It probably depends on the tracker and release group/uploader what they include in the torrent name, but yeah generally that's what you can filter by. Otherwise it requires access to the media-file to determine these things. I would say though, that good trackers have reliable information in the torrent names themselves, usually audio-tracks (sometimes just "multi" though), codec, and resolution. I only use private trackers now though, and I have not had issues with unexpected low quality video since moving away from public trackers.

I believe you can filter by tags too. These are tracker specific though, so it's up to the trackers you're using to define what you can filter with tags I think.

I'm pretty sure you can define the filter by bitrate as in dimension/minute of the file, this allow for a filter that's unrelated to the filename.

Of course if you are into stuff like HDR type you can't reasonably expect it to be tied to a webrip or anything below Blueray.

You can also do a manual search from within radarr and look at the files yourself.
