I did the update to Media Encoder and Premiere Pro 2020, Media Encoder has given me the option "include alpha channel" in "WebM" format befor the changeover from 2019. I tried to downgrade to 2019 but i still lost the option "include alpha channel". How do I get the option with include alpha channel back?

Don't know if this will help you, but it fixed it for me.

Go to add remove programs, uninstall the Web M plugin. Then redownload the plugin from fnordware.

When I did that it gave me the option for Alpha Channel back.

Same Issue! Anybody have any other solutions for encoding WebM with Alpha channels?

Thank you for the suggestion. I did remove the existing WebM plugin and then reinstalled. That fixed the problem.

One note, I was not able to remove it using uninstall program. I had to go the the directory C:\Program Files\Adobe\Common\Plug-ins\7.0\MediaCore and remove WebM.prm

I was able to get the checkbox back by uninstalling and re-installing, however, even when exporting with the "include alpha channel" box checked it does not actually export with the alpha channel for me. Did you attempt an export to confirm it actually exported with the alpha channel?

I am having the same problem. After upgrading to cc 2020 version, I lost the option to include alpha channel. When I tried to run on the earlier versions (which were still installed) the include alpha check box was on the export menu without the text describing what it was. I check the box, did the export, but there was no alpha channel on the resulting file.

I have no interest in 2020 specific functions. What can I do to get back to a working CC 2019 configuration?

Hmmm, I'm testing this in Premiere Pro 14.1.0 on Windows 10 Pro version 1903, and the checkbox is there, in the Video tab at the bottom of the Codec settings section. It's in Media Encoder too.

File a bug with Adobe?
