Import transparent?

Question

I have a ton of webm files that have alpha channels and work in OBS and a friend made a transparent video frame with smoke over it for us to use that does indeed have an alpha channel but when I import it to premiere pro, it doesn't have an alpha channel. I had to install fnord's webm for premiere pro plugin to even import the webm but even so, I cannot use/import any videos with alpha.

Does anyone have any ideas how to get this working? I find it ridiculous that I've already spent a whole day looking for a solution with still no results. You'd think such a great video editor would have no problem doing this. 😕😕

Thanks in advance!

In doing some testing, it appears Premiere does not support reading WebM alpha channels. Bringing in a Webm with an alpha, Premiere reports it does not have an alpha. Even Mediainfo does not detect the alpha channel.

This is not due to a Premiere shortcoming, but an issue with the fNord Webm plugin.

However, Premiere (with the plugin) can properly export to WebM with an alpha channel.

OBS does correctly read the WebM alpha channels.

The WebM-Premiere plugin has not been updated since 2017. You can try to contact the developer here: https://github.com/fnordware/AdobeWebM
