• An Alpha channel in 5 motion editing

  I used chromatic key successfully in many video projects Motion 5, but now I am interested in editing and in some cases, remove a layer alpha to any clip. I have read the user manual and learned about the export of the video using Apple ProRes 4444 and ensuring the drop down choices include color or color and alpha, but I think my question just before exporting.

  I bought video clips for use in my projects with alpha channels deleted and I would like to explore using this kind of function change myself.

  I'm just exercise wishful thinking here or is to detach the data of possible alpha channels in the query editor 5 no matter where I export the video?

  Thanks for any help to a novice Editor to the-middle-level-qualified.

  Well,... no way alpha... ? something, some content, for example a solid color

  and it is set in the project properties, see:

  

  the two parameters of canvas even look: black.

  but when exporting with the setting on the right, instead of an alpha = transparency, the selected color fills the background.

• keep an a 1 bit image alpha channel

  Greetings!

  I do a lot of pre-press and the restoration work for printing, mostly working with equipment that requires released as a 1 bit image - very fine line work and mechanical tones that will break or cause the moire if printed with dithering.

  For this reason, when you work with commercial printers I've out usually images with superior typical resolutions - 1 bit 2400 ppi files, i.e. the same their imagesetter resolution works.

  I have a request current a client that involves, at their request, to place images with transparency in Indesign rather than manipulate raster images in Photoshop and just out of the final 1 bit image and placing in Indesign.

  So, I was playing with alpha channels to try to find a solution to this. Is there any image format that will support two channels - one for a piece of mono ppi (1 bit) 2400 line drawings and the other for an alpha channel that will be used to hit transparent sections in Indesign after the fact? Is this possible?

  I COULD simply threshold - adjust my image to make pseudo-1-bit and then place the file in Indesign. But it's a big waste of space (the file resulting in dozens of times larger) AND it makes it more likely that someone will accidentally mixed the image during the RIP to print, thus defeating the objective of providing a high resolution 1-bit image in the first place.

  Please, please, anyone out there have any advice for me?

  Best,

  Well, the next day-

  I read some more about how little coding works on different file formats. There is no place for the information/alpha channel for transparency on image 1 bit because, well, there is only a single bit, i.e. two States - on (ink) or disable (paper). If the shutdown state is managed like a white by Indesign, or the stop State is managed as paper and is presented in a transparent manner.

  So what I really need, is a 2-bit image format. A PNG. While there are four States - on (ink), (off-white) and another way for transparency.

  So I have 'threshold' converted by alpha channel and my channel of the image, then to export--> save for Web (inheritance) and selected 4 color PNG. Voila! Perfect bitmap 1-bit with transparency.

  Now, if he is a pretty good solution for my printer and their Raster image processor, we get to see!

• MOV file with too large Alpha channel

• Alternative to the QuickTime Animation - alpha channel & small size?

  • I am looking for a replacement for the Animation QT codec I used to use for video files with a channel alpha on a Windows System.
  • Apple QuickTime does not support Windows more and I'm scratching my head to find a good video intermediate container/codec that takes in charge graphic overlays alpha channels.  I'm looking for something that implements a clip of 10 minutes gradually around 1 or 2 gigs or less.  Compression is acceptable.   I reuse these overlays on each video that I exported and found there was a reduction of duration important export RGBA images rather than dynamic links to After Effects.
  • My best guess is to use JPEG 2000 level 1 in one. Enveloping MXF?   Any other suggestions or ideas?
  • JPEG 2000 lvl1 I get an error in the first when importing JPEG 2000 MXFs, but somehow from one day to the next the error disappeared.  The 10 minute file moved to 976 326 KB which is ~1.5 GB smaller than the Animation QT codec. He use that throughout.
  • I tried the PNG sequence, and it was the smallest (I think), but it cannot be contained in a single file, it is unusable in our workflow.
  • I tried the Targa sequence, which was a lot more big 34 k vs 8, 000 k.
  • I tried the GoPro Cineform, which although is listed as QT always worked without QT installed.  It worked fine, but the files turned out to be astronomical in size and much larger than QT Animation.
  • I tried DNxHD, but the files are too big, and I have found no RGBA option to export even if takes care of the format specification.
  • I tried AVI (uncompressed), wow.  File size would have taken a hard disk video sequence.

  Thanks for the help and suggestions, if someone reads this knows a better way, please share.

• How can I make a stronger alpha channel?

  I was using Gimp to make stronger with adjust the curves of colors of alpha channel and selecting Alpha.
  How it can be done with Photoshop CS6?

  What I want to do is to make more visible alpha channel. In my case, it's simple image of triangle.

  

  In the case of the triangle. If black pixels have a certain transparency and you want them to be fully opaque, the magic tool you want to select the triangle, then fill it black.

  

  

• Apply alpha channels

  Is it possible to apply (activate?) an alpha channel in one image, other than when importing?

  I use two images superimposed for a special effect, the bottom without alpha and the top channel and would like to be able to apply an alpha channel to the image without having to replace the image each time. Paths of shadow in Indesign will not work, I can't have hard edges.

  I use AE CS6 home and CC to work. I'm out to h264 with alpha channel to create a lower thirds for use in of Telestream Wirecast. I used to use only the queue rendering but now forced to use Media Encoder with no visible value to RGB + alpha. I'm on Windows 10 with a date limit.

• Problem with Alpha channel on AfterEffects composition

  Hello

  I'm editing a short film called 'Lost In Time' and one of the sequences is supposed to reflect a 1920s silent film, but Adobe AfterEffect records the images as color, even if on Premiere Pro, it was published in black and white.

  I tried to turn off the alpha channel, but it won't let me click on 'interpret the film' in the file menu of the sequence on the composition and I can't edit each clip manually in black and white because everything is in a sequence. Assembly of the entire sequence in black and white is not an option either because the 70s Film Noir scenes are also in the same room and are supposed to be full color. So how do AfterEffects to recognize the 20 silent film as in black and white?

  You have two choices. Shoot the film in black and white in After Effects and add film damage or restores the section black and white Prime Minister then apply film and AE damage. Almost all the effects, you first add will not come in AE using dynamic links, because they are not compatible. The only thing that you can do about it, it is to make your footage or all the effects work in AE.

  It is a workflow problem not a bug.

• export the video with alpha channel

  Hello

  I am brand new with Pro CC first. I completed a sequence where V1 has a series of still images, of small size, so I can see the video clip on the V2 in the background.

  I already exported only and it works very well.

  I would now like to export the clip on V1 by single with alpha channel so that I could put a different background in a new sequence.

  Read and followed the instructions as described in the forum, but they must use something different than what I use (first Pro CC on a laptop with windows 7 Professional), because I do not see the indicated settings.

  Once the clip is exported with an Alpha channel, I'll bring Premier Pro and everything just change the background several times so I will gradually in with several different sequences.

  How could I accomplish this export with an Alpha channel?

  Thanks for the info.

  Bert

  Hi Bert,.

  I think you have your tracks reversed, the stills would be on background on V1 and V2. Of course, if a SINGLE export with alpha and no background, then you can simply use V1 (but later, we clip you made must be V2 or higher to insert background on a bottom rail to show areas of the alpha channel). Export using QuickTime > GoPro 12-bit with Alpha codec.

  

  Thank you

• How to add an image to the alpha channels

  I want to add an image in black and white in this layer alpha https://gyazo.com/f3507eaa453f720bf7257ed9f7725404

  But I can't get a picture on it. Any help appreciated.

  1) press A ctrl or cmd - A on a Mac to select the content of your layer or simply select all from the menu bar.

  2 in your layers panel, select your alpha channel and then issue - special paste - paste in Place

  The contents of the layer doesn't have to be black and white as it will be converted to grayscale, but depends on the type of mask you're trying to do.

  Hope that helps

• Smaller files with an alpha channel

  I made a short video file in After Effects with an alpha channel of several different ways, but I can't to it go below 3 GB. Is it possible to get the smaller file without reducing the quality or the size of the composition? I would like to get the smaller file size to put in the cloud for use in a group project, and / 3GB is not really all that big a file, I have several files with an alpha channel that others need to access.

  The smallest file size with an alpha channel that is always the production quality would be a QuickTime JPEG 2000. Set the quality to about 85 to 90%.
