Undocumented Filters?

I’ve found that the “blur” filter exists even though it’s not in the documentation, and it seems to only work on text/html elements?

Are there other undocumented filters/effects/etc. I should know about?

Ha nice find.

That’s the only one undocumented. It’s quite compute intensive and we’re keen to optimise it before documenting it. Just be aware that your videos may time out if you use it too much.

It should work on images and videos.
