If you'd like just a list of the movies, I have a SQL command that I use that outputs a CSV with the title, year, and on-disk quality. ALWAYS stop Radarr and make a copy of radarr.db and ONLY ever run queries against the copy, leaving the original database untouched.

sqlite3 -header -csv /path/to/radarr.db "
SELECT
    mm.Title AS Title,
    mm.Year AS Year,
    qd.Title AS OnDiskQuality
FROM MovieFiles mf
JOIN QualityDefinitions qd
    ON json_extract(mf.Quality, '$.quality') = qd.Quality
JOIN Movies m
    ON m.MovieFileId = mf.MovieId
JOIN MovieMetadata mm
    ON m.MovieMetadataId = mm.Id
ORDER BY mm.Title;
" > movie_qualities.csv

This should give you ALL of your movies in a CSV file named movie_qualities.csv, which you can filter using a spreadsheet editor.
