If your input is interlaced and is properly flagged, thus that Hybrid knows it is interlaced, you just need to set the encoder to encoder interlaced. Nothing more.
If your input is interlaced and not properly flagged, thus that Hybrid does not know it is interlaced, you need to properly overwrite the scan type to let Hybrid know. Then set the encoder to encoder interlaced.
The Interlaced option is only needed if your input is progressive, and you want Hybrid to interlace to a specific scan type "top field first" or "bottom field first".
Whether the output is interlaced !only! depends on the setting in the encoder.
