    MMm. My memory could be failing. 

    Older versions I could import a movie with straight alpha, turn off the alpha and the viewport showed me the straight alpha.

     

    But when I render out to prores (without alpha) and turn on straight alpha in render settings, i'm getting the results I want. 

    So it's good for now.

      I'm noticing when I render stuff out at 16bit with straight alpha (lossless+alpha or 4444+alpha) and I import the file and turn off the alpha (ignore settings in interpret footage). I'm not seeing the excess colors around the edges (specially on glows) like a straight alpha should give you!

      Would you be able to provide a project and screenshots demonstrating what you're describing here? It's possible that it's related to the same issue but it's difficult for us to determine without assets.

       

      quotesince WHEN did they add 'RGB STRAIGHT' to the viewport channels?

       

      These have been available as far as back I can remember, at least since CS6 and probably in earlier versions.

      Sigh!  since WHEN did they add 'RGB STRAIGHT' to the viewport channels?

      I can see the straight alpha now like I but in order versions I could render it like that 😞

      @JohnColombo17100380 I'm noticing when I render stuff out at 16bit with straight alpha (lossless+alpha or 4444+alpha) and I import the file and turn off the alpha (ignore settings in interpret footage). I'm not seeing the excess colors around the edges (specially on glows) like a straight alpha should give you!   I need this when I want to give matte/fill versions to clients. It elimnates the ugly dirty black haze with glows! Is this also the same issue ?? tested it on 2022 and there the straight alpha still works!

      Is Adobe's goal to break every single piece of software they make?

       

      Today, I needed to do somethinbg I do often.  Take an image with a mask and export as a tiff with a straight alpha.  When I do this, the image created is not the same as what I have set up in my comp.  Here is a simple example

       

      alpha premultiplied (correct looking image, but I need a straight alpha

       

      straight alpha

       WTF adobe?!?  this software has been around forevever and this is one of it's most basic feature.  

      Can you please just make your software work correctly?  This is supposed to be professional software, and this is far from professional functionality.

      I don't think I have enough information to reproduce this properly, but I tried making a simple comp with a couple of shapes, then exported one with premultiplied alpha and one with straight alpha, and they both came out looking the same. Admittedly I'm using AE 23.3, which may not be the same version you're using. 

       

      Can you try upgrading to the latest AE release? Can you share a project with the Render Queue setup to output the same way you are in your images?

        I am experiencing the exact same problem in the current version of AE (22.5.0). TIFF files with Straight alpha include misplaced layers and phantom elements from previous project files that aren't open. Premultiplied alpha renders fine. Thanks.
