a low-level exception occurred in WebM (Importer:25)

[jbartosh_ndlb]

Hello community,

whenever I insert ANY webm files into my timeline I'm hit with dozens of errors with this line: "a low-level exception occurred in WebM (Importer:25)".

Kdenlive (the editor I moved from) can import, work with and render these exact same files absoltuely fine.  IS this something as simple as a codec install or what?  If I have to handbrake this stuff I migth as well have stuck with Kdenlive which never gives me an issue on importing anything.  Hoping someone knows an asnwer here, thanks!

Hello,

Try clearing the media cache and check if it fixes the issue.

Here are the steps: FAQ: How to clean (delete or trash) media cache files?

Nope that didn't do anything. This is a fresh install of Windows 11 and Premiere etc., so I didn't expect a cache issue would be the culprit.

Hi jbartosh_ndlb,

I don't think these files are supported now. Sorry about that. Check out this free plug-in. It may help: https://www.fnordware.com/WebM/

Thanks,

Ok yes the free plugin was the answer.
