saving a video with effects applied via vlc

In my previous post, I failed to save a video with effects. But now, this page showed me how to do it. The gui-based method is:

1. Show all settings (and not Simple) from Tools -> Preferences -> Interface settings
2. In Preferences, under Stream Output -> Sout -> Transcode, choose appropriate filter
3. From main menu, Media -> Convert/Save
4. Add input files, and choose Convert at bottom convert/save drop-down.
5. After doing required conversion, Tools -> Preferences -> Reset Preferences

Unfortunately, this method did not work out of the box with the vlc-based warp player made by Paul Bourke - the filter is not explicitly shown.
