Opacity fades are not being exported

I am trying to re-edit a video in Premier Pro.  Using keyframes and opacity changes I am fading several video clips out.  Everything looks and plays well in the timeline but when I export, the opacity fades just snap to black.

 

This is happening on my laptop, and on my desktop with completely different project files.

I have tried the following;

Toggle Composite in linear colour.

Have tried using software encoding.

Have tried unchecking Maximum bit depth and maximum render quality.

Have tried rendering before export.

Have tried nesting.

Have tried checking Include Alpha

 

I am working with Notch LC

 

Thank you for any help.

    If you are fading to an empty track, the codec may be treating the fades as an alpha channel that is not applied during playback.

    To confirm, re-import the file into Premiere Pro, go to Clip > Modify > Interpret Footage, and check whether the file contains an alpha channel that can be enabled.

    Try fading to Black Video instead of an empty track and see if that resolves the issue.

    I think I’ve solved the issue. 

    I’m using Notch LC because it’s the codec we use in our servers.  The program I use to initially view the files is Quicktime7, as it plays NLC, albeit in a lesser quality.  However, QT will not show alpha, so when I’ve been viewing my exported files, it looks like the fades aren’t there.  It’s only when I tried one in the server that I saw the fades were actually included.

     

    Dropping a Black layer underneath everything and unchecking Alpha on the export seems to have everything looking correct in QT now.

     

    Sorry for the time wasting, but thank you for all the help.

    I’m not fading to black.  I’m using duplicated sections of the original track, layered on top.  Some of these duplicated layers fade to black to allow the original clip back in.

    As something else to try, be sure to delete the cache whenever you get a new version. And you can also delete your preferences to get a clean start between versions. Windows I assume?

    Did you try it with a non Notch codec? Usually you need to contact the 3rd party supplier for things like this.

    It was delivered to me as Notch LC, and we use NLC in the servers so I was hoping to not have to convert it.  I have NLC codec installed and use it all the time in ME and AE.

    I’ve tried exporting it to ME but the fades still don’t come through.  I could edit it in AE but it gets tedious not being able to play it back in real time (I’m editing to music).

     

    For the sake of experiment, I will convert it to something else and see what happens.
