Media Manager Displays Alpha Weird

  • 1.  Media Manager Displays Alpha Weird

    Posted 06-29-2023 12:40

    This is a problem that has happened in the past with PNGs, but I just move on. - In the attached screen shot you will see what media manager looks like in Dashboard.  Also attached you will see what the original PNG looks like.

    If I key the graphic on in an ME, it all keys correctly and ends up being correct.  But if I am only looking at the media player output, it looks like it does in the media manager page. - Is there a setting somewhere I can change to make these thumbnails look more like the real PNG, and not this white alpha of madness?

    Once adding the 2 images here, obviously it is hard to see the design.  There is an O logo on the left side.  The word media in Bars.  And then a numerical that in the attached example is the digit 1.

    The issue is that is how your Image for the Fill really looks ..

    this is how the media element is exported via your image editor.. since it is being exported as an Un Shaped Key type (Non Additive) media.

    Just look at the video channel and alpha channel in a MV or on a bus directly.

    I downloaded your "original" file and I loaded that to my Ultra and this is what I see in the thumbnail...

    It looks the same in a multi viewer or in a bus, until it is placed onto a key.  So if I do an auto select key with the media channel, and then put that keyer on air, it looks as I would expect it to look. - If I load the content into a Media Channel, says "M1", and then put M1 to a mutliviewer box, it looks the same in the multi viewer as it does in the media manager.

    That is in Graphite ...  So the Image you are posting here looks to be a different PNG than the one on your system ..  instead of Black where the alpha is having black yours still has White .. which happens with Photoshop sometimes if you don't define that other area to be black it puts white in it

    Then maybe the ross website is converting it in some way before you download it.  I literally took the file that I moved onto my USB drive and then attached it and uploaded it here.

    Carbonite Ultra running 7.1.0.9816

    I will try to download from the Ross website and re add into the carbonite and see if I get a different result.

    So yes, after I downloaded the image back from the web, then the image appears correctly in the Multiviewer and in Media Manager.

    The original image is just a photoshop file exported as a PNG.  I am not the creative type, I just needed some basic slates for a partner about to use our space.

    PSD File For Slates

    that link is a dropbox link to the original PSD file. - I simply exported as a copy from Photoshop as a PNG, and then transferred those PNGs to my flash drive, and then tried to open in media manager.

    Then it is for sure something in the file data that is modified when uploaded here to this community and then the file is different ....

    https://community.adobe.com/t5/photoshop-ecosystem-discussions/why-transparent-background-turns-white/m-p/12934977

    Need to look into what your setting it to when exporting to make sure it replaces the "transparent" area with black I guess..

    It for sure isnt the first adobe post.  My export is for sure exporting the alpha correctly. - I did try the 2nd adobe post about turning off the GPU.  That gave me the same results. - The file itself in a Mac and a PC have the transparency expected.  But when I upload to to the Carbonite, it does not have the transparency until it is put onto a keyer in a bus.

    Transparency is defined by the alpha channel .. and then the Keyer is removing the area that is Black .. grey is a transition to white being opaque..

    The image contains that white background in the Fill channel..  This has been seen many times before.

    Maybe try putting a layer on the bottom that is black??

    So by adding an dartboard it did give me something different, but still not correct.  Attached is a screen shot and then one version of an exported image as well. - In the screen shot.  On the left thumbnail that is an 8 bits of color space png, and on the right is 16 bits.  Just trying as many different things as possible.

    Yeah, up to 14 different ways of trying to save it as a PNG out of Photoshop.  Same results each time.  Looks fine in different operating systems and web browsers.  But Carbonite is not taking the properties correctly.

    https://www.dropbox.com/scl/fo/7h7jqp20vzdkdt077jac3/h?dl=0&rlkey=3nx1s8vrhtzifprmiui9ipid7

    This photoshop file is directly to the 14 different attempts of exporting in different ways.  Instead of uploading the PNG to the website and then someone downloading it and then it working.

    Broadcast video is 10 Bit .. so 16 bit is not going to do much either..

    Carbonite IS taking the properties correctly..  When it puts the image into video space it splits up the video and the alpha and create the 4:2:2 based exactly on the image..

    A OS or web browser may be able to interpret the content and display it how you would prefer it be seen..  However the image contains a channel that is telling it to display with white..

    The exporting from GIMP from the PSD you supplied also exports the PNG correctly..  There is a setting or something that causes this.. I wish I could nail it down for you but I can't..

    Could you please supply the "bad" export from photoshop via a dropbox link so that I can look at the file in an inspector please.
