Exporting an Alpha Channel in speedgrade cc

Can I export an alpha channel from speedgrade back to premiere pro cc, for compositing after color correcting my actor?
Thanks

QuickTime Pro does support alpha channel masks.
Open the file in QuickTime Player Pro and select 'Window>Movie Properties'.
Go to 'Video Track' and click the 'Visual Settings' tab.
If the file contains an alpha channel, a black and white image should appear in the bottom left of the Properties box. This is the mask, or alpha channel mask.
Click on the image. A blue line appears around the image.
Select 'Edit>Copy'.
Open Preview and select 'New from Clipboard'.
The mask can then be saved as a PNG, TIFF, PICT, etc.
The saved mask can be attached to other images. In Properties, click the 'Choose' button and select the mask.

  • Can't export with alpha channel - Again!!!,

    So, I have an intro that is designed as an overlay of the incoming video. The objects move out the way to reveal the video underneath. BUT, when I export the sequence the resulting movie has black in the background.
    Now, I had this issue several months ago, and after tons of research and trial and error, all of a sudden it worked when I came back to Motion on another project. No explanation. It just worked.
    Usually, I have the background set to Transparent and then export using Lossless and Alpha. Works fine. Well, not today. I've changed every export setting under the sun trying variations of Lossless with Alpha and also tried the Animation codec. No luck.
    So, what is going on? Any thoughts?

    Thanks for your help Patrick. I tell ya, I can't believe what's going on. As I said, this project until today has not caused me any issues what-so-ever. The other six sessions are totally fine. I also created a quick project with the same settings added text - then exported using the same settings I've used before, and it exports with the proper alpha channel.
    Yet, I rebooted the Mac, made sure to delete old versions in the trash can and everything. Still, no alpha.
    To keep moving forward, I literally had to use a color key in FCP to cut out the background color.
    Crazy!

  • Exporting with alpha channel and edges are ragged

    I've got a short animation that is mainly a PSD of a map of NC with some animated push pins on it. I've got a local cable provider wanting an export of the animation with an alpha channel. He's using Premiere on a Mac, I'm on PC. No matter what codec I use that supports an alpha channel, the outer edge of the graphic of the State comes out ragged. Zooming in to the PSD in PhotoShop shows that the edge is antialiased, so I would imagine that this is what is causing the ragged edge on export.
    Here's grab of the export. This is with QT Animation codec-quality 100, but the same results occur with DNxHD, Cineform, PNG, etc.

    I think you are just seeing the extra areas of the fill.
    If the output files works correctly in the editor, you should be good to go.

  • I want to export with alpha channel using a codec that carries less data than gopro cineform

    Hi--I want to export some intermediate files with an alpha channel. i'm using gopro cineform, and these files end up being so large, meaning that i have to sit through hour long renders.  is there a a codec i can use that has an alpha chanel but creates a smaller file size?
    thanks

  • Can't export with alpha channel

    PROBLEM: No matter what export settings I use or manipulate I can't get the exported movie to have an alpha channel.
    I've read several threads on this, and none of them solved my issue. Temporarily I just imported the Motion 3 project and used it as my overlay video - it's a title intro that slides out to reveal the video underneath it.
    However, I'd prefer to create self-contained QT's as there are 7 sessions.
    In After Effects I'd typically choose Animation and select 'using Straight Alpha'. Motion has a preset of Lossless + Alpha Movie, or you can go to advanced and select Output tab and deselect Pre-multiply Alpha. Neither works. The exported video still has black. What's totally insane is that I was using these settings up until today and everything was fine!
    And yes, I've chosen 'Transparent' under the view options and still black is always included.

    We do have an answer, it's usually a simple user error: not being able to tell the alpha is really there. If you're watching in QTPlayer, you will see black. If you open the movie in FCP, you should be able to change the alpha interp to suit.
    Even if OPs claim to have tried this, it's still the first thing that comes to mind and, since the OPs rarely return to tell us what REALLY happened, we are left with the assumption that this was the problem all along.
    If you set your render controls to Animation with millions of color + (many of us simply forget the PLUS) and we presume there is no solid shape or opaque layer (easily missed in Motion's weird timeline display) it is fundamentally impossible not to get an alpha.
    Not to say it can't happen but I've been on support forums for AE, Media 100, FCP and others for more than a decade and I have never heard of the Animation codec actually failing. It is always user error or a broken application.
    I hope you folks find a new and unique solution that we can add to the list. But this is the best we know to give you: Check and recheck the easy stuff.

  • EXPORT WITH ALPHA CHANNEL

    I need to know how to export a clip with the alpha channel intact. I keyed a green screen shot and exported it, but everytime i open it in final cut it has a black background. Need help asap it is the last shot I have to do for a music video that has to be done by monday, thanks.

    Are you sure your alpha is there? (check by pressing "a" with the mouse over the view window).
    Did you try telling FCP that there is an alpha channel? If you did "Send to Shake", Final Cut Pro doesn't expect that the QuickTime it's getting back will contain an alpha channel (It's meant to match your sequence settings). You might try dragging the output directly into the browser to re-import it and see if it recognizes the alpha...
    As a matter of fact, maybe you can check in QT Player, load it into QuickTime Player, cmd-j, click on the video track and play with the transparency setting. Try Straight Alpha - that should lead to the background going white - then you'll know its coming out of Shake properly and concentrate on getting FCP to recognize it...
    If all else fails (I did just try it here and it worked), maybe try a TIFF or TGA sequence?

  • DNxHD (.mxf) export with alpha channel

    Hello!
    I'm working with one Finnish children's feature film which will star end of this year as an DIT. Movie will include lot's of green screen and the production want's me to do chroma keyed DNxHD 36 renders with alpha channel for AVID editorial. So far I have found out that neither davinci desolve nor assimilate scratch can't do it.  Is it possible to render DNxHD with alpha channel from AE? And can Avid import these files with alpha channel? All help is needed and appreciated.
    Cheers

  • Alpha channel loss at export

    Hey guys,
    HELP!! I can't figure out why I get a blinking effect (when I say blinking, it might blink 2-3 frames of black throughout a 60 second sequence)when I try to export my alpha channel animation sequence. It plays back just fine in FCP until I export it and open it up into motion. Everything looks great in motion except for the 2-3 frames the background blinks to black. I'm trying to get this project done ASAP, but this tiny problem is holding me up!! Any ideas??
    Also, just FYI: as far as filters that I'm using on the clip: Chromo keyer, 3-way color correction, 8-point garbage matte, and I'm using a slight drop shadow with the motion tab. THANKS

    Zoom in on the timeline in whatever program you created the sequence in. Zoom in to the trouble area and make sure you don't have a very small gap between the clips. Unless you are all the way or at least almost all the way zoomed in, you would not be able to see a small 2-3 frame gap.

  • Alpha channel related export/import

    hello
    i have a shot in animation that has a flower bouquet wiping across he screen diagonally left to right
    problem is there is no alpha channel attached so i cant see whats underneath when it wipes
    do i have to:
    import this into after effects - mask out everything but the bouquet
    then export with alpha channel
    then import into final cut
    thanks
    craig

    it was created in Maya as a shot
    i guess we either have to have the animator resend the Maya file with an alpha channel
    All you need is the alpha version of the shot and run it in sync as a track matte. You don't the whole shot rendered again, you just need the grayscale/alpha/shadow pass, whatever it's called in Maya. However, are you sure you can't pull amatte from the shot as it is? Isn't it matted over superblack or does it have a premultipled matte/alpha?

  • Alpha Channel Export

    Having trouble exporting an alpha channel from FCP 5.0 for use in AE 6.5 Pro. My steps: From FCP, export QT conversion using Animation codec, Millions of colors+. Import into AE, use set matte effect with correct layer and use for matte: Alpha Channel. No transparency though. Help.

    If your sequence settings are not set to animation/millions of colors +
    Actually learned that part here from "worldwidestudios".

  • No alpha channel when BCC lens flare applied

    Hello
    With the help of Andy Neil, I created a light sweep for a lighthouse logo. I added a BCC RT Lens Flare Adv filter to enhance the effect of the light sweeping past the viewer. I looked great.
    Then I got to thinking that the lighthouse logo with light sweep would make a great lower third, so I scaled it down to logo bug size and superimposed it over a lower third background.
    The problem is that the inclusion of the BCC Lens Flare filter seems to add a black layer over the entire movie so that the lower third cannot superimpose over my talking head. I know it's the BCC Lens Flare because when I deactivate the filter and export, the alpha channel is present and the lower third is superimposed over the footage.
    I've tried exporting with Lossless+Movie Alpha and Animation,
    My question: Can anyone tell me why this is happening and how I might be able to remedy?
    Thank you,
    Blake

    Yes, the lens flare is the problem. The generator is rendered as a blend mode which blends only with the elements in the project. The blend doesn't export as transparency because a blend mode is only transparent when combined with another layer.
    Here are your solutions:
    1) Composite the lower thirds with the video in Motion. If the bkg layer is in Motion, then the ADD blend mode applied to the lens flare will work properly.
    2) Create an alpha matte layer. This requires you to create a black and white image of your project that defines transparency for your lower 3rd. Export that as well, and then do a Composite Mode-Luma in FCP.
    3) Apply a Luma Key to your lens flare before export. This works, but is imperfect because the filter will inevitably key out some of the not-so-bright aspects of the lens flare, leaving you with a diminished result.
    4) (My Suggestion): Apply the lens flare in FCP. FCP contains the SAME lens flare generator used by Motion. This will give you the best possible result with the least amount of extra work on your part.

  • Rendering the alpha channel

    Hi guys I have shot some video against greensreen,keyed out the green and want to save file with the alpha channel because I want to place the keyed video inside an animation applictaion(cinema4d).
    I would like to know how can I render my keyed video in shake so that when I place it in the animation program I only get the subject and not the subject with a black background??
    Thanks a million
    Danny

    you nedd to render out the images in a format which carries alpha - like a targa and be sure to highlight rgba - the a standing for alpha.
    otherwise you could do a reorder to aaaa and export the alpha channel as a black and white image in another format and use it as a matte in cinema 4D? (can you do that in cinema 4d?)

  • Export FLV Alpha getting a white puppet

    Hi thanks for looking in.
    I created a Puppet animation using the 'pin-tool' went to export it as an FLV for size and upon opening I am getting a white Alpha character where my detailed puppet should be.  What am I missing here?
    I want to export my Puppet with an Alpha BG not an Alpha character? I would like the webpage to show through the BG and not be on a Black BG....
    Settings are:
    Resolution: Half--Did not need a 1920 x 1080
    Format FLV
    Output Info On2 vp6
    Bitrate 1600.00kbps
    Include: Project Link
    Channels: Alpha
    Depth: Mill of Clr
    Color: Pre-Multiplied
    Final size 960x540
    Output to FLVAlpha

    Your settings say that you're just exporting the alpha channel, which will create an luma matte (white on black). So, what you're seeing is normal.
    You need to choose RGB+Alpha, not Alpha as the channels to export.

  • Exporting SpeedGrade Project with Embedded Alpha Channel

    Hello! I am currently writing with a problem I can't seem to find a solution for in SpeedGrade. My problem is that I imported footage with embedded alpha channel enabling me to chroma-key out a green screen. I would like to export this file now with the alpha channel still embeded to be delivered to Premiere. Is this possible?
    Your help is greatly appreciated!
    Philip

    Thanks Fran,
    I'm using uncopressed QT, animation.
    I did the color correction on a grading track and I think that's what killed the alpha, because when I selected the track with the footage the alpha was being read properly. So what I did instead is I saved a .look file and imported it in After Effects, I rendered from there.
    Can you have the grading track read the alpha from the original footage or if not can you copy the attributes from one track to another, as if I was moving all the grading from the grading track to the footage tiself instead of having to do it again from scratch?
    Thanks again,
    David.

  • 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
