Converting files in VLC and applying filters

So I'm trying to convert an AVI file to something else. It's an AVI created in VLC, capturing input from a VCR and I'm having two strange problems.
First, VLC refuses to apply any filters I've selected (both in the preferences and in the effects / filters dialog).
Second, After it's done writing the file, it pops up a dialog and asks if I want to overwrite the file it just created. If I click yes, it writes it again. So far as I can tell, this is an endless loop.
I've run VLC from the terminal and observed no errors or warnings in the output.
Any suggestions?
Incidentally, I'm using the latest snap-packaged version of VLC on ubuntu 20.04

You might need to turn off hardware acceleration, depending on the filters.

Unfortunately, disabling hardware-acclerated decoding in the preferences had no effect.

Check the logs then.

Did that and, unfortunately, it didn't reveal much apart from a few warnings. I only had one filter active - color extraction.

Problem is that you're using streaming output instead of playing.

Ok. So apparently, it's not sufficient to just choose "convert/save" from the File menu and proceed through the dialogs. I take it there's a setting elsewhere I need to change? I poked through the preferences and nothing jumped out at me...

Filters preferences are for playback, not streaming output. This is working as expected.

Right. But the question is, how can I get filters to apply to a file conversion and not just playback within VLC?

VLC is a media player. It is not a filtering/converting/transcoding framework. Please use FFmpeg for this purpose.

Wrong, VLC also has these abilities.

It definitely does, the point I was attempting to make was that that doesn't appear to be its primary purpose and that I personally find FFmpeg to be better-suited for this purpose. Thanks!
