may be used to underlay an opaque color to remove transparency from an image.
    -background - sets the background color.
    Start off using the convert command with a single image to see the effect and adjust to your liking. Once you’ve achieved the desired outcome, then use the mogrify command to batch process the chosen images.
    Before getting into how to use Automator or Applescript in your workflow, use Terminal and the command line to see the effect on a single image. Copy one image to your ~/Desktop. In Terminal change the directory to ~/Desktop by typing the following command and pressing the Enter key:
    cd ~/Desktop
    Then choose the option you are looking for, -alpha remove for instance, type the following command and press the Enter key:
    convert input-photo.png -alpha remove output-photo.png
    You can check the alpha channel (transparency) and background in the Preview app, go View > Show Image Background from the menu bar.
    Once you’re ready to batch proces, place all the photos you want to convert with the same command into one folder. Copy the folder to your ~/Desktop. Let’s assume you’ve labeled the folder “InPhotos”. It’s prudent to manipulate copies in case something goes amiss. In that event you can copy the folder with the originals again and start over. Create a new empty folder on your ~/Desktop and call it “OutPhotos”. Let’s also assume your home directory is called “Me”. The following command will process the photos from the InPhotos folder and put them in the OutPhotos folder:
    mogrify -alpha remove -path /Users/me/Desktop/OutPhotos/ /Users/me/Desktop/InPhotos/*png
    According to Apple Technical Note TN2065:
    "when you use just a command name instead of a complete path, the shell uses a list of directories (known as your PATH) to try and find the complete path to the command. For security and portability reasons, do shell script ignores the configuration files that an interactive shell would read"
    So, you need to use the full path to to ImageMagick commands, unlike in the shell where you can just use the command name.
    To batch process using Automator, use the “Run Shell Script” action (note: retain the single space at the beginning of the last line):
    /opt/ImageMagick/bin/mogrify \
    -alpha remove \
    -path /Users/Me/Desktop/OutPhotos/ \
    /Users/Me/Desktop/InPhotos/*png
    To batch process using Script Editor (Applescript), use the “do shell script” command:
    do shell script "/opt/ImageMagick/bin/mogrify -alpha remove -path /Users/pd/Desktop/OutPhotos/ /Users/pd/Desktop/InPhotos/*png"
    Further info on ImageMagick:

  • 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.

  • Import QuickTime with Alpha channel into Flash CS3

    Is it possible to import a QuickTime movie with alpha channel into an FLA and have the FLA recognize the Alpha channel? When I've done this, it just shows opaque black instead of an alpha channel. I need that black to be transparent so I can see the layers below the video layer.
    Thanks in advance for any help.

    I don't know the answer to your question.
    Do you have a video player where you can verify that the alpha channel in the video is displaying as you expect?.... that is, the background is transparent?
    I have used flv files with alpha and a NetStream vid player to overlay Flash video on a Web page.... but not directly in the timeline.:
    http://www.mrfilmbiz.com/
    the walkon... could have had other action (like Flash artwork) going on in the background... but that may not really be what you are looking for.
    But lacking any other solutions, you could have your alpha channel vid file playing in one Flash file over the top of a second Flash file doing the artwork stuff.
