Invalid file extension

I've encountered this trying to upload a webm file with VP9/Opus encoding. I then tried a random .mp4 file on my computer. When uploading the error message screenshot in this thread, I again got the error being a webp file. A PNG uploaded successfully.

Webm support may sometimes be necessary to get around the 5MB file size limit, since VP9 and Opus have supperior compression which can be taken advantage of by manually using ffmpeg to run two passes. It really is amazing how good modern codecs are. Similar story with Webp for images; you get amazing compression better than jpeg, and also you get animation and transparency like gif.

I think someone else had suggested more file formats, so I will look into this! Thanks for the heads up!
