Replacement for FLV with alpha channel

Hello,
is there some way how to encode video with alpha channel for usage in Flash, when Adobe removed flv encoder from all applications in CC?
Thank You,
T.

I wonder too if this issue has been addressed yet in CC 2014, or are user till forced to go back to older version of ME if this functionallity is essential to them?

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,
Zap

Merge 2 files for masking with alpha channels

Dear all,
I have like hundreds of files. Each file has it's own "sister black&white file" which is ment to be used as a mask.
I was wondering if it is possible to automaticly merge those 2 files so we would end up with a masked image..png or whatever....
It would be a monster job to do it all by hand...
Maybe a a script or badge???
kind regards,

I adapated the orignal script - and ended up with a png but....with a jpg extension..
that's a little stupid.
I am not able to find how to correct this...
My adaptions in red...please help

Sudden problem with importing tiff files with alpha channel (CS5)

OK this is driving me nuts. For years I have been importing image files that have an alpha channel into FCP as.tiff files. I use Photoshop files only when I want to use the layers as they are too cumbersome otherwise). I have recent upgraded Photoshop, etc. to CS5 and now FCP won't import them anymore. I get a message saying: "File error: 1 file(s) recognized, 0 access denied, 1 unknown"
I am not doing anything different and tiff files created in just the same way in an earlier version of Photoshop import and work just fine. Is this a CS5 bug? Does anyone know of a work around. I want to keep using tiff files as they seem to work best for me with alpha channel work (and I don't see why I need to reinvent the wheel).
Thanks
A

I've had a similar issue recently. Same TIFF files downloaded from the same server, different FCP project, new error. I either see"File error: 1 file(s) recognized, 0 access denied, 1 unknown" or I get the even stranger, "Unrecognized file type."
I can open them in PS and save them again as TIF, same results. I know these are not CMYK files but even if resave the TIF as RGB, I get the same results, they are not recognized by FCP.
But if I open them in PS and save them as PNG with alpha, they improt fine.
I have no idea what's going on.

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,
Hunt

Why can't I see the Finder thumbnails for .mov files with alpha channels?

Ever since I upgraded to Mavericks I haven't been able to see the thumbnail for or preview using spacebar any .MOV clips that contain alpha channels in Finder. PSDs and PNGs with alpha channels are fine, and I can still see their thumbnails and previews, it's just .MOV clips with alpha. Here are a couple screenshots:
Most of these clips are using a PNG codec, but I converted on to the Animation codec and tested it in After Effects to make sure it kept the alpha channel and it did, but the same thumbnail error persists.
Any idea why this might be or how to fix it?

Thanks.

ok, have copied the photos again from the memory card and hey presto, it all works fine. So in summary...for RW2 files from GF1 camera, I have no thumbnail images, couldn't view in Preview, and neither Quickview nor Coverview were working. Ran the bit of code provided at "https://discussions.apple.com/message/18369759#18369759" (thanks to Snoop Dogg) and then recopied the photos onto my Mac (only required for photos copied since upgrading to Lion, everything from before the upgrade is fine anyway).
Hope others find this helpful.

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!

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.

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:

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.

Problem with Alpha Channel

The top level track on my project contains an alpha channel. However, being the top level track the tracks below it are invisible.
I have read the "Compositing, alpha channels, and adjusting clip opacity" page. It tells me that I "can choose how to interpret the alpha channel in a file in the Interpret Footage dialog box. Choose Invert Alpha Channel to swap areas of opacity with areas of transparency, or choose Ignore Alpha Channel to not use the alpha channel information at all."
However, when I do this (ie. inverse the alpha channel in the asset) I get the following before and after results:
Summary of goal: I want to adjust the transparency of the top track so that the lower tracks appear.
Help.

If you want to adjust the transparency of a clip, you modify its Opacity property.
Changing the alpha channel properties in the Interpret Footage settings is for when the alpha channel of an asset is not being interpreted/used correctly by the application.

Question: Quick Look in Finder; problems with alpha channels

Hi
"Quick look" in Finder is great for quick presentations of a folders selected contents but it only works with images that contains no alpha channels or masks. Is there any way to work around this to display say PhotoShop documents with alpha channels? Or any plug-ins/applications that can help?
thanks.

This has been broken forever in OS X, and I don't know why, because it used to work just fine. I suspect the engineers did something to QuickTime that causes this problem, but it has been borked for so long I don't remember when the ability to correctly display files went wrong. I just remember that once upon a time all sorts of things from Apple worked correctly in displaying such files, but pretty much nothing does now. This includes the Finder, Preview, QuickLook, and various third-party image browsers that use Apple's own system level image handling abilities, such as VitaminSee or CocoaViewX. When I need to actually see what's there, I browse with Adobe's Bridge.

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?

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 render with alpha channel?

Hello,
I am trying to render a comp with alpha channel QT PNG. When i play the clip it's with black BG but if i imported in AE is with alpha channel. How to render in such way that i can play in Quicktime without the black BG? Am i missing something?
Thanks!

Thanks!
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.

Adding logo with Alpha channel to Quicktime and exporting as .mp4

I'm adding a PNG file with alpha channel to my existing movie file using "Add to Selection and Scale".
I then have my movie with the overlayed graphic.
When I then Export as an mp4, the alpha channel is ignored!
Any help, anyone?

Yes it looks perfect in Quicktime.
But for some reason I can't save it as anything else or even export a still frame without the alpha being ignored and the image going all fuzzy.
